Class III skeletal changes resulting from untreated forced bite – case report

There are many factors that contribute to the development of a skeletal Class III malocclusion. On the one hand, it can be inherited, on the other hand it can be caused by environmental factors. An abnormal, palatal course of the upper incisors eruption can lead to premature tooth contacts resulting in anterior functional displacement of the mandible. Such a condition at the developmental age can lead to the secondary skeletal malformations and can strengthen skeletal Class III. The key to therapeutic success is the early detection of functional abnormalities of the masticatory system which result from incorrect position of individual teeth, and quick orthodontic intervention involving an interceptive treatment. This paper describes the effects of overlooked developmental age-related dental anomalies that led to skeletal changes. Initially, an additional difficulty in treatment was poor co-operation with the patient resulting from strong dentophobia. Compensatory treatment using fixed appliances and arch-sliding mechanisms can provide effective therapy in such conditions. Thanks to the release of the maxilla, it was possible to use the residual growth potential of the patient to improve the sagittal skeletal relationship of bone bases, which in turn contributed to the improvement in the aesthetics of soft facial tissues.
