No results posted yet for this study

Summary

Although there are many studies in the literature concerning methods of bonding of mandibular retainers whether directly or indirectly, there is a very limited evidence regarding their chair side time and bond failure. Also there are scarce data on fixed mandibular retainers bonded using 3D printed positioning tray.Thus, conducting a well-designed randomized clinical trial evaluating the chair side time and bond failure of 3d printed positioning tray and direct bonding method of fixed mandibular retainer.Null hypothesis is thatThe time needed for direct indirect bonding using 3D digital positioning tray of a mandibular fixed retainer is shorter than the time needed for direct bonding, and there is no difference in failures between the 2 bonding methods
