O uso de fibra de polietileno em restauração de resina composta e fibra de vidro em prótese adesiva: um relato de caso

Abstract

Biomimetic principles have been extensively investigated due to their aim of replicating the natural properties of teeth, thereby enhancing the integration of restorative materials within the oral environment. Among the most salient innovations is the use of polyethylene fibers, such as Ribbond®, in the fabrication of composite resin restorations. This method offers mechanical and clinical advantages, including uniform distribution of masticatory forces, reduced risk of fractures, improved control over polymerization shrinkage, and increased longevity of restorations. Additionally, its utilization permits a more conservative treatment approach, preserving the remaining dental structure and delivering superior esthetic outcomes for the patient. Although not novel, yet still highly effective, the application of these fibers—as well as resin-impregnated glass fibers—can also be employed in the fabrication of pontics in edentulous areas. Therefore, the objective of this study is to present the clinical application and sequential procedural steps for the use of polyethylene fiber reinforcement in direct composite resin restoration of an anterior tooth and adhesive restoration to reestablish both esthetics and function.
