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).
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.
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.
开颌和反颌病例的正畸治疗一直具有挑战性。在本文中,我们展示了一名骨性III类患者,其患有前牙开颌和反颌,通过改良的超弹性钛镍合金丝(ISW)成功矫正了问题。
一名19岁男性因前牙开颌和反颌且咀嚼食物困难为主诉前来我院就诊。临床检查发现为安氏III类错颌,伴有前牙开颌、反颌和牙弓间隙。影像学和临床检查显示为骨性III类错颌。我们使用ISW整平上下牙弓并矫正前牙开颌和反颌。还使用了颌间弹力牵引以实现更好的牙尖交错。最终,获得了足够的覆颌、覆盖和理想的咬合关系。主动治疗时间为2年2个月。
对于前牙开颌和反颌的III类安氏错颌病例,使用ISW技术取得了理想的效果,患者对治疗结果满意。
