前牙残根传统上用桩冠修复、覆盖义齿或拔除后进行义齿修复。当冠桩长度不足则固位不良，覆盖义齿残根短期内出现龋坏不能长期保留，拔除残根导致牙槽骨丧失。鉴于此，我们自１９９２年以来，采用残根保留，冠桩联合粘结桥进行前牙义齿修复，取得较满意效果，现报告如下：１　 Traces of anterior teeth have traditionally been restored with post crowns, overdentures or prostheses after removal. When the length of the crest is insufficient, the retention is poor. The residual root of the overdenture can not be retained for a long time in the short term. The removal of the residual root causes loss of the alveolar bone. In view of this, since 1992, we have adopted the residual root, crown and joint bridge to repair the anterior denture and achieved satisfactory results. The report is as follows: 1
