Abstract
ABSTRACT Resin matrix ceramics consist in a polymeric matrix with predominantly inorganic refractory compounds which may include porcelain, glass, ceramics, and glass ceramics, and are divided into three subgroups: Nanoceramics, Vitroceramics, and Zirconia-silica. The aim of this study was to compare, through a literature review, the mechanical and biological properties of resin matrix ceramics, with glass matrix ceramics and polycrystalline ceramics. After reviewing 44 articles found in the US National Library of Medicine (PubMed) database (studies published in English, human clinical studies, in vitro or in vivo studies) that evaluated some properties of this material, such as elasticity modulus, wear resistance, adhesiveness, stain resistance and hardness, this article concluded that, although they belong to the same group, resin matrix ceramics are different from each other due to their microstructures. Moreover, when compared to other ceramic groups, it showed some superior properties, such as flexural strength, fatigue strength and internal adaptation.
Highlights
Launched in the market around 1962, dental composite resins have undergone several changes to improve their properties for having more space in the market
Resin matrix ceramics are materials with an organic matrix highly filled with ceramic particles
Resin ceramics aim to obtain a material that simulates the elasticity modulus of the dentin and that is more adjustable. These resin matrix ceramic materials can be divided into several subfamilies according to their inorganic composition: resin nanoceramic (Lava Ultimate, 3M ESPE; Cerasmart, GC America); glass ceramic in a resin interpenetrating matrix (Enamic, Vita); zirconia-silica ceramic in a resin interpenetrating matrix (e.g., Paradigm MZ100, 3M ESPE; Shofu Block HC, Shofu) [8]
Summary
Launched in the market around 1962, dental composite resins have undergone several changes to improve their properties for having more space in the market. The mechanical properties of different types of composite resins, such as hardness, tensile strength, compression and shear, increase the clinical success of the restorative material [2,3]. These properties are directly related to the polymeric matrix (monomer composition), inorganic filler (type, size and distribution of filler) and bonding agent. The incorporation of nanoparticles helped to obtain a restorative material capable of being used in all areas, with high initial polishing, superior gloss retention (typical of microparticles), as well as excellent mechanical properties such as wear resistance in areas with high chewing stress (typical of hybrid composites) [4].
