DENTAL TITANIUM CASTING AT BAYLOR COLLEGE OF DENTISTRY - UPDATE

摘要

In 2001, we presented the results of properties testing relevant to dental applications for experimental binary titanium alloys with Ag, Co, Cr, Cu, Fe, Mn or Pd. Tensile strengths, casting performance, grindability, wear resistance, electrochemical behavior and biocompatibility were examined. During the last 5 years, we have tested more titanium alloys, including some ternary alloys, in search of good candidate alloys for dental prosthetic use. Of particular interest was the effect of Cu at improving the grindability and wear resistance, and the strengths of some alloys. Cu was added to alloys such as Ti-Si and Ti-Al alloys to test its effectiveness. In addition to the above characteristics tested, we also evaluated the fatigue resistance, fracture toughness and CAD/CAM applications of selected alloys. The most recent results of our properties characterization of candidate titanium casting alloys for dental prostheses are summarized.
