摘要

背景/目的:评估锥形束(CBCT)/三维重建联合方案对自体移植磨牙临床和放射学结果的疗效:2019年8月至2022年9月注册的ISRCTN13563091对照临床试验。拉脱维亚里加斯特拉金斯大学口腔医学研究所招募了13-22岁需要拔除永久性前磨牙且至少有一颗未萌出的第三磨牙的患者。3D复制组患者(n = 30)接受了上颌CBCT扫描,并制作了第三磨牙的3D打印复制品,而对照组患者(n = 28)则没有接受扫描。临床结果包括牙齿活动度、探诊出血量和牙周袋深度,分别在 3、6 和 12 个月时进行评估。放射学结果包括牙根发育情况、磨蚀情况、根尖周状况以及 12 个月时牙冠的变化:结果:在 55 名接受干预的患者中,46 人完成了研究。对照组(22 人)和 3D-replica 组(24 人)的生存率和放射学结果无明显差异:牙根发育(p = 0.3)、牙根吸收(p = 0.057)、根尖周状况(p = 0.7)和牙冠/牙根比率变化(p = 0.4)。逻辑回归结果显示,放射学预测因素之间无明显关联(牙根吸收:p = 0.4;根尖周状态:p > 0.9;牙根发育:p = 0.8)。重要的临床结果预测因素包括总手术时间(β = 0.0043,p = 0.049)、Moorrees分期(第4期:β = -0.31,p 结论:Moorrees分期的临床结果与CBCT/3D修复的临床结果之间存在显著的相关性:CBCT/3D-replica 方案在临床和放射学结果上无显著差异。两组患者的高成功率表明,该方案主要用于优化手术效率和作为临床医生的培训工具。

Clinical Efficacy of CBCT and 3D-Printed Replicas in Molar Autotransplantation: A Controlled Clinical Trial.

Background/aim: To evaluate the efficacy of the combined cone-beam (CBCT)/3D-replicas protocol on the clinical and radiographic outcomes of autotransplanted molars.

Material and methods: Controlled clinical trial registered ISRCTN13563091 from August 2019 to September 2022. Patients aged 13-22 years requiring permanent premolar extraction and having at least one non-erupted third molar were enrolled at the Institute of Stomatology, Stradins University, Riga, Latvia. Patients in the 3D-replicas (n = 30) underwent maxillary CBCT scans and had 3D-printed replicas of the third molar fabricated, while the control group (n = 28) did not. The clinical outcomes included tooth mobility, bleeding on probing, and periodontal pocket depth assessed at 3, 6, and 12 months. The radiographic outcomes included root development, obliteration, periapical status, and crown changes at 12 months.

Results: Of the 55 patients assigned to interventions, 46 completed the study. No significant differences in survival and radiographic outcomes were found between the control (n = 22) and 3D-replica group (n = 24): root development (p = 0.3), root resorption (p = 0.057), periapical status (p = 0.7), and crown/root ratio change (p = 0.4). Logistic regression showed no significant associations between radiologic predictors (root resorption: p = 0.4; periapical status: p > 0.9; root development: p = 0.8). Significant clinical outcome predictors included total operative time (β = 0.0043, p = 0.049), Moorrees' stage (stage 4: β = -0.31, p < 0.001; stage 5: β = -0.39, p < 0.001), and four donor placement times (β = 0.93, p < 0.001), but group assignment was not a significant predictor.

Conclusions: The CBCT/3D-replica protocol showed no significant differences in the clinical or radiological outcomes. The high success rates in both groups suggest that the protocol is valuable primarily for optimizing surgical efficiency and as a training tool for clinicians.
