PEEK Retentive Elements Versus Conventional (PEEK)
Novel PEEK Retentive Elements Versus Conventional Retentive Elements in Mandibular Overdentures: A Randomized Controlled Trial
研究概览
详细说明
Background. Many patients suffer from lack of retention of conventional mandibular overdentures due to loss of clip retention over time. Computer-aided design-computer-aided manufacturing (CAD-CAM) milled polyetheretherketone PEEK materials may be used for construction of retentive housing and clip for improving retention of implant-supported overdentures.
Objective . To compare retention and patient satisfaction of implant-supported mandibular overdentures retained by conventional nylon clip and metal housings for ball attachments versus PEEK clip and housings.
Methods: Twenty-two participants were divided into 2 equal groups (n=11). The conventional group received implant-supported mandibular overdentures retained by metal housings and nylon retentive elements, while the PEEK group received implant-supported mandibular overdenture retained by PEEK retentive element and housings.The PEEK retentive elements were made by using computer-aided design and computer-aided manufacturing (CAD-CAM).Evaluation included measuring the retention by applying a gradual pulling up force by forcemeter and patient satisfaction with a 7-point visual analog scale (VAS) at overdenture insertion , 3,6, and 12 months subsequently by research interviewer.
