摘要：

A three-dimensional finite element model of a human premolar with a composite resin Class Pi MOD has been used to investigate the temperature changes and induced thermal stresses associated with the imbibing of a hot liquid. Regions of high tensile stress were revealed and their possible clinical significance with respect to microleakage and failure in the approximal region of the restoration are discussed.
