目的:应用配对统计学测量方法通过对比单纯正颌治疗和正畸-正颌联合治疗上颌前突畸形的疗效,明确正颌治疗和正畸治疗的疗效及相互关系。方法:36例恒牙期骨性上颌前突病例,根据上颌前突程度两两配对,分配于A,B两组;A组上颌前突患者只接受正颌治疗,B组患者接受正畸-正颌联合治疗。结果:两组患者的上颌前突畸形均较术前有很大的改善(P<0.05),B组术后能获得较好的疗效及较好的稳定性(P<0.05)。结论:应用正颌和正畸-正颌联合治疗上颌前突均能取得良好的面型改善,正颌术前术后正畸治疗可以对疗效及术后稳定性有良性的促进作用。
Objective: To compare the curative effects of simple orthognathic surgery and orthodontic-orthognathic joint in the treatment of maxillary protrusion deformity by using the statistical method of paired statistics, so as to clarify the curative effect and the correlation between orthognathic and orthodontic treatment. Methods: Thirty-six cases of permanent maxillary protrusion were divided into two groups according to the extent of maxillary protrusion and were assigned to group A and group B. Patients in group A received orthognathic treatment only in patients with maxillary protrusion and in group B received orthodontic- Orthognathic combined treatment. Results: The maxillary protrusion deformity in both groups was significantly improved compared with that before operation (P <0.05). The postoperative B group had better curative effect and better stability (P <0.05). Conclusion: Orthognathic and orthognathic - orthognathic surgery combined with orthognathic surgery can achieve good improvement of facial features. Orthodontics and orthognathic surgery can improve the curative effect and postoperative stability.
