INFLUENCES ON STABILITY FOLLOWING ORTHOGNATHIC SURGERY

尽管成功地治疗牙面畸形， 整形外科和手术，有些类型的畸形仍然不能 通过可预测的结果、长期稳定性和患者进行纠正 满意 本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局， 使用和扩大北卡罗来纳州的广泛的大学数据库。 关于长期骨骼和牙齿变化以及患者的数据 对这些变化的评价将出于三个目的进行审查：（1） 更清楚地区分患者感知和客观结果 正颌外科手术与单纯正畸治疗 牙面畸形;（2）将短期和长期风险 这两种类型的治疗的角度，使病人可以使更多的 在各种备选办法之间作出知情的选择;（3）澄清 允许门诊患者（日间手术）的正颌外科情况 护理，而不是住院治疗，通过评估这两个 客观和患者感知体验以及发生的不良事件 in each每of these settings设置.

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.
