چکیده
Porcelain enamel is an inorganic-type coating, which applied to metals or glass for both decorative and functional purposes. This coating a silica-based solidified mass obtained by high-temperature firing (temperature can range between 450 1200 °C depending on the substrate). coatings differ from ceramic mainly their structure dilatation coefficient, organic paints inorganic nature of matrix chemical bond that exists substrate.

Effect of porcelain and enamel thickness on porcelain veneer failure loads in vitro.
STATEMENT OF PROBLEM Bonded porcelain veneers are widely used esthetic restorations. Although high success and survival rates have been reported, failures occur. Fracture is the most common failure mode. Fractures range from incomplete cracks to the catastrophic. Minimally invasive or thin partial veneers have gained popularity. PURPOSE The aim of this study was to measure the influences of p...
متن کاملEnamel Thickness After Preparation of Tooth for Porcelain Laminate
OBJECTIVE In this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers. MATERIALS AND METHODS Part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. The teeth were imbedded in autopolimerize acry...
متن کاملOptical coherence tomography for evaluation of enamel and protective coatings.
Optical coherence tomography (OCT) is an interferometric imaging technique. This study aimed to employ OCT to evaluate four different resin-based materials including a coating containing glass-ionomer filler and calcium, a giomer, and two fluoride-releasing self-etch resins. The coating and its underlying and adjacent enamel were monitored using swept-source OCT (center wavelength: 1330 nm) at ...

متن کاملComparison of the microshear bond strength of feldspathic porcelain to enamel with three luting resins.
PURPOSE The purpose of this study was to compare microshear bond strength of three different luting resins using a new microshear method closely simulating clinical condition. METHODS Thirty 1-mm-thick slices of intact human first molars and thirty 0.8-mm-diameter feldspathic porcelain rods were etched by 37% phosphoric acid for enamels and 9.5% hydrofluoric acid for porcelains. Adhesive (Mar...
