Abstract
A dental implant includes a screw body and screw threads. The screw body has an apical end and a coronal end. Screw threads include a primary thread and a secondary thread, which overlap in at least a portion of the screw thread. Thread depth progressively increases from the coronal end to the apical end. The coronal end may contain any suitable secondary characteristics, such as machined threads, grooves, micro-threads, or any other characteristics favorable to successful outcomes with dental implant treatment. A method of making such a dental implant is also disclosed.
Claims15
A dental implant having an apical end and a coronal end, the dental implant comprising:
- a screw body;
- and
- at least one screw thread defining a root and a crest, the at least one screw thread comprising a primary thread configuration and a secondary thread configuration along at least a portion of the screw thread, the primary thread configuration and the secondary thread configuration overlapping on at least a portion of the screw thread such that along the overlapping portion of the screw thread the secondary thread configuration extends from the root to an intermediate position between the root and crest, and the primary thread configuration extends from the intermediate position to the crest;
- wherein the at least one screw thread becomes progressively deeper from the coronal end to the apical end.
A method of making a dental implant having an apical end and a coronal end, the method comprising:
- providing a cylindrical or conical feedstock;
- applying at least one first cut path to set a lower limit of a depth that increases from the coronal end to the apical end;
- and
- applying at least one second cut path along at least a portion of the first cut path to set an upper limit of the depth.
