Effect of Resilient Soft Liner and Clip Attachments on Peri-Implant Tissue in Splinted Mini-Implant Retained Mandibular Overdentures (Randomized Clinical Trial)

Abstract

A total of fourteen completely edentulous patients were selected to participate in this study from the out-patient clinic of the Prosthodontic Department, faculty of Dentistry, Ain Shams University. Patients were precisely selected and thoroughly examined in an attempt to reduce human variables and eliminate any factor that might adversely affect the results of this study. Selected patients were divided randomly into two equal groups of seven patients each: Group I: Seven patients received a complete denture for the maxillary arch and a mandibular overdenture supported by four mini implants in the anterior interforaminal region of the mandible splinted by a cemented bar and retained by clip attachment. Group II: Seven patients received a complete denture for the maxillary arch and a mandibular overdenture supported by four mini implants in the anterior interforaminal region of the mandible splinted by a cemented bar and retained by chair side resilient soft liner. Standard clinical and laboratory techniques were followed for denture construction for all patients. Surgical installation of the implant was performed under strict aseptic conditions and delayed immediate loading protocol was followed.
