To evaluate vertical stability after combined orthodontic surgical treatment of skeletal anterior open-bite malocclusion.
A literature search was performed to locate studies pertaining to vertical stability after combined orthodontic surgical treatment of skeletal anterior open-bite malocclusion. Data from the identified studies were extracted and assessed for quality. Short-term and long-term changes in the following variables were evaluated: overbite; mandibular plane, palatal plane, and intermaxillary angles; and anterior facial height.
Nine studies, all retrospective, were appropriate for inclusion after review. The postoperative follow-up period ranged from 1 to 18 years. A wide variation was present for post-treatment changes and relapse. Dentally, overbite changes showed a wide variation, with more long-term relapse observed in patients after Le Fort I osteotomy. Skeletally, the mandibular plane and intermaxillary angles showed greater long-term relapse after bimaxillary surgery than after Le Fort I osteotomy. The same trend was seen for the post-treatment increase in anterior facial height. In contrast, the palatal plane seemed to remain rather stable.
Vertical relapse is a characteristic in a certain number of patients after combined orthodontic surgical treatments regardless of surgery type. This can be observed dentally by an opening of the bite and skeletally by an increase in the mandibular plane and intermaxillary angles during long-term follow-up. Long-term skeletal relapse seems to be more common after bimaxillary surgery.
评估正畸-正颌联合治疗骨性前牙开（牙合）错（牙合）后的垂直稳定性。
进行文献检索，以查找与正畸-正颌联合治疗骨性前牙开（牙合）错（牙合）后垂直稳定性相关的研究。提取已识别研究中的数据并评估其质量。评估以下变量的短期和长期变化：覆（牙合）；下颌平面、腭平面和颌间角；以及面下1/3高度。
9项研究均为回顾性研究，经审查后适合纳入。术后随访时间为1至18年。治疗后变化和复发情况差异很大。在牙齿方面，覆（牙合）变化差异很大，勒福Ⅰ型截骨术后患者的长期复发更为明显。在骨骼方面，双颌手术比勒福Ⅰ型截骨术后下颌平面和颌间角的长期复发更明显。面下1/3高度治疗后增加也呈现相同趋势。相比之下，腭平面似乎保持相当稳定。
无论手术类型如何，正畸-正颌联合治疗后，一定数量的患者存在垂直复发的特征。在长期随访中，牙齿方面可观察到咬合打开，骨骼方面可观察到下颌平面和颌间角增加。双颌手术后长期骨骼复发似乎更常见。
