To evaluate orthodontic treatment outcome in patients treated with a lingual appliance (Incognito™ Appliance System, 3M Unitek, Monrovia, CA, USA) versus patients treated with a labial appliance (Victory series™, 3M Unitek, Monrovia, CA, USA).
A total of 72 patients were retrospectively analyzed. The complexity of each case was evaluated using the American Board of Orthodontics (ABO) Discrepancy Index (DI), and orthodontic clinical outcomes were evaluated using the ABO Objective Grading System (cast-radiograph evaluation: C‑R Eval).
The mean total ABO C‑R Eval score was 16 ± 9.1 in the labial appliance group and 12.7 ± 5.4 in lingual appliance group (p = 0.152). The mean total ABO-DI scores were 16.3 ± 7.3 and 15.4 ± 6.6 in the labial and lingual appliance groups, respectively (p = 0.445). A significant correlation was observed between the total DI and total C‑R Eval scores.
In this particular study and in the hands of two experienced orthodontists, no differences in the finishing quality of orthodontic treatments using the lingual technique or the buccal appliance technique were found. However, further prospective studies with larger sample sizes are necessary in order to generalize these results.
评价使用舌侧矫治器（Incognito™ Appliance System，3M Unitek，Monrovia，CA，USA）和唇侧矫治器（Victory 系列，3M Unitek，Monrovia，CA，USA）治疗的患者的正畸治疗效果。
回顾性分析了 72 例患者。使用美国正畸医师协会（ABO）错颌畸形指数（DI）评估每个病例的复杂性，并使用 ABO 客观评价系统（石膏-射线评价：C-R Eval）评估正畸临床疗效。
唇侧矫治器组的平均 ABO C-R Eval 总评分和舌侧矫治器组分别为 16±9.1 和 12.7±5.4（p=0.152）。唇侧矫治器组和舌侧矫治器组的平均 ABO-DI 总评分分别为 16.3±7.3 和 15.4±6.6（p=0.445）。DI 总分与 C-R Eval 总分之间存在显著相关性。
在这项特定研究中和两位经验丰富的正畸医生的手中，使用舌侧技术或唇侧矫治器技术的正畸治疗完成质量没有差异。然而，为了推广这些结果，需要进行进一步的前瞻性研究，样本量更大。
