MAXILLOFACIAL SURGICAL ELEMENTS HAVING ORDERED MICROGEOMETRIC SURFACE PATTERNS

摘要

A dental implant system includes an implant element (46) for surgical insertion into a maxillofacial bone or tissue of a patient, the implant element having a collar section and a distal, anchor-like section, the collar section (50) having an ordered microgeometric repetitive surface pattern in the form of alternating ridges (12) and grooves (10), each having a fixed or established width in a range of about 2.0 to about 25 microns (micrometers) and a fixed or established depth in a range of about 2 to about 25 microns, in which the microgeometric repetitive patterns define a guide preferential promotion of the rate, orientation and direction of growth colonies of cells of the maxillofacial bone or tissue which are in contact with the surface pattern.
