Optional Module

with virtual articulator to explain functional occlusion:

The principles of occlusion, articulation and functional jaw movements are difficult to convey with just images and paper. 

The KaVo Virtual Articulator guides the student through the occlusal plane.

The relationships between occlusion can be clearly shown by simulating jaw movement and interaction with the antagonist with different adjusted angles of the condyle path inclination. 

At the same time, targeted cuts can be made through contact areas of particular interest, e.g. through canine guidance.

The virtual construction of different types of restorations can be clearly demonstrated. For support, contact areas and distances can be automatically marked with a colour scheme. 

At the same time, dynamic contact zones can be visualised; here, the canine guidance in a laterotrusion to the left.

Optional module "MasterPREP" – library with master preparations

Examples of different types of preparations, mostly showing pulps:
