Claims
- 1. A dental implant for insertion into an ostectomy site, and reducing potential for related bone loss thereat, the implant comprising:a solid elongate body having a longitudinal axis, said axis having a distal and a proximal end, said proximal end defining a collar having an axial length in a range of about 1 to about 3 millimeters, said collar further comprising a proximal segment and a distal segment in which said proximal segment comprises a surface texture for the promotion of tissue growth thereinto, and in which said distal segment comprises a surface texture for the promotion of bone growth thereinto, and further in which said distal segment defines an ordered microgeometric repetitive surface pattern in the form of a multiplicity of alternating ridges and grooves, each having a fixed or established width in a range of about 2.0 to about 25 microns and a fixed or established depth in a range of about 2.0 to about 25 microns, in which said microgemoetric repetitive patterns define a guide for preferential promotion of the rate, orientation and direction of growth colonies of cells of soft tissue of said osseotomy site which are in contact with said surface pattern.
- 2. The implant as recited in claim 1, in which said surface texture of said proximal segment comprises a surface texture selected from the group of surface treatments consisting essentially of:laser cutting, acid etching, photolithography, abrasion/roughening, plasma spraying, calcium sulfate, biocompatible glass, collagen, hydroxapatite, growth factor compounds, and combinations thereof.
- 3. The dental implant as recited in claim 2, in which a ratio of axial length of said proximal to said distal segments comprises a range of about 1:4 to about 4:1.
- 4. The dental implant as recited in claim 3, in which a proximal radial surface of said implant includes means for complemental securement with a dental abutment.
- 5. The dental implant as recited in claim 3, in which a proximal radial surface of said implant includes means for complemental securement with a dental abutment.
- 6. The dental implant as recited in claim 2, in which a ratio of axial length of said proximal to said distal segments comprises a range of about 1:4 to about 4:1.
- 7. The implant as recited in claim 1, in which said surface texture of said distal segment comprises a surface texture selected from the group of surface treatments consisting essentially of:laser cutting, acid etching, photolithography, abrasion/roughening, plasma spraying, calcium sulfate, bicompatible glass, collagen, hydroxyapatite, growth factor compounds, and combinations thereof.
- 8. A dental implant for insertion into an osseotomy site, and reducing potential for related bone loss threat, the implant comprising:a solid elongate body having a longitudinal axis, said axis having a distal and a proximal end, said proximal end defining a collar having an axial length in a range of about 1 to about 3 millimeters, said collar further comprising a proximal segment and a distal segment in which said proximal segment comprises a surface texture for the promotion of tissue growth thereinto, and in which said distal segment comprises a surface texture for the promotion of bone growth thereinto, and further in which said proximal segment defines an ordered microgeometric repetitive surface pattern in the form of a multiplicity of alternating ridges and grooves, each having a fixed or established width in a range of about 2.0 to about 25 microns and a fixed or established depth in a range of about 2.0 to about 25 microns, in which said microgemoetric repetitive patterns define a guide for preferential promotion of the rate, orientation and direction of growth colonies of cells of bone at said osseotomy site which are in contact with said surface pattern.
- 9. A dental implant for insertion into an osseotomy site, and reducing potential for related bone loss thereat, the implant comprising:a solid elongate body having a longitudinal axis, said axis having a distal and a proximal end, said proximal end defining a collar having an axial length in a range of about 1 to about 3 millimeters, said collar further comprising a proximal segment and a distal segment in which said proximal segment comprises a surface texture for the promotion of tissue growth thereinto, and in which said distal segment comprises a surface texture for the promotion of bone growth thereinto, in which said proximal and distal segments define respective ordered microgeometric repetitive surface patterns in the form of a multiplicity of alternating ridges and grooves, each having a fixed or established width in a range of about 2.0 to about 25 microns and a fixed or established depth in a range of about 2.0 to about 25 microns, in which said microgemoetric repetitive patterns define a guide for preferential promotion of the rate, orientation and direction of growth colonies of cells of bone and soft tissue at said ossseotomy site which are in contact with said respective surface patterns.
- 10. The system as recited in claim 9, in which a ratio of axial length of said proximal to said distal segments comprises a range of about 1:4 to about 4:1.
- 11. The system as recited in claim 10 in which a proximal radial surface of said implant includes means for complemental securement with a dental abutment.
