ABSTRACT:
A teaching model for dental students includes an upper and a lower jaw each with removable artificial teeth which resemble natural teeth in their hardness and appearance. Each tooth has a crown portion, which extends above the gum line, and a root portion. The root portion is oval-shaped, in cross-section, and tapered along its axis to closely fit in an oval and tapered socket in the jaw. The jaw has open socket holes so that the root portions protrude through orifices in the bottom face of the jaw. Each tooth root portion has embedded therein a rotatable quarter-turn locking device whose locking head passes through the socket orifice and, when turned 90.degree., cams on the bottom face of the jaw to draw the tooth into its socket and thereby lock the tooth in position. A tooth is readily replaced by turning the locking head backwards 90.degree. to release the tooth.
