Jan 1, 2015 · The direct-placement esthetic materials used most commonly are (1) composite resin, (2) glass ionomer cement, (3) resin-modified glass ionomer cement (also called hybrid ionomer), and (4) compomer. These are listed in their chronologic order of development.

Compomers are resin-based materials like dental composites, and the components are largely the same. The setting reaction is similarly a polymerisation process of resin monomers (e.g. urethane dimethacrylate) which have been modified by polyacid groups, and is induced by free radicals released from a photoinitiator such as camphorquinone.

Jan 9, 2015 · In appearance and performance, compomers are more closely related to composite resins than glass-ionomer cements. Trends in material properties for resin composites, compomers, conventional and resin-modified glass-ionomer cements are set out in Fig 2-1.

Compomers are resin-based materials but their composition varies between brands. In general, compomers contain: polymerisable resins with methacrylate and polycarboxylate groups. glass filler particles, such as fluoroaluminosilicate, strontium fluorosilicate or barium fluorosilicate glass.

Jun 30, 2005 · Compomer = Polyacid modified GI (but more closely related to a composite). Sets with only light polymerization (no acid-base reaction). Must also be etched and bonded beforehand.

Jan 1, 2015 · A further addition to this already extensive range of resin-based dental materials is the polyacid-modified resin composite, or compomer for short. In this chapter we will first consider the resin composites and then explore how the compomers differ from the resin composites.

Compomers are basically polyacid modified resins with filler constituents derived from composite and glass ionomer compositions. The resultant material is a low–fluoride-releasing resin composite. Compomer resins contain vinyl groups that can be polymerized by visible light activated initiators.

By combining the characteristics of the composite resins and glass-ionomers, hybrid products knowns as giomers have been obtained; giomers represent a special class of composites that offer both protection against caries and functional and esthetic results, by incorporating particles of pre-reacted glass filler in the matrix of the composite ...

Polyacid-modified composite resins are a class of composite material used in dental repair. Similar to conventional composite materials, compomers also have two distinct phases. These phases are different in form and chemical composition and are mutu-ally insoluble in each other.

A compomer is basically used to describe a single component, water free, light cured composite consisting of acid-modified dimethacrylate reinforced with silanized calcium-, barium-, strontium-, and aluminum-fluorosilicate glass particles [112].
