For patients whose orthodontic problems are so severe that neither growth modification nor camouflage offers a solution, surgery to realign the jaws or reposition dentoalveolar segments is the only possible treatment option left. One indication for surgery obviously is a malocclusion too severe for orthodontics alone. It is possible now to be at least semiquantitative about the limits of orthodontic treatment, in the context of producing normal occlusion as the diagrams of the "envelope of discrepancy" indicate. In this case report we present orthognathic treatment plan of an adult female patient with skeletal class III malocclusion. Patient's malocclusion was decompensated by orthodontic treatment just before the surgery and then normal jaw relationship achieved by bilateral sagittal split osteotomy.
对于正畸问题极为严重,生长改良或掩饰性治疗均无法解决的患者,通过手术重新排列颌骨或重新定位牙-牙槽骨段是唯一可行的治疗选择。显然,手术的一个指征是错牙合畸形严重到仅靠正畸治疗无法解决。如今,在以产生正常牙合为背景的情况下,如“差异包络线”图所示,至少可以对正畸治疗的限度进行半定量分析。在本病例报告中,我们展示了一名成年女性骨性III类错牙合畸形患者的正颌治疗方案。患者的错牙合畸形在手术前通过正畸治疗得到代偿,然后通过双侧矢状劈开截骨术实现了正常的颌骨关系。
