## Background
FIELD OF THE INVENTION
The present invention relates to a device, more particularly a dental cylindered pin, for enabling easy and simple positioning of a dental implant, kit comprising said device, and method of use.
BACKGROUND OF THE INVENTION
Dental implants have become popular in recent years as a way to provide permanent artificial teeth to patients that lost some or all of their teeth. Implant dentistry involves the restoration of one or more teeth in a patient's mouth using artificial components, such as dental implants and a prosthetic tooth and/or an abutment that is secured to the dental implant: the dentist drills into the patient's jaw bone and implants an artificial tooth root, i.e., a dental implant. Then, natural bone, by a process called osseointegration, fuses with this implant. An artificial crown can then be placed onto the implant.
Due to the hazards of improper drilling, computerized surgical guides have become a reliable method for performing implant surgery. This guides use computerized tomography and three-dimensional (3D) materials fabrication technology (e.g., computer controlled steriolithography, computer numerical control (CNC) machining, and the like) to create a custom implant drilling guide. This way, the guide provides control of the buco-lingual, mesial-distal and vertical placement of the surgical drills. Following the drilling process, there is often a need to further remove bone excess around the implant socket. This bone removal can be done by manually removing the bone excess after drilling according to rough estimation; creating another computerized reduction guide prior to the implant drilling guide; or removing the bone excess after screwing the implant into place.
However, each way has its disadvantages. For instance, manually removing the bone excess after drilling according to rough estimation is highly risky, due to the risk of excessive, undesired bone removal; creating another computerized reduction guide prior to the implant drilling guide requires the production of an additional computerized surgical guide just for the bone removal step, which dramatically increases the cost of the treatment and prolongs the overall duration of the procedure (i.e., by removing the first guide and placing the second one); and removing the bone excess after screwing the implant into place, particularly in the surrounding of the implant, might damage the neck surface of the implant.
Therefore, there is an unmet need for developing new, simple and cost efficient ways for removal of excess jaw-bone around an implant socket.

DETAILED DESCRIPTION OF THE INVENTION
The present invention provides a simple and safe way for removing excess jaw bone at a dental implant socket without the risk of damaging the dental implant or excessive and undesired bone removal. More particularly, the present invention provides means for assisting in performing the removal of excess jaw-bone around a dental implant prior the placement of the implant in its drilled socket, while maintaining a precise control of the vertical position of the implant as originally planned without damaging the implant surface. Specifically, the invention provides a dental pin 100 as defined above, i.e., a dental cylindered pin for controlling the amount of jaw-bone to be removed prior to placement of a dental implant into a drilled implant socket, wherein said dental cylindered pin 100 has an outer diameter of about 2.0 mm to about 4.5 mm and a length of about 3.5 mm to about 18 mm.
The dental cylindered pins 100 of the present invention may have various lengths and diameters, depending on the implant system being used. For instance, the dental cylindered pin 100 of the invention would have an external diameter that is smaller than that of the final drill being used, e.g., about 0.10, 0.15, 0.20, 0.25 mm, or more, smaller than the diameter of said final drill, for smooth insertion of said pin 100 into the drilled dental socket, and length that is identical to that of the dental implant to be used. For example, when the diameter of the final drill is 3.2 mm, the chosen dental cylindered pin 100 will have a diameter that is smaller than 3.2 mm, e.g., of about 3 mm.
In certain embodiments, the dental cylindered pin 100 of the invention has an external diameter in a range of about 2.0 mm to about 4.5 mm. In particular embodiments, the external diameter of the dental cylindered pin 100 of the invention is about 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, or 4.5 mm. It should be understood that the diameter of the dental pin 100 may also be smaller or bigger, depending on the final drill being used when preparing the dental implant socket, and preferably at least about 0.1, 0.15 or 0.2 smaller that the diameter of said final drill. More particularly, such dental cylindered pins 100 have an external diameter of about 2.6, 3.0, 3.6, or 4.2 mm.
In certain embodiments, the dental cylindered pin 100 of the invention has a length that is identical to that of the dental implant being used, i.e., any length in the range of about 3.5 mm to about 18 mm. For instance, the length of the dental cylindered pin may be about 3.5, 3.75, 4.0, 4.25, 4.5, 4.75, 5.0, 5.25, 5.5, 5.75, 6.0, 6.25, 6.5, 6.75, 7.0, 7.25, 7.5, 7.75, 8.0, 8.25, 8.5, 8.75, 9.0, 9.25, 9.5, 9.75, 10.0, 10.25, 10.5, 10.75, 11.0, 11.25, 11.5, 11.75, 12.0, 12.25, 12.5, 12.75, 13.0, 13.25, 13.5, 13.75, 14.0, 14.25, 14.5, 14.75, 15.0, 15.25, 15.5, 15.75, 16.0, 16.25, 16.5, 16.75, 17.0, 17.25, 17.5, 17.75 or 18.0 mm. It should be understood that the length of the dental pin may also be longer or shorter, depending on the length of the dental implant being used.
The dental cylindered pin 100 of the invention may be made of any suitable material, more particularly any suitable rigid material which enables easy insertion of the pin into a dental implant socket, and is preferably made of a medical graded material. The term “medical graded material” as used herein refers to any biocompatible rigid material which can be cleaned and sanitized by any suitable procedure/technique, and is preferably durable to jaw-bone drilling thus would not be easily damaged during bone site preparation, i.e., while removing excess jaw-bone around the dental implant socket prior to implantation. In certain embodiments, the dental cylindered pin 100 of the invention is made of a stainless steel, e.g., stainless steel 304, 304L, 316 or 316L. In other embodiments, the dental cylindered pin 100 of the invention is made of titanium or a titanium alloy, preferably those that are biocompatible such as Ti-6Al-7Nb and nickel-titanium (nitinol). In other embodiments, the dental cylindered pin 100 of the invention is made of any suitable carbon composite, or other suitable composites such as amalgam
After sterilization, the dental cylindered pin of the invention can be contained in sealed packaging until use.
The dental cylindered pin 100 of the invention may be either hollow, or solid, i.e., not a hollow cylinder.
In certain embodiments, the dental cylindered pin 100 of the invention is a hollow cylinder (FIGS. 1A and 1B). Such a dental cylinder pin 100 may have in its interior wall a tapping tapped or a screw-like engraving 104 for enabling the easy attachment and release of an insertion/removal apparatus 300 designed for insertion/removal of the dental cylindered pin 100 into/from an implant socket by attaching-to and detaching-from said dental cylindered pin 100. In particular, hollow dental cylindered pins 100 having a screw-like engraving 104 in the interior wall, said screw-like engraving may either be engraved through the entire inner side (FIG. 1B) or only near both edges of the pin (FIG. 1F). It should be understood that hollow dental cylindered pins 100 (no matter whether having a tapping tapped or a screw-like engraving in the interior wall) having different external diameters may still, and preferably, have an identical internal diameter so as to match, i.e., be compatible with, a particular insertion/removal apparatus 300.
In alternative configurations, the dental cylindered pin 100 may have at one or both of its planes a special groove 105 (FIGS. 1G and 1H) designed for enabling the attachment of a special insertion/removal apparatus 300 (FIGS. 4B and 4C); or is completely solid (FIGS. 1C and 1D), wherein the insertion/removal apparatus 300 may use vacuum or magnetic force for attaching to the pin.
In certain embodiments, the dental cylindered pin 100 of the invention has a lifting groove 105 at one or both of its ends. The term “lifting groove” as used herein refers to any structure or configuration, such as a cavity, rail, channel, recess, ledge or depression, or an area surrounded by protruding ridges, which enables the insertion of adjusted protrusions 305 at the tip of the insertion/removal apparatus 300 and interlocking therebetween (FIGS. 4B and 4C). A lifting groove as referred to herein may alternatively be located at the tip of the insertion/removal apparatus, whereas the adjusted protrusions are located at one or both of the pin's planes/ends.
In another aspect, the present invention provides a dental kit comprising: (i) at least one dental cylindered pin 100, each independently as defined herein; and (ii) an insertion/removal apparatus 300 for inserting/removing said at least one dental cylindered pin 100 into/from an implant socket.
In certain embodiments, for the sake of order and ease of use, various dental cylindered pins 100 of either identical or different lengths and/or diameters are stored in a special container 200,201, separated according to their length and/or diameter. Optionally, a separate container is used for storing dental cylindered pins of identical diameters and different lengths. Alternatively, the container 200,201 may hold any number of dental cylindered pins 100 of any diameter and length.
Accordingly, in certain embodiments, the dental kit of the present invention further comprises a designated container having a body 200,201 and a lid 210,211, for holding said at least one dental cylindered pin 100 and optionally said insertion/removal apparatus 300 (FIGS. 4D and 4E). The container 200,201 holding said at least one dental cylindered pin 100 and optionally said insertion/removal apparatus 300 may be made of any suitable material, but it is preferably made of a material that is suitable for medical use and can be sterilized using a standard sterilization method. Particular such containers are made of medical graded materials such as, without being limited to, stainless steel, titanium, titanium alloys, plastic, and polycarbonates.
In certain embodiments, such designated container 200,201 comprises cavities 202,203 suited for holding said at least one dental cylindered pin 100 and optionally said insertion/removal apparatus 300. For instance, such a container 200,201 may comprise 6 rows of 6 cavities, wherein each row is designed to hold 6 separate identical dental cylindered pins, and the difference between the rows is the length of the pins therein. In certain embodiments, the depth of each cavity 202 in said container 200 is constructed to align the upper surface of all the pins therein (FIGS. 2A-2C). Alternatively, all the cavities 203 in the container 201 have the same depth so that the pins 100 therein protrude according to their length (FIGS. 3A-3C). In such a case, the container's lid 211 is designed accordingly (FIGS. 3D-3F).
In certain embodiments, each dental pin 100 of the invention is engraved with its diameter and/or length, or with a marking indicating its diameter and length. In other embodiments, the container 200,201 has markings and/or engravings indicating the length and diameter of the different dental cylindered pins 100 it holds. In certain embodiments, the container 200 has designated cavities or holes 202, each designed to fit a specific dental cylindered pin 100 with a specific diameter and length. In such a case, when the container 200 holds all the dental pins 100, the upper surface of all of said pins 100 is aligned (FIG. 2). In other embodiments, the cavities or holes 203 in the container 201 are identical and designed to fit dental cylindered pins 100 with a specific diameter (FIG. 3). In such a case, when the container 201 holds all the dental cylindered pins 100, the upper surface of all of said pins is not aligned, and each pin protrudes according to its length.
In certain embodiments, the dental kit of the present invention comprises a plurality of dental cylindered pins 100 each independently as defined above, wherein each one of said dental cylindered pins 100 has a particular combination of an outer diameter in a range of about 2.0 mm to about 4.5 mm, and length in a range of about 3.5 mm to about 18 mm.
In certain embodiments, the dental kit of the invention comprises more than one, i.e., two, three, four, five or more, dental cylindered pins 100 having identical diameter and different lengths. Particular such dental kits include one or more, i.e., one, two, three or more, sets of dental cylindered pins 100 having identical diameter and different lengths, wherein each one of said sets consists of two or more, i.e., two, three, four or more, dental cylindered pins 100 having identical diameter and different lengths. In more particular embodiments, the dental kit of the invention comprises at least one set of three or more dental cylindered pins 100 having identical diameter and different lengths.
In certain embodiments, the dental kit of the invention comprises more than one, i.e., two, three, four, five or more, dental cylindered pins 100 having identical lengths and different diameters. Particular such dental kits include one or more, i.e., one, two, three or more, sets of dental cylindered pins 100 having identical length and different diameters, wherein each one of said sets consists of two or more, i.e., two, three, four or more, dental cylindered pins 100 having identical length and different diameters. In more particular embodiments, the dental kit of the invention comprises at least one set of three or more dental cylindered pins 100 having identical length and different diameters.
In certain embodiments, the dental kit of the invention comprises more than one, i.e., two, three, four, five or more, dental cylindered pins 100 having identical length and different diameters; and more than one, i.e., two, three, four, five or more, dental cylindered pins 100 having identical diameter and different lengths. Particular such dental kits include one or more, i.e., one, two, three or more, sets of dental cylindered pins 100 having identical length and different diameters, wherein each one of said sets consists of two or more, i.e., two, three, four or more, dental cylindered pins 100 having identical length and different diameters; and one or more, i.e., one, two, three or more, sets of dental cylindered pins 100 having identical diameter and different lengths, wherein each one of said sets consists of two or more, i.e., two, three, four or more, dental cylindered pins 100 having identical diameter and different lengths. In more particular embodiments, the dental kit of the invention comprises at least one set of three or more dental cylindered pins 100 having identical length and different diameters, as well as at least one set of three or more dental cylindered pins 100 having identical diameter and different lengths.
The insertion/removal apparatus 300 comprised within the dental kit of the present invention is designed for insertion/removal of a dental cylindered pin 100 as defined above into/from an implant socket, by attaching-to and detaching-from said dental cylindered pin 100. Accordingly, in order to insert a dental cylindered pin 100 according to the invention into a drilled dental socket, said pin should first be attached to the tip of an insertion/removal apparatus 300, wherein upon insertion into the dental socket, the insertion/removal apparatus 300 is easily detached, i.e., removed, from the dental pin 100. After removal of excess jaw-bone at the dental socket area, the insertion/removal apparatus 300 is re-attached to the inserted dental pin 100 and the pin is then easily removed out of the dental socket. After use, both the dental pin(s) 100 used as well as the insertion/removal apparatus 300 are cleaned and optionally sterilized for re-use.
In a further aspect, the present invention relates to a method for the safe removal of excess jaw-bone around a drilled implant socket, thereby adapting the depth of said implant socket to the length of a dental implant without the risk of excess removal of jaw-bone or damaging said dental implant, said method comprising the steps of: (i) selecting a suitable dental cylindered pin 100 as defined above according to the diameter of the drilled implant socket and the length of the dental implant for insertion into said implant socket, wherein the length of said dental cylindered pin 100 is identical to the length of the dental implant; (ii) optionally, attaching the selected dental cylindered pin 100 to an insertion/removal apparatus 300; (iii) placing said dental cylindered pin 100 in the drilled implant socket; (iv) performing excess jaw-bone removal around and up to the upper surface of said dental cylindered pin, thereby adapting the depth of the drilled implant socket to the length of the dental implant; (v) attaching said insertion/removal apparatus 300 to the dental cylindered pin 100; and (vi) removing the dental cylindered pin 100 from the depth-adapted implant socket. It should be noted that the diameter of the drilled dental socket may vary and is dependent on the drill used by the dentist/surgeon according to personal preference and/or limitations of the drilling location and bone condition and structure.
It should further be noted that although it would be easier to place the pins 100 of the invention by the aid of the insertion/removal apparatus 300, a skilled dentist/surgeon might be able to place such a pin in a dental implant socket manually, i.e., without the need of the insertion/removal apparatus 300 of the invention.
In certain embodiments, the attachment of said insertion/removal apparatus 300 to the dental cylindered pin 100 of the invention in steps (ii) and (v) of said method is performed by any suitable means, e.g., by a magnet or bulges 305 in said apparatus that interlock into a dedicated lifting groove 105 in the dental cylindered pin 100, or vise-versa, or by screwing 304 (FIG. 4A) said apparatus into a screw-like engraving 104 in said pin.
The method of the present invention enables removing excess jaw bone around a drilled dental implant socket, without the risk of excessive bone removal or damaging the dental implant, by utilizing a dental cylindered pin 100 having selected outer diameter and length, which is inserted into the dental implant socket, optionally by a dedicated insertion/removal apparatus 300, and assists in performing precise removal of the excess jaw-bone around the implant socket prior to the placement of an implant in said implant socket.
Thus, after drilling the dental implant socket, the dentist/surgeon selects a suitable dental cylindered pin 100 as defined above according to the diameter of the last drill used in drilling the implant socket and the length of the dental implant for placing into the implant socket. The dental cylindered pin 100 may be selected from a plurality of such pins contained within a dental kit as defined above, and is then optionally attached to the insertion/removal apparatus 300 and inserted into the dental implant socket. Once the dental pin 100 is located in the dental socket, the insertion/removal apparatus 300, if used for insertion of the dental cylindered pin, is detached from the pin, and the dentist/surgeon may continue performing the excess jaw-bone removal using any of the surgical techniques available. Once the excess jaw-bone around the neck of the dental cylindered pin 100 is removed, the insertion/removal apparatus 300 is attached to the pin and the pin is easily and smoothly removed, i.e., taken out, from the dental implant socket.
After performing the above steps, the jaw-bone level around the dental socket is at the precise depth of the dental implant for placing into the dental socket, and so the dental implant can be screwed into the dental socket until the dental implant's upper surface reaches the crestal bone level of the dental socket.
Unless otherwise indicated, all numbers used in this specification, expressing diameters or lengths of the dental cylindered pins defined above and used according to the method of the present invention, are to be understood as being modified in all instances by the term “about”. Accordingly, unless indicated to the contrary, the numerical parameters set forth in this specification are approximations that may vary by up to plus or minus 10% depending upon the desired properties to be obtained by the present invention.
