Dental prostheses of Ti are normally cast in pure Ti. Some appliances, however, require higher yield strength. Casting of Ti alloys is of interest in such cases. The objective of the present work was to study the quality of castings made of Ti-6Al-4V compared with those made of pure Ti.
Three brands of dental ceramics for veneering to titanium: TitanBond (O’Hara), Ti-Ceram (Ducera) and Titankeramik (Vita) were tested to compare their fracture properties in wet and in dry conditions.
The aim of this work was to study mold filling during casting of standardized five-unit Ti bridges vs. the gas permeability of the investments.
