Shear bond strength of a hot pressed Au-Pd-Pt alloy-porcelain dental composite.
OBJECTIVES The purpose of this study was to evaluate the effect of hot pressing on the shear bond strength of a Au-Pt-Pd alloy-porcelain composite. METHODS Several metal-porcelain composites specimens were produced by two different routes: conventional porcelain fused to metal (PFM) and hot pressing. In the latter case, porcelain was hot pressed onto a polished surface (PPPS) as well as a rou...
متن کاملTarnish resistance evaluation of experimental Pd-free Ag-Au-Pt-Cu dental alloys.
This study evaluated the tarnish resistance of eight experimental Pd-free Ag-Au-Pt-Cu dental alloys in a 0.1% Na(2)S aqueous solution at 37 degrees C. Color measurements of the plate samples were made using a computerized spectrophotometer before and after immersion in the test solution for up to 72 hours. Tarnish discoloration was evaluated using the color difference vector, DeltaE*, in the CI...

PURPOSE The aim of this study was to investigate the cytotoxicity in human gingival fibroblast by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and corrosion behavior by potentiodynamic polarization technique of commercially pure titanium (Ti 12) and its alloy Ti-6Al-4V (Ti 31). MATERIALS AND METHODS In the present in vitro study, cytotoxicity of Ti 12 and Ti 31 in ...
متن کاملMaintenance of Dental Implants: A Review
Objective: Successful bonding of a dental implant to bone, which was referred to as osseointegration by Branemark has been well documented. However, long-term prognosis of an implant depends on adequate maintenance and long-term care. An effective maintenance program is required to preserve the health of peri-implant tissues. Several techniques have been suggested for this purpose but it is n...
