Medical Forum / General / Dentistry / February 2007New dental restorative materials
I just read article here http://www.swri.org/3pubs/ttoday/spring98/bite.htm Is this currently in operations? If you mean do dentists now have this material to use restoring teeth, the answer is no. Composite, amalgam, gold, and porcelain are all very good restorative materials. However none of them are perfect. I'm sure that better materials are under development, but it is a difficult challenge to find a material that is strong, bonds well, does not shrink, does not expand, is esthetic, and has other physical properties similar to tooth structure.

I was still in dental school at the time but I remember much talk about it. It was still taking me 2 hours to do an occlucal amalgam on a premolar. Did anyone on smd every use it? From what I recall, I think it was called Galloy and was really hard to carve once it sets up.

Hard to work with and it split teeth. Never saw any of it first hand. D Tried a sample on a relative...they want free care, then they have to be prepared to be a test dummy...didn't like the handling properties, and didn't like finished result. I replaced it less than a year later and it seemed soft when removing. Odd?!?

To my knowledge, there is no material like this ready for marketing. Looks interesting though--thanks for posting.
