A mandibular typodont with some missing teeth to illustrate the "sockets" and screw holes with which the plastic teeth are held in the typodont.

In dentistry, a typodont is a model of the oral cavity, including teeth, gingiva, and the palate.

A typodont is an educational tool for dental and hygienist students, allowing them to practice certain dental procedures on the plastic teeth of a model before actually performing the procedures on live patients. Generally, typodonts have replaceable, screw-in teeth that are composed of materials that allow students to drill cavity preparations and fill them with restorative material, such as amalgam or composite, or prepare the plastic teeth for crowns and bridges.
