Recently, finite element analysis (FEA) has been use frequently to determine the biomechanical movement of teeth. However, the condition of the jaw bone and periodontal ligament varies in the reports, and it has not been clarified.<BR>The purpose of this study was to clarify the differences between actual displacement of human teeth obtained by loading experiment and numerical values of the FEA model. Then the influence of the condition of the jaw bone, periodontal ligament and a fixed condition exert on the analysis value was evaluated using a mandibular premolar FEA model of the buccolingual section.<BR>As a result, it was one of the effective means to control horizontal displacement of compact bone and to gradually increase Young's modulus of periodontal ligament from tip to cervical margin, causing displacement under pressure of the two-dimensional FEA model to approximate actual values.
