1984年以来,我们将整体铸造金属舌侧翼板树脂粘结固定桥(下简称粘结桥)用于前牙缺失的修复,现将结果报告如下。 一般资料:本组前牙缺失患者76例,年龄21～55岁。其中缺失1牙43例,2牙33例;上颌51例,下颌25例;修复时间2～5年。 粘结桥设计:粘结桥的基本结构为:①固位部分:主要为舌侧翼板。为尽量扩大粘结面积,除利用两侧基牙的舌侧面外,亦应充分利用缺隙邻面及其轴面角(包括唇、舌轴角)。②支持部分:除利用舌侧隆突外,应使切缘形成切斜面肩台,上颌为舌斜面。
Since 1984, we have integrally cast metal lingual flaps resin bonded fixed bridge (hereinafter referred to as bond bridge) for the repair of missing anterior teeth, the results are reported as follows. General Information: This group of 76 patients with missing anterior teeth, aged 21 to 55 years old. Among them, there were 43 cases of 1 tooth missing and 33 cases of 2 teeth, 51 cases of maxillary and 25 cases of mandibular. The repair time was 2 to 5 years. Bonding bridge design: The basic structure of bonded bridges: ① retention part: the main lingual flap. In order to maximize the bonding area, in addition to the use of both sides of the lingual side of the abutment teeth, but also make full use of the lack of adjacent surface and its axial angle (including the lip, the angle of the tongue). ② support part: In addition to the use of lingual protuberance, the incision should be made to cut the incline shoulder surface, the tongue is the bevel.
