目的 探讨微种植体支抗对临床口腔正畸的影响。方法 根据武警吉林总队医院收治口腔正畸患者入院先后时间顺序,将50例患者分成A、B两组,A组采用口外弓支抗治疗,B组采用微型种植体支抗。观察两组术后治疗效果及不良反应等各指标变化。结果 A组17例≥80分,成功率76%;B组25例均≥80分,成功率100%。B组术后治疗成功率高于A组;经治疗后B组上中切牙倾角差和凸角差均大于A组,而磨牙移动位置则小于A组,提示B组治疗效果优于A组;术后B组口腔炎症1例,软组织轻度水肿3例,不适感1例,总体不良反应率20%,B组不良反应率低于A组。结论 微型种植体支抗口腔正畸疗效明显,术后患者不良反应率低,而且支抗稳定性高,在临床口腔正畸治疗中值得推广应用。
Abstract
Objective To study the therapeutic effect of micro-implant anchorage against orthodontics. Methods Fifty patients were divided into group A and group B according to their time of admission to the hospital. Group A was treated with extraoral anchorage while group B was treated with micro implant anchorage. The therapeutic effects and adverse reactions in both groups were observed. Results In group A,the score of 17 cases was 80 or above, and the success rate was 76%, compared with 25 cases and 100% in group B. After treatment, the incisor inclination difference and angle difference in group B were larger than in group A, but the molar movement was smaller, suggesting the better therapeutic effect in group B. In group B after surgery, there was one case of oral inflammation, three cases of soft tissue edema, and one case of discomfort, so the overall rate of adverse reactions was 20%, lower than that of group A. Conclusions The effect of mini implant anchorage for orthodontic treatment is obvious, the rate of adverse reactions is low, and the anchorage stability is high. This approach should be made more accessible for orthodontic treatment.
