Dimensional change of refractory materials used for ceramic veneers.
The current literature considers a number of clinical factors which affect the fit of all-ceramic laminate veneers. However, little consideration has been given to the refractory die materials, and the laboratory techniques used during the construction of these restorations. This study found a wide range of dimensional change occurred during setting and through six firing cycles, for seven refractories recommended for the construction of laminate veneers. It is therefore important that where patient treatment involves the use of veneers the clinician considers the suitability of the materials offered by the laboratory, in order to obtain the optimum marginal integrity.
