Abstract: A model for learning dentistry skills and including a shell attachable to a phantom head, through-holes disposed in the shell, teaching teeth individually arranged in the through-holes, and having a carrier plate attachable to the shell, such that a teaching tooth is releasably fixed on the shell and is adapted to be inserted into the model and removed therefrom. At least one peg disposed on the carrier plate, and a holding chamber disposed in the peg, wherein a holding element projects from each tooth and passes through a through-hole in the shell and is aligned with a holding chamber and is inserted into the holding chamber, and a holding strip disposed between the shell and the carrier plate and adapted to contours of the carrier plate and the shell and disposed in openings, the holding strip being movable for securing the holding element of the teaching tooth to the carrier plate.

Abstract: In an articulator (1) by means of which demonstration movements of a lower jaw model (8) can be undertaken and comprising a two-piece carrier frame (2) with an upper jaw model (7) attached to its locationally fixed top part (3) and the lower jaw model (8) attached to its bottom part (4) that can be pivoted to a limited extent about a horizontally running axis (shaft 5), the lower jaw model (8) is supported on the bottom part (4) of the carrier frame (2) by means of an adapter (11) and the adapter (11) is mounted in the bottom part (4) in a rotating arrangement. This embodiment makes it possible for different jaw models to be attached to the top part (3) and the bottom part without difficulty, without the need to undertake machining operations or to have technical knowledge. In addition, the two jaw models (7 and 8) can be aligned with one another without problems.
