摘 要:目的分析青少年骨性Ⅲ类错[牙合]畸形患者应用上颌快速扩弓联合前方牵引治疗的临床研究。方法选取2020年6月至2022年8月收治的60例骨性Ⅲ类错[牙合]畸形患者进行研究,在治疗前后对患者上气道指标、软组织指标、硬组织指标、外貌美观性、生活质量、咀嚼效率及牙齿总咬合力进行比较。结果治疗后,患者口咽段容积(V1)、鼻咽段容积(V2)、口咽段最小截面积(S1)、鼻咽段最小截面积(S2)、口咽段最小截面积处失状径(L1)、鼻咽段最小截面积处失状径(L2)均高于治疗前,且S1显著高于治疗前(P<0.05);患者Z角、H角、上唇突角、SNA、ANB、MP-SN、U1-NA、普通人与正畸医生对患者外貌美观性评分、OHIP-14-功能限制、躯体疼痛、心理不适、(心理、生理、社交)障碍、残障评分、咀嚼效率与牙齿总咬合力均显著增加(P<0.05);而下唇倾角、U1-L1则显著降低(P<0.05)。结论青少年骨性Ⅲ类错[牙合]畸形患者应用上颌快速扩弓联合前方牵引治疗效果显著,可有效改善患者上气道指标、软组织指标、硬组织指标、增加外貌美观性、提升生活质量、提高咀嚼效率和牙齿总咬合力。Objective To analyze the clinical study of rapid palatal expansion combined with front traction for treating skeletal classⅢmalocclusion in adolescents.Methods A total of 60 adolescent outpatients with skeletal ClassⅢmalocclusion admitted t from June 2026 to August 2022 were selected.Indicators associated with the upper airway,soft tissue,hard tissue,appearance aesthetics,quality of life,chewing efficiency and total bite force of teeth were compared before and after treatment.Results After therapy,the oropharyngeal segment volume(V1),nasopharyngeal segment volume(V2),minimum cross-sectional area of oropharyngeal segment(S1),minimum cross-sectional area of nasopharyngeal segment(S2),sagittal diameter at the minimum cross-sectional area of the oropharyngeal segment(L1),Sagittal diameter at the minimum cross-sectional area of the nasopharyngeal segment(L2)were significantly higher than those before therapy(P<0.05).The Z angle,H angle,upper lip angle,SNA(the angle between the sella/nasion plane and the nasion/A plane),ANB(the angle between the NA plane and the NB plane),MP-SN(The angle between the MP and the SN plane),U1-NA(the angle between the long axis of the upper central incisor and the cranial base),aesthetic appearance score,the Use of Oral Health Impact Profile-14(OHIP-14)score,somatic pain,psychological discomfort,(mental,physical,social)disorder,handicap score,masticatory efficiency and total bite force were significantly elevated(P<0.05).The lower lip angle and U1-L1(maxillary incisor–mandibular incisor)decreased significantly(P<0.05).Conclusion The effect of rapid palatal expansion combined with front traction for treating adolescent skeletal classⅢmalocclusion is significant.It can effectively improve the indicators associated with the upper airway,soft tissue,hard tissue,appearance aesthetics,quality of life,chewing efficiency and total bite force of teeth.
