Abstract

Objective: To evaluate the effectiveness of bone anchored maxillary protraction (BAMP) in the management of class III skeletal malocclusion in children aged 11-14 years compared with an untreated control group in terms of perceived need for orthognathic surgery, skeletal and dental change, and psychological impact.

Design: A multicentre two-armed parallel randomised controlled trial.

Setting: Six UK hospital orthodontic units.

Methods: A total of 57 patients were randomly allocated into either the BAMP group (BAMPG) (n = 28) or a no treatment control group (CG) (n = 29).

Outcomes: Data collection occurred at registration (DC1),18 months (DC2) and 3 years (DC3), where skeletal and dental changes were measured from lateral cephalograms and study models. Oral Aesthetic Subjective Impact Score (OASIS) and Oral Quality of Life (OHQOL) questionnaires were used to assess the psychological impact of treatment.

Results: The mean age was 12.9 ± 0.7 years and 12.6 ± 0.9 years in the BAMPG and CG, respectively. At DC2, the BAMPG achieved a class III ANB improvement of +0.6° compared with -0.7° in the CG (P = 0.004). The overjet improvement was +1.4 mm for the BAMPG and -0.2 mm for the CG (P = 0.002). There was no evidence of any other group differences for the other skeletal or dental cephalometric outcomes (P > 0.05) or the questionnaire data (OASIS P = 0.10, OHQOL P = 0.75). At DC2, the 18-month follow-up, 22% of the BAMPG achieved a positive overjet. At the 3-year follow-up (DC3), fewer participants in the BAMPG were perceived to need orthognathic surgery (48%) compared with 75% of participants in the CG (P = 0.04), with an odds ratio of 0.31 (95% confidence interval = 0.10-0.95).

Conclusion: The BAMP technique did not show any social or psychological benefits; however, the skeletal class III improvement in ANB and the overjet change were sufficient to reduce the perceived need for orthognathic surgery by 27% compared with the CG.

与未经治疗的对照组相比，骨固定上颌前突（BAMP）治疗 11-14 岁儿童 III 类骨骼错合畸形的效果如何？多中心双臂平行随机对照试验。

目的评估骨固定上颌前突（BAMP）与未经治疗的对照组相比，在治疗11-14岁儿童III类骨骼错合畸形方面的效果，包括对正颌外科手术的认知需求、骨骼和牙齿的变化以及心理影响：设计：多中心双臂平行随机对照试验：地点：英国六家医院的正畸科：共有57名患者被随机分配到BAMP组（BAMPG）（28人）或无治疗对照组（CG）（29人）：数据收集时间为注册时（DC1）、18 个月时（DC2）和 3 年时（DC3），根据侧位头颅影像和研究模型测量骨骼和牙齿的变化。口腔美学主观影响评分（OASIS）和口腔生活质量（OHQOL）问卷用于评估治疗的心理影响：BAMPG和CG的平均年龄分别为（12.9±0.7）岁和（12.6±0.9）岁。DC2时，BAMPG的ANB改善了+0.6°，而CG的ANB改善了-0.7°（P = 0.004）。BAMPG 的上颌改善幅度为 +1.4毫米，CG 为 -0.2毫米（P = 0.002）。在其他骨骼或牙齿头形测量结果（P > 0.05）或问卷数据（OASIS P = 0.10，OHQOL P = 0.75）方面，没有证据表明存在任何其他组间差异。在 DC2，即 18 个月的随访中，22% 的 BAMPG 达到了正过切角。在3年随访（DC3）时，BAMPG中认为需要正颌手术的患者较少（48%），而CG中则有75%的患者需要正颌手术（P = 0.04），几率比为0.31（95%置信区间 = 0.10-0.95）：结论：BAMP技术没有显示出任何社会或心理方面的益处；但是，与CG相比，ANB的骨骼III级改善和过咬合的改变足以使患者对正颌手术的认知需求降低27%。

期刊介绍： The Journal of Orthodontics has an international circulation, publishing papers from throughout the world. The official journal of the British Orthodontic Society, it aims to publish high quality, evidence-based, clinically orientated or clinically relevant original research papers that will underpin evidence based orthodontic care. It particularly welcomes reports on prospective research into different treatment methods and techniques but also systematic reviews, meta-analyses and studies which will stimulate interest in new developments. Regular features include original papers on clinically relevant topics, clinical case reports, reviews of the orthodontic literature, editorials, book reviews, correspondence and other features of interest to the orthodontic community. The Journal is published in full colour throughout.
