The aim of this study was to examine the treatment outcomes, particularly the orthodontic decompensation before surgery, in patients who underwent orthognathic treatment and were treated with completely customised lingual appliances (CCLAs).
25 patients who received combined orthognathic treatment for skeletal Class II (N = 10) or Class III (N = 15) malocclusion were retrospectively investigated. Study models from before treatment (T0), immediately before surgery (T1) and after treatment (T2), as well as digitised setup and operation models, were analysed using PAR Index and by measuring tooth pairs in contact.
The initial PAR scores were comparable (T0: Class II: 33.30 ± 7.85; Class III: 35.90 ± 1.20; p = 0.539), and significant improvements were observed following treatment (T0 vs. T2: Class II: p = 0.002; Class III: p = 0.002). Excellent final PAR scores were recorded, with no statistical differences between the groups (T2: Class II: 1.60 ± 2.80; Class III: 0.80 ± 2.08; p = 0.246). The PAR scores for setup and operation models were 0.00 ± 0.00 and 4.20 ± 3.29 for Class II and 0.07 ± 0.26 and 2.47 ± 1.92 for Class III, respectively. No significant differences were found between setup and final model (Class II: p = 0.063; Class III: p = 0.125), but between OP and final model (Class II: p = 0.002; Class III: p = 0.001). Tooth pairs in contact demonstrated similar results.
Using CCLAs in combined orthognathic treatment is efficient and leads to high-quality outcomes in Class II and III patients. Moreover, it enables excellent dental arch alignment before surgery.
Optimal pre-surgical dental arch alignment, both before orthognathic surgery and after the completed therapy, can be achieved using CCLAs.
本研究旨在探讨接受正颌治疗并使用完全定制舌侧矫治器（CCLA）治疗的患者的治疗效果，尤其是术前的正畸去代偿情况。
回顾性调查25例接受骨骼II类（N = 10）或III类（N = 15）错牙合联合正颌治疗的患者。使用PAR指数并通过测量接触的牙对，分析治疗前（T0）、手术前即刻（T1）和治疗后（T2）的研究模型，以及数字化排牙和手术模型。
初始PAR评分具有可比性（T0：II类：33.30±7.85；III类：35.90±1.20；p = 0.539），治疗后观察到显著改善（T0与T2比较：II类：p = 0.002；III类：p = 0.002）。记录到优异的最终PAR评分，两组之间无统计学差异（T2：II类：1.60±2.80；III类：0.80±2.08；p = 0.246）。II类和III类的排牙和手术模型的PAR评分分别为0.00±0.00和4.20±3.29，以及0.07±0.26和2.47±1.92。排牙模型与最终模型之间未发现显著差异（II类：p = 0.063；III类：p = 0.125），但手术模型与最终模型之间存在显著差异（II类：p = 0.002；III类：p = 0.001）。接触的牙对显示出类似结果。
在联合正颌治疗中使用CCLA是有效的，并且在II类和III类患者中能产生高质量的治疗效果。此外，它能在手术前实现优异的牙弓排齐。
使用CCLA可在正颌手术前和完成治疗后实现最佳的术前牙弓排齐。
