What are the metals and acrylics used in partial dentures?

Inert metal, resin: Partial dentures are combination of nickel, cobalt molybdenum alloy for the metal and a polymer, monomer resin that is heat polymerized under pressure to make it rigid and dense. The teeth are also made of resin or ceramic. The materials are highly polished to make them impervious to stain and odors as well as smooth to the tongue. Over time, the polish erodes and materials deteriorate.

Many different: These days, there are many different acrylics. It depends upon the desired result and time expected to last. Whether immediate , temporary or long lasting. Also, the number of teeth being replaced and those remaining to support it. Most common is methylmethacrylate. The most common metal is primarily chrome cobalt with some others in small amounts. Vitallium is a trade name.

Depends on quality: The materials of the partial denture directly affect the cost and quality of the prosthesis. Inexpensive partial dentures are usually made with an inexpensive material called chrome colbalt. The better quality partials are made with vitallium, and even better, gold. Of course the cost is different. The acrylic used also makes a difference. Using a fibered acrylic adds more strength !
