OBJECTIVE
Comparison of the use of two-dimensional (2D) and three-dimensional (3D) images for rating dental arch relationships.
MATERIALS AND METHODS
The sample consists of pretreatment dental casts, 2D photographs, and 3D images of 70 patients with unilateral complete cleft lip and palate. Two experienced examiners used the Goslon Yardstick to rate dental arch relationships. The ratings were done three times for all groups. Weighted kappa statistics were used to evaluate intra- and interrater agreement and the agreement between the groups.
RESULTS
Intra- and interexaminer agreement were high for all groups (between 0.86 and 0.96), indicating very good reproducibility. The mean Goslon scores ranged between 2.84 and 2.90.
CONCLUSION
2D and 3D imaging of dental casts provides a valid alternative for actual study models for rating dental arch relationships.
目的
比较二维（2D）和三维（3D）图像在评估牙弓关系中的应用。
材料与方法
样本包括70例单侧完全性唇腭裂患者的治疗前牙模、二维照片和三维图像。两名经验丰富的检查者使用戈斯隆标尺评估牙弓关系。所有组均进行三次评估。采用加权kappa统计量评估检查者内和检查者间的一致性以及组间一致性。
结果
所有组的检查者内和检查者间一致性均较高（在0.86至0.96之间），表明具有很好的可重复性。戈斯隆平均得分在2.84至2.90之间。
结论
牙模的二维和三维成像为评估牙弓关系的实际研究模型提供了有效的替代方法。
