A Novel Method to Evaluate Precision of Optical Implant Impressions with Commercial Scan BodiesAn Experimental Approach

摘要

PurposeOptical transfer is realized with system-specific transfer posts (scan bodies) mounted on dental implants or on implant analogs. This study presents a novel algorithm for creation of geometry on the surface of dental implant scan bodies and examines the precision of the optical acquisition of scan bodies and the precision of the position of the screw-tightened scan bodies on dental implant analogs.
