Abstract :
This paper presents a tool for orthodontic research and education, namely an instrumented tooth enabling all six force and moment components exerted on the tooth to be measured. The mechanical load values are inferred from mechanical stress values measured at the surface of a CMOS stress sensor system sandwiched between two pins dimensioned as a tooth root. The resulting sensor module measures 11.6 mm in height and 3.5 mm in diameter. It allows the measurement of forces up to 60 N and moments up to 10 Ncm and thus covers the range of forces and moments relevant for orthodontics.
