INFLUENCES ON STABILITY FOLLOWING ORTHOGNATHIC SURGERY

尽管牙颌面畸形的治疗取得了成功，但使用 正畸和手术，有些类型的畸形仍然不能 纠正了可预测的结果、长期稳定性和患者 满足感。这项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 阐明牙面畸形治疗的最终结果， 利用和扩大北卡罗来纳大学广泛的数据库。 关于长期骨骼和牙齿变化和患者的数据 对这些变化的评估将出于三个目的：(1) 更清楚地区分患者感知的结果和客观结果 正颌外科与单纯正畸治疗牙周炎的比较 牙面畸形；(2)将短期和长期风险置于 这两种类型的治疗都是前瞻性的，这样患者可以做出更多 在可供选择的方法之间做出知情选择；以及(3)澄清 正颌外科中允许门诊(日间手术)的情况 护理，而不是住院治疗，通过评估 客观和患者感知的体验和发生的不良事件 在这些设置中的每一个中。

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.
