摘　　要：目的:研究微种植体支抗对错(牙合)畸形患者牙周炎性微环境及牙齿美观度的影响。方法:选取2019年2月-2021年2月笔者医院收治的118例错(牙合)畸形患者,采用系统随机法分为观察组(n=59,自锁托槽矫治器+微种植体支抗正畸治疗)和对照组(n=59,自锁托槽矫治器+Nance弓联合横腭杆支抗正畸治疗)。观察矫正前、矫正6个月后患者的咬合力、咀嚼效率、牙齿美观指数、牙周细胞实验室指标[包括白细胞介素6(Interleukin-6,IL-6),白细胞介素1β(Interleukin-1β,IL-1β)、肿瘤坏死因子(Tumornecrosisfactor,TNF-α)、金属基质蛋白酶9(Matrix metalloproteinase-9,MMP-9)],观察矫正前、矫正后两组患者的牙齿体积(侧切牙、中切牙、尖牙)差变化,统计两组并发症(牙齿松动、牙龈炎、组织水肿)发生情况。结果:矫正6个月后,两组患者咬合力、咀嚼效率、牙齿美观指数较矫正前降低,观察组咬合力、咀嚼效率高于对照组(P<0.05),牙齿美观指数低于对照组(P<0.05);两组牙周细胞IL-6、IL-1β、TNF-α、MMP-9较矫正前升高,但观察组低于对照组(P<0.05)。矫正后,两组患者上下颌侧切牙、中切牙、尖牙体积较矫正前下降(P<0.05),但组间比较差异无统计学意义(P>0.05)。观察组患者并发症发生率低于对照组(P<0.05)。结论:自锁托槽矫治器联合微种植体支抗治疗可提高错(牙合)畸形患者的咬合力、咀嚼效率,能改善患者牙周炎性微环境,减少并发症,达到口腔美观效果。Objective To study the influence of micro-implant anchorage on periodontal inflammatory microenvironment and aesthetics in patients with malocclusion.Methods 118 patients with malocclusion who were treated in the hospitalwere selected between February 2019 and February 2021,and they were divided into the observation group(n=59,orthodontic treatment with self-locking bracket appliance+micro-implant anchorage)and the control group(n=59,orthodontic treatment with self-locking bracket appliance+Nance arch-transpalatal arch anchorage)by the systematic randomization.Occlusal force,chewing efficiency,tooth beauty index,periodontal cell laboratory indicators[interleukin-6(IL-6),interleukin-1β(IL-1β),tumor necrosis factor(TNF-α),matrix metalloproteinase 9(MMP-9)]were observedbefore correction and after 6 months of correction.Tooth volume(lateral incisor,central incisor,canine)were observedbefore correction and after of correction.The occurrence of complications(tooth loosening,gingivitis,tissue edema)were statistically analyzed in the two groups.Results After 6 months of correction,the occlusal force,chewing efficiency and tooth beauty index of the two groups of patients were lower than those before correction,and the occlusal force and chewing efficiency in the observation group were higher than those in the control group(P<0.05),the tooth beauty index in the observation group were lower than those in the control group(P<0.05).The levels of IL-6,IL-1β,TNF-αand MMP-9 in periodontal cells in the two groups were enhanced compared with those before correction,but the levels in the observation group were lower than those in the control group(P<0.05).After of correction,the volumes of maxillary and mandibular lateral incisors,central incisors andcanines in both groups werereduced compared to before correction(P<0.05),but there were no statistical differences between the two groups(P>0.05).The incidence rates of complications were lower in the observation group compared with those in the control group(P<0.05).Conclusion
