Dental porcelain (also known as dental ceramic) is a dental material used by dental technicians to create biocompatible lifelike dental restorations, such as crowns, bridges, and veneers. Evidence suggests they are an effective material as they are biocompatible , aesthetic , insoluble and have a hardness of 7 on the Mohs scale .
Poly(methyl methacrylate) (PMMA) is a synthetic polymer derived from methyl methacrylate. It is a transparent thermoplastic , used as an engineering plastic . PMMA is also known as acrylic , acrylic glass , as well as by the trade names and brands Crylux , Hesalite , Plexiglas , Acrylite , Lucite , and Perspex , among several others ( see below ).
MMA is a raw material for the manufacture of other methacrylates. These derivatives include ethyl methacrylate (EMA), butyl methacrylate (BMA) and 2-ethyl hexyl methacrylate (2-EHMA). Methacrylic acid (MAA) is used as a chemical intermediate as well as in the manufacture of coating polymers, construction chemicals and textile applications. [15]
The resins are the most commonly used, they are either made of cellulose acetate, polycarbonate or poly-methyl methacrylate. Other chemically activated resins include poly-R methacrylates: these are methacrylates with ethyl or isobutyl substances added to increase the strength of material.
Radiopacity in dental materials is an important property that allows for distinguishing restorations from teeth and surrounding structures, assessing the absorption of materials into bone structure, and detecting cement dissolution or other failures that could cause harm to the patient.
In the late 1970s, tooth adhesion phosphate monomer 2-methacryloyloxethyl phenyl hydrogen phosphate (Phenyl-P) was developed for tooth-saving restoration techniques. [ 3 ] 4-Methacryloyloxyethyl trimellitic acid anhydride (4-META) that adheres to not only tooth structures but also dental alloys, was developed almost at the same time. [ 4 ]

Dental composites. Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength.
