What You Didn’t Know About Dental Crowns: Part III

DmolePerhaps you didn’t know that there was so much to know about dental crowns but we’re not finished yet. There is so much involved in dentistry including behind the scenes research studies, trials, and technological and material designs and inventions. All of it is to benefit the dental patient by making appointments shorter; procedures faster, easier and less invasive; and materials more durable and longer lasting. For instance, the raw materials utilized in dental treatments must be biocompatible, safe, strong enough to withstand the forces of chewing, as well as able to withstand moist environments.

Raw Materials

There are several materials involved in certain dental treatments such as dental crowns. Crowns require:

  • Plaster to create the mold
  • Material to make the crown such as plastic, ceramic, or metal
  • Adhesive cements to bond the crown into place
  • Surface coatings for esthetics


Different types of dental plasters are used for different reasons. Dental molds are made of plaster which is a mix of gypsum powder and water.  Dental impressions are made of plaster and record the shape of the teeth.  Model plaster is used to make models of the oral cavity. Investment plaster is used to make the molds that shape the metal, plastic, or ceramic.

Crown Fabrication

Impression plaster is used to make an impression of the tooth after it has been prepared for the crown. An investment mold is made by pouring investment plaster into the impression mold. The crown is then fabricated by pouring the chosen crown material into the investment mold which is heated up, cured, and hardened. The mold is then cooled, broken apart, and the crown is removed and ready to be placed.
