ABSTRACT

PURPOSE: This in vitro study analyzed the accuracy of a computer-assisted design (CAD)/computer-assisted manufacturing (CAM) guided implant surgery system by comparing linear, angular, and coronal deviations between the planned and final implant placement. METHODS: By using a fully guided surgery workflow, 32 dental implants were placed in 16 partially edentulous models. After virtual design of the restorations, radiological and CAD files were matched and implant positions were planned by using dedicated implant planning software (Galileo Implant version 1.9.2.). Templates were designed (Cerec Omnicam) and milled (Cerec MC XL) by using chairside workflow. Galileo Implant version 1.9.2. was used to evaluate accuracy. RESULTS: Mean horizontal and angular-coronal total deviation values were 0.2 mm (SD = 0.126) and 1.1º (SD = 0.834) respectively. Multivariate analysis of variance showed significant differences in horizontal and angular-coronal total deviation in the 32 implants (P = 0.0001). Multivariate analysis with one-factor interaction showed no statistical difference in implant position or implant type (P = 0.139) between eight maxilla models and eight jaw models. CONCLUSION: Horizontal and angular-coronal deviations of implants placed with chairside digital workflow were within the recommended safety margin for fully guided surgery.
