Abstract
An improved dental endosteal implant is disclosed. The implant comprises a base and a core. The base is comprised of a bio-compatible material and has first and second ends and side walls which include serrations having substantially planar surfaces facing in the direction of the second end. The depth of the serrations nearest said second end is greater than the depth of the serrations nearest the first end. The core is configured so as to permit cooperative engagement with at least one prosthetic crown.
Claims32
A dental, prosthetic, endosteal implant comprising:
- a base comprised of a bio-compatible material, said base having first and second ends axially spaced along the longitudinal axis of said base and sidewalls which include serrations comprising alternating oblique and substantially planar surfaces, said substantially planar surfaces being substantially perpendicular to both the longitudinal axis of said base and the direction of the intended occlusal load and said oblique surfaces being disposed at an angle to the longitudinal axis of said base, the surface area of said planar surfaces nearest said second end being greater than the surface area of said planar surfaces nearest said first end, said first end being the outermost end upon implantation and said second end being the implanted end;
- and
- a core extending from the first end of said base and configured to permit cooperative engagement with at least one prosthetic crown.
In a dental, prosthetic, endosteal implant comprising:
- a base comprised of a bio-compatible material, said base having first and second ends axially spaced along the longitudinal axis of said base and side walls which include serrations comprising alternating oblique and substantially planar surfaces, said substantially planar surfaces being substantially perpendicular to both the longitudinal axis of said base and the direction of the intended occlusal load and said oblique surfaces being disposed at an angle to the longitudinal axis of said base, said first end being the outermost end upon implantation and said second end being the implanted end;
- the improvement wherein the surface area of the planar surfaces nearest said second end is greater than the surface area of the planar surfaces nearest said first end.
A dental, prosthetic, endosteal implant comprising:
- a base comprised of a bio-compatible material, said base having first and second ends axially spaced along the longitudinal axis of said base and side walls which include serrations comprising alternating oblique and substantially planar surfaces, said substantially planar surfaces being substantially perpendicular to both the longitudinal axis of said base and the direction of the intended occlusal load and said oblique surfaces being disposed at an angle to the longitudinal axis of said base, the surface area of said planar surfaces which, upon implantation, are adjacent to the aveolar crest being less than the surface area of said planar surfaces in the remaining portion of the base.
