Three Dimensional Stress Analysis in the Crowned Human Teeth

The stress distribution on a mandibular right second premolar tooth was investigated by using a three dimensional finite element model. Three crowns cast in different materials were subjected to 11 simulated biting force of 100 N with six different postures. The distribution of compressive and tensile stresses on cole and apex was evaluated by using a computer program. The stress component in transverse direction on the cole with porcelain crown was found to be most compatible with enamel when compared with other materials
