近两年来笔者作前牙针道支架粘接桥20余例,效果满意,报告如下。 一、器材:EB复合树脂、塑胶牙、不锈钢丝等。 二、适应症:个别前牙缺失,基牙不松动,咬合关系及牙周情况基本正常者。 三、作操方法: 1.支架形成:先用小球粘在失牙两侧基牙邻面离切缘2～3毫米处作一小凹,再用小裂钻磨一深约1.5-2毫米之针道。截直径1毫米不锈钢丝一段,其长度=失牙间隙宽度+基牙针道深度,将钢丝中段磨扁,并弯成V形,两端插入针道孔内,
In the past two years, I made a bridge for the anterior teeth needle track stent more than 20 cases, the effect is satisfactory, the report is as follows. First, equipment: EB composite resin, plastic teeth, stainless steel wire. Second, the indications: a few missing anterior teeth, abutments are not loose, occlusal and periodontal conditions were normal. Third, exercise methods: 1. Stent formation: first with the ball stuck to the teeth on both sides of the abutment abutment away from the edge of 2 to 3 millimeters for a small concave, and then a small drill deep grinding about 1.5-2 Mm needle Road. Cut a section of stainless steel wire with a diameter of 1 mm, its length = the width of the lost tooth gap + the depth of the abutment needle track, flatten the middle section of the wire and bend it into a V shape with both ends inserted into the needle track hole,
