The Relationship between Chin Pressure and the Severity of TMD in Violin Players

This research aimed to determine the relationship between playing the violin and the severity of TMD and the maximum pressure on the chin rest within safe limits while playing the violin, to prevent TMD occurrence. The 20 violin players of OSUI Mahawaditra and MYSO orchestra were undergoing the examination and interview. Measurement of the pressure on the chin rest was done using a Flexi force device attached to the chin, which will measure the chin pressure on the instrument (N). The highest maximum pressure is 15.157 N, while the lowest maximum pressure is 0.126 N. The most elevated average pressure is 6.203 N, and the most moderate average pressure is 0.025 N. There is a strong relationship between chin pressure on the chin rest and TMD conditions in the violinist. There is no relationship between the frequency and duration of violin training with TMD conditions in violin players.
