"Retention and Quality of Life in Mandibular Overdentures Using Two Attachment Systems: A Randomized Clinical Trial"

NCT07513155 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 26

Summary

This randomized clinical trial investigates the effect of two different attachment systems-Equator and Novaloc-on the retention, patient satisfaction, and oral health-related quality of life of mandibular implant overdentures. Completely edentulous patients often experience reduced denture stability, compromised chewing ability, and diminished oral function with conventional complete dentures. Implant-retained overdentures have been shown to improve retention, stability, and overall patient satisfaction. Equator attachments offer a small, resilient, and self-aligning system with variable retention levels, while Novaloc attachments feature innovative PEEK caps and a diamond-like carbon coating designed to reduce wear and maintain long-term retention. This study aims to determine whether one attachment system provides superior functional outcomes and patient-centered benefits, thereby guiding clinicians in optimizing overdenture therapy for edentulous patients."

Conditions

  • Edentulous Alveolar Ridge In Mandible

Interventions

PROCEDURE

OT-Equator Attachment

Two implants will be restored using OT attachment systems, with the mandibular denture retained over these attachments through corresponding metal housing

PROCEDURE

Novaloc Attachment

Two implants will be restored using Novaloc attachment systems, with the mandibular denture retained over these attachments through corresponding metal housing
