摘　　要：目的探讨错患者矫治前后咀嚼效率的变化.方法选择恒牙列早期错患者18例,进行方丝弓矫治器治疗,采用722型光栅分光光度计的吸光度法和Manly法分别测定治疗前后的咀嚼效率.结果与矫治前比较,矫治后的吸光度值和Manly法测定值均有统计学意义(P<0.05).结论错患者矫治后咀嚼效率有改善.Objective To investigate the change of masticatory efficiency before and after the orthodontic treatment. Method 18 patients who were malocclusion of permanent dentition were treated with edgewise appliance.The masticatory efficiency before and after treatment was determined with the absorbency method using Type 722 grating spectrophotometer and with the traditional peanut chewing. Result The absorbency and the peanut were different significantly between before and after the treatment （P 〈 0.05）. Conclusion The masticatory efficiency is improved after orthodontic treatment.
