Abstract
The subject matter of the invention is an apparatus for explanting a dental implant from a human or animal bone. In one example, the invention may use a trephine bur on the 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.
Claims16
An apparatus for explanting a dental implant from a human or animal bone, the apparatus comprising:
- a trephine bur;
- a bur bit on an end of the trephine bur;
- a guide pin attachable to the dental implant;
- and
- a guide element attached to the trephine bur, the guide element cooperating with the guide pin to guide the trephine bur in an axial direction of the guide pin to explant the dental implant, wherein the guide element is coaxially retained inside the trephine bur and the guide pin is coaxially retained with the trephine bur in the dental implant.
An apparatus for explanting a dental implant from a human or animal bone, the apparatus comprising:
- a trephine bur;
- a bur bit on an end of the trephine bur;
- a guide pin attachable to the dental implant;
- and
- a guide element attached to the trephine bur, the guide element cooperating with the guide pin to guide the trephine bur in an axial direction of the guide pin to explant the dental implant, wherein the guide element is disposed above the trephine bur.
An apparatus for explanting a dental implant from a human or animal bone, the apparatus comprising:
- a trephine bur;
- a bur bit on an end of the trephine bur;
- a guide pin attachable to the dental implant;
- and
- a guide element attached to the trephine bur, the guide element cooperating with the guide pin to guide the trephine bur in an axial direction of the guide pin to explant the dental implant, wherein the trephine bur is open at the top and the guide element is spaced from an interior wall of the trephine bur to feed material into the trephine bur or evacuate material from the trephine during the explanting of the dental implant.
An apparatus for explanting a dental implant from a human or animal bone, the apparatus comprising:
- a trephine bur;
- a bur bit on an end of the trephine bur;
- a guide pin attachable to the dental implant;
- a guide element attached to the trephine bur, the guide element cooperating with the guide pin to guide the trephine bur in an axial direction of the guide pin to explant the dental implant;
- and
- a plurality of webs to immovably couple the guide element to the trephine bur.
