INFLUENCES ON STABILITY FOLLOWING ORTHOGNATHIC SURGERY

尽管使用牙颌面畸形治疗取得了成功 正畸和手术，某些类型的畸形仍然无法修复 通过可预测的结果、长期稳定性和患者的纠正 满意。 该提案的目标是描述风险 与治疗后长期不稳定相关的因素，以及 阐明牙颌面畸形治疗的最终结果， 使用和扩大北卡罗来纳大学的广泛数据库。 有关长期骨骼和牙齿变化以及患者的数据 对这些变化的评估将出于三个目的进行审查：(1) 更清楚地区分患者感知的结果和客观结果 正颌手术与单纯正畸治疗在治疗中的比较 牙颌面畸形； (2) 兼顾短期和长期风险 正确看待这两种类型的治疗，以便患者能够获得更多 替代方法之间的明智选择； (3) 澄清 允许门诊（日间手术）进行正颌手术的情况 护理而不是住院治疗，通过评估 客观和患者感知的经历和发生的不良事件 在每个设置中。

Despite the success of treating dentofacial deformities using orthodontics and surgery, some types of deformities still cannot be corrected with predictable results, long-term stability, and patient satisfaction. The goals of this proposal are to delineate the risk factors associated with long term instability after treatment, and to clarify the ultimate outcomes of the treatment of dentofacial deformity, using and enlarging the extensive University of North Carolina database. Data on the long-term skeletal and dental changes and the patients evaluation of these changes will be examined for three purposes: (1) to more clearly differentiate the patient-perceived and objective outcomes of orthognathic surgery vs. Orthodontics alone in the treatment of dentofacial deformity; (2) to place both short- and long-term risks of both types of treatment in perspective so that patients can make more informed choices between alternative approaches; and (3) to clarify the circumstances in orthognathic surgery that allow outpatient (day-op) care as opposed to inpatient hospitalization by evaluating both the objective and patient perceived experience and adverse events that occur in each of these settings.
