Detaljerad beskrivning
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.

patient satisfaction
Tidsram: 3 months to six months

measuring patient satisfaction using Visual analog scale (VAS) was used for the evaluation of overall patient satisfaction.
All questionnaires were taken by the same research interviewer (assisted interviewer) as he was blind about the type of prosthesis (double-blind) as the research interviewer is from another department
