Abstract
Introduction: Conventional complete dentures are the most commonly used treatment option for edentulous patients. To address their drawbacks, a single mandibular midline implant has evolved as an alternative to a two-implant assisting overdenture. Denture bases have been reinforced with a variety of materials to manage unreinforced overdentures’ deformation and fracture vulnerability. The modified Polyether-ether ketone is the most recent and strongest non-metallic material introduced in dentistry. Aim: The aim of the study is to evaluate and compare the effect of Biocompatible High Performance Polymer denture base reinforcement material in relation to the conventional acrylic denture base on strain on the ridge area and around a single midline implant mandibular overdenture. Materials and Methods: Two identical mandibular epoxy resin models were utilized. One root-form implant was screwed into the midline area of each model. 12 mandibular overdentures were constructed and divided equally into two groups: The denture base in group A was unreinforced, whereas in group B, the acrylic denture base was reinforced with Biocompatible High Performance Polymer (BioHPP). Four linear strain gauges were glued to the epoxy resin, and their lead wire’s free ends were attached independently to a strain meter. Under central and unilateral loading of 100 N, strain values were recorded. Results: The findings revealed that there were significant differences in strain values between the acrylic resin group and the reinforced group. Conclusions: The BioHPP showed lower microstrain values and exhibited a more favorable stress distribution on the ridge and around the implant.
