Abstract

Recently, the development of the technological advances of the prosthesis socket has been considered. However, the successful fitting of the prosthesis socket to the residuum stump is still not satisfied and existing limitations. The investigation of the shear stress contacting interface is important to improve the socket design fitting, and to understand the mechanism that happened inside the socket. In this study, the analysis of the resultant shear stress and the shear angle at the contacting interface of the Manual Compression Casting Technique (MCCT) socket type were presented. The results indicated that the higher the value of shear stress at the anterior proximal and posterior proximal in comparison with the other positions. The outcome would be benefit in clinical and improvement of the socket alignment.
