This mass was diagnosed as benign hypertrophy of the masseter muscle, and the masticationary dysfunction was treated with jointguard, resin temporary crown, permanent crown and bridge. One year and two months after treatment the masticationary dysfunction almost disappeared and the hypertrophy of the left masseter muscle showed shrinking tendency.
