METHOD AND APPARATUS FOR REPLICATING THE POSITION OF INTRA-OSSEOUS IMPLANTS AND ABUTMENTS RELATIVE TO ANALOGS THEREOF

摘要

The position of intra-osseous implants and abutments to analogs is enabled andenhanced by using the longitudinal axial locked position of a post (12a) of animplant (12) having a locking taper in a bore (10a) of an implant (10) havinga generally matching locking taper as a reference to determine the position ofa stop surface (14c) on impression posts, abutment analog posts and the likereceived in the bore of an implant and implant analog. In another embodimentthe bore (16) of an implant analog (16) is provided with a shelf (16c) locatedat a position determined by the axial distance of the locked position of theabutment post to prevent over-seating. Controlled retentive resistance andstability of a post is provided by using flats formed in the bore of animplant analog and by forming rings on a post receivable in the bore of animplant or implant analog. One such ring (18c) is formed with an outerperiphery sized and configured to allow bending of the outer peripheralportion in a direction opposite to the direction of insertion in a bore toprovide greater retentive resistance than insertion resistance.
