摘要: 目的:评价上颌快速扩弓与上颌交替快速扩缩配合前方牵引治疗骨性Ⅲ类错𬌗畸形的效果。方法:选择青岛市胶州中心医院2021年5月—2024年4月收治的82例骨性Ⅲ类错𬌗畸形患者,按就诊时间分为两组,对照组(n=40)采用上颌快速扩弓配合前方牵引,试验组(n=42)采用上颌交替式快速扩缩配合前方牵引,比较两组矫治效果。结果:治疗后3个月,试验组Z角、H角和上唇突角显著高于对照组,下唇倾角显著低于对照组(P<0.05);试验组SNA、U1-NA、ANB、最大咬合接触面积和最大咬合力显著高于对照组,U1-L1、SNB显著低于对照组(P<0.05);试验组咀嚼效率、口腔健康影响程度量表(OHIP-14)评分显著高于对照组(P<0.05)。结论:上颌交替式快速扩缩配合前方牵引能提高骨性Ⅲ类错𬌗畸形患者咬合功能和咀嚼效率,改善患者软、硬组织指标。

Abstract: PURPOSE: To evaluate the efficacy of rapid maxillary expansion and maxillary alternate rapid expansion combined with maxillary protraction in the treatment of Class III bony malformations. METHODS: A total of 82 patients with skeletal Class III malocclusion admitted to Jiaozhou Central Hospital of Qingdao from May 2021 to April 2024 were selected and divided into two groups according to admission time. The control group (n=40) was treated with simple maxillary rapid arch expansion combined with maxillary protraction. The experimental group (n=42) was treated with maxillary alternate rapid expansion and contraction combined with maxillary protraction, the therapeutic effect of the two groups was compared. RESULTS: Three months after treatment, the Z-angle, H-angle and upper lip angle of the experimental group were significantly higher than those of the control group, and the lower lip inclination was significantly lower than that of the control group(P<0.05). SNA, U1-NA, ANB indexes, maximum occlusal contact area and maximum biting force in the experimental group were significantly higher than those in the control group, while U1-L1 and SNB indexes were significantly lower than those in control group (P<0.05). The masticatory efficiency and oral health impact scale (OHIP-14) scores of the experimental group were significantly higher than those of the control group(P<0.05). CONCLUSIONS: Rapid maxillary expansion combined with maxillary protraction can improve the occlusal function and masticatory efficiency of patients with skeletal Class III malocclusion, and improve the soft and hard tissue indexes of the patients.
