Abstract

Aim: To compare the accuracy of implant placement when using tooth supported surgical guide using a fully guided surgical guide design performed on different software of them are non-dental software (Blenderfordental) verses a dental software (Exoplan).
Subjects and methods: Twenty study models, simulating patients with a missing upper left first molar, were divided into: Group I (Exoplan) and Group II (Blender). Each group underwent digital implant planning and surgical guide fabrication using their respective software. A virtual model, derived from a physical typodont, served as the basis for implant planning. DICOM data of a physical model were integrated into the planning software. Surgical guides were designed and fabricated using the software's features. After implant placement, postoperative scans of scanbodies attached to the implants was done. By superimposing the preoperative and postoperative scans, deviations in implant position were measured along the buccolingual, mesiodistal, and apico-coronal axes.
Results: No statistically significant differences were observed between the two groups for buccolingual (p=0.83), mesiodistal (p=0.41), and depth (p=0.75) dimensions.
Conclusion: Open-source software designed for non-dental applications like Blenderfordental can be utilized to create dental implant surgical guides with accuracy that is not significantly different from commercially available dental implant treatment planning software like Exoplan.
