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 !

Depends: Intraditional removable dentures base metals are mixed into an alloy...However, semiprecious alloys can be used as well. If you're asking about metal framework for implant retained, then typically a gold alloy. The acrylic is very similar to the acrylic used in nail salons for lengthning/strengthning nails.

Metal and acrylic: For removable partials which replace missing teeth the metal portion is chrome cobalt alloy, the plastic is acrylic. Some are all acrylic and flexible. There are various formulations of the acrylic by various dental labs. Unusual reactions to these materials are very rare.

There are a few...: Historically, removable partial and complete denture frames were composed of a gold alloy. This alloy has fallen out of favor due to its high cost. These days, the most popular casting alloys used for this purpose are chromium-cobalt alloys; the prototype was a proprietary product called "vitallium". This alloy combines strength, rigidity, resistance to corrosion, and bio-compatibility.

Chromium Cobalt: Chromium cobalt is a common metal used in the fabrication of removable partial dentures and reinforcement of full dentures. I have seen dentures that have used gold, but due to the expense of the materials, it is not that common any more.
