Effects of minute misregistrations of prefabricated markers for image-guided dental implant surgery: an analytical evaluation.

Objectives: The goal of the present study was to develop a theoretical analysis of errors in implant position, which can occur owing to minute registration errors of a reference marker in a cone beam computed tomography volume when inserting an implant with a surgical stent.

Material And Methods: A virtual dental-arch model was created using anatomic data derived from the literature. Basic trigonometry was used to compute effects of defined minute registration errors of only voxel size.
