Overview

Prospective cohort study demonstrates high long-term implant survival and patient satisfaction in edentulous maxillae, suggesting three-implant stud-retained overdentures are a viable solution.

Key Points

To assess the long-term clinical performance and patient-reported outcomes of a palateless, metal-reinforced maxillary overdenture retained by low-profile stud attachments on three implants.
Prospective cohort study of consecutive edentulous patients (N=32) treated at a private specialty clinic between March 2007 and October 2016 with at least five years of follow-up.
Primary outcomes evaluated patient satisfaction (Denture Satisfaction Scale) and oral health-related quality of life (OHIP-20); secondary outcomes evaluated peri-implant bone loss, implant success, and prosthetic maintenance needs.
Patient satisfaction scores and OHIP-20 ratings showed significant differences and improvements compared to pre-treatment values (Kruskal-Wallis tests).
Estimated implant success reached 0.95 at 168 months, with 38% of implants showing no or minor bone loss and 17% exhibiting >2 mm bone loss after a mean follow-up of 6.7 years.
Estimated prosthesis success without adverse events or maintenance repairs was 0.55 at 156 months.
