正颌联合正畸治疗骨性双颌前突畸形的临床疗效观察

摘要

Objective:To evaluate the effect of combined surgical and orthodontic treatment in osteal bimaxillary protrusion.Method:Twenty-two patients with osteal bimaxillary protrusion were corrected by combined surgical and orthodontic treatment.Result: None of the twenty-two patients had complications such as tooth discoloration or odontonecrosis after the treatment.According to the X-rays analysis and clinical manifestation, the coordination of tooth,jaw bone and lineament was proved successful.After clinical and follow up observation,the occlusion was well and the effect was stable.Conclusion: Combined surgical and orthodontic treatment can not only guarantee soft tissues like muscles be conditioned to the new position of jaw bone, but also help construct the stable occlusion in patients with osteal bimaxillary protrusion.%目的:观察正颌联合正畸治疗骨性双颌前突畸形的临床疗效.方法:22例骨性双颌前突患者,采用正颌联合正畸的治疗方法进行矫形治疗.结果:22例患者术后均无牙齿变色坏死等并发症发生,且根据X线测量分析及临床所见,牙、颌、面关系协调取得较好的效果,咬合天系良好,经过临床观察和随访,效果稳定.结论:正颌联合正畸治疗可以有效地保证骨性双颌前突患者肌肉等软组织对新的颌骨位置的适应和改变,并且有利于咬合关系的稳定.
