Smart orthodontic brackets
Force sensor – Torque sensor – Fixed orthodontic appliance – Braces – Bracket – Telemetry – Mechanical stress - Microcoil
Competence
In collaboration with the Department of Orthodontics, University of Ulm (Prof. Dr. B. Lapatki) and Hüttinger-Chair of Microelectronics (Prof. Dr. Y. Manoli) we develop new microsystems solutions for orthodontics. In the case of smart brackets, we integrate CMOS sensor chips in fixed orthodontic appliances able to provide the othodontics with objective information about the mechanical state of the appliance. The sensor systems enable the measurement of the six components of the force and moment vectors acting on each tooth of the dentition during orthodontic treatment. Our research group focuses on novel components for stress sensing, sensor system integration, and assembly and packaging technologies. Finally, we contribute the development of coils for telemetric energy and data transmission as well as the engineering of calibration equipment for the new systems. |
