摘　　要：目的研究板治疗对骨性Ⅰ类错畸形患者双侧髁突功能位置和诊断的影响。方法 板治疗34例骨性Ⅰ类错畸形患者。使用髁突位置测量仪(measures of condyle displacement,MCD)测量患者治疗前、中、后的正中关系(centric relation,CR)位与正中(centric occlusion,CO)位的差异,板治疗结束时重新评估错畸形诊断,比较板治疗前后功能位置差异和左右双侧对称性的改变。使用配对检验对数据统计分析。结果 板治疗后患者CR与CO位的双侧髁突功能位置变化的对称性比治疗前有改善。板治疗后,患者中有2人(7.1%)骨性诊断改变,有6人(21.4%)的安氏诊断改变。结论 板治疗可以使骨性Ⅰ类错畸形患者髁突CO-CR位置差异趋于协调,对称性得到改善。必要的板治疗可以改善错畸形患者诊断的正确率。Objective To investigate the effect of splint treatment of the skeletal Class Ⅰ malocclusion patients on condylar functional position and symmetry changes and diagnosis. Methods Thirty-four patients with skeletal Class Ⅰ malocclusion were treated by occlusion splint. The MCD （ measures of the condyle displacement） was used to compare condylar position between centric relation （CR） and centric occlusion （CO）. The frequency, direction and magnitude of CO-CR difference were determined, and the changes of the symmetry of the bilateral condylar before and after the treatment evaluated. The patients were re-diagnosed after the treatment. Results After the splint treatment, the symmetry of the bilateral condylar was improved and 14. 7% （5/34-） of the patients had different skeletal classification. 17.6% （6/34） of the patients had different Angle＇s classification. Conclusion The splint treatment improved the symmetry of the bilateral condylar in skeletal Class Ⅰ malocclusion patients and the accuracy of the diagnosis.
