Abstract:   (6994 Views)

Background & Aim: The bonding potential of porcelain laminate veneers to enamel is usually provided. This study was designed to assess the bond strength of these veneers using Acid etch, saline or sandblasting technique.

Methods & Materials: In this study, 30 disks of porcelain (2.4 mm thickness and 9.5 mm diameter)were provided to measure the bond strength between laminate and resin. An initial preparation of one of the porcelain disk surfaces was carried out using one of the following techniques: group 1 acid etch-silane, group 2 acids etch and group 3 sandblasting. A composite disk was then shaped and cured to each porcelain disk. Then maximum force needed was measured to break the bond between composite and porcelain.

Results: Results showed that maximum bond was between composite and porcelain in acid etch-silane techniques while the least was in sandblasting technique. Analysis of variance showed no significant difference between group 1 and 2, with a significant difference between groups 1 and 3, 2 and 3.

Conclusion: There seems to be an advantage of combined use of acid etch-saline use prior to the application of bond in porcelain veneer restoration strength.
