The ultimate goal for an esthetic rehabilitation is the restoration of health, beauty, and function to the patient. This article illustrates a predictable system to guide the clinician with tooth preparations for porcelain veneer restorations based upon the additive diagnostic wax-up. This system promotes a preparation technique using a series of guides that direct the clinician to reduce only ...

This clinical report describes the fabrication and bonding of porcelain laminate veneer restorations in a patient with anterior open spaces. Laminate veneer restorations made of feldspathic porcelain were etched with 5% hydrofluoric acid, rinsed under tap water, ultrasonically cleaned with methanol, and primed with a chemically activated three-liquid silane bonding agent (Clearfil Porcelain Bon...

This report describes the bonding technique and clinical course of porcelain laminate veneer restorations applied to discolored maxillary incisors and canines. The patient was an 18-year-old woman, and tooth reduction was limited to the enamel. Laminate veneer restorations were made with a feldspathic porcelain material (Cosmotech Porcelain). After try-in, enamel surfaces were etched with 65% p...

OBJECTIVES Based on a maxillary premolar restored with laminate veneer and using the 3-D finite element analysis (FEA) and μCT data, the aim of this study was to evaluate the influence of different types of buccal cusp reduction on the stress distribution in the porcelain laminate veneer and in the resin luting cement layer. METHODS Two 3-D FEA models (M) of a maxillary premolar were built fr...

Veneering ceramics designed to be used with modern zirconia framework restorations have been reported to fracture occasionally in vivo. The fracture toughness of such veneering ceramics was measured and compared to that of conventional feldspathic porcelain veneering ceramics for metal framework restorations. The fracture toughness of the leucite free veneer was measured to be 0.73 MPa m ± 0.02...

BACKGROUND AND OBJECTIVES The removal of porcelain veneers using Er:YAG lasers has not been previously described in the scientific literature. This study was designed to systematically investigate the efficacy of an Er:YAG laser on veneer debonding, possibly without damage to the underlying tooth, and preservation of the veneer integrity. STUDY DESIGN/MATERIALS AND METHODS The Fourier Transfo...

This article presents a technique for the fabrication of provisional veneers when a single full-coverage anterior restoration is involved. A case that includes seven porcelain veneers and one all-ceramic crown is discussed.

STATEMENT OF PROBLEM Bonded porcelain veneers are widely used esthetic restorations. High success and survival rates have been reported, but failures do occur. Fractures are the commonest failure mode. Minimally invasive or thin veneers have gained popularity. Increased enamel and porcelain thickness improve the strength of veneers bonded to enamel, but less is known about dentin or mixed subst...

Objective:This study investigated the cervicalmicroleakage between titanium and three porcelain systems. Material andMethods:The titanium used in this study (commercially pure, grade 2, IMNR Bucharest, Romania) was veneered with three porcelain systems specially designed for fusing on titanium: Ti22 (Noritake, Nishikamogun, Aichi, Japan), Triceram (Esprident, Ispringen, Germany) andVitatitanker...
