Palpation is important medical technic to make proper diagnosis of symptomatic state. It requires a lot of palpation experience under guidance of richly experienced medical doctors. However, there is few practical training in the dental education in Japan. Then, development of a palpation training system is desired with no patient risk for dental students. According to the previous background, a palpation training system for maxillofacial disorder is developed using virtual reality and a haptic interface. In the paper, we focus on the elastic deformation analysis for the system. The particle method of meshless analysis (Moving Particle Semi-implicit: MPS) is newly introduced. We study on its adequacy of MPS about linear (small) and non-linear (large) deformations of soft tissue with uniform and non-uniform stiffness using Finite Element Method (FEM).
