传统后牙固定桥桥体多采用金属咬合面与塑料联合组成。由于塑料有硬度差、易磨损、颜色不稳定等缺点,表现在临床上,最为多见的是因刷牙不当而造成塑料有不同程度的磨损,其次是塑料与金属部分脱离,以及桥体或连接体折断等情况也屡见发生。为避免或减少上述问题,我们自1983年来,采用金属全冠与塑料联合桥体制作固定桥500多例,经1～8年的临床观察,效果良好。现介绍供同道们参考。
Traditional fixed bridge abutments and more teeth with a metal surface and plastic joint composition. Due to the poor hardness of plastic, easy to wear, color instability and other shortcomings, manifested in clinical practice, the most common is due to improper brushing caused by varying degrees of plastic wear and tear, followed by plastic and metal part of the detachment, and bridge or connection Break the body and other conditions are also common occurrence. To avoid or reduce the above problems, since 1983, we have used metal crowns and plastic bridges to make more than 500 fixed bridges. After 1 to 8 years of clinical observation, we have achieved good results. Now for reference fellow.
