Effect of the combined zirconium dioxide surface treatment on the shear bond strength of a veneering ceramic to zirconium dioxide

effect of four methods of surface treatment on shear bond strength of orthodontic brackets to zirconium

o bjectives: providing reliable attachment between bracket base and zirconia surface is a prerequisite for exertion of orthodontic force. the purpose of the present study was to eval- uate the effect of four zirconium surface treatment methods on shear bond strength (sbs) of orthodontic brackets. mat erials and methods: one block of zirconium was trimmed into four zirconium sur- faces, which se...

Effect of Four Methods of Surface Treatment on Shear Bond Strength of Orthodontic Brackets to Zirconium

OBJECTIVES Providing reliable attachment between bracket base and zirconia surface is a prerequisite for exertion of orthodontic force. The purpose of the present study was to evaluate the effect of four zirconium surface treatment methods on shear bond strength (SBS) of orthodontic brackets. MATERIALS AND METHODS One block of zirconium was trimmed into four zirconium surfaces, which served a...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Chipping of Veneering Ceramics in Zirconium Dioxide Fixed Dental Prosthesis

surface charge properties of zirconium dioxide

zirconium dioxide, commonly known as zirconia, is an interesting material and is receiving growing attention due to its excellent mechanical properties. the solid was characterized for surface area measurements, scanningelectron microscopy (sem), energy dispersive x-ray diffractometry (edx) and potentiometric titrations. surface titrations were carried out at the temperature range 303 to 323k i...
