Purpose: Computer-aided design/computer assisted manufacture (CAD/CAM) guides for surgery are finding widespread use as a tool for implant dentistry. This study sought to evaluate the accuracy and the precision of stereolithographic guide surgery system. Materials and Methods: Twenty epoxy resin mandibles with artificial silicone gum were fabricated, and each was fitted with an individual computed tomography (CT) guide. Stereolithographic guides were created using CAD/CAM technology and planning software. All of the stereolithographic guides had 2 holes for the right second premolar and molar. After implant was placement, the model was positioned for CT scan to compare the implant position against that which had been planned implant. The linear and angular deviations between the planning data and surgical results were evaluated. Results: The average differences between the planned and actual implant position in mesiodistal and buccolingual direction and angles of implants showed a considerable reduction in CAD/CAM group versus the conventional group. Conclusion: This system showed promising accuracy with respect to the planned implant position within the limitations of this study.
