Today, we have many choices of materials to fabricate a provisional crown and bridge.  We can choose from the traditional self-cured acrylic polymers, or the more advanced light-cured or dual-cured resins, as well as pre-fabricated provisional crowns.

Provisional materials can be categorized as follows:

  1. Bis-acrylic

    1. Dimethacrylate- identified as:

      1. bisphenol A-glycidyl methacrylate (BIS-GMA)

      2. urethane dimethacrylate (UDMA)

  2. Acrylics

    1. Methal Methacrylate (MMA)

    2. Ethyl Methacrylate (EMA)

    3. Polymethyl methacrylate (PMMA)

    4. Polyethyl methacrylate (PEMA)

  3. Pre-Fabricated

    1. Metal (Ion)

      1. stainless steel

      2. aluminum

      3. anodized gold

      4. tin

      5. tin-silver

    2. Polycarbonate

    3. Light-cured methacrylate composite crown

There are many advantages and disadvantages to each of these common materials.  You should thoroughly investigate the brands you are interested in before you discuss using a new material with your dentist.  Be ready to discuss the pros and cons of using different materials and /or techniques.
