Sprue Design and Its Effect on the Castability and Porosity of Titanium RemovablePartial Denture Frameworks

摘要

The use of titanium in dentistry has expanded steadily over the past thirtyyears. Many properties of titanium make it an ideal restorative material. Titanium has excellent corrosion resistance, fatigue resistance and biocompatibility. In addition, it has a low weight-to-volume ratio and a high strength-to-weight ratio. The primary dental application of this metal has been in the area of implantology. Recent advances in dental titanium casting machines allow for the use of titanium for crowns, fixed partial dentures, and removable partial denture frameworks.
