Abstract

Background/Aim

This study aimed to develop a protocol that combines cone-beam computed tomography (CBCT), software, and 3D printing to design 3D replicas for tooth autotransplantation. The goal was to evaluate the impact of this approach on the extraoral time of the donor teeth and the total surgical time, thereby enhancing surgical efficiency and outcomes.

Materials and Methods

A non-randomized trial (protocol 10.1186/ISRCTN13563091) was conducted at Riga Stradins University, enrolling 46 patients (13–22 years old) who required molar extraction and possessed a non-erupted third molar. The patients were sequentially assigned to a 3D replica group (24 patients) or a control group (22 patients). The primary outcome measured was the extra-alveolar time of the donor tooth, and the secondary outcome was the total duration of surgery. Both were assessed using a sample size capable of detecting a 10-min difference. A generalized linear model adjusted for various factors was used to test for significant time differences (p < .05) between the groups.

Results

Forty-six patients were included in this analysis. The effect of using 3D replicas was not statistically significant and was associated with a decrease in the extraoral time of the donor tooth in seconds (β = −9.35, 95% CI [−40.86, 22.16]). For the total surgical time in minutes, the use of 3D replicas had a statistically significant impact, reducing the operation duration in minutes (β = −13.42, 95% CI [−24.50, −2.34]). No early complications were observed in either group, with all teeth present at 3–4 weeks post-surgery.

Conclusions

The integration of 3D printing technology can enhance the efficiency of autotransplantation surgeries, primarily by reducing surgical time.

3D打印复制品对第三磨牙自体移植手术持续时间的影响：一项对照临床试验。

背景/目的：本研究旨在开发一种结合锥形束计算机断层扫描（CBCT）、软件和3D打印的协议，以设计用于牙齿自体移植的3D复制品。目的是评估这种方法对供牙口外时间和总手术时间的影响，从而提高手术效率和结果。材料和方法：在里加斯特拉丁大学进行了一项非随机试验（方案10.1186/ISRCTN13563091），共招募了46名患者（13-22名岁），需要拔除臼齿并拥有未萌出的第三颗臼齿。患者被依次分配到3D复制品组（24名患者）或对照组（22名患者）。测量的主要结果是供牙的牙槽外时间，次要结果是手术的总持续时间。使用能够检测10分钟差异的样本量对两者进行评估。使用根据各种因素调整的广义线性模型来检验显著的时间差异（p 结果：46名患者被纳入本分析。使用3D复制品的效果没有统计学意义，并且与供牙口腔外时间（以秒为单位）的减少有关（β = -9.35，95%置信区间【-40.86，22.16】）。对于以分钟为单位的总手术时间，3D复制品的使用具有统计学意义，缩短了以分钟为单元的手术持续时间（β = -13.42，95%置信区间[24.50，-2.34]）。两组均未观察到早期并发症，所有牙齿均在3-4岁时出现结论：3D打印技术的集成可以提高自体移植手术的效率，主要是通过减少手术时间。
