改良型垫配合咀嚼训练矫治后牙正锁的疗效观察

摘要

目的 探讨改良型垫配合咀嚼功能训练矫正后牙正锁的临床效果.方法 选取20例下颌后牙舌倾、对颌牙颊向倾斜的后牙正锁患者,采用改良型垫进行后牙正锁间交互牵引配合术后咀嚼功能训练,观察临床疗效和测量术前术后X线头影测量分析中FH-MP、U6-PP、L6-MP的变化.结果 经过3～12个月的矫治,20例全部解除锁关系,矫治前后FH-MP、U6-PP、L6-MP均无明显差异.结论 改良型垫配合术后咀嚼功能训练能有效地矫正后牙正锁和进行锁牙垂直向的控制.%Objective To evaluate the clinical results of treating buccal crossbite of posterior teeth by modified occlusion splint combined with masticatory training. Methods 20 buccal crossbite cases with linguilly inclined lower posterior teeth and buccally inclined upper posterior teeth were treated with occlusion splint and postoperative masticatory training. Clinical results were observed and changes of FH-MP, U6-PP, L6-MP on cephalometric analysis were measured before and after treatment. Results The malocclusion of all20 cases was relieved with no change of FH-MP, U6-PP, L6-MP after treatment of 3-12 months. Conclusion Modified occlusion splint combined with masticatory training can be an effective method to treat buccal crossbite with good control of crossbite teeth vertically.
