Establishing a finite element model of mandibular first molar with analysis of the stress distribution to each of the tooth parts on the model. The right mandibular first molar in vitro was scanned and the image was processed. The three dimensional finite-element model was established by the special software and loaded on it. Stress distribution on each part of the tooth was obtained. The maximum values of compressive stress, tensile stress and mises stress were calculated. In the research and analysis of the tooth stress, the finite element method is simple, effective, safe and reliable.
