Study Notes

Introduction to Composite Restorations

A composite is a physical mixture of two or more chemically different materials, with a resin as the matrix in resin composites.
The composition includes a matrix phase, inorganic filler, silane coupling agent, and photo-initiator.
Inorganic filler reduces polymerization shrinkage, improves mechanical properties, and provides aesthetic properties such as color and translucency.
Silane coupling agent provides interfacial bonding between the organic matrix and inorganic filler particles.
Photo-initiator, such as camphorquinone, is used to polymerize current composites with the help of light.
Composites can be classified based on filler particle types (homogeneous, heterogeneous, hybrid), polymerization method (self-cured, light-cured, dual-cured), and viscosity (packable, flowable).
Macrofill, midfill, microfill, hybrid, nanofill, packable, and flowable composites are different types of dental composites, each with their own unique properties and indications.
Polymerization shrinkage can be compensated through incremental insertion and curing technique, soft-start polymerization, and stress-breaking liners.
Light curing variables include curing equipment, intensity of light, and staged curing to minimize shrinkage stress.
Important properties of composites include linear coefficient of thermal expansion, isolation factors, and occlusal factors.
Composites have advantages such as esthetics, conservative cavity prep, and improved retention, but also have disadvantages such as gap formation and difficulty establishing proximal contour and contact.
Cavity prep for composite includes outline form, retention form, and resistance form, with beveling of enamel margins to improve bond strength and retention.
