Chewing Simulator CS-4.8

8 stations for maximum efficiency

 

Applications

The device simulates various chewing movements in the mouth for materials testing of implants, bridges, crowns, composite material and jaw models:

 

• Execution of complete chewing cycles by means of linear 2-axis motion

 

• Interpolated circular dual-axis movement for higher simulation frequencies up to 5Hz

 

• Simulation of Bruxism especially to test bite splints

 

• New: Integrated real-time wear analysis with break detection for every sample station (option)

  

The functional principle of the CS-4 device set standards in pre-clinical screening of material since 1998 but could be further improved and adapted to our customers' wishes:

• Kinematics: Particularly precise motion through the use of digital servo drives
• Significantly  reduced noise when running, so can be used without problems in laboratories
• 2-axis operation reduces test times by up to 20% by means of simultaneous reverse motion along both axes
• Devices available which have identical specifications but 2 or 4 specimen chambers. This gives significant price advantages for users with smaller specimen volumes
•Various specimen holders, antagonists and special test rigs are available


Functional principle

An antagonist strikes a specimen in accordance with defined parameters. The loading force is produced directly by precise weights, and is transferred to the specimen. The same load values operate in all the chambers. The use of a modern motion controller allows a whole variety of motion patterns to be programmed. This initially enables the user to programme freely definable movements in both axes using the application software which is included. This allows for example the antagonist to be set to strike at minimal speed so as to reduce to a minimum the forces transferred to the specimens.

The weights are freely mounted on a traverse which is raised or lowered by a servo motor. The traverse connects all the weights together so that the kinematics are identical for all antagonists, with the aim of producing comparable results. As a result of the free mounting of the weights, at the moment when the antagonist strikes the specimen only the force of the weights operates - without any losses and clearly defined. This allows a particularly precise and realistic simulation of the chewing process.

The strike speed is adjustable in such a way that a defined momentum which culminates in a defined peak force is fed into the specimen.  

The chewing simulation in line with this procedure constitutes a standard which is applied on a worldwide basis in universities, dental clinics and by manufacturers.

Key Details

  • The technology is recognised and proven on a worldwide basis.
  • Continuous operation is possible for long duration tests due to the robust construction and use of high-quality components.
  • High degree of reproducibility of the results: the construction used ensures identical kinematic conditions in each specimen chamber
  • Excellent kinematics due to directly coupled servo motors in both axes
  • The specimen chambers can be used either with or without water fill.
  • Various designs available (2, 4 or 8 tests chambers, thermo-cycling, force measuring system)
  • Especially compact construction with a high level of rigidity
