摘要
头颈部、牙列和颞下颌关节的软硬组织是正颌手术计划的决定因素。治疗开始时颌骨与最终位置之间关系的准确性和精确性取决于准确的牙列记录。本研究的目的是根据临床适用性、技术难度、有效成本、准确性和精密度,确定最简单可行的三维正颌规划虚拟牙模型转移方法。在患者的上下颌骨石膏模型中放置了10个球形瓷标记。使用口内光学扫描仪、口外数字模型扫描仪和锥束计算机断层扫描对模型进行扫描。为了评估可靠性,每个测量每隔一周重复10次,并测量点之间的距离水平和垂直。使用IBM SPSS Statistics 2.2程序对研究结果进行统计评估。口腔外模型扫描仪与数字卡尺法测量结果无显著差异(P > 0.05),而数字卡尺法与其他方法之间存在显著差异(口腔内三维扫描仪P = 0.000;CBCT p = 0.001)。虽然所有的测量结果在所有方法中显示出高度的一致性,但口腔外数字模型扫描仪获得的结果最准确。(r = 0.99, P = 0.01, P < 0.05)。
Comparing the accuracy and precision of digital model transfer methods used in virtual orthognathic planning
The hard and soft tissues of the head and neck, dentition, and temporomandibular joint are the determining elements in orthognathic surgery planning. The accuracy and precision of the relationship between the jaws at the beginning of treatment and their final position depend on an accurate dentition record. The aim of this study was to determine the simplest and most feasible virtual dental model transfer method for three-dimensional orthognathic planning according to clinical applicability, technical difficulty, effective costs, accuracy, and precision.
A total of ten spherical porcelain markers were placed in plaster models of the maxilla and mandible of a patient. The models were scanned using an intraoral optical scanner, an extraoral digital model scanner, and cone-beam computerized tomography. To evaluate reliability, each measurement was repeated 10 times at 1-week intervals and the distances between points were measured horizontally and vertically. The findings obtained in the study were evaluated statistically using IBM SPSS Statistics 2.2 program.
Measurements obtained with the extraoral model scanner did not differ from the digital caliper method (P > 0.05), while there were significant differences between the digital caliper and the other methods (intraoral 3D scanner P = 0.000; CBCT P = 0.001).
Although all of the measurements showed high consistency among all methods, the most accurate results were obtained with the extraoral digital model scanner. (r = 0.99, P = 0.01, P < 0.05).
