S-1 - 3D Surgical Guide Design for Targeted Endodontic Microsurgery

Targeted Endodontic Microsurgery (TEMS) utilizes trephine burs and 3D-printed surgical guides to achieve osteotomy and root resection in a single step. The digital workflow for guide fabrication requires conversion of a patient’s physical anatomy into a virtual model upon which a TEMS guide is designed and then 3D-printed. This presentation will describe principles of surgical guide design to include patient factors, CBCT acquisition, ways to arrive at a digital model, and components of the guide. The digital workflow required for guide fabrication will be presented from start to finish utilizing implant planning software (Blue Sky Plan). The resultant digital guide will be ready for export in STL format for 3D printing. The presentation will conclude with a couple of unique surgical cases that benefited from the precision afforded by a precisely positioned and guided trephine.
