Reinforced Polymethyl Methacrylate Resin Using Grapheme Derivative For an “All-On-4” Implant- Supported Definitive Mandibular Prosthesis – A Case Report

ABSTRACT

Since the inception of implant dentistry, implant-supported metal-acrylic resin hybrid prostheses are the major prostheticdevices given to restore physiological and esthetic functions of oral tissues of edentulous or partially edentulous patients. Theclinical performance of the most commonly used acrylic resin in the fabrication of dentures, namely, polymethyl methacrylate(PMMA) resin determines its long-term deformation and wear resistance. However, its poor mechanical resistance to wearand tear poses a major setback. An attempt to incorporate graphene derivative with PMMA resin in prosthesis fabrication hasdemonstrated significant improvement in the mechanical strength as per literature. This case report presents rehabilitation ofedentulous mandibular jaw and also briefly states the properties of graphene and the polymerization process of the resin withthe graphene derivative.
