Abstract

CerAdapt (Nobel Biocare), the ceramic abutment made from densely sinterd high-purity aluminium oxide, was developed for single unit implant restoration with good esthetics and biocompatibility. However, there have been few clinical reports in the literature about surface treatment and bond strength of CerAdapt.<BR>The purpose of this study was to evaluate influence of various surface treatments on CerAdapt for shear bond strength of IPS Empress (IVOCLAR) cemented with Variolink II (VIVADENT). The surfaces of CerAdapt were treated by sandblasting with aluminium oxide for 10 seconds, 37% phosphoric acid for 60 seconds and 5% hydrofluoric acid for 60 or 120 seconds. As a control, the surface was not treated. Shear bond test was carried out with Instron 5567 (Instron Japan) at a cross-head speed of 1.0 mm/min.<BR>The results were as follows:<BR>1. The highest bond strength was obtained with sandblasting (20.8±1.85 MPa).<BR>2. The treatment with 5%hydrofluoric acid for 120 seconds (11.4±1.14 MPa) significantly decreased the bond strength of control (13.6±1.62 MPa).
