近年来，人们对人工牙槽的技术进步进行了研究。然而，残肢残端与假体窝的成功拟合仍然存在一定的局限性。剪切应力接触界面的研究对于改进套筒的设计配合，了解套筒内部发生的作用机理具有重要意义。本文对手工压铸模套筒接触界面处的剪应力和剪切角进行了分析。结果表明，与其他位置相比，前近端和后近端剪切应力值较高。其结果对临床及窝位矫正有一定的参考价值。
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.
