摘要

目的：介绍一种基于经验和研究的方法，通过虚拟支架去除（VBR）技术制造热塑性固位器（VBR固位器），并使用新的多维测量框架评估其与传统固位器相比的固位效果。方法：将38例完成固定正畸治疗的患者随机分为VBR固位器组（VBR组）和基于结石模型构建的固位器组（常规组）。通过(1)用均方根（RMS）表示的表面偏差来评估六个月以上的保留率；(2)拱型宽度/长度变化；(3)六维牙齿运动。比较各组之间的结果和临床可接受的限度（CALs: RMS为0.3 mm，牙弓变化为0.5 mm，线性/角度牙齿移动为0.5 mm/2°）。统计分析采用正态分布数据的t检验和非正态分布数据的Wilcoxon符号秩检验或Mann-Whitney U检验，统计学显著性设为α = 0.05。结果：各组间RMS值及弓形变化无显著差异，均显著低于CALs值（P < 0.05）。虽然大多数牙齿运动没有部落之间的差异,VBR组表现出显著更大的扭矩变化上犬齿(0.71±0.91°和0.40±0.77°,P < 0.05), mesiodistal / occlusogingival翻译下门齿(0.10±0.19毫米和0.06±0.09毫米/ 0.26±0.38毫米和0.12±0.25毫米,P < 0.05),降低后的牙齿和测角/ mesiodistal翻译(0.69±0.95°和0.49±0.70°/ 0.11±0.29毫米和0.09±0.16毫米,P < 0.05)。尽管有统计学差异，但所有牙齿移动均显著低于CALs （P < 0.05）。VBR入路显著缩短患者就诊时间（7.91±1.19 min vs. 64.98±4.85 min, P < 0.05）。结论：VBR固位器在六个月内表现出与传统制造固位器相当的固位效果，并显着减少了椅边时间。临床意义声明：提出的VBR固位器制造标准为临床和实验室工作流程提供了实用的建议。多维测量框架的研究结果支持VBR固位器在常规临床实践中是一种有效、高效和节省时间的正畸固位方法。

Clinical effectiveness of the prefabricated thermoplastic retainers using the virtual bracket removal technique: An in vivo study

Objectives

To introduce an experience- and research-based approach for fabricating thermoplastic retainers through the virtual bracket removal (VBR) technique (VBR retainers) and evaluate their retention effectiveness compared to conventional retainers using a novel multi-dimensional measurement framework.

Methods

Thirty-eight patients completing fixed orthodontic treatment were randomized to receive VBR retainers (the VBR group) or retainers constructed on stone models (the conventional group), respectively. Retention effectiveness over six months was evaluated via (1) surface deviations represented by root mean square (RMS); (2) arch form changes in width/length; (3) tooth movements in six dimensions. Outcomes were compared between groups and against clinical acceptable limits (CALs; 0.3 mm for RMS, 0.5 mm for arch form changes, and 0.5 mm/2° for linear/angular tooth movements). Statistical analyses included t-tests for normally distributed data and Wilcoxon signed-rank tests or Mann-Whitney U tests for non-normally distributed data, with statistical significance set at α = 0.05.

Results

No significant inter-group differences were observed in RMS values or arch form changes, with all values significantly below CALs (P < 0.05). While most tooth movements showed no inter-group differences, the VBR group exhibited statistically significantly greater torque variations in upper canines (0.71 ± 0.91° vs. 0.40 ± 0.77°, P < 0.05), mesiodistal/occlusogingival translations in lower incisors (0.10 ± 0.19 mm vs. 0.06 ± 0.09 mm/0.26 ± 0.38 mm vs. 0.12 ± 0.25 mm, P < 0.05), and angulation/mesiodistal translations in lower posterior teeth (0.69 ± 0.95° vs. 0.49 ± 0.70°/0.11 ± 0.29 mm vs. 0.09 ± 0.16 mm, P < 0.05). Despite these statistical differences, all tooth movements remained significantly lower than CALs (P < 0.05). The VBR approach significantly reduced patient visit duration (7.91 ± 1.19 min vs. 64.98 ± 4.85 min, P < 0.05).

Conclusions

VBR retainers demonstrate comparable retention effectiveness to conventionally fabricated retainers over six months and significantly reduce chairside time.

Clinical Significance

The proposed criteria for VBR retainer fabrication offer practical suggestions for clinical and laboratory workflows. The findings from a multi-dimensional measurement framework support VBR retainers as an effective, efficient, and time-saving approach for orthodontic retention in routine clinical practice.

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
