• Problems on Titanium Castings for Clinical Use.

抄録

Although titanium has been a popular metal in dentistry, it was not actively applied in the clinic. Some of the reason were most importantly a hardened layer formed on the casting surface with a reaction between mold material and molten titanium that had different physical and chemical properties than titanium. Moreover, fit of prostheses is lost due to the removal of the reacted layer. On the other hand, internal defects are often observed by X-ray photography of titanium castings. Bubble-like defects formed by gas inclusion will lead to worse durability.<BR>In order to obtain sound titanium castings, it is important to maintain surface transcription with high quality during the casting procedure and decrease casting error. A new investment may be a key to success. A development of titanium alloy seemed to be effective as prosthetic materials.
