258 units of fixed crowns and inlays, produced with the powder metallurgic Degusint-System (Degussa), were clinically evaluated 6 and 12 months after insertion. Periodontal examinations, especially of the crevicular fluid flow, failed to show higher amounts of marginal inflammation due to the subgingival localization of the margins of fixed sintermetallic restorations compared with reference teeth of the same individual. Plaque accumulations during the wearing period were quite the same as those observed with crowns.
采用粉末冶金德固赛系统（德固赛公司）制作的258个固定冠和嵌体，在植入后6个月和12个月进行了临床评估。牙周检查，特别是对龈沟液流量的检查，结果显示，与同一个体的对照牙相比，由于固定烧结金属修复体边缘位于龈下，并未发现边缘炎症增多。在佩戴期间，菌斑堆积情况与冠修复时观察到的情况完全相同。
