. Guided surgeries are becoming common in modern dental industry, and are used for a variety of treatments. The purpose of this study is to apply a dental software toolkit for virtual simulation of dental drill guided surgery. The hypothesis is that if a virtual simulation of dental drill guided surgery can be done, then the preplanned surgery can also be verified before the actual surgery. The dental drill guided concept is a planning and surgical implementation system that enables surgery with the help of a drill guide based on planning supported by computer aided design tools and CT-scan. The variation simulation predicts the final positions of the pre-defined critical production dimension at the apical part of the fixture. The results are based on variation simulation of two dental drill guided surgeries: Maxilla, seven implants and Mandible, nine implants. Maxilla resulted in a safe surgery while Mandible needed an optimization of the implant positions before the surgery. By analyzing the results, it was also found that both plans could be optimized in order to minimize the geometrical variation. Finally, it was found that the method used was suitable for predicting guided surgeries to achieve safer treatments.
