〕目的 :了解单侧完全性唇腭裂 (UCL P)患者的牙合力水平 ,借以掌握其口腔功能状况。方法 :以 MBF- 1型牙合力计测试 2 2名 UCL P患者上颌后牙牙合力和 2 5名正常牙合者的相应牙合力 ,同时测定其咀嚼效能和检查其上颌后牙的咬合接触状况。结果 :1UCL P患者上颌后牙牙合力明显低于正常牙合者 (P<0 .0 5 ) ;2 UCL P患者上颌后牙牙合力无性别差异。结论 :牙合力水平低下和咬合接触不良是 UCL P患者咀嚼效能低下的重要原因
Objective: To understand the level of occlusal force in patients with unilateral complete cleft lip and palate (UCL P) so as to understand the oral functional status. Methods: The corresponding occlusal force of the maxillary posterior teeth and the normal occlusion of 25 maxillary posterior teeth of 2 UCL P patients were measured by MBF-1 type dental force meter. The masticatory efficacy and the occlusal contact status of the maxillary posterior teeth were measured. Results: The occlusal force of maxillary posterior teeth in 1UCL P group was significantly lower than that in normal occlusion group (P <0.05). There was no gender difference in the occlusal force of maxillary posterior teeth in 2 UCL P patients. Conclusion: The low level of occlusal force and maladjusted occlusion are the main reasons for the low masticatory efficiency in UCL P patients
