摘　　要：目的探讨替牙期安氏Ⅲ类骨性反与患儿语音功能的相关关系。方法选择38例替牙期安氏Ⅲ类骨性反患儿为试验组,并随机选择40名替牙期正常儿童为对照组。由语音专家对试验组和对照组儿童的语音进行判听,将患儿发音错误数量与其X线头影测量片的牙、颌、面的软硬组织测量结果进行相关分析。结果替牙期骨性安氏Ⅲ错患儿大多数存在发音异常,错误发音与反覆盖及OB(J覆与覆盖之和)呈高度相关,与上下切缘间的距离呈高度正相关,与TD-PW(舌背最高点至咽后壁距离)呈正相关。结论替牙期安氏Ⅲ类骨性反患儿大部分存在语音功能障碍,发音功能障碍与切牙关系及舌位置有关。Objective To investigate the effects of skeletal Class Ⅲ malocclusion in mixed dentition on speech articulation and to look for which factors lead to the speech errors. Methods Thirty-eight children with skeletal Angle Ⅲ malocclusion in mixed dentition were selected as a sample group and 40 children with normal occlusion in mixed dentition as a control group. Two phoneticians evaluated their articulations and wrote down error phonemes respectively. The correlation analysis was undertaken between the number of errors and the measurements of patients＇ cephalometry. Results The number of errors were correlated significantly with overbite, UI-LI, OBJ （OB＋OJ） and TD-PW. Conclusion There is articulatory malfunction in the majority of skeletal Angle Ⅲ malocclusion patients in mixed dentition. Articulatory malfunction is related to the position of incisors and the tongue.
