The implant includes a screw portion, a flange and a soft tissue area. The screw portion is inserted into an alveolar bone. The flange is connected to the upper end of the screw portion and inserted into the alveolar bone. The flange has on the upper end thereof a waved shape that is concave in front and rear portions thereof and is convex in left and right portions thereof. The flange comprises on the circumferential surface thereof a fine threaded portion having a thread pitch and/or a thread height smaller and denser than those of the screw portion.

BACKGROUND OF THE INVENTION

The present application relates to a waved implant integrating a soft tissue area and an osseous tissue area and, more particularly, to a waved implant integrating a soft tissue area and an osseous tissue area that prevents fine motion of an artificial tooth, keeps the implanted vicinities clean of infection and preserves the gingival shape of the natural teeth.

2. Description of the Related Art

Generally, one of the functions specific to teeth is grinding food so that it can be digested easily. People who lose their teeth cannot chew food to promote good digestion. Accordingly, such people cannot eat their fill and cannot take in nutrition sufficient for staying in good health.

If a permanent tooth, i.e. a tooth exchanged for a milk tooth in childhood, is lost, a further tooth will not grow and take its place. Accordingly, it is necessary to restore the masticatory function by rehabilitating the lost tooth and its surroundings via a prosthetic dental treatment.

However, general dental treatments may somewhat damage the neighboring teeth, gums and osseous tissues. Even wearing dentures comes with the drawbacks that it decreases the masticatory function and they are a foreign body which causes inconvenience, and the like, compared with the natural teeth.

One of the solutions proposed to compensate for the drawbacks of the general prosthetic treatment is artificial tooth transplantation. Artificial tooth transplantation can almost fully restore the entirety of functions and the appearance of the natural tooth.

As described above, the artificial tooth is gaining in popularity recently as an artificial substitute for the natural tooth.

As depicted inFIGS. 1 and 2, the artificial tooth comprises a fixture (artificial tooth root)103, an abutment105and a process tooth107. The fixture103for supporting the process tooth107is anchored to an alveolar bone109in the vicinity of the lost tooth, like a tooth root in a natural tooth. The abutment105put in the gum couples the fixture103and the process tooth107. The process tooth107fixed on the abutment105in the mouth is designed to assume the same shape and provide the same function as the natural tooth.

Hereinafter, the process of transplanting an artificial tooth101to the space where the tooth was lost from will now be discussed.

The process of transplantation is roughly divided into a surgical operation and prosthetic rehabilitation.

Biocompatibility including a blood test, etc. is checked prior to the operation. The transplantation site is selected for the operation. An oral inspection, radiographic test, etc. are carried out in advance for evaluating the quality and quantity of osseous tissues at the transplantation site.

After a series of tests has been completed, the surgical operation is begun.

First, a primary operation is executed to transplant the fixture103corresponding to the tooth root of the natural tooth in the alveolar bone109under local anesthesia. Here, a gum111is excised to expose the alveolar bone109. Then, the fixture103is inserted into the alveolar bone109and the gum111is sutured.

After a lapse of 3 to 6 months depending on the osseous tissue, a secondary operation is carried out.

The gum111sutured is excised again to put the abutment105on the upper end of the fixture103. A connection screw115is inserted through an insertion hole113formed in the center of the abutment105. The connection screw115is engaged with an engagement hole117formed in the center of the fixture103, coaxial with the insertion hole113, to fix the abutment105on the upper end of the fixture103in the gum111. Like this, extruding the abutment105via the gum111in the mouth completes the secondary operation.

Subsequently, prosthetic treatment is performed.

First, a gold cylinder121is put coaxially on the upper end of the abutment105. Here, an upper extrusion119of the connection screw115is inserted into a lower penetration hole123having a shape of a truncated cone in the gold cylinder121. Then, the process tooth107is processed on the upper end of the gold cylinder121in a general manner. A gold screw129is inserted through a tooth hole127penetrating along with the centerline of the process tooth107. By engaging the gold screw129with an engagement hole125penetrating the upper end of the extrusion119of the connection screw115, the transplantation of the artificial tooth101is completed.

However, when applying the artificial tooth101, for example, to a front tooth, as depicted inFIG. 3, the portion B other than the alveolar bone A, excised to anchor the implant103to the alveolar bone A, does not have a supporter for adhering to, differently from the vicinity C of the fixture103. Accordingly, the alveolar bone B may be resorbed as time goes by and the gum111may be involuted.

The involution of the gum111has the following problems:

First, it widens the space between the artificial tooth and the gums or the space between the artificial tooth and the alveolar bone, which shortens the durability of the artificial tooth; and second, it widens the space between the artificial tooth and the gums or the space between the artificial tooth and the alveolar bone, which allows bacteria to infiltrate the space, thus causing an odor in and from the mouth and oral diseases.

SUMMARY

Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a waved implant integrating a soft tissue area and an osseous tissue area which reduces the space between an artificial tooth and an alveolar bone to prevent the resorption of the alveolar bone and the involution of the gums, thus prolonging the durability of the artificial tooth, and preventing the deformation of the gums, mouth odors and oral diseases.

Another object of the present invention is to provide a waved implant integrating a soft tissue area and an osseous tissue area in which the edge of the upper end of the implant has a saddle shape to correspond to an alveolar bone and a gum of a patient, so that the alveolar bone surrounding the implant, in particular, the upper portion of the alveolar bone, can be closely adhered to the upper end of the implant without forming a gap, thus reliably preventing the resorption of the alveolar bone.

A further object of the present invention is to provide a waved implant integrating a soft tissue area and an osseous tissue area in which a plurality of microthreads is formed in the circumferential outer surface of the upper end of the implant within a predetermined width, thus increasing the coherence to the gum and a cortical bone formed above the alveolar bone.

In order to accomplish the above objects, the present invention provides a waved implant integrating a soft tissue area and an osseous tissue area, the implant being connected at an upper end thereof to a process tooth, the implant including: a screw portion inserted into an alveolar bone; a flange connected to an upper end of the screw portion and inserted into the alveolar bone, the flange having on an upper end thereof a waved shape that is concave in front and rear portions thereof and is convex in left and right portions thereof, the flange comprising on a circumferential outer surface thereof a fine threaded portion having a thread pitch and/or a thread height smaller and denser than those of the screw portion, with a plurality of waved microthreads formed on the fine threaded portion; and a soft tissue area combined with an upper end of the flange in a body.

Therefore, in the waved implant according to the present invention, the flange having a waved shape and the soft tissue area are integrally formed with the implant, thus preventing fine motion of the implant, preventing infiltration of bacteria around the implant, and keeping the gum in the shape it was in when holding the natural tooth.

The screw portion may comprise a triangular screw or a rectangular screw, but it is not limited to this.

The surface of the microthreads may be treated to have an average surface roughness in μm units, preferably about 0.5 μm to 2 μm. The surface treatment of the microthreads may be conducted by a blasting, etching or anodizing method, but it is not limited to these.

The waved shape of the flange corresponding to the shape of the upper end of the flange may be formed dually around the circumferential outer surface of the flange having the microthreads.

The shape of the upper end of the soft tissue area may be formed identical with that of the upper end of the flange.

The shape of the upper end of the soft tissue area may be that of a polygon having ears.

The shape of the upper end of the soft tissue area may be even.

The shape of the soft tissue area may be a waveform.

Furthermore, the portion between the soft tissue area and the flange may have a slender shape, referred to as Monroe's waist, which is curved sharply from the flange in an upper and inner direction and extended to the soft tissue area. Here, the angle between the flange and the soft tissue area is about 10° to 90°.

The soft tissue area has the same composition as the osseous tissue area.

DETAILED DESCRIPTION

FIG. 4is a front view depicting the transplantation of a waved implant integrating a soft tissue area and an osseous tissue area in the site of a front tooth, in accordance with an embodiment of the present invention. As depicted inFIG. 4, an implant3comprises a screw portion13, a flange15connected with the upper end of the screw portion13and a soft tissue area22aintegrated with the upper end of the flange15.

The implant3is installed in an alveolar bone9by means of the screw portion13. The screw portion13includes a thread17and a cutting edge14.

A triangular screw is generally used, however, a rectangular screw may be used to increase the coherence, which is, however not limited.

In a preferred embodiment of the invention, the upper part of the screw portion13has an outer diameter of about 3.0 to 5.0 mm and the lower part of the screw portion13has an outer diameter of about 1.0 to 3.0 mm, thus having a shape of a rectilinear body becoming rapidly smaller in the region of the lower part. The thread17of the screw portion13having a thread depth of about 400 μm, a thread pitch of about 800 μm and an inclined structure at an upward angle of 0° to 10° are formed on the circumferential surface. Accordingly, the implant3can be installed in bone tissue by the rotation of the screw portion13.

The cutting edge14is formed by cutting off both ends of the lower part of the screw portion13at an angle of about 90 degrees to enhance the installation stability of the implant3. The cutting edge14may increase the bone mineral density in the vicinity of the screw portion13since it compresses the vicinity of the screw portion13according to the insertion of the implant. At the same time, it is possible to reduce the time required for the bone tissue to adhere to the implant.

In this embodiment, the flange15is inserted into the cortical bone9′ on the alveolar bone9. The upper end of the flange15is a curved polygonal shape, such as a trigonal or tetragonal shape, having ears for preventing the involution of the gums. Besides, the upper end of the flange15may be formed variously having a wave or sinusoidal wave, a chopping wave or triangular wave, etc. Accordingly, the upper end of the flange15may perform a role that prevents the flange15of the implant3from being resorbed into the alveolar bone, which may happen after the insertion of the implant. For example, if the upper end of the flange15is formed in the shape of a waved edge (Taeguk edge), the shape may have a waveform where the front and the rear are concave and the right and the left are convex or a waveform where the front and the rear are convex and the right and left are concave.

Microthreads21are densely formed on the body of the flange15. The microthreads21strengthen the coherence with the cortical bone9′ and, at the same time, disperse stress generated during the use of the implant3. For this purpose, the microthreads21having a thread depth and/or a thread pitch smaller than those of the thread17of the screw portion13are formed densely. For example, the microthreads21have a thread depth of about 1 to 25 μm, a thread pitch of about 200 to 400 μm and an upward angle of 0° to 5° and are formed on the circumferential surface of the flange15.

As shown inFIG. 7, in the case where the microthreads21have the same shape as the upper end of the flange15, valley portions of the microthreads21are prevented from being exposed to outside of the surface of the upper end of the flange15. In this case, the surface of the upper end of the flange15can be formed to have a smooth shape. Hence, a risk of damaging a gum11around front teeth can be reduced, compared to the case where valley portions of the microthreads21are exposed to outside of the surface of the upper end of the flange15.

Here, the microthreads21may be formed to have a rectilinear shape inclined at an upward angle of 0° to 5°, or to have the wave edge or the triangular wave like the upper end of the flange15over the circumferential surface of the flange.

In particular, it is desirable that the surface of the microthreads21be processed roughly to prevent the involution of the gums. The surface treatment of the microthreads21may be processed via blasting, etching, anodizing and the like, which is, however, not limited. Examples will be described in detail hereinafter.

The sand blasting method is directed to a surface treatment that reforms the surface of the microthreads21roughly by injecting sand or fine sand, such as silica, under high pressure.

Grit blasting method is a surface treatment method that increases the blasting effect on the surface of the microthreads21using grits having a sharp edge made by crushing nodular cast iron instead of sand or fine sand.

The etching method corrodes the surface of the microthreads21using chemicals to make it rough and uneven.

The surface of the microthreads21may be processed by one of the above methods to generate an average surface roughness in the units of μm, preferably, of about 0.5 μm to 2 μm.

Meanwhile, the anodizing method is a surface treatment that anodizes surfaces of aluminum alloy, magnesium alloy, titanium alloy, etc. For example, a metal to be processed is coupled to an anode and an inert metal is connected with a cathode in electrolyte. Then, an electric current is applied to the electrodes to form oxidized films on the surfaces of aluminum, magnesium, titanium, etc. Accordingly, it is possible to increase the corrosion resistance by preventing further oxidizations to the inside of the metal.

In particular, the flange15is divided into a contact portion15acontacting with the cortical bone9′ on the alveolar bone9and a contact portion15bcontacting with the gum11. An end portion B of the cortical bone9′ may adhere well to the contact portion15acontacting with the cortical bone9′ by means of the microthreads21and their rough surface. Besides, the flange15may be combined well with the process tooth by means of the microthreads21having the waved edge.

In this embodiment, the soft tissue area22amay be formed in a polygonal shape such as a trigonal, tetragonal, pentagonal, or hexagonal shape, having ears connected with the flange in a body. The ears of the soft tissue area22aextend to the upper end of the gum11. Accordingly, the end portion B of the cortical bone9′ that is a portion remaining after excision, is not resorbed. Besides, a top end portion D of the gum11does not involute. Furthermore, since the gum does not involute, it is possible to prevent bacteria from infiltrating between the artificial tooth and the gum11or between the artificial tooth and the alveolar bone9, and to keep the form of the gum of the natural tooth.

Here, the top end portion D of the gum11may make contact with the contact portion15bwhich makes contact with the gum11and the soft tissue area22aat the same time.

Moreover, since the soft tissue22ais extended to the upper end of the gum11in a body, the installation operation of a process tooth, not depicted, may be readily performed. That is, because the process tooth is installed on the soft tissue area22ahaving the integrated structure, the artificial tooth can be seated without fine motion and prevent the gums from involuting additionally to keep the shape of the gum11of the natural teeth, thus increasing the aesthetics of it.

The angle between the soft tissue area22aand the flange15may be adjusted to from 10° to 90° depending on the shapes of the process tooth and the soft tissue area22a. The angle between the soft tissue area22aand the flange15is formed so that the junction between the soft tissue area22aand the flange15can be effectively closed. Accordingly, it is possible to enhance the stability of soft tissue and, at the same time, to prolong the durability or lifetime of the artificial tooth.

Besides, the composition of the soft tissue area22ais identical with that of the osseous tissue area; however, the surface of the soft tissue area22amay be even so that the surface treatment is not done, after a turning. Here, the composition of the soft tissue area22aincludes hydroxyapatite, etc., which is, however, not limited thereto.

FIG. 5is a side view ofFIG. 4. As depicted inFIG. 5, the upper end of the flange15is formed of a polygonal shape having a vertex and the soft tissue area22ahas the same shape as the flange15, thus preventing the fine motion of the implant3.

Since the soft tissue area22ais integrally formed with the implant3and the flange15having the waved shape is extended to the gum11, it is possible to prevent the resorption of the cortical bone9′ and the involution of the gum11due to the excision, thus preventing the infiltration of bacteria.

Furthermore, the portion between the soft tissue area22aand the flange15may have a slender shape, referred to as Monroe's waist, which is curved sharply from the flange15in an upper and inner direction and extended to the soft tissue area22a. Thereby, it is possible to increasingly prevent the involution of the gum11.

Meanwhile,FIG. 6is a side view depicting transplantation of a waved implant integrating a soft tissue area and an osseous tissue area in a front tooth site, in accordance with another embodiment of the present invention. As depicted inFIG. 6, the upper end of the flange15has a hemispheric shape and the lower end has a waved shape, thus preventing fine motion of the implant3. The upper end of the soft tissue area22bis planar. Since the soft tissue area22bis integrally formed with the implant3and the flange15having a hemispheric shape in the middle is extended to the gum11, it is possible to prevent the resorption of the cortical bone9′ and the involution of the gum11due to the excision, thus preventing the infiltration of bacteria.

FIG. 6shows the microthreads21of the flange15formed rectilinearly;FIG. 7depicts the microthreads21of the flange15formed in a waved shape or sinusoidal shape; andFIG. 8illustrates the microthreads21of the flange15formed in a chopping wave or triangular wave.

The other conditions of this embodiment are identical with those described with reference toFIGS. 4 and 5.

FIGS. 9 through 11illustrate modifications ofFIGS. 6 through 8, wherein a dual wave is formed on the circumferential surface of the flange15. As shown inFIGS. 9 through 11, the upper end of the flange15having the dual wave is formed hemispheric and the lower end of the flange15is formed in a dual wave shape, thus further preventing the fine motion of the implant3. Since the soft tissue area22bis integrally formed with the implant3and the flange15having a hemispheric shape in the middle is extended to the gum11, it is possible to prevent the resorption of the cortical bone9′ and the involution of the gum11due to the excision, thus preventing the infiltration of bacteria. The upper end of the soft tissue area22bhas a flat shape.

That is, since the flange15has the dual wave shape, it provides resistance to the fine motion of the implant3, resorption of the cortical bone9′ and the involution of the gum11larger than the flange15having a single waved shape.

The boundary of the waved shape may be that between the cortical bone contact portion15aand the gum contact portion15bor may be an upper or lower portion.

FIG. 9shows the microthreads21of the flange15having the dual wave formed rectilinearly;FIG. 10depicts the microthread21of the flange15having the dual wave formed in a waved shape or sinusoidal shape; andFIG. 11illustrates the microthreads21of the flange15having the dual wave formed in a chopping wave or triangular wave.

The other conditions of these modifications are identical with those described with reference toFIGS. 6 and 8.

FIG. 12is a side view showing transplantation of a waved implant integrating a soft tissue area and an osseous tissue area in a front tooth site, in accordance with still another embodiment of the present invention. As shown inFIG. 12, since the flange15is formed in a waved shape and the soft tissue area22cis formed in a waved shape as well, it is possible to further prevent the fine motion of the implant3. Furthermore, because the soft tissue area22cis integrally formed with the implant3and the flange15having a waved shape is extended to the gum11, it is possible to prevent the resorption of the cortical bone9′ and the involution of the gum11due to the excision, thus preventing the infiltration of bacteria.

The other conditions of this embodiment are identical with those described with reference toFIGS. 4 and 5.

FIG. 13is a side view showing a modification ofFIG. 12, wherein a dual wave is formed on the circumferential surface of the flange15. As shown inFIG. 13, since the flange15is formed in a waved shape and the soft tissue area22cis formed in a waved shape as well, it is possible to further prevent the fine motion of the implant3. Furthermore, because the soft tissue area22cis integrally formed with the implant3and the flange15having a waved shape is extended to the gum11, it is possible to prevent the resorption of the cortical bone9′ and the involution of the gum11due to the excision, thus preventing the infiltration of bacteria.

That is, since the flange15has the dual wave shape, it provides resistance to the fine motion of the implant3, resorption of the cortical bone9′ and the involution of the gum11larger than the flange15having a single wave shape.

The boundary of the waved shape may be that between the cortical bone contact portion15aand the gum contact portion15bor may be an upper or lower portion.

The other conditions of this modification are identical with those described with reference toFIGS. 9 and 11.

Meanwhile,FIGS. 15 and 16illustrate a waved implant integrating a soft tissue area and an osseous tissue area in a front tooth site, in accordance with still another embodiment of the present invention. As shown inFIGS. 15 and 16, the implant3includes a screw portion13which is screwed into an alveolar bone9, and a flange15which is coupled to the upper end of the screw portion13and is in contact with a gum11.

Here, the structure of the screw portion13is not limited to a special structure, so long as it can be screwed into the alveolar bone9. Typically, a triangular screw is used for the structure of the screw portion13, however, a rectangular screw may be used to increase the coherence, as shown inFIG. 15.

In particular, in the waved implant of the present invention, the upper end of the flange15generally has a smoothly curved saddle shape wherein the front and the rear are concave and the left and right are convex, such that it corresponds to the contour of the alveolar bone9into which the implant3is transplanted.

Furthermore, the implant3according to this embodiment of the present invention has microthreads21which are densely formed on the circumferential outer surface of the upper end of the flange15which is in contact with the gum11and has a thread pitch of 400 μm, thus enhancing the coherence to the tissue of the gum11.

Moreover, as shown inFIG. 17, a fine threaded portion19may be further formed on the circumferential outer surface of the flange15. A thread formed on the fine threaded portion19has a thread pitch and/or thread height less than that of the thread17of the screw portion13, in other words, it is relatively dense. Preferably, the thread of the fine threaded portion19comprises a triangular screw to reduce reaction force against the adjacent gum11or alveolar bone9.

FIG. 18illustrates a waved implant integrating a soft tissue area and an osseous tissue area in a front tooth site, in accordance with still another embodiment of the present invention. As shown inFIG. 18, in the implant according to this embodiment, the upper end of the flange15engages with the cortical bone9′ which is the upper portion of the alveolar bone9, and microthreads21are formed on the circumferential outer surface of the flange15. Preferably, the flange15has on the circumferential outer surface thereof a fine threaded portion19which has a pitch and/or a thread height less than that of the thread of the screw portion13. The fine threaded portion19engages with the cortical bone9′ of the alveolar bone9.

FIGS. 19 and 20illustrate a waved implant integrating a soft tissue area and an osseous tissue area, in accordance with still another embodiment of the present invention. As shown inFIGS. 19 and 20, in this embodiment, an alveolar bone contact portion15awhich engages with the cortical bone9′ of the alveolar bone9is formed on the circumferential outer surface of the lower end of the flange15. A gum contact portion15bwhich engages with the gum11is formed on the circumferential outer surface of the upper end of the flange15. The alveolar bone contact portion15ahas microthreads21and, preferably, it has a fine threaded portion19which has a pitch and/or a thread height less than that of the thread of the screw portion13. Thus, the alveolar bone contact portion15acan be reliably adhered to the cortical bone9′ of the alveolar bone9. The gum contact portion15bwhich engages with the gum11has an even surface which is not rougher than the microthreads21or the fine threaded portion19, such that it is reliably adhered to the top end portion D of the gum11. An annular groove25is formed in the circumferential outer surface of the junction between the alveolar bone contact portion15aand the gum contact portion15b.

The effect of the waved implant integrating the soft tissue area and the osseous tissue area according to the present invention having the above-mentioned structure will be explained below.

The implant3of the present invention is screwed into the alveolar bone9through the screw portion13formed on the circumferential outer surface thereof, in the same manner as that of the general implant of the artificial tooth. The cutting edge14which functions to bore the alveolar bone9is formed in the lower end of the implant3. In the embodiments, although a rectangular thread has been illustrated as being used as the thread17of the screw portion13, other kinds of threads, for example, a triangular thread, may be used.

In particular, the implant3of the present invention has on the upper end thereof a saddle shape so that the left and the right are convex to correspond to the shape of the adjacent alveolar bone9or gum11. In addition, the front and the rear portions of the upper end of the implant3are concave. Thus, the implant3can be supported even on the end portion B of the cortical bone9′ of the alveolar bone9through the flange15. Hence, the present invention can prevent the resorption of the end portion B of the cortical bone9′ and the involution of the gum11which is disposed above the end portion B.

Furthermore, as shown inFIGS. 17 and 18, the screw portion13has a rectangular thread to increase the coherence, with the result that reaction force applied from the screw portion13to the adjacent alveolar bone is increased. However, in the present invention, the microthreads21may be formed on the circumferential outer surface of the flange15which is in contact with the surface layer of the alveolar bone9at which the cortical bone9′ is disposed, and, preferably, the fine threaded portion19having a triangular thread may be formed thereon. Therefore, the microthreads21or the fine threaded portion19can be more densely adhered to the cortical bone9′ of the alveolar bone9and the reaction force applied from fine grooves or the fine threaded portion19can be relatively reduced. As a result, the resorption of the alveolar bone9which is adjacent to the flange15can be prevented.

As well, as shown inFIGS. 19 and 20, in the case where the gum contact portion15bis formed on the upper end of the flange15in which the front and the rear are concave and the left and the right are convex, the end portion B of the cortical bone9′ of the alveolar bone9engages with the alveolar contact portion15aof the flange15on which the microthreads21and the fine threaded portion19are formed, thus increasing adhesion force between the flange15and the alveolar bone9. Furthermore, the gum contact portion15bis in contact with the soft tissue area which is the end portion D of the gum11, thus increasing adhesion force between the gum contact portion15band the soft tissue area of the gum11. Thereby, the present invention can prevent the infiltration of bacteria between the implant3, the alveolar bone9and the gum11after the surgically placing the implant, and the resorption of the cortical bone can be prevented. In addition, the implant3of the present invention can be reliably adhered to the alveolar bone9and the gum11. Particularly, in the case where the annular groove25is formed between the alveolar bone contact portion15aand the gum contact portion15bof the flange15, connective tissue which is the fibroblast of the gum11coheres in the annular groove25, thus increasing the adhesion force between the implant3and the soft tissue of the gum11.

Meanwhile, as shown inFIGS. 21 through 24, the soft tissue area22may have a trumpet shape which increases in diameter from the bottom to the top. This can be implemented by tapering the inner and outer surfaces of the soft tissue area22. As such, in the case where the soft tissue area22has a trumpet shape which is increased in diameter from the bottom to the top, a connection screw (not shown) can be easily coupled to the implant3after the implant transplantation is completed.

Furthermore, the present invention may be constructed such that a wrench coupling part30is provided in the flange15. In this case, the implant3can be easily transplanted into or removed from the gum by fitting the wrench (not shown) into the wrench coupling part30and rotating the wrench. The wrench coupling part30may be formed through a punching process, which is, however, not limited thereto. In addition, the wrench coupling part30may have various shapes, for example, a pentagonal shape, a hexagonal shape, an octagonal shape, etc., and it is not limited to a special shape, so long as the wrench (not shown) can be fitted thereinto.

As such, in the present invention, the cortical bone9′ of the alveolar bone9can be satisfactorily formed by the alveolar bone contact portion15a. The gum contact portion15bcan be reliably adhered to the soft tissue of the gum11by cohering of the connective tissue of the gum11in the annular groove25. Therefore, the implant3can be reliably adhered to the gum11and the alveolar bone9, and the infiltration of bacteria can be prevented, thus making the transplantation of the implant3smooth and reliable.

As described above, since the waved implant integrating the soft tissue area and the osseous tissue area in accordance with the present invention is integrally installed in a bio or artificial soft tissue after a corresponding portion of a gum is excised and sutured, it prevents the resorption of alveolar bone and the involution of the gum, thus preventing the infiltration of bacteria, and maintains the implant clear. Furthermore, it is possible to keep the implant installed for a longer time, which saves time and money, and to increase looks by restoring the gums to their state when the natural tooth was present.

Moreover, in the present invention, the edge of the upper end of the implant has a saddle shape to correspond to the alveolar bone and the gum of the front tooth site. Therefore, the alveolar bone surrounding the implant can closely adhere to the implant without forming a gap therebetween, thus reliably preventing the resorption of the alveolar bone and the involution of the gum. As well, a plurality of fine grooves or a fine threaded portion is formed on the circumferential outer surface of a portion of a flange which is in contact with the cortical bone of the alveolar bone, and a relatively even surface is formed on the circumferential outer surface of a portion of the flange which is in contact with the gum. Thereby, the flange can be reliably adhered to by the cortical bone of the alveolar bone and the gum, thus increasing the coherence to the alveolar bone and the gum surrounding the implant.
