Functional orthopaedics uses muscle forces in the treatment of malocclusion. But there are also some aberrant muscle forces called parafunctions and dysfunctions of the masticatory system. Orthodontic treatment with myotherapy, reeducation and habit-breaking appliances can eliminate them. Restoration of myofunctional balance is the basis of optimal growth, development of the face and correct jaw position. Indications for habit-breaking devices are the most often habits such as fingersucking, nailbiting, and dysfunctions: reverse swallowing pattern with tongue thrusting, hipotonic lips with oral breathing and speech problems. This article presents several removable appliances which are used in correction of above malfunctions/disorders particularly including a combined functional and tooth guidance appliance of a new generation called Pre-Orthodontic Trainer T4K. Moreover, a bionator, Fränkel appliance, lip bumper and a standard vestibular screen applying in prophylaxis and early orthodontic treatment is mentioned. (Clin. Exp. Med. Lett. 2006; 47(3):147-151)
