Evaluation of three attachment systems for mandibular and maxillary implant overdentures: A Randomized Clinical trial - Trial PACTR202307729042647

Timeline & Enrollment

Summary

Background: Implant supported overdenture improves on the drawbacks of conventional complete denture, providing improve retention, oral health and quality of life. There are some debatable factors to be considered for the success of implant supported dentures especially for the choice of an implant attachment that gives the desired long term maintenance outcome. These long-term maintenances are loss of retention, plaque accumulation, fracture of prosthesis, attachments and implants. A new abutment locator R-Tx was developed recently to give good clinical outcome but there are concerns of long-term maintenance such as rapid loss of retention and plaque accumulation. The aim of this study is to determine the long-term maintenance of implant abutment system such as retention, plaque accumulation, fracture of implant abutment of ball, bar, locator R-Tx system and to compare the long-term maintenance of these 3 abutment systems.OBJECTIVES1.To determine the force required to dislodge implant overdenture from attachment using locator R-Tx , Ball and Bar attachments.2.To determine the level of plaque accumulation on implant- attachment surface using locator R-Tx , Ball and Bar attachments.3.To compare the force required to dislodge implant overdenture from locator R-Tx , Ball and Bar attachments.4.To compare the level of plaque accumulation on implant- attachment surface using locator R-Tx , Ball and Bar attachments..5.To determine secondary outcomes/Complications involving attachment or prostheses.
