Abstract

OBJECTIVES: Postoperative cracking and resultant failure of porcelain laminate veneer (PLV) restorations are considered a possible consequence of thermal variations that the restoration is likely to encounter 'in service'. The purpose of the study was to examine the impact of thermocycling on the development of surface flaws on the 'fit' surface of PLV restorations. METHODS: Sets of 30 Vitadur-Alpha dentin porcelain discs (15 mm diameter, 0.9 mm thickness) were thermocycled on the glazed and unglazed surfaces at three different temperature regimes to simulate the conditions encountered in service. Mean fracture strengths, standard deviations and associated Weibull Moduli (m) were determined using bi-axial fracture (ball-on-ring). RESULTS: The student-t-test analysis revealed a significant difference (P
