Dental implant system with repeating microgeometric surface patterns

A dental implant system comprising an implant element for surgical insertion into a maxillofacial bone and tissue of a patient, said implant element having a collar section and a distal, anchor-like section, said anchor section having a first ordered microgeometric, repetitive surface pattern in a form of a multiplicity of alternating ridges and grooves, each having an established width in a range of about 2 to about 25 microns, and an established depth in a range of about 2 to about 25 microns, each groove having a base and a wall, each groove defining, in radial cross-section, a relationship of groove base to groove wall that is equal to, or less than, about ninety degrees,

• whereby said micro-geometric repetitive pattern defines a guide for a preferential promotion of the rate, orientation and direction of growth of colonies of cells of said maxillofacial bone or tissue, which are in contact with said surface pattern.
