本文介绍一种实用的牙颌模型立体摄影测量系统及该系统的组成、工作程序及新型参数计算的内容和使用方法。经对100例牙颌(正常(牙合)、异常(牙合))模型资料的摄影测量;参数计算、统计分析等多项试验表明:运用此系统能获得许多反映牙颌形态结构特征——牙弓、齿糟座、(牙合)曲线、牙齿倾斜角等大量数据和图形,以及它们之间关系的定量分析结果。这不仅有助于提高口腔医学临床诊断,基础理论研究水平,而且还提供了一种精密、高效的测量技术及较为理想的保存牙颌模型资料的新方法。
This article describes a practical dental jaw stereoscopic photogrammetry system and the composition of the system, working procedures and the calculation of new parameters and methods of use. A total of 100 cases of dental (normal occlusion, abnormal occlusion) model data of photogrammetry; parameter calculation, statistical analysis and many other experiments show that: the use of this system can be obtained to reflect many of the characteristics of dental structures - Dental arch, bad tooth seat, (occlusion) curve, tooth tilt angle and other large amounts of data and graphics, as well as quantitative analysis of the relationship between them. This not only helps to improve the clinical diagnosis of stomatology, basic theoretical research, but also provides a sophisticated and efficient measurement techniques and a more ideal method of preservation of dental model data.
