Abstract

OBJECTIVES: The purpose of the current study was to examine whether alumina abrasion regime influenced the necessary surface roughness conducive to mechanical interlocking prior to composite resin bonding. The impact of alumina abrasion and cement lute on the bi-axial flexure strength and associated Weibull Moduli (m) on the cemented surfaces of disc specimens of porcelain laminate veneer (PLV) materials was therefore investigated. METHODS: Sets of 20 Vitadur-alpha dentine porcelain discs (15 mm diameter, 1.7 mm thickness) were condensed and prepared by abrading with 25, 50 or 110 microm alumina. Further specimen groups were stored wet or coated with a resin cement. Mean fracture strengths, standard deviations and associated m were determined using a ball-on-ring assembly. The surface roughness was assessed using profilometry and scanning electron microscopy. RESULTS: The one-way ANOVA revealed a significant reduction (P
