Non-surgical treatment includes muscle excersizes, medication when indicated, and mechanical treatment which aim at providing correct occlusial relations. Splints (thin transparent molds) are made individually. They relieve the symptoms and show the necessity of adjustment and reorganizing of occlusion.
