| Popis: | Background This case report presents an invisible orthodontic treatment of a 26-year- old adult female patient with Class II deep bite with narrow mandibular arch. The patient did not wish to wear any visible appliances, so we selected the multilingual bracket appliance. Because she had a deep bite, it was impossible to place the multilingual bracket from the beginning of treatment. Methods We had to correct molar occlusion, expand the mandibular arch, upright the premolars and molars distally, and intrude mandibular incisors to correct the deep bite. After this process, we were able to place the lingual brackets in the maxillary arch. We extracted both maxillary first premolars to reduce crowding and to correct the overjet. The total active treatment period was 31 months. Results The amount of over bite and overjet was 1.5 and 1.5 mm, respectively. Overcorrection was achieved. Fixed retainer in the mandibular arch was used. Four years after the active treatment, the patient's occlusion is stable. Conclusion This is the first case report of an adult patient with Class II division 2 malocclusion using the multilingual bracket appliances. |
