STATEMENT OF PROBLEM The conservation of sound tooth structure helps preserve tooth vitality and reduce postoperative sensitivity. Innovative preparation designs, like those for porcelain laminate veneers, are much less invasive than conventional complete-coverage crown preparations. However, no study has quantified the amount of tooth structure removed during these preparations. PURPOSE The ...

STATEMENT OF THE PROBLEM Porcelain laminate veneer is an esthetic restoration used as an alternative to full veneer crowns and requires minimal tooth preparation. In restoration with porcelain laminate veneers, both the longevity of the laminate and conservation of the sound tooth structure are imperative. PURPOSE The present study aimed to investigate the shear bond strength of porcelain lam...

as well as by an increase in susceptibility to caries due to dissolution of the highly calcified prismless enamel by acid etching, or it could be attributed to reduced self-eleaning activity in the area around the bracket base. Recently, glass ionomer cement (GIC)iii-iS) has been used as an adhesive material for the purpose of enamel protection beeause no etching is required for application. Ho...

Aim: The difficulty of asking questions to each other during the appointment process with their doctor, long waiting times patients in rooms clinics, and fact that it is easier get medical information on internet due ongoing COVID-19 virus infection. Porcelain laminate veneers (PLVs) have been frequently used restore anterior teeth for nearly three decades, thanks aesthetic appeal, durability, ...

the major foible of dental ceramics is their brittle nature. therefore, the producers of these materials have focused on the “strength” issue. a method of increasing strength is ion exchange on porcelain surface which leads to formation of a compressive crust that opposing forces should overcome before developing a crack. in current study, ion exchange in two types of porcelain, ceramco ii whic...

During the past 25 years, there has been a lot of discussion regarding the preparation techniques used for porcelain veneers. Calamia and other early pioneers looked at veneers as a non-invasive, additive process and worked primarily with a nopreparation concept. Early on it was found that a little enamel preparation could help to enhance the esthetic outcome and improve the marginal fit. Later...
