Implant-supported Mandibular Overdentures in Very Old Adults

Study answer

What this study found

Implant overdentures significantly improved denture satisfaction (DS-VAS) and denture stability and maximum bite force after 3 and 12 months compared with conventional relines. Masseter thickness on the preferred chewing side increased with IODs; chewing efficiency did not differ between groups. Oral-health-related quality of life improved in both groups (OHIP-EDENT). BMI declined modestly in both groups. Authors conclude that converting existing dentures to implant overdentures is a feasible and beneficial option for very old, dependent edentulous patients, though the study was small and…

Study & population

Randomized, parallel-group, open-label controlled trial in very old institutionalized edentulous adults (age ≥75) requiring assistance with activities of daily living.

Key limitation

Small sample size and premature termination due to funding; dropout and missing data; open-label design; limited generalizability to non-institutionalized or healthier elderly populations; some secondary outcomes may be underpowered.
