Clinical abrasion of denture teeth has certain implications when dentures are worn in excess of the average useful lifetime. The purpose of this study was to evaluate clinical denture tooth wear over a period of 3 years.
The wear of six commercially available denture teeth (Premierdent, Acrotone, vitapan, Rx1, Duravite, and Ivoclar Orthosit) and a seventh combination of teeth was compared. Seventy patients with complete dentures were divided into seven groups of 10 each to form the study population.
There were no significant differences among the commercial denture teeth. Porcelain/Vitapan teeth exhibited the highest amount of abrasion. Significant wear was also measured between the Ivoclar Orthosit and Porcelain/Vitapan teeth.
当义齿佩戴时间超过平均使用寿命时，义齿牙齿的临床磨损具有一定影响。本研究的目的是评估3年期间义齿牙齿的临床磨损情况。
比较了六种市售义齿牙齿（Premierdent、Acrotone、维他灵、Rx1、Duravite和义获嘉Orthosit）以及第七种牙齿组合的磨损情况。70例全口义齿患者被分为七组，每组10人，组成研究人群。
市售义齿牙齿之间无显著差异。瓷/维他灵牙齿磨损量最大。义获嘉Orthosit牙齿与瓷/维他灵牙齿之间也测得有显著磨损。
