Evaluation of root-resected teeth. Results after 10 years.
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.
