| 内容記述 | Dental prostheses are usually made by a casting process. Most currently available dental alloys are therefore developed to facilitate dental casting. Cutting and grinding of dental materials have been regarded as finishing processes rather than forming methods. Current CAD/CAM technology is a considerable advancement over conventional dental casting, and machining has become one of the important forming methods. However, few dental alloys have been developed for good machinability (ease of cutting or grinding). Titanium is widely known as an excellent biomaterial because of its superior biocompatibility and corrosion resistance, but it remains one of the most difficult dental materials to process. Some dental applications demand materials with high strength as well as improved machinability. To this end, in this study, experimental titanium alloys were developed for dental CAD/CAM systems. The alloying elements chosen were copper, silver, and gold from β-eutectoid elements and zirconium, niobium, and hafnium from β-isomorphous elements. Among the experimental binary titanium alloys tested, certain Ti-Ag alloys were found to provide both better machinability and higher strength compared to unalloyed titanium. The improved machinability could be attributed to the finely dispersed brittle second phase that reduces elongation. The Ti-Ag alloys showed both corrosion resistance comparable to unalloyed titanium and anti-biofilm characteristics with no bactericidal activity. The spontaneous formation of calcium phosphate on the alloys in simulated body fluid was also confirmed. Ti-Ag alloys are thus good candidates for use as machinable dental biomaterials. |
