Although mandibular implant-supported overdentures demonstrate high survival rates, uncertainty remains regarding their long-term biologic stability and maintenance burden, particularly across different attachment systems. Sixty edentulous patients were fitted with two-implant mandibular overdentures either by locator-type or ball retainers and followed up to a 5 years. At last follow-up, the survival rate of implants was 98.3% and 93.3% in terms of prostheses success; mean change of marginal bone was low. Maintenance requirements were frequent and mostly minor including insert/ matrix replacement and relines. Hence, long-term success is to be measured not just by survival.
