Objective:
To explore the influence of the type of occlusal splint on the masticatory muscles (TA,MM).
Methods:
TA and MM EMG during ICP maximal clenching were recorded in 20 dentate normal subjects, when they weared no occlusal splint, relaxation splint and mandibular stabilization splint.
Result:
With the insertion of relaxation splint and mandibular stabilization splint, the EMG parameters of TA and MM during ICP maximal clenching was dramatically reduced (P<0.05).
Conclusion:
The relaxation splint and mandibular stabilization splint can relax the masticatory muscles.
