Ceramics are classified according to their base, silicate or oxide, the latter being either aluminum or zirconium oxide (2).
Resin cements are currently indicated for cementing ceramic restorations (3-6).
These restorations require an internal treatment according to their ceramic composition in order to optimize the ceramic-cement bond (1,7).
Results: Dual-polymerizing cements provided better adhesion values (11.7 MPa) than the autopolymerizing (7.47 MPa) (p-value M-WContinued development in ceramic materials has allowed the restorative dentist to extend their indications for use.
These materials can now be used for single or multiple bonded ceramic restorations, dental implants and implant abutments among others (1).
OBJECTIVES: The aim of this study was to evaluate bond strengths of zirconium-oxide (zirconia) ceramic and a selection of different composite resin cements.
STUDY DESIGN: 130 Lava TM cylinders were fabricated.
One hundred thirty composite cement cylinders, comprising two dual-polymerizing (Variolink II and Panavia F) and two autopolymerizing (Rely X and Multilink) resins were bonded to the ceramic samples.
Given the large number of combinations, Bonferroni correction was applied (α=0.001).
RESULTS: Dual-polymerizing cements provided better adhesion values (11.7 MPa) than the autopolymerizing (7.47 MPa) (p-value M-W Occlusion and Prosthodontic Teaching Unit Department of Stomatology University of Valencia Edificio Clínica Odontológica C/ Gascó Oliag Nº1, 46010 Valencia, Spain , E-mail: [email protected] This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
