Abstract

Abstract: PURPOSE: To analyze the retention of 3 different Co-Cr-Mo alloy clasps on premolars, and provide information for clinical design of aesthetic clasps. METHODS: An EZ20 force measuring instrument was used to record the retention of Co-Cr-Mo alloy casting aesthetic clasps when they were dislodged from undercuts of different depths (0.25, 0.50, 0.75 mm) on premolars. The data were analyzed with SPSS 22.0 software passage. RESULTS: The clasp retention in groups of 0.25 and 0.5 mm undercut was three-arm clasp > varied Y-shaped clasp > modified RPI clasp. In the group of 0.75 mm undercut, the clasp retention was varied Y-shaped clasp > three-arm clasp > modified RPI clasp after circulations. CONCLUSIONS: A varied Y-shaped bar clasp of 0.75 mm undercut depth is suitable for premolar both for its adequate retention and aesthetic effect.
