Camouflage Treatment of Skeletal Anterior Open Bite with Tongue Training

Abstract

The aim of this case report was to present an adult patient who suffered from poor occlusal function and poor aesthetic appearance due to skeletal anterior open bite. After orthodontic treatment, she was satisfied with improvements of mastication and esthetics. A case of 20-year-old female with skeletal Class II jaw relationship, mandible retrognathism and anterior open bite without signs and symptoms of temporomandibular disorder. Intraoral examination showed premature contact over bilateral posterior teeth and the forward resting position of tongue. Our treatment plan was orthodontic camouflage with extraction of all first premolars and tongue training. As forward resting position of tongue was noted, a tongue crib soldered on molar bands was used and the patient was instructed with tongue exercises. Normal overbite and overjet were achieved within four years of treatment. Her profile became more harmony after correction of anterior open bite. Although the stability of occlusion relies on the position of tongue, the current masticatory and facial profile provide a better quality of life. Orthodontic treatment of skeletal anterior open bite should be very careful. Appropriate diagnosis, differentiation of etiology and proper selection of mechanics must be verified before initiating treatment.
