简要总结
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).

研究组 & 干预措施
Group I (bar locator): Patients were given overdentures with bar locator attachments
Group I received mandibular overdentures with a bar locator attachment , specially designed milled bar with parallel walls was built for this group, and two holes were drilled in the top surface of the bar using a 1.7 mm bar drill to create the threaded site in the waxed bar, followed by a 2.0 mm bar tap. The locator female component was then connected to the corresponding site using a customised rider.
干预措施: overdenture (Other)
group2, Patients were given overdentures with bar clip attachment.
bar clip attachment. Patients received mandibular overdentures with bar clip attachments. A plastic prefabricated bar was cast in cobalt-chrome alloy. Group II patients received mandibular overdentures with bar clip attachments. A plastic prefabricated bar was cast in cobalt-chrome alloy.
干预措施: overdenture (Other)
