Dental composite application
Dental composite-A highly cross-linked polymeric material reinforced by a dispersion of amorphous silica, glass, crystalline, or organic
resin filler particles and/or short fibers bonded to the matrix by a coupling agent. Depth of cure-The thickness of a resin that can be converted from a monomer to a polymer under a specific light-curing condition. Dual-cure resin-A dental that contains both chemically activated and light- activated components to initiate polymerization anti potentially overcome the limitations of the chemical cure or light-cure systems, which include porosity incorporated during mixing and limits on depth occure, respectively. Estrogenicity-The potential of synthetic chemicals with a binding affinity for estrogen Iecptors to cause reproductive alterations. Filler-The inorganic antllor organic resin particles that arc designed to strength a composite, therease thermal expansion, minimize polymerization shrinkage, ant1 rctiuce the amount of swelling caused by water sorption.
Flowable composite-A hybrid composite with reduced filler level and a more narrow particle size distribution that increases flow and promotes intimate adaptation to prepared tooth surfaces.
Hybrid composite-A particle-filled resin that contains a graded blend of small and colloidal silica filler particles to achieve an optimal balance among the properties of strength, polymerization shrinkage, wear resistance, and polish ability.
Inhibitor-A chemical added to resin systems to provide increased working time and extended storage life by minimizing spontaneous polymerization. Initiator-A free radical-forming chemical used to start the polymerization reaction. It enters into the chemical reaction and becomes part of the final polymer compound; thus it is not a catalyst.
Light-cured composite-A particle-filled resin consisting of J. single paste that becomes poly- mcrizetl through the use of a photosensitive initiator system (C(2 anti an nniinc initiator) and a light source activator (visible hlue light).
Microfiller-Colloitla silici filler particles, approximately 0.04 ym in size, which reinforce resin materials an0 form a coniposite that can be polished to a highly smooth surface. Oxygen-inhibited
layer-Ttic thin surface region of a polymerized resin that contains unreacted methoacrylate groups associated with exposure to oxygen. Packable composite-A hybrid resin composite designed for use in posterior arras, where a stiffer consistency facilitates condensation in posterior teeth
