It had been reported that the orthodontic treatment of skeletal Class III openbite with tongue thrusting were very difficult and complexity, by reasons of difficulty vertical tooth movement and occlusal stability in retention period.
We experienced the treatment above patient who was a 16-year-5-month old-female at the first examination with skeletal class III, unilateral congenital missing tooth (upper left side second bicuspid) and openbite with tongue thrusting. We planed appliances were multi-bracket system, expansion appliance and non-extraction method that is expanded maxillary arch in order to reduction of tongue thrusting, myofunctional theraphy (MFT) and non-extraction treatment were placed.
As a results of that, we obtained a favorable occlusion and still maintained in 2 years retention terms.
In this experience, it was suggested that the evasion of excessive oral capacity reduction for tongue thrusting and asymmetric molar occlusal relationship might be beneficial treatment ideas.
