Configuration factor



 It has been suggested that this article or section be merged into dentistry. (Discuss)

In dentistry, the configuration factor (also known as c-factor) refers to the number of bonded to unbonded surfaces in a tooth preparation. For instance, in an occlusal class I preparation there would be 5 bonded surfaces and only 1 unbonded surface. The net result would be a C factor of 5. As the C factor increases so to does the possibility of bond disruption when using a composite resin. This effect is caused by a reduction in unbonded surfaces in which the composite can "flow" to relieve polymerization stress. The technique of incremental layering has been suggested to compensate for preparations with high configuration factors.
