Brief summary

Purpose: This study evaluated patient satisfaction and oral health-related- quality of life (OHRQoL) with implant overdentures retained with bar locator versus bar clip attachment for mandibular two-implant overdentures. Materials and methods: This study included sixteen edentulous patients. Every patient received new maxillary and mandibular dentures. Two dental implants have been embedded in the mandibular canine areas. The participants were randomly divided into two equal groups: Group I (bar locator): Patients were given overdentures with bar locator attachments, Group II (bar clip): Patients were given overdentures with bar clip attachment. Patient satisfaction (primary outcome) was measured by a visual analog scale (VAS). OHRQoL (secondary outcome) was measured by oral health impact profile (OHIP-14). Questions of VAS and OHIP-14 were evaluated after 3 months. The aim of this study was to document and report on the prosthetic complications associated with mandibular implant overdentures using bar locator and bar clip attachments. The study aimed to test the null hypothesis that the complications would not differ based on the type of retention (locator or clip).

Interventions

Patient satisfaction (primary outcome) was measured by a visual analog scale (VAS). OHRQoL (secondary outcome) was measured by oral health impact profile (OHIP-14). Questions of VAS and OHIP-14 were evaluated after 3 months The patients were divided into two equal groups.
