There are only a few long-term investigations on root-resected teeth in the literature. This article is a 10-year review of 28 root-resection cases, which mainly had been used as bridge abutments. The periodontal, prosthetic, and endodontic problems were evaluated. After 10 years a total failure rate of 32% was observed. The analysis of the failure causes revealed that endodontic--not periodontal--complications were predominating. The study also includes a comparison of root-resected teeth restored with root screws and composite cores versus those which had been restored with cast gold dowels, showing that both types of reconstruction had the same durability concerning the risk of root fractures or loss of retention.
文献中仅有少数关于截根牙的长期研究。本文是对28例截根病例的10年回顾，这些病例主要用作桥基牙。对牙周、修复和牙髓问题进行了评估。10年后观察到总失败率为32%。对失败原因的分析表明，牙髓并发症而非牙周并发症占主导。该研究还比较了用根螺钉和复合核修复的截根牙与用铸造金桩修复的截根牙，结果表明两种修复类型在牙根骨折或固位丧失风险方面具有相同的耐久性。
