Comparative Study of EverX Posterior and Ribbond for the reinforcement of weakened teeth with class II cavities

Abstract

This review article focuses on a comparative study between the materials EverX Posterior and Ribbond, used for the reinforcement of weakened teeth with Class II cavities. Their mechanical properties, structural composition, and clinical performance are analyzed to determine which material provides greater strength and durability in posterior restorations. The article examines recent scientific evidence regarding the ability of these materials to distribute occlusal stresses and prevent the propagation of fractures in teeth with significant structural loss. It also discusses the advantages, limitations, and clinical considerations of each material, emphasizing their applicability in modern restorative dental practice. Through the review of literature published between 2020 and 2025, this work aims to offer an updated perspective that serves as a guide for the selection of the most suitable material in cases of severe dental weakening. Finally, the clinical implications and future research directions related to the development of more effective and biocompatible reinforcement systems are highlighted.
