self-curing resin,

any resin that can be polymerized by the addition of an activator and a catalyst without the use of external heat. It is used in dental restorations and repairs. Also called activated resin, autopolymer resin, cold-curing resin, quick-cure resin.

resin (rez´in),

n broad term used to indicate organic substances that are usually translucent or transparent and are soluble in ether, acetone, and similar substances but not in water. They are named according to their chemical composition, physical structure, and means for activation or curing. Examples are acrylic resin, autopolymer resin (cold-curing resin), synthetic resin, styrene resin, and vinyl resin. See also methyl methacrylate; varnish, cavity.

resin, acrylic,

n 1. general term applied to a resinous material of the various esters of acrylic acid. It is used as a denture base material and also for trays and other dental restorations.
n 2. An ethylene derivative that contains a vinyl group (e.g., polymethacrylate [methyl methacrylate], the principal ingredient of many plastics used in dentistry).

resin, activated,

n See resin, autopolymer.

resin, autopolymer,

n (activated resin, autopolymerizing resin, cold-curing resin, direct restorative acrylic resin, self-curing resin), any resin that can be polymerized by an activator and a catalyst without the use of external heat.

resin cement,

n resin-based materials used as alternatives to common cement base materials, such as zinc phosphate. They are used with nonmetallic fillings such as ceramic, which will not bond to zinc phosphate, and when used with enamel and dentin bonding agents produce a much stronger bond than zinc phosphate.

resin, composite,

n a resin used for restorative purposes and usually formed by a reaction of an ether of bisphenol-A (an epoxy molecule) with acrylic resin monomers, initiated by a benzoyl peroxideamine system, to which is added as much as 75% inorganic filler (glass beads and rods, lithium aluminum silicate, quartz, and tricalcium phosphate).

resin, copolymer

n a synthetic resin that is the product of the concurrent and joint polymerization of two or more different monomers of polymers.

resin, direct restorative,

n See resin, autopolymer.

resin, epoxy,

n a resin molecule characterized by reactive epoxy, or ethoxyline, groups that serve as terminal polymerization points. Used in dentistry for denture bases.

resin, heat-curing,

n a resin that requires heat to activate its polymerization.

resin, inlay,

n an applied dental filling contained within the tooth and made up of natural or synthetic resin-based materials.

resin, quick cure,

n See resin, autopolymer.

resin, self-curing,

n See resin, autopolymer.

resin, thermoplastic,

n a synthetic resin that may be softened by heat and hardened by cooling.

resin, vinyl,

n an ethylene-derivative copolymer of vinyl chloride and vinyl acetate; used at one time for denture bases.
