[Follow-up examination of maxillary orthopedically treated patients from functional aspects]

In order to check the efficiency of orthodontic therapy a clinical examination and model analysis were done in patients in a two-year-interval. The individuals were a part of different longitudinal group --patients after treatment with removable appliances, --patients after premolar extraction, --control group. The results show that functional disturbances can be observed earlier and more frequently in patients after extraction therapy. With advancing years the difference of functional disturbances between the groups becomes smaller.
