影响前牙粘结桥固位力的因素很多。在(?)关系正常情况下,粘结桥固位力的大小主要依赖二个因素;一是粘结剂的粘合力;二是粘结桥舌背与牙体接触面积的摩擦力。为了增加粘结桥的固位力,国外曾报道在金属舌背上增加邻面板。笔者根据临床观察及制作实践,认为金属舌背加邻面板粘接桥能充分利用缺失区基牙邻面的有利因素达到增加固位 There are many factors affecting the retention force of the anterior bridge bond bridge. In the normal relationship between (?), The size of the bond bridge retentive force mainly depends on two factors; First, the adhesive bond; Second, the contact surface of the bridge of the tongue and tooth contact friction. In order to increase the retentive force of the bonded bridge, it has been reported in foreign countries that an adjacent panel is added on the metal tongue back. According to the author's clinical observation and production practice, that the metal tongue plus the adjacent panel adhesive bridge can make full use of the missing area abutment abutment favorable factors to achieve increased retention
