Retention and satisfaction of single-implant mandibular overdentures in geriatric patients: A prospective study

TL;DR

A study shows that single-implant mandibular overdentures are effective and satisfying for elderly patients.

Contribution

This study confirms the reliability and patient satisfaction of single-implant overdentures in elderly patients.

Findings

A 97% implant survival rate was observed over 12 months.

Patient satisfaction scores increased significantly and remained stable.

Minimal maintenance was required for prosthodontic upkeep.

Abstract

Single-implant mandibular overdentures have been proposed as a minimally invasive and cost-effective alternative to the two-implant
standard, particularly suitable for geriatric patients. In this prospective study, 33 elderly patients received a single midline implant
supporting an overdenture, and outcomes were evaluated for implant survival, prosthodontic maintenance, and patient satisfaction. The
results demonstrated a 97% implant survival rate, with only minimal maintenance interventions such as matrix replacement and denture
base adjustments required. Patient satisfaction improved markedly, rising from a baseline mean score of 45.0 to over 82.0 at 3 months,
and remained stable at 12 months (p < 0.001). These findings confirm that single-implant mandibular overdentures provide reliable
retention, high satisfaction, and favorable survival outcomes, establishing them as a practical solution for geriatric populations.
