Abstract:
A dental implant (100) comprises a solid elongated body including a longitudinal axis having distal and proximal ends in which the proximal end includes a collar (120) having an axial length in a range of about 1 to about in which the proximal segment includes a surface texture adapted for the promotion of osseo-integration of surrounding preferably cortical bone (14). Either one or the other of the sub-segments is provided with an ordered microgeometric repetitive surface pattern in the form 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 the microgeometric repetitive patterns define a guide for preferential promotion of the rate, orientation and direction of growth colonies of cells of the maxillofacial bone or tissue which is in contact with the surface pattern.
