• Mechanical analysis of the tooth root and alveolar socket under extraction force is important in the serarch for more effective and safer methods of extraction, and also to prevent fractures of the tooth root and alveolar process and other accidents. A study was, therefore, made of the mechanical behavior of the tooth and alveolar socket under various loadings using the finite element method. A computer numerical analysis.<BR>A two-dimensional numerical model of the lower first premolar was developed, and loaded with cantilever and wedge forces with elevator, and forceps force. In particular, elevator depth insertion direction of insertion, and blade angle were changed in order to investigate the effects of extraction force by elevation. As a result, mechanical behavior of the tooth root and the alveolar socket under loading was clearly shown, and conventional tooth extraction methods were justified by stress analysis.
