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 : marginal adaptation is important for long-term success of full-coverage restorations. the aim of this study was to determine the effect of porcelain firing cycle and different thicknesses of ips e.max core on marginal accuracy of all-ceramic restorations. materials and methods : a standard stainless steel die with 0.8 mm classic chamfer finish line and 10° taper was used in this in...

anterior teeth, reestablishing smile harmony, using feldspathic porcelain veneers. Results of clinical follow up after 36 months are also presented. The advantages, disadvantages and limitations of the technique are detailed with reference to the relevant literature. This suggests that the success of treatment depends on adequate conditions of bonding between the veneers and the tooth complex, ...

Many different materials and treatment options are available in esthetic and restorative dentistry. Various newer products, such as pressed ceramics, offer enhanced functionality; however, in thinner dimensions, they lack the inherent esthetic beauty of traditional materials such as feldspathic porcelain. As patient demands for better esthetics have increased in recent years, so too has the nee...

Aims: The aim of this study was to investigate the effect of flowable composite, as an intermediate layer between feldspathic porcelain and composite, on bond strength during intra-oral porcelain repair and its potential role in providing a long-lasting repair. Methods: Forty feldspathic porcelain (VMK 95) specimens were fired in metal ingots. They were airborne-particle abraded, etched with 4%...

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...

A new esthetic solution to restore dental implants in combination with limited interdental, facial or labial, or interocclusal space is presented. This article describes the translational application of novel-design porcelain veneers and adhesive restorative principles in the implant realm. A patient is presented who was treated with a single implant-supported restoration replacing a missing ma...

Introduction: Porcelain fracture is a relatively common problem in clinical dental practice. Various methods have been proposed for repairing porcelain fractures including direct composite resin repair or construction of a porcelain laminate veneer and its cementation with a resin cement. Evaluation of shear bond strength of porcelain repair methods was the purpose of this study. Methods: Tw...

in this study, porcelain bond strength to three different alloys of gold-base, pd-ag and base-metal were compared and the effect of repeated porcelain sintering on bond strength was evaluated. the obtained results showed best bond strength of porcelain with gold-base alloy. pd-ag and base-metal alloys showed less strength respectively. during repeated sintering of porcelain, bond strength has n...

In this study, an Co/Fe coated porcelain using a cobalt and ferrous sulfate was sintered at 1,250 °C. The specimens were investigated by HR-XRD, FE-SEM (EDS), Dilatometer, UV-vis spectrophotometer. surface of the uniformly fused with pigment, white ware celadon body densely to certain thickness from surface. Other new compounds produced chemical reaction cobalt/ferrous during sintering process....
