摘要：A dental implant comprises a solid elongated body including a longitudinal axishaving distal and proximal ends in which the proximal end includes a collar having an axiallength in a range of about 1 to about 3 millimeters. The collar exhibits a proximal and a

distal segment in which the proximal segment includes a surface texture adapted for thepromotion of tissue growth and in which the distal segment includes a surface textureadapted for the promotion of osseo-integration of surrounding preferably cortical bone.Either one or the other of the sub-segments is provided with an ordered microgeometricrepetitive surface pattern in the form of alternating ridges and grooves, each having afixed or established width in a range of about 2.0 to about 25 microns and a fixed orestablished 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 tissuewhich is in contact with the surface pattern.
