No results posted yet for this study

Summary

This study compares two different attachment systems, OT Equator and Ball and Socket, used to retain mandibular complete overdentures supported by a single dental implant. The study aims to evaluate and compare the retention of the two attachment systems over a 12-month follow-up period. The study will help determine whether one attachment system provides better and more stable retention of the overdenture over time.
