固定矫治联合微种植体支抗在青少年安氏Ⅱ类错(牙合)畸形治疗中的应用

Application of Fixed Orthodontics Combined with Micro-implant Anchorage in the Treatment of Class Ⅱ Malocclusion in Adolescents

目的:探讨固定矫治联合微种植体支抗治疗青少年安氏Ⅱ类错(牙合)畸形患者的疗效。方法:将2019年1月-2021年12月笔者医院收治的85例安氏Ⅱ类错(牙合)畸形患者纳入研究。根据是否配合使用微种植体支抗分为对照组(n=42)和观察组(n=43)。对照组患者采用固定矫治器治疗,观察组患者采用固定矫治联合微种植体支抗治疗。随访1年,比较两组SNA角、SNB角、GO-GN-SN角、OP-SN角等颌面部指标,比较两组前牙覆(牙合)覆盖、磨牙咬合关系、中线关系等错(牙合)畸形指标。治疗后,两组生活质量采用SF-36生活质量量表评估比较,采用医院自制外观功能满意度对两组矫治满意度进行评估比较。结果:治疗后,两组SNA值略有下降,SNB值、GO-GN-SN值、OP-SN值略有增加,且观察组SNA值低于对照组,SNB值、GO-GN-SN值、OP-SN值均高于对照组(P<0.05);治疗后,两组前牙覆盖、前牙覆(牙合)、磨牙咬合关系、中线关系评分均低于治疗前,且观察组低于对照组(P<0.05);治疗后,观察组心理功能、运动功能、饮食功能及生理功能等生活质量评分均高于对照组(P<0.05);治疗后,观察组外形、舒适度、咬合功能和便捷性等满意度评分均高于对照组(P<0.05)。结论:青少年安氏Ⅱ类错(牙合)畸形患者应用固定矫治器联合微种植体支抗治疗效果显著,可有效改善患者颌面部组织形态,降低错(牙合)畸形严重程度,提高患者生活质量,患者满意度更高。

Objective To investigate the effect of fixed orthodontics combined with micro-implant anchorage in the treatment of Class Ⅱ malocclusion in adolescents. Methods Eighty-five patients with Class Ⅱ malocclusion treated in the author's hospital from January 2019 to December 2021 were included in the study. They were divided into control group(n=42) and observation group(n=43) according to whether the anchorage nail was used together for planting. The patients in the control group were treated with fixed orthodontic treatment, and the patients in the observation group were treated with fixed orthodontic treatment combined with anchorage nail implantation. The SNA Angle, SNB Angle, GO-GN-SN Angle and OP-SN Angle were compared between the two groups after one year of follow-up. Anterior overjet, overbite, molar occlusion and midline relationship were compared between the two groups. The quality of life of the two groups after treatment was evaluated by SF-36 quality of life scale, and the satisfaction of orthodontic treatment was evaluated by the satisfaction of appearance and function made by hospital. Results After treatment, the value of SNA decreased slightly, and the values of SNB, GO-GN-SN and OP-SN increased slightly in both groups. The value of SNA in the observation group was lower than that in the control group, while the values of SNB, GO-GN-SN and OP-SN in the observation group were higher than those in the control group(P<0.05).After treatment, the scores of anterior overjet, anterior overbite, molar occlusal relationship and midline relationship in both groups were lower than those before treatment, and those in the observation group were lower than those in the control group(P<0.05). After treatment, the scores of psychological function, motor function, diet function and physiological function in the observation group were higher than those in the control group(P<0.05). After treatment, the satisfaction scores of appearance,comfort, occlusal function and convenience in the observation group were higher than those in the control group(P<0.05).Conclusion The application of fixed appliance combined with micro-implant anchorage in adolescent patients with Angle Class Ⅱ malocclusion has a significant effect, which can effectively improve the maxillofacial tissue morphology, reduce the severity of malocclusion, improve the quality of life of patients, and improve patient satisfaction.
