抄録

In our clinic, the four-dimensional analysis of mandibular movement has mainly been used to diagnose jaw function disorders. In present, we are considering its application for patients with occlusal issues. Consequently, an improvement in system accuracy is required. However, metal artifacts cause distortions in the 3D-cranio-mandibular model construction process, which leads to accuracy concerns. The purpose of this present study was to grasp the accuracy differences caused by the oral metal restorations in reconstructed 3D-craniomandibular models from CT data, and scanned dentition models. The accuracy of the reconstruction was confirmed from comparing the occlusal contacts in VR space and real space. The VR contact areas in the dry skulls without and moderate restoration showed a close similarity to real occlusal contacts. However, the VR contact areas in the dry skull with numerous restorations was not similar to the real contacts. From these results, it is considered that metal artifacts decrease the accuracy of model reconstruction.
