Background: Computer-assisted implant surgery usually requires a radiographic scan template as the basis for prosthetic-driven implant planning and surgical guide fabrication.
Purpose: The study aims to evaluate the accuracy of image-fusion stereolithographic guides in which a computed tomography (CT) scan is mapped with three-dimensional optical scans of cast and diagnostic wax-up.
Materials And Methods: Three-dimensional error at the base and tip of the implants, angular deviation of the implant-axis, and the inserting-depth error of 120 implants with a length of 10 mm and a caliber of 4.
