A Pilot Randomized Clinical Study Comparing Patient-Reported Outcomes and Complications for Mandibular Implant Overdentures Retained by Different Splinted Attachment Systems

Mansoura University10 enrolled

Overview

This exploratory pilot randomized clinical study enrolled ten completely edentulous participants who experienced retention and stability problems with conventional mandibular complete dentures. Participants were randomly allocated to receive mandibular implant-supported overdentures retained by either a bar-locator attachment system (n = 5) or a bar-ball attachment system (n = 5). Denture satisfaction was assessed using the McGill Denture Satisfaction Questionnaire
