Background: The accuracy considerations of alignment of skull bone loss and artificial model of implant are presented. In standard surgical treatment the application of prefabricated alloplastic implants requires complicated procedures during surgery, especially additional geometry processing to provide better adjustment of implant. Rapid Prototyping can be used as an effective tool to generate complex 3D medical models and to improve and simplify surgical treatment planning. The operation time can also be significantly reduced. The aim of the study is adjustment accuracy analysis by measurements of fissure between the bone loss and implant. Material/Methods: The 3D numerical model was obtained from CT imaging with Siemens Sensation 10 CT scanner. The physical models were fabricated with 3DP Rapid Prototyping technology. The measurements were performed in determined points of the bone loss and implant borders. Results: Maximal width of fissure between bone loss and implant was 1.8 mm and minimal 0 mm. Average width was 0.714 mm, standard deviation 0.663 mm. Conclusions: Accuracy of 3DP technique is enough to create medical models in selected field of medicine. Models created using RP methods may be then used to produce implants of biocompatible material, for example by vacuum casting. Using of method suggested may allow shortening of presurgery and surgery time.
