Abstract:
A healing collar for use with an endosseous dental implant that has an internal-threaded passage and at the top has a multi-sided male projection includes a cylindrical-shaped external surface, a first cavity at one end that has the same number of sides as the male projection atop the implant and a size and shape adapted to fit frictionally or non-frictionally over the male projection. At the other end of the healing collar is an opening leading to a second internal cavity having a plurality of sides adapted to engage a tool suitable for inserting an implant, joined to the healing collar, into a passage formed in the jawbone of a patient formed to receive the implant. Between the first and second internal cavities is an inwardly-projecting flange that has upper and lower annular surfaces for engaging the head a fixation screw, and the top surface of the implant, respectively.
