coefficient of thermal expansion

The change in the dimensions of a material when its temperature is raised 1°C. In dentistry, if the relative expansion and contraction of restorative materials, casts, or appliances are not accounted for, the patient may have problems with improper fitting, microleakage, or adhesive debonding.
