Abstract：
An abutment having edentulous space on both sides is referred to as a pier abutment. The rehabilitation of a patient whose primary concern when they first came to the hospital was missing teeth is discussed in this case report. When using a pier abutment for a fixed dental prosthesis, there is a problem with fulcrum and torqueing pressures at the intermediate abutment. Forces on the pier abutment may become localized as a result of using a rigid connector. It has been suggested that non-rigid connectors be used to overcome this. Here, using a non-rigid connector as a stress breaker resulted in less stress being placed on the prosthetic assembly and abutment. This article offers a clinical case report that details the use of a non-rigid connector in a pier abutment scenario for rehabilitation.
摘要：
在两侧具有无牙空间的桥台被称为墩桥台。在此病例报告中讨论了患者的康复，该患者首次来医院时主要关心的是牙齿缺失。当使用墩基牙固定假牙时，中间桥台的支点和扭转压力存在问题。由于使用刚性连接器，桥墩上的力可能会局部化。已经建议使用非刚性连接器来克服这一点。这里,使用非刚性连接器作为应力断路器导致较小的应力被放置在假体组件和基台上。本文提供了临床病例报告，详细介绍了在桥墩基台康复方案中使用非刚性连接器的情况。
