EFFECT OF SURFACE TREATMENT METHODS ON SHEAR BOND STRENGTH OF RESIN MATRIX CERAMICS

Abstract

Today dentistry, all ceramic systems are the most commonly used restoration material. With the developments in CAD/CAM systems, the material variety and usage areas of all ceramics have expanded and is an alternative to metal-supported ceramics. Resin matrix ceramics aim to combine the advantages of two materials that are frequently preferred in direct and indirect restorations. These materials have advantages such as easy workability, good marginal fit, high mechanical resistance and repairability. Successful bonding is necessary for a successful restoration in all ceramics. Adhesive bonding is recommended for resin matrix ceramics. The success of the adhesive bonding depends on the knowledge and skills of the practicing clinician, the isolation conditions, the correct material selection, and the necessary surface preparations before cementation. Surface treatment applications increase the bond strength values considerably. These surface treatments could be mechanical, chemical or both mechanical and chemical. Surface treatment applications should be selected in accordance with the material content. Before cementation, surface treatment and silane application are recommended for resin matrix ceramics.
