Fracture Resistance and Surface Treatment of Y-tzp Prepable Ceramic Abutments and Bars
NIMET DIAMOND ADATIA Fracture Resistance And Surface Treatment Of Y-TZP Prepable Ceramic Abutments and Bars. (Under the direction of Dr. Stephen Bayne) Intraoral preparation of zirconia implant abutments creates deep surface defects making abutments susceptible to fracture during loading. Fracture strengths were tested for (1) HIP-processed zirconia bars (Astra-Tech) after preparation and/or su...
متن کاملBonding of Y-TZP to dentin: effects of Y-TZP surface conditioning, resin cement type, and aging.
PURPOSE To evaluate the effects of two surface treatments, aging, and two resin cements on shear bond strength between dentin and yttrium-stabilized tetragonal zirconia polycrystal ceramic (Y-TZP). MATERIALS AND METHODS Eighty human molars were embedded in acrylic resin and sectioned 3 mm below the occlusal plane. These teeth and 80 cylindrical Y-TZP specimens (height, 4 mm; diameter, 3.4 mm)...
متن کاملPre-sintered Y-TZP sandblasting: effect on surface roughness, phase transformation, and Y-TZP/veneer bond strength
OBJECTIVES. Sandblasting is a common method to try to improve the Y-TZP/veneer bond strength of dental prostheses, however, it may put stress on zirconia surfaces and could accelerate the t→m phase transformation. Y-TZP sandblasting before sintering could be an alternative to improve surface roughness and bonding strength of veneering ceramic. The aim of this study was to analyze the effect of ...
متن کاملTooth surface treatment strategies for adhesive cementation
PURPOSE The aim of this study was to evaluate the effect of tooth surface pre-treatment steps on shear bond strength, which is essential for understanding the adhesive cementation process. MATERIALS AND METHODS Shear bond strengths of different cements with various tooth surface treatments (none, etching, priming, or etching and priming) on enamel and dentin of human teeth were measured using...
