Abstract
A modified dental implant fixture designed to preserve lingual bone by having the coronal aspect of the implant being compatible with bony anatomy that is higher on the lingual side of the implant surgical site. The implant may be of either the single stage or the two stage design. By modifying the shape of the top of the implant fixture to mimic healing/healed bony anatomy, bone is preserved and bone growth is possibly encourage.
Claims35
A dental implant for implanting within a human jawbone, the jawbone having lingual and buccal sides, the implant comprising:
- a generally cylindrical longitudinal body having an outer surface, an apical end and a coronal end having an inner female conical shape;
- an abutment having a lower portion with an outer male conical shape for connection with the inner conical shape of the coronal end of said body;
- said body having a length defined between said ends on said outer surface;
- and
- said coronal end being contoured such that when positioned within the jawbone said length is greatest on the generally lingual side and least on the generally buccal side.
A dental implant for implanting within the human jawbone, the jawbone having lingual and buccal sides, the implant comprising:
- a generally cylindrical longitudinal body having an outer surface, an apical end and a coronal end having an inner conical shape;
- an abutment having a lower portion with an outer conical shape for connection with the inner conical shape of the coronal end of said body;
- said body having a bone engaging surface defined between said ends;
- and
- said coronal end being contoured such that when positioned within the jawbone said bone engaging surface is longest/greatest on the generally lingual side and shortest/least on the generally buccal side.
A dental implant for implanting within the human jawbone, the jawbone having lingual and buccal sides, the implant comprising:
- a generally cylindrical longitudinal body having an outer surface, an apical end and a coronal end having an inner conical shape;
- an abutment having a lower portion with an outer conical shape for connection with the inner conical shape of the coronal end of said body;
- said body having a bone engaging surface defined between said ends;
- said coronal end being contoured such that the bone engaging surface can be prepared to be longest/greatest on the generally lingual side and shortest/least on the generally buccal side when positioned within the jawbone;
- and
- said body also having a non-bone engaging surface extending coronally from said bone engaging surface whereby said non-bone engaging surface when combined with said bone engaging surface is longest/greatest on the lingual side and shortest/least on the generally buccal side.
A dental implant for implanting within the human jawbone, the jawbone having lingual and buccal sides, the implant comprising:
- a generally cylindrical longitudinal body having an outer surface, an apical end and a coronal end having an inner conical shape;
- an abutment having a lower portion with an outer conical shape for connection with the inner conical shape of the coronal end of said body;
- and
- said body having a bone engaging portion defined between said ends of a defined length, said coronal end of said bone engaging portion having a coronal facing generally asymmetric truncated cylindrical surface.
