Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a dental carrier, and more particularly, to a dental carrier for shaping the correct and suitable shape according to the dentition and leading the loading (medicament or dental hygiene health and beauty related materials) to be evenly and precisely coated on the teeth, root, gum or periodontal tissue to be treated. 
         [0003]    2. Description of the Prior Art 
         [0004]    The medicament such as antibiotics used in periodontal treatment or dental hygiene health and beauty related materials, such as fluoride gel and whitening medicament, are often needed to be coated on the teeth, root surface and gum tissue of the mouth by using tools. Currently, the tools used on the market commonly are brush, cotton rolls, or dental tray. The medicaments are often interfered or diluted by the tongue or saliva flow using these tools, and the medicaments also move away from the area to be coated in the mouth with the effect of gravity or the position of the teeth. Furthermore, the conventional cotton rolls or dental trays are loosely attached to the teeth, thereby often resulting in inconvenience and uncomfortable to the user, reducing the effect of the medicament and increasing the dosage of the medicament. 
         [0005]    The conventional dental tray is a carrier that places medicament or dental hygiene health and beauty related materials (such as whitening medicament and fluoride coating), and the medicament or the hygiene related materials can be confined to the space near the teeth by the carrier. Currently, there is a kind of dental tray, and the principle of the dental tray is to use the characteristic that the thermoplastic material can be any deformation after heating. Thus, one may heat the dental tray and then use the solid teeth to set the shape while the thermoplastic material has not yet completely cooled, therefore the dental tray can be created correctly and suitably according to different individuals, so that the dental tray can be firmly adhered to the surrounding teeth. However, the present design makes the gap between the dental tray and the convex surface of the teeth surface very small, and the gap between the teeth gap and the concave surface of the teeth root becomes large, so that the medicament or the hygiene health related materials cannot be evenly coated on the area to be treated (such as the teeth surface or the teeth root), and the medicament also flows away from the area to be coated with the gravity or the position of the teeth in the mouth, thereby resulting in inconvenience to the user (the medicament coating people and coated people), uncomfortable situation, the reducing effect of the medicament and the increasing dosage of the medicament. 
         [0006]    The U.S. Pat. No. 5,562,449, 5,616,027 and 5,769,633 belong to a series of dental tray patents, and the concept of a double-layer dental tray provided by these prior arts has a horseshoe-shaped exterior and an U-shaped cross section that are similar to the arrangement of human teeth shape, and the outer tray is a resilient material that can be used to support the inner tray; the inner tray is a thermoplastic material and the inner tray becomes more plastic when being heated to 145-160° F., therefore, when the patients press the inner tray with the teeth, a more accurate dentition shape can be printed out. 
         [0007]    Besides, the ROC Patent No. M441456 proposes a dental tray-type oral health care film, and the technical characteristic is a double-layer dental tray comprising a thin layer and a shaping layer, wherein the thin layer can comprise a medicament or other dental care materials for contacting the teeth, and the shaping layer can be shaped in accordance with the individual dentition for allowing the thin layer to be firmly adhered to the teeth. 
         [0008]    However, in the prior art, when the medicament for treating the teeth is coated in the molded double-layer dental tray, because the dental tray is too closely adhered to the teeth surface, the medicament cannot be guided to the area to be treated and is hard to be evenly coated on the area to be treated. 
       SUMMARY OF THE INVENTION 
       [0009]    Therefore, to solve the above-mentioned problems, the present invention provides a dental carrier for shaping the correct and suitable shape according to the teeth or alveolar ridge of the human to be firmly adhered to the teeth, and the amount of space between the teeth and the dental carrier can be adjusted in a suitable area of the dental carrier by the design of the pattern structure to lead the loading (medicament or hygiene health and beauty related materials) to be evenly and precisely coated on the teeth, periodontal tissue, alveolar ridge or area to be treated, while the dental carrier can also meet the needs to be firmly adhered to the teeth, therefore the dental carrier can improve the effectiveness of treatment. When the dental carrier is not used to carry the medicament, the pattern structure can improve the mechanical strength and fitness of the dental carrier to be used as a mouth guard in sports, biteplate, periodontal dressing, teeth fixation, orthodontic retainer or protection for the teeth, root, periodontal tissue or alveolar ridge.

         [0035]    Wherein, the thermoplastic carrier is selected from a group comprising ethylene vinyl acetate (EVA), polyethylene (PE), polypropylene (PP), polyester (POLYESTER), polyvinyl chloride (PVC), polystyrene (PS), polymethylmethacrylate (PMMA) , Polycarbonate (PC), polyethylene terephthalate (PET), nylon (nylon), polytetrafluoroethylene (PTFE), polyurethane (PU), polyoxymethylene (POM), porous materials and the combination thereof. 
         [0036]    Furthermore, as shown in  FIG. 3  (A) to (C),  FIG. 3  (A) to (C) shows a schematic diagram of the pattern structure respectively in an embodiment of the present invention. The inner surface S 1  of the thermoplastic carrier  12  has a sidewall  124 , and the pattern structure  122  is configured on the sidewall  124 . In the present invention, the pattern structure  122  comprises a cavity structure  1221 , as shown in  FIG. 3  (A), and a trench structure  1222 . The trench structure comprises two embodiments, one is a lateral trench structure  1222  as shown in  FIG. 3  (B), and the other one is a longitudinal trench structure  1223  as shown in  FIG. 3  (C). In the practical application, the pattern structure  122  can be selected from a group comprising the cavity structure  1221 , the lateral trench structure  1222  and the longitudinal trench structure  1223  and any combination thereof; however, the present invention is not limited to it, in addition to the above-mentioned lateral trench structure  1222  and longitudinal trench structure  1223 , the trench structure can also comprise an oblique trench structure, a helical trench structure, and a serrated trench structure. 
         [0037]    In an embodiment of the present invention, when the cavity structure  1221  is used as the pattern structure  122 , the thermoplastic carrier  12  can be heated with the outer tray  10  after the dental carrier  1  is synthesized from the thermoplastic carrier  12  and the outer tray  10 , or the thermoplastic carrier  12  can be heated alone, for example, after the thermoplastic carrier  12  is heated to be soft, the surface of the thermoplastic carrier  12  is slightly cooled in few seconds, and then a user will put the dental carrier  1  into the mouth to be impressed by teeth or alveolar ridge, so that the dental carrier  1  can form teeth or alveolar ridge model of the user to achieve the effect of the present invention. 
         [0038]    Next, fill the inner surface S 1  comprising the cavity structure  1221  with a medicament to be applied to the teeth, root, alveolar ridge or periodontal tissue to allow the user to directly impress the present invention, so that the teeth, root, alveolar ridge or periodontal tissue can be closed to the inner surface S 1  comprising the cavity structure  1221 , and the medicament can be uniformly applied to the teeth, root, alveolar ridge or periodontal tissue of the user. Wherein, the medicament comprises a whitening medicament, a mouthwash, and a medicament for the treatment or maintenance of teeth, root, alveolar ridge or periodontal tissue. 
         [0039]    The shape of the cavity structure  1221  comprises a triangular, circular, square, elliptical and polygonal shape. In addition to the arrangement shown in  FIG. 3(A) , the arrangement of the cavity structure further comprises a honeycomb arrangement. 
         [0040]    Please refer to  FIG. 3  (B) to (C) again. In another embodiment of the present invention, the dental carrier  1  uses the lateral trench structure  1222  and the longitudinal trench structure  1223  as the pattern structure  122  respectively, as shown in  FIG. 3  (B) and  FIG. 3  (C) respectively. The cross-sectional shape of the lateral trench structure  1222  and the longitudinal trench structure  1223  is semi-circular shape. However, the cross-sectional shape of the trench structure comprises a zigzag shape, a semi-circular shape, an upside-down U shape, a semi-elliptical shape and a non-closed polygonal shape. In the embodiment of the present invention, the same as mentioned above, the thermoplastic carrier  12  can be heated with the outer tray  10  after the dental carrier  1  is synthesized from the thermoplastic carrier  12  and the outer tray  10 , or the thermoplastic carrier  12  can be heated along, after the surface of the thermoplastic carrier  12  is slightly cooled, a user will put the dental carrier  1  into the mouth to be impressed by teeth or alveolar ridge, so that the dental carrier  1  can form teeth or alveolar ridge model of the user to achieve the effect of the present invention. 
         [0041]    Next, fill the inner surface S 1  comprising the lateral trench structure  1222  or the longitudinal trench structure  1223  with a medicament to be applied to the teeth, root, alveolar ridge or periodontal tissue to allow the user to directly impress the present invention, so that the teeth, root, alveolar ridge or periodontal tissue can contact with the inner surface S 1  comprising the lateral trench structure  1222  or the longitudinal trench structure  1223 , and the medicament can be evenly applied to the teeth, root, alveolar ridge or periodontal tissue of the user. Wherein, the medicament comprises a whitening medicament, a mouthwash, and a medicament for the treatment or maintenance of teeth, root, alveolar ridge or periodontal tissue. 
         [0042]    In the above-mentioned embodiment, the thermoplastic carrier  12  must be used with the outer tray  10  in the dental carrier  1 , but in the practical application, the thermoplastic carrier  12  can also be directly used as the dental carrier  1  of the present invention, so that the outer tray  10  is not required at this time. The user can use the thermoplastic carrier  12  coated with the medicament and having been customized by the user to be impressed by teeth directly as shown in  FIG. 3  (A) to (C). 
         [0043]    Furthermore, the pattern structure  122  can also be formed on the outer surface S 3  of the thermoplastic carrier  12 , as shown in  FIG. 3  (A) to (C), in the embodiment of the present invention, the lateral trench structure  1222  is formed on the outer surface S 3 , for the sake of the clean and clear of the figures, only one lateral trench structure  1222  is drawn on the outer surface S 3  as the representative, in the practical application, a plurality of lateral trench structures  1222  or other types of the pattern structures  122  can be formed on the outer surface S 3 . Wherein each trench of the trench structure formed on the outer surface S 3  belongs to a closed trench or culvert to avoid the leakage of the medicament from the trench structure to the outer surface S 3 ; while the trench structure formed on the sidewall  124  is open trench or open channel. 
         [0044]    The pattern structure  122  formed on the outer surface S 3  of the thermoplastic carrier  12  is connected to the pattern structure  122  on the inner surface S 1  by a perforation (not shown in figures) for the purpose of medicament guidance, take  FIG. 3  (A) for example, the lateral trench structure  1222  is connected to the cavity structure  1221  on the inner surface S 1  by a perforation running through the sidewall  124  (not shown in figures), in the embodiment of the present invention, the user can place the medicament in the lateral trench structure  1222  on the outer surface S 3 , so that the medicament can be led to the cavity structure  1221  on the inner surface S 1  via the perforation, thereby allowing the medicament to be led to the area to be treated such as teeth, root or periodontal tissue. Otherwise, the thermoplastic carrier  12  can be formed from a porous material, thereby allowing the medicament to be led to the cavity structure  1221  on the inner surface S 1  from the lateral trench structure  1222  on the outer surface S 3  via the porosity of the material of the thermoplastic carrier  12 . 
         [0045]    The above-mentioned pattern structure  122  has the function of storing the medicament and leading the medicament to the area to be treated such as teeth, root or periodontal tissue. In the practical application, the user can only apply the medicament on the partial pattern structure  122  to treat the partial position of the teeth, root or periodontal tissue of the user. However, the pattern structure  122  of the present invention is not necessary to be covered the sidewall  124  or the outer surface S 3  all over, and the design of the present invention also allows the pattern structure  122  to be formed on the sidewall  124  or the outer surface S 3 , for example, the thermoplastic carrier  12  only forms the pattern structure  122  on the sidewall  124  corresponding to the left molar, right molar or both molars of the user, so that the dental carrier  1  becomes a kind of dental carrier to coat the medicament on the molars of the user. 
         [0046]    In an embodiment of the present invention, the user can also use the dental carrier  1  through putting the dental carrier  1  into the mouth without coating the medicament, for example, during intense exercise including various ball games and boxing, various fighting techniques, close combat, integrated fighting techniques training and competition, the user can wear the present invention as a mouth guard. Otherwise, the dental carrier  1  of the present invention is used as a bite plate to treat bruxism or tempromandibular joint related problems. Otherwise, the dental carrier  1  of the present invention is used as a periodontal dressing after periodontal surgery. Otherwise, the dental carrier  1  of the present invention is used as a dental retainer after orthodontic treatment. 
         [0047]    As shown in  FIGS. 2  (A) to  3  (C), in a better embodiment of the present invention, the gaps between the edges of each cavity of the cavity structure  1221  and the edges of each trench of the lateral trench structure  1222  and the longitudinal trench structure  1223  are less than 5 mm, preferably less than 3 mm. The depth of each cavity of the cavity structure  1221  and each trench of the lateral trench structure  1222  and the longitudinal trench structure  1223  into the sidewall  124  are at least 0.1 mm preferably. 
         [0048]    Please refer to  FIG. 4  and  FIG. 5 .  FIG. 4  shows a cross-section diagram crossing along to the I-I line in  FIG. 2A  of the thermoplastic carrier.  FIG. 5  shows a schematic diagram of the thermoplastic carrier in another embodiment of the present invention. The dental carrier  1  of the present invention is designed so that the width of the thermoplastic carrier  12  is uniform, as shown in  FIG. 4 . However, in order to allow the thermoplastic carrier  12  to be adapted more closely to the teeth, root or periodontal tissue of the user, another design of the present invention is to let the inner and outer sidewalls  124  of the thermoplastic carrier  12  are inclined toward each other, as shown in  FIG. 5 . The thermoplastic carrier  12  further comprises a convex structure  126 , and the convex structure  126  is configured on the upper half of the sidewall  124  and comprises a convex structure groove  1261 , as shown in  FIG. 4  and  FIG. 5 . 
         [0049]    Wherein, in the embodiments of  FIG. 4  and  FIG. 5 , the convex structure  126  extends in mutual direction towards each another, but the user or the manufacturer can also extend the convex structure  126  in the direction of the sidewall  124  of the thermoplastic carrier  12 , in such cases, the direction of arrangement of the convex structure groove  1261  is in the same direction as the pattern structure  122 . The convex structure groove  1261  has the same effect as the patterned structure  122 , and the convex structure groove  1261  is adapted to apply the medicament in the convex structure groove  1261 , so that the medicament can contact with the root or periodontal tissue of the user to be coated on the root or periodontal tissue. 
         [0050]    Please refer to  FIG. 6  (A) to (C).  FIG. 6  (A) to (C) shows a schematic diagram of the dental carrier respectively in another embodiment of the present invention. The present invention further provides another dental carrier  2 , and the dental carrier  2  comprises a thermoplastic carrier  22 , and the thermoplastic carrier  22  comprises a surface S 4 , wherein the surface S 4  has a pattern structure  222 . 
         [0051]    Wherein, the pattern structure  222  comprises three embodiments: the cavity structure  2221 , the lateral trench structure  2222  and the longitudinal trench structure  2223 , as shown in  FIG. 6  (A) to (C) respectively. However, the present invention is not limited to it, in addition to the lateral trench structure  2222  and the longitudinal trench structure  2223 , the trench structure can also comprise an oblique trench structure, a helical trench structure, and a serrated trench structure. 
         [0052]    Wherein, before using the present invention, the thermoplastic carrier  22  needs to be heated, for example, the thermoplastic carrier  22  is heated and softened in the hot water, and the thermoplastic carrier  22  is taken out, after the surface of the thermoplastic carrier  12  is slightly cooled, a user will put the dental carrier  2  into the mouth to be bent according to the shapes of dentition of the user, so that the thermoplastic carrier  22  can be impressed on the surface of the teeth or the alveolar ridge to be shaped, and the surface S 4  of the thermoplastic carrier  22  having the pattern structure  222  needs to be oriented towards the teeth of the user, with respect to the relative position, the surface S 4  having the pattern structure  222  is similar to the inner surface S 1  of the thermoplastic carrier  12  of the dental carrier  1  in function. 
         [0053]    Please refer to  FIG. 6  and  FIG. 7  at the same time.  FIG. 7  (A) to (C) shows a cross-section diagram crossing along to the II-II line in  FIG. 6A  of other exterior of the dental carrier in another embodiment of the present invention. As shown in  FIG. 6  (A) to (C), the exterior of the thermoplastic carrier  22  is an elongated shape and the cross-sectional shape of the elongated shape is circular, but the present invention is not limited to it, the cross-sectional shape of the elongated thermoplastic carrier  22  also comprises an elliptical shape and a rectangular shape, as shown in  FIG. 7  (A) to (C). 
         [0054]    The purpose of the pre-use work mentioned above is to allow the thermoplastic carrier  22  to be formed in the shape of the teeth or the alveolar ridge of the user to achieve the customization effect of the present invention. 
         [0055]    Next, fill the inner surface S 4  comprising the pattern structure  222  with a medicament to be applied to the teeth, root, alveolar ridge or periodontal tissue to allow the user to directly impress the present invention, so that the teeth, root, alveolar ridge or periodontal tissue can contact with the inner surface S 4  comprising the pattern structure  222 , and the medicament can be uniformly applied to the teeth, root, alveolar ridge or periodontal tissue of the user. Wherein, the medicament comprises a whitening medicament, a mouthwash, and a medicament for the treatment or maintenance of teeth, root, alveolar ridge or periodontal tissue. 
         [0056]    The above-mentioned pattern structure  222  has the function of storing the medicament and leading the medicament to the area to be treated such as teeth, root or periodontal tissue. In the practical application, the user can only apply the medicament on the partial pattern structure  222  to treat the partial position of the teeth, root or periodontal tissue of the user. However, the pattern structure  222  of the present invention is not necessary to be covered the surface S 4  all over, and the design of the present invention also allows the pattern structure  222  to be formed on the surface S 4 , for example, the thermoplastic carrier  22  only forms the pattern structure  222  on the surface S 4  corresponding to the left molar, right molar or both molars of the user, so that the dental carrier  2  becomes a kind of dental carrier to coat the medicament on the molars of the user.
