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 ).
Dental porcelain (also known as ... Poly(methyl methacrylate) (PMMA) is the material of choice for denture teeth, however ceramic denture teeth have been, and still ...
Modern dentures are most often fabricated in a commercial dental laboratory or by a denturist using a combination of tissue shaded powders polymethyl methacrylate acrylic (PMMA). These acrylics are available as heat-cured or cold-cured types. Commercially produced acrylic teeth are widely available in hundreds of shapes and tooth colors.
Poly(ethyl methacrylate) (PEMA) is a hydrophobic synthetic acrylate polymer. It has properties similar to the more common PMMA, however it produces less heat during polymerization, has a lower modulus of elasticity and has an overall softer texture. [7] It may be vulcanized using lead oxide as a catalyst [8] and it can be softened using ethanol.
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.

An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...
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]
