Abstract

Purpose

The BioBiteCorrector® (BBC) appliance was introduced as a further development of the Herbst appliance; however, there is no research comparing their treatment outcomes.

Materials and methods

Caucasian healthy patients with at least 5 mm overjet were included and treated with either Herbst or BBC, both combined with fixed appliances, by one experienced orthodontist at a private practice in Switzerland. Treatment effectiveness was evaluated in terms of occlusal outcomes via the Peer Assessment Rating (PAR) and Index of Orthodontic Treatment Need (IOTN) indices, for which groups were matched at baseline. Data collection took place before bonding and after debonding and data was statistically analyzed with linear/logistic regressions at 5%.

Results

Each group was comprised of 58 patients. Patient and treatment related characteristics did not demonstrate any clinically relevant differences at baseline. The overall treatment duration was 19.3 ± 5.3 and 22.9 ± 5.7 months for the Herbst and BBC respectively (P < 0.001). The main outcomes of absolute PAR reduction, % PAR reduction, PAR improvement, or great PAR improvement were not statistically significant between groups (P > 0.05 in all instances); however, patients treated with Herbst had slightly worse overall IOTN scores (P < 0.03). The findings did not significantly change after controlling for confounders.

Conclusion

Both Herbst and BBC appeared to be equally effective in improving class II malocclusion, yet the BBC appliance led to slightly longer overall treatment duration.

BioBiteCorrector®和Herbst矫治器联合固定矫治器在II类患者中的比较评估：PAR和IOTN指数的回顾性队列研究

BioBiteCorrector®（BBC）器械作为Herbst器械的进一步发展而推出；然而，没有研究比较他们的治疗结果。材料与方法：研究对象为覆盖面积大于5mm的高加索健康患者，由瑞士一家私人诊所的一位经验丰富的正畸医生使用Herbst或BBC联合固定矫治器进行治疗。通过同伴评估评分（PAR）和正畸治疗需求指数（IOTN）指数来评估咬合结果的治疗效果，两组在基线上匹配。数据收集在粘接前和脱粘后进行，数据以5%的线性/逻辑回归进行统计分析。结果每组58例患者。患者和治疗相关特征在基线时未显示任何临床相关差异。Herbst和BBC的总治疗时间分别为19.3±5.3和22.9±5.7个月(P <；0.001)。两组间PAR绝对降低、PAR降低%、PAR改善或PAR显著改善的主要指标差异均无统计学意义(P >；0.05)；然而，接受Herbst治疗的患者总体IOTN评分略差(P <；0.03)。在控制混杂因素后，研究结果没有显著变化。结论Herbst矫治器与BBC矫治器对ⅱ类错牙合的改善效果相同，但BBC矫治器的总治疗时间略长。
