Prosthetically Driven Computer-Guided Implant Placement and Restoration Using CEREC: A Case Report

Abstract

Developments in 3-dimentional (3D) diagnostic technology and advanced digital optical imaging have improved the predictability, safety, and efficiency of restoratively driven implant dentistry. Surgical procedures may now be performed in a single visit utilizing chairside, computer-aided design/computer-aided manufacturing technology and in situations when a two-stage implant protocol is indicated as demonstrated in this case. The CEREC® GALILEOS® integration workflow system was used to prosthetically plan and place an implant in the lower right mandibular first molar site, No. 30, which had been previously grafted following tooth extraction. Preoperative planning was performed, taking into consideration all anatomic landmarks, current tissue status, and restorative needs while incorporating cone-beam computed tomography data to design and mill a stable, tooth-supported surgical guide (CEREC Guide 2.0). After placement and subsequent osseointegration, the implant was restored chairside in a pre-doctoral treatment center. The Sirona TiBase system and VITA ENAMIC® IS block were used to produce an esthetically pleasing and clinically excellent screw-retained implant crown.
