Abstract:
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.
