DENTAL IMPLANT HAVING A DUAL BIO-AFFINITY COLLAR

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 3 millimeters. The collar exhibits a proximal (26) and a distal segment (28) i...

Beschreibung
Zusammenfassung:	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 3 millimeters. The collar exhibits a proximal (26) and a distal segment (28) 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. La présente invention concerne un implant dentaire comprenant un corps allongé solide présentant un axe longitudinal ayant des extrémités distale et proximale, l'extrémité proximale comprenant un collier ayant une longueur axiale valant d'environ 1 à environ 3 millimètres. Le collier présente un segment proximal et un segment distal, le segment proximal ayant une texture de surface conçue pour favoriser la croissance tissulaire, et le segment distal ayant une texture de surface conçue pour favoriser l'osséo-intégration de l'os de préférence cortical périphérique. L'un ou l'autre des segments comprend un motif de surface répétitif microgéométrique ordonné se présentant sous la forme de nervures et de rainures ayant chacune une largeur fixe ou établie valant d'environ 2,0 à environ 25 microns, et une profondeur fixe ou établie valant d'environ 2,0 à environ 25 microns. Selon l'invention, les motifs répétitifs microgéométriques définissent un système de guidage favorisant de manière préférentielle la vitesse, l'orientation et la direction de la croissance de colonies de cellules de l'os ou du tissu maxillo-facial qui est en contact avec le motif de surface.
