Abstract
BACKGROUND: Orthodontic treatment for open bite and crossbite cases is always challenging. In this paper, we demonstrate a skeletal class III patient with anterior open bite and crossbite whose problem was successfully corrected with improved super-elastic Ti-Ni alloy wire (ISW). CASE SUMMARY: A 19 years old male came to our clinic with a chief complaint of anterior open bite and crossbite and not able to chew food well. Clinical examination revealed an angle class III malocclusion with anterior open bite, crossbite and spaced arch. Radiographic and clinical examination showed a skeletal class III pattern. We used ISW to level the upper and lower arch and to correct the anterior open bite and crossbite. Intermaxillary elastics were also used to achieve a better interdigitation. Finally, adequate overbite, overjet and a desirable occlusion were achieved. The active treatment time took 2 years and 2 months. CONCLUSION: In a case of class III angular malocclusion with open bite and crossbite in the anterior teeth, ideal results were achieved using the ISW technique and the patient was satisfied with the outcome.
