Adhesive residue on the CAD-CAM surgical guide sleeve: A technical report.

Computer-aided design and computer-aided manufacturing (CAD-CAM) surgical guides can be used by the clinician and dental technician to create a definitive cast before surgery, thereby allowing an indirect interim restoration to be fabricated. However, the accurate transfer of the interim restoration from the laboratory to the surgical site requires a precise interface between components. This article reports the prosthetic significance of adhesive residue on the intaglio surface of the CAD-CAM surgical guide sleeve, which can create errors in the implant analog position of the definitive cast. A technique for identifying the presence of residue and its careful removal are also introduced.
