摘　　要：目的 :研究骨性反牙合患者的口周肌压力特征 ,了解口周肌压力与牙颌形态的相关性。方法 :以 2 0名成人骨性反牙合患者为研究对象 ,检测了姿势位时上下切牙区、尖牙区、磨牙区颊 (唇 )舌侧口周肌压力。结果 :与对照组相比 ,除了上下磨牙区舌侧口周肌压力外 ,骨性反牙合组中的口周肌压力大于对照组中对应区域口周肌压力 (P <0 .0 1)。骨性反牙合患者同一牙弓内左右两侧口周肌压力值无显著性差异 ,各测量区域颊侧压力均大于相应部位的舌侧压力 (P <0 .0 1) ;除了尖牙区唇侧外 ,上下对应区域口周肌压力下颌大于上颌 (P <0 .0 1) ;各牙位口周肌压力中 ,下颌唇侧的口周肌压力最大 (P <0 .0 1)。结论 :牙颌形态影响口周肌压力的大小 ,骨性反牙合患者口周肌压力的最显著的特征为姿势位时下切牙唇侧肌压力值最大。Objective:To study the characters of perioral muscle p re ssure of the adult patients with skeletal crossbite. Methods:20 patients were diagnosed to be with skeletal crossbite. The perioral muscle press ures on upper and lower central incisors, first molars and cuspids were measured buccally and lingually at rest position. 10 health adults were served as the co ntrols. Results:The perioral force in skeletal crossbite group was larger than that in the control group on the correspondence area(P<0.01 )except the lingual side of the first molars(P>0.05). In the skeletal cross bite group, the perioral force on the mandibular area was larger than that on th e correspondence maxillary area(P<0.01)except the labial side of the cuspi ds(P>0.05). The muscle pressure on the labial side was larger than that on t he lingual correspondence side in both groups(P<0.01). And the muscle pres sure on the labial side of mandibular incisors was the largest(P<0.01) in the skeletal crossbite group. Conclusion:The perioral force in t he patients with skeletal crossbite is larger than that in the health subjects, the muscle pressure on the labial side of mandibular incisors was the largest.
