Toothbrush simulation

Devices with 4, 8 or 12 test stations for every application

Simulates various brush movements

The device simulates various brushing movements on the surfaces of teeth and material specimen.

Functional principle

A maximum of 4/8/12 specimen are simultaneously exposed to abrasion in the tooth brushing machine. Each specimen may be different in form and material (hardness), and may be loaded with various levels of contact pressure. The specimen chambers are separated from each other so that each specimen can be operated with its own liquid (e.g. toothpaste-water mix), and individually cleaned. 
All the brushes are controlled by a central drive system, and the chosen type of movement is therefore the same for all specimens used in the test. A high-grade motion controller guarantees exact speeds and trajectories which can be adjusted with a very high degree of precision. The motion sequence (teeth cleaning technique) can be freely selected from a combination of forwards, backwards and circular movements. Complex motion sequences can be easily programmed by means of an optional software module.
