In one example, the apparatus includes a trephine bur on an end side of which there is formed a bur bit. In one or more examples, an apparatus by which dental implants can be drilled out accurately is achieved by a guide pin that can be attached to the dental implant and by a guide element attached to the trephine bur, said guide element cooperating with the guide pin so that the trephine bur is guided in the axial direction of the guide pin.
Description
- This patent is a continuation of U.S. patent application Ser. No. 12/565,539, which was filed on Sep. 23, 2009 and claim priority to German Patent Application No. DE 10 2008 049 012.1, which was filed on Sep. 25, 2008, both of which are hereby incorporated by reference in their entireties.
- The present disclosure relates to dental implants and, more particularly, to apparatus for explanting a dental implant from a human or animal bone.
- To replace missing teeth, it belongs to prior art to implant into the jaw bone artificial dental implants made from titanium, ceramics or from another suited material. Sometimes however it is also necessary to remove again an existing dental implant such as when there is an inflammation or sleeping implant. In this case, the dental implant can be drilled out again, using a hollow bur such as a trephine bur the inner diameter of which is only slightly larger than the largest outer diameter of the dental implant. Then, this trephine bur is at first held onto the dental implant, relying on the visual judgment of the doctor, in such a manner that the trephine bur forms a surrounding grip, at least rudimentarily, around the upper part of the dental implant. During drilling, the trephine bur is then guided by the dental implant. However, sometimes, the drilling occurs slantwise so that, in some cases, the dental implant is even cut into pieces, which involves a complicated surgical intervention in order to remove the rests of the dental implant.

FIG. 11 a is a side view of the guide cylinder of the apparatus shown inFIG. 11 . -
FIG. 12 shows the apparatus shown inFIG. 11 upon completion of the drilling operation. - In the
FIGS. 1 through 4 there is shown a first example apparatus in accordance with the teachings of the present invention at different instants in time. This example apparatus incorporates a hollowcylindrical trephine bur 1 on the end side of which there is formed abur bit 2. Opposite the bur bit 2 abur receiving mount 3 is attached to thetrephine bur 1, said bur receiving mount serving to couple thetrephine bur 1 to a corresponding drive which has not been illustrated in closer detail herein. In the interior of the trephine bur 1 aguide element 5 is retained through fourwebs 4. Thisguide element 5 is configured to be hollow cylindrical and is disposed coaxially with respect to thetrephine bur 1. - A
dental implant 7 is implanted in thejaw bone 6 and aguide pin 8 is placed in thisdental implant 7. Theguide pin 8 is disposed coaxial with thedental implant 7, i.e., the virtual longitudinal axis of theguide pin 8 and the virtual longitudinal axis of thedental implant 7 are identical or substantially identical. - In one example, the distance A between the end side of the
trephine bur 1 and the lower end side of theguide element 5 is at least equal to the length of thedental implant 7 whilst theguide pin 8 is considerably longer than the distance A so that theguide pin 8 already extends into theguide element 5 whilst thetrephine bur 1 still fits against thejaw bone 6. - In another example that has not been illustrated herein, the distance A substantially corresponds to the length of the
dental implant 7. - One example way in which such a drilling operation is performed will be described in detail herein after.
- At first, the
guide pin 8 is placed into the dental implant 7 (FIG. 1 ) so that theguide pin 8 is disposed coaxial, or substantially coaxial, with thedental implant 7. Then, thetrephine bur 1, with theguide element 5 disposed coaxially therein, is guided over theguide pin 8 so that theguide pin 8 enters into the interior of the guide element 5 (FIG. 2 ). Thanks to the cooperation betweenguide pin 8 andguide element 5, thetrephine drill 1 is oriented coaxial with thedental implant 7. If drilling is now performed, thetrephine bur 1 is reliably guided coaxial with thedental implant 7 thanks to the cooperation betweenguide pin 8 and guide element 5 (FIG. 3 ). Upon completion of the drilling operation, thetrephine bur 1 is removed from thejaw bone 6. At last, thedental implant 7 is removed, the bone on the end side of thedental implant 7 having to be detached first. In the first example shown in theFIGS. 1 through 4 , the clear diameter of thebur 1 is approximately 1 millimeters (mm) to 6 mm, in one example preferably 3 mm larger than the largest outer diameter of thedental implant 7. As a result, thedental implant 7 can be removed together with thebone substance 6 surrounding the implant. Such adental implant 7 can then be implanted somewhere else, for example at a place with but little bone substance. - The second example shown in the
FIGS. 5 through 8 differs from the first example by the fact that here the diameter of thetrephine bur 11 is but slightly larger than the largest outer diameter of the dental implant. As a result, the dental implant can be drilled out accurately, meaning with a minimum of bone matter. Such atrephine bur 11 is typically chosen when the implant is not intended for further use. - In the
FIGS. 9 through 10 , there is shown a third example. According to the third example, animplant 27 is embedded in ajaw bone 26, aguide pin 28 being placed into theimplant 27. Above thetrephine bur 21 there is mounted a hollowcylindrical guide element 25 which is retained on thetrephine bur 21 through fourwebs 24. Thistrephine bur 21 also has abur bit 22 on its end side. - Unlike the first example shown in the
FIGS. 1 through 4 , theguide element 25 is here disposed outside of thetrephine bur 21, but is also configured to be hollow cylindrical for reception of theguide pin 28. For the rest of the description, this third example substantially corresponds to the first example, which is shown in theFIGS. 1 through 4 . - In the fourth example shown in the
FIGS. 11 through 12 , and unlike in the first three examples, a commerciallyavailable trephine bur 32 is used, which is driven through abur reception mount 33 and also has abur bit 32. In this example, aguide cylinder 35, which can be placed into theimplant 37, is utilized instead of the guide pin. Thisguide cylinder 35 can be fixed in theimplant 37 through a receiving portion, here a thread. - Above the
implant 37, twoguide surfaces guide cylinder 35. In the region of theseguide surfaces guide cylinder 35 is configured to be cylindrical whilst theguide cylinder 35 comprises, in the region between theguide surfaces groove 40 so that theguide surfaces groove 40. In the region of theguide surfaces guide element 35 substantially corresponds to the clear inner diameter of thetrephine bur 31 so that theguide cylinder 35 can be introduced into thetrephine bur 31, guiding said bur coaxial with theimplant 37 during the drilling operation. - If the physician uses a trephine bur and a guide cylinder the diameters of which correspond to the diameter of the implant, the implant is drilled out without bone substance. If, by contrast, it uses a trephine bur and a guide cylinder whose diameter is larger than the implant, bone substance is drilled out, together with the implant, and said bone substance can be implanted again somewhere else.
- Each implant manufacturer gives the receptacle for its implant an individual shape. It may be, as shown herein, a thread, but it may also be of another shape. It is understood that the fastening means of the guide pin or of the guide cylinder is configured according to the receptacle of the implant and needs not be a thread like in these examples.
- In another example that has not been illustrated herein, the trephine drill may be equipped with an ultrasonic cutting apparatus or with a piezo cutting apparatus.
- In view of the foregoing, the examples described herein may provide an apparatus of the type mentioned herein above by means of which dental implants can be drilled out in an axially parallel manner. The inventions, as defined by the claims appended hereto, provide a technical solution to facilitate the results achieved by the examples.
- One or more of the foregoing examples are advantageous in that, through the cooperation of guide pin and guide element or of guide cylinder and trephine bur, one realizes a reliable guidance of the trephine bur so that said bur can penetrate into the bone, guided so as to be coaxial with the dental implant. One thus achieves that the dental implant is not damaged and can be readily and completely removed.
- Another advantage realized by one or more of the foregoing examples is that, by drilling around the implant in an axially parallel manner, one also burs out a certain amount of bone substance, the bone substance about the implant being of uniform thickness. Depending on the size of the trephine bur, the belt of bone substance around the implant can be more or less thick.
- In a preferred example, the guide element is configured to be hollow cylindrical, the clear width of the guide element being chosen to correspond to the diameter of the guide pin. The advantage thereof is that the guide element attached to the trephine bur receives the guide pin attached to the dental implant in order to thus realize a reliable guidance of the trephine bur. It is understood that the clear width of the guide element is configured to be so much larger than the diameter of the guide pin that the guide pin can be introduced readily into the guide element whilst concurrently the clear width of the guide element will not be chosen to be much larger than the diameter of the guide pin so that the guide pin can be guided in the guide element with only a small clearance. This applies in analogous fashion for the guide cylinder and the trephine bur.
- It has proved advantageous to, in some examples, coaxially attach the guide element to the trephine bur and to also coaxially attach the guide pin in the dental implant. One thus achieves that the trephine bur is guided coaxial with the dental implant so that the distance between the dental implant and the interior of the trephine bur is approximately equal over the circumference of the dental implant.
- In a preferred example the guide element is retained on the trephine bur through three to eight, preferably through four webs. Thanks to these webs, the trephine bur is open toward the top so that material possibly needed during the intervention may be fed or other material may be evacuated as a result thereof.
- In another preferred example, the guide pin already extends into the guide element when the trephine bur still fits against the bone. This offers the advantage that a guide of the trephine bur is already coaxial with the dental implant before the actual drilling begins so that it is no longer necessary to correct the orientation during the drilling operation.
- In still another preferred example, the guide element is spaced a distance from the bur bit that is equal to the length of the dental implant. The advantage thereof is that the trephine bur can penetrate so far into the bone until it reaches the lower end of the dental implant so that the dental implant can be completely drilled out.
- In another preferred example, the guide element is integral with the trephine bur, which contributes to simplify the manufacturing of the trephine bur.
- In another, particularly preferred example, a guide cylinder is used instead of the guide pin, the outer diameter of said guide cylinder corresponding to the clear inner diameter of the trephine bur. This offers the advantage that a commercially available trephine bur can be used while still achieving a coaxial guidance of the trephine bur.
- In an advantageous developed implementation, preferably two (at least one however) guide surfaces are formed on the circumference of the guide cylinder, said guide surfaces serving to bring the guide cylinder to abut in the interior of the trephine bur and to guide it. These guide surfaces are spaced apart in order to avoid canting.

- Further advantages of the example apparatus constructed in accordance with the invention described herein will become apparent in the appended drawings and the foregoing description of examples thereof Likewise, the invention lies in each and every novel feature or combination of features mentioned above or described herein after. The examples provided are not intended to limit the scope of the invention in any manner.
