Objectives: Porcelain veneers are steadily increasing in popularity among today’s dental practitioners for conservative restoration of unaesthetic anterior teeth. As with any new procedure, in vitro and in vivo investigations are required to assess the ultimate clinical efficacy of these restorations. The current literature was therefore reviewed in search for the most important parameters dete...

Background and Aim: Discoloration is a major concern with regard to the use of tooth-colored restorations. Type of restorative material and surface treatment are believed to play a role in this regard. This study sought to compare the color change of glazed and polished dental porcelain after 30 days of immersion in chlorhexidine (CHX). Materials and Methods: In this in vitro, experimental s...

objective: zirconia cores have limited light transmittance and data are scarce on light transmission through zirconia cores with and without the veneering ceramic.   methods: in this in vitro study, disc-shaped specimens (11.5 mm in diameter and 0.4 (0.05) mm in thickness) were fabricated of three types of zirconia namely mamut, heany and zirkonzahn (n=5). a disc-shaped specimen (11.5 mm in dia...

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.

introduction: failures might occur at metal‒porcelain interfaces as a problem with metal‒ceramic restorations even with the application of airborne-particle abrasion technique. this study was undertaken to evaluate the effect of nd:yag laser treatment on the bond strength of porcelain fused to metal. methods:  twenty-four cylindrical specimens (4 mm in diameter and 4 mm in height) were made of ...

The heat treatment of dental alloys prior to porcelain application/veneering has been proposed as a way ensure sufficient oxide scale and promote the porcelain’s adherence in porcelain-fused-to-metal (PFM) fixed prostheses. present study investigates relationship between bond strength selective-laser-melted (SLM) titanium temperature titanium’s pre-oxidation. SLM Ti-6Al-4V substrates were airbo...

Porcelain laminate veneers have been a common treatment strategy in dental clinics. It is a conservative method for treatment of esthetic and functional problems in anterior region of oral cavity. Wide range of dental ceramics is now available on market for fabrication of laminate veneers. Clinician should have enough knowledge regarding the composition and properties of these materials in orde...

For dental porcelain, precise shade matching of tooth coloured restoration with the adjacent dentition is deemed necessary. However the colour instability in porcelain restoration is a common problem now a day’s particularly when they exposed to routinely consumable beverages which sever its nature of being tooth coloured. Therefore in this concern the authors has tried to emphasize the histori...

With the increasingly commercial emphasis on dental esthetics, patients have become more interested in improving the appearance of their smile. For many, whiter teeth is their chief goal. However, when considering dental bleaching, practitioners need to take certain precautions. Over the past decade, multiple studies have evaluated the effects of bleaching agents on restorative materials. This ...
