Abstract

OBJECTIVE

To evaluate the construction reproducibility of a composite tooth model (CTM) composed of an intraoral-scanned crown and a cone-beam computed tomography (CBCT)-scanned root.

METHODS

The study assessed 240 teeth (30 central incisors, 30 canines, 30 second premolars, and 30 first molars in the maxillary and mandibular arches) from 15 young adult patients whose pre-treatment intraoral scan and CBCT were available. Examiner-Reference (3 years' experience in CTM construction) and Examiners-A and Examiner-B (no experience) constructed the individual CTMs independently by performing the following steps: image acquisition and processing into a three-dimensional model, integration of intraoral-scanned crowns and CBCT-scanned teeth, and replacement of the CBCT-scanned crown with the intraoral-scanned crown. The tooth axis angle in terms of mesiodistal angulation and buccolingual inclination of the CTMs constructed by the three examiners were measured. To assess the construction reproducibility of CTMs, intraclass correlation coefficient (ICC) assessments were performed.

RESULTS

The ICC values of mesiodistal angulation and buccolingual inclination among the 3 examiners showed excellent agreement (0.950-0.992 and 0.965-0.993; 0.976-0.994 and 0.973-0.995 in the maxillary and mandibular arches, respectively).

CONCLUSIONS

The CTM showed excellent construction reproducibility in mesiodistal angulation and buccolingual inclination regardless of the construction skill and experience levels of the examiners.

摘要

目的

评估由口内扫描冠和锥形束计算机断层扫描（CBCT）扫描牙根组成的复合牙模型（CTM）的构建可重复性。

方法

该研究评估了15名年轻成年患者的240颗牙齿（上颌和下颌牙弓各有30颗中切牙、30颗尖牙、30颗第二前磨牙和30颗第一磨牙），这些患者有治疗前的口内扫描和CBCT数据。主考官（有3年CTM构建经验）以及考官A和考官B（无经验）通过执行以下步骤独立构建个体CTM：图像采集并处理成三维模型、整合口内扫描冠和CBCT扫描牙、用口内扫描冠替换CBCT扫描冠。测量了三位考官构建的CTM在近远中角度和颊舌倾斜方面的牙轴角度。为评估CTM的构建可重复性，进行了组内相关系数（ICC）评估。

结果

三位考官在近远中角度和颊舌倾斜方面的ICC值显示出极好的一致性（分别为0.950 - 0.992和0.965 - 0.993；在上颌和下颌牙弓中分别为0.976 - 0.994和0.973 - 0.995）。

结论

无论考官的构建技能和经验水平如何，CTM在近远中角度和颊舌倾斜方面均显示出极好的构建可重复性。
