Thematik

The aim of the lectures is to acquire the knowledge of the anatomy and function of chewing apparatus. Students learn the types and use of articulators.

The aim of the practices is to learn the occlusal anatomy of the teeth, and to wax up the occlusal surfaces of premolar and molar teeth according to the technology of HC Lundeen in order the better understanding the occlusion and articulation movements. Students learn the types and use of articulators and face-bow.
