Resin matrix ceramics in dentistry

Abstract

Resin matrix ceramics (RMCs) represent an innovative category of CAD/CAM restorative materials that combine the high durability of ceramics with the elasticity and repairability of polymer resins. This thesis analyzes the structure, classification, and clinical performance of RMCs, highlighting their unique ability to mimic the biomechanical properties of natural dentin and enamel. Through a comprehensive literature review, the research evaluates the various subgroups of RMCs, including resin nanoceramics and polymer-infiltrated ceramic networks (PICNs), and their suitability for minimally invasive restorations such as inlays, veneers, and implant-supported crowns. Clinical data indicates high survival rates exceeding 95% over three years, with a notable advantage in stress distribution that reduces the risk of catastrophic fractures compared to traditional brittle ceramics. Despite these benefits, limitations such as lower wear resistance relative to lithium disilicate and a need for further long-term clinical research on fatigue performance are identified. Ultimately, the integration of RMCs into digital workflows facilitates efficient, single-session restorative procedures that bridge the gap between artificial reconstruction and natural dentition.
