Abstract

Background: The aim of the present study was to compare the vertical dimension changes, before and after treatment, in two groups of growing patients, one group treated with clear aligner therapy versus a group treated with Quad-helix and bite-block therapy.

Methods: The studied sample was composed of n. 40 patients (20 females and 20 males with a mean age of 8.6 ± 1.8 years), enrolled from the Department of Orthodontics at Policlinico of Rome Tor Vergata. The original sample was randomly divided into two groups: Group IF (Invisalign First) and Group BB (Quad-helix and bite block). Pre- (T0) and post-treatment (T1 after 12 months) lateral cephalograms were collected from all the selected patients. Nine cephalometric parameters, both angular and linear, were measured and recorded for each cephalogram.

Results: No statistically significant changes were found between both the IF and BB groups at T0, while statistically significant changes were observed in both groups (BB and IF) between T0 and T1 (after 12 months of active therapy), p < 0.005.

Conclusions: Both therapies were able to control the patient's vertical condition. To date, the use of conventional appliances seems to have slightly better efficacy in controlling the vertical dimension than aligner therapy.

两种不同治疗方案的垂直尺寸控制：隐适美第一阶段和咬合阻滞--回顾性研究

背景：本研究的目的是比较两组生长期患者治疗前后垂直尺寸的变化，一组采用透明矫治器治疗，另一组采用四螺旋和咬合阻断治疗：研究样本由罗马托尔韦尔加塔医院正畸科的 40 名患者（20 名女性和 20 名男性，平均年龄为 8.6 ± 1.8 岁）组成。原始样本被随机分为两组：IF组（Invisalign First）和BB组（Quad-helix and bite block）。收集了所有入选患者治疗前（T0）和治疗后（12 个月后的 T1）的侧头影。测量并记录了每张头颅照片的九个头颅测量参数，包括角度和线性参数：结果：IF组和BB组在T0时均未发现有统计学意义的变化，而在T0和T1（积极治疗12个月后）之间，两组（BB组和IF组）均观察到有统计学意义的变化，P < 0.005：两种疗法都能控制患者的垂直状况。迄今为止，使用传统矫治器在控制垂直度方面的疗效似乎略优于矫治器疗法。

期刊介绍： Children is an international, open access journal dedicated to a streamlined, yet scientifically rigorous, dissemination of peer-reviewed science related to childhood health and disease in developed and developing countries. The publication focuses on sharing clinical, epidemiological and translational science relevant to children’s health. Moreover, the primary goals of the publication are to highlight under‑represented pediatric disciplines, to emphasize interdisciplinary research and to disseminate advances in knowledge in global child health. In addition to original research, the journal publishes expert editorials and commentaries, clinical case reports, and insightful communications reflecting the latest developments in pediatric medicine. By publishing meritorious articles as soon as the editorial review process is completed, rather than at predefined intervals, Children also permits rapid open access sharing of new information, allowing us to reach the broadest audience in the most expedient fashion.
