A new coping for overdentures. Part 1: A pilot study of the marginal precision.
The aim of this study was to investigate the marginal precision of new chairside copings prepared on 20 extracted teeth. The marginal fit was examined microscopically through 360-degree external observations. Subsequently, 10 new copings were adapted in vivo on 10 teeth that were planned for extraction. After extraction, the marginal fit was evaluated using the same protocol. The mean values of the marginal gap for the 2 groups (20 and 10 copings) were 24.1 and 32.6 microm, respectively. The marginal precision of the new copings was within the clinically accepted limits.
