单侧上颌骨缺失修复后咀嚼效率的测定

The Analysis of Masticatory Efficiency after Maxillofacial Prosthetic Treatment for Unilateral Maxillary Defect

目的探讨单侧上颌骨缺失赝复体修复的咀嚼效率。方法采用吸光度法,分别测定单侧上颌骨缺失赝复体修复前后的咀嚼效能。结果初戴赝复体1周、1个月、3个月后,与初戴前后比较有显著性差异(F=0.635,P=0.002),初戴1个月后咀嚼效率提高了59.98%。结论对单侧上颌骨缺失,赝复体修复能显著提高患者的咀嚼效率,并在1个月后达到稳定。

Objective To evaluate the clinic results of maxillofacial prosthetic treatment for unilateral maxillary defect.Methods Masticatory efficiency was tested before and after maxillofacial prosthetic treatment for unilateral maxillary defect.Results There was significant difference between one week,one month,three months after treatment and before treatment(F=0.635,P=0.002).Masticatory efficiency was increased by59.98%after one month.Conclusion Maxillofacial prosthetic treatment can significantly increase the masticatory efficiency of unilateral maxillary defect.It remains stable one month later.
