目的:探讨微型种植体支抗在口腔正畸治疗中的效果。方法:将80例需口腔正畸治疗的患者随机分为两组,对照组给予传统正畸治疗,观察组给予微型种植体支抗治疗,观察和比较两组的手术成功率、治疗结果及随访2周期间不良反应的发生情况。结果:观察组手术成功率(92.5%)显著高于对照组(70.0%,P<0.05)。治疗后,观察组上中切牙凸距差为(4.54±1.21)mm(增加80.9%)、上中切牙倾角为(27.27±4.45)mm(增加132.3%)、下齿槽座角为(1.49±0.53)mm(增加81.7%)、尖牙间宽度为(1.73±0.69)mm(增加143.7%)、磨牙移位为(3.25±0.73)mm(降低37.1%)、上齿槽座角为(-1.81±0.46)mm(降低147.9%),与对照组相比,均有显著性差异(P<0.05)。随访2周内,与对照组相比,观察组口腔炎症、口腔感染、不适感降低以及软组织轻度浮肿等不良反应的发生率(10%)显著低于对照组(30%,P<0.05)。结论:微型种植体支抗在口腔正畸治疗中能发挥理想的矫治效果,稳定性好,手术成功率和安全性均较高。
Objective: To investigate the effect of mini-implant anchorage in orthodontic treatment. Methods: Eighty patients who needed oral orthodontic treatment were randomly divided into two groups. The control group was given traditional orthodontic treatment. The observation group was given micro-implant supportive therapy. The success rate, the treatment outcome and the follow-up of the two groups were observed and compared Adverse reactions during 2 weeks. Results: The success rate of operation in the observation group (92.5%) was significantly higher than that in the control group (70.0%, P <0.05). After treatment, the difference of the maxillary incisors in the observation group was (4.54 ± 1.21) mm (80.9% increase), the inclination of the upper incisors was (27.27 ± 4.45) mm (132.3%), the lower incisors (1.73 ± 0.69) mm (143.7% increase), molars shift (3.25 ± 0.73) mm (decrease 37.1%), and the angle of the upper alveolar was (-1.81 ± 0.46) mm (decreased by 147.9%) compared with the control group, there was significant difference (P <0.05). In the 2-week follow-up, the incidence of oral adverse reactions, oral infections, discomfort and mild soft tissue edema in the observation group was significantly lower than that in the control group (10%, 30%, P <0.05) . Conclusion: Micro-implant anchors can exert the ideal correction effect in oral orthodontic treatment. The stability is good, and the success rate and safety of operation are high.
