Abstract

An implant system and a method of forming the implant system including an implant to be implanted into living bone. The implant includes titanium. The implant includes a first surface geometry on a first portion of a surface of the implant and a second surface geometry on a second portion of the surface of the implant. The first surface geometry includes at least a submicron topography including tube-like structures and the second surface geometry includes a first micro-scale topography, a second micro-scale topography superimposed on the first topography, and a submicron topography superimposed on the first and second micro-scale topographies, the submicron topography including the tube-like structures.

First claim

What is claimed is:

1 . A mating component configured to be coupled with an implant, the mating component comprising:
a post; a stem; and a transgingival portion, wherein the transgingival portion comprises at least one external surface including:
a micro-scale topography; and
a submicron topography superimposed on the micro-scale topography, wherein the submicron topography comprises tube structures.

2 . The mating component of claim 1 , wherein the tube structures have heights in a range of about 200 nanometers to about 400 nanometers.

3 . The mating component of claim 1 , wherein the tube structures have diameters in a range of about 10 to about 400 nanometers.

4 . The mating component of claim 1 , wherein the tube structures are formed from titanium dioxide.

5 . The mating component of claim 1 , wherein the micro-scale topography includes peak-to-valley heights of about 1 microns to about 30 microns.

6 . The mating component of claim 5 , wherein the micro-scale topography includes peak-to-valley heights of about 10 microns to about 20 microns.

7 . The mating component of claim 1 , wherein the micro-scale topography comprises a first micro-scale topography and a second micro-scale topography, wherein the first micro-scale topography includes peak-to-valley heights of about 1 microns to about 30 microns and wherein second micro-scale topography includes peak-to-valley heights of less than about 10 microns and peak-to-peak distances of less than about 3 microns.

8 . The mating component of claim 1 , further comprising:
a second micro-scale topography superimposed on the micro-scale topography, the second micro-scale topography being less coarse than the micro-scale topography; and a second submicron topography superimposed on the micro-scale topography and the second micro-scale topography, the second submicron topography including the tube structures.

9 . The mating component of claim 8 , further comprising a third micro-scale topography including peak-to-valley heights of less than about 10 microns and peak-to-peak distances of less than about 3 microns.

10 . The mating component of claim 1 , wherein at least one of the stem, post, and transgingival portion comprise titanium.

11 . The mating component of claim 1 , wherein at least one of the stem, post, and transgingival portion comprise a titanium alloy.

12 . The mating component of claim 1 , wherein at least one of the stem, post, and transgingival portion comprise titanium nitride.

13 . The mating component of claim 1 , wherein the transgingival portion is positioned between the stem and the post.

14 . The mating component of claim 1 , wherein at least one of the stem, post, and transgingival portion comprise a ceramic.

15 . The mating component of claim 1 , wherein at least one of the stem, post, and transgingival portion comprise a polymer.

16 . An implant system, comprising:
a dental implant; and a mating component configured to be coupled with the dental implant, the mating component comprising:
a post;
a stem; and
a transgingival portion, wherein the transgingival portion comprises at least one external surface including:
a micro-scale topography; and
a submicron topography superimposed on the micro-scale topography, wherein the submicron topography comprises tube structures.

17 . The implant system of claim 16 , wherein the dental implant comprises at least one of titanium and a titanium alloy.

18 . The implant system of claim 16 , wherein the dental implant comprises a micro-scale topography and a submicron topography superimposed on the micro-scale topography.

19 . The implant system of claim 16 , wherein the tube structures have heights in a range of about 200 nanometers to about 400 nanometers.

20 . The implant system of claim 16 , wherein the stem comprises a locking portion and a non-locking portion to interface with the dental implant and wherein the transgingival portion defines a vertical stop surface that is configured to engage a coronal end surface of the dental implant.
