1986年以来,笔者在实践中设计了一种新方法,暂名为“套筒式冠桩”,现介绍如下。 一、适应证:本法适用于桩冠根内断桩后的义齿修复。 二、制作方法:①除净附着在根面上的食物残渣、牙垢及软化牙本质。②用探针探查断桩周围的牙体组织健康状况,选用小球钻或701号裂钻紧贴断桩周围向根端方向磨除粘固剂利少量牙本质,形成一个以原金属桩为中心的环状洞,磨除深度,要求洞深加上已露出断桩氏度约为1/4～1/3很长(一般洞深3～4mm)。环状洞形成后,用较细圆柱
Since 1986, the author has designed a new method in practice, tentatively named “sleeve-type crown pile”, are introduced as follows. First, the indications: This law applies to the post crown crest broken denture repair. Second, the production methods: ① In addition to the net attached to the root of food residue, tartar and soften the dentin. ② probing with the probe around the broken pile of tooth tissue health status, use a small ball drill or 701 crack drill close to the broken pile around the direction of the root end to remove cement and a small amount of dentin to form a metal pile for the The center of the ring hole, grinding depth, requires the depth of the hole has been exposed stump broken degree is about 1/4 ~ 1/3 is very long (general hole depth 3 ~ 4mm). After the formation of circular holes, with a thin cylinder
