Abstract

A method was described in Part I in which mandibular border movements of a subject can be compared with the movements generated by various articulators (fully adjustable Denar SE and semiadjustable Denar Mark II) by using an electronic pantograph, the Pantronic. The mean values of 12 sets of plots from this device were calculated and graphs were generated. For the subject studied, differences were detected by the Pantronic pantograph between human border movements and those generated by each articulator and method of adjusting it. In the horizontal table, the semiadjustable articulator without immediate side shift always showed the potential of greater errors, especially as excursions started. When the semiadjustable instrument was programmed with immediate side shift, its movements were comparable with the fully adjustable articulator. Neither articulator exactly simulated the subjects' movements.

摘要

第一部分描述了一种方法，通过使用电子面弓Pantronic，可将受试者的下颌边缘运动与各种咬合架（完全可调的Denar SE和半可调的Denar Mark II）产生的运动进行比较。计算了该设备12组图的平均值并生成了图表。对于所研究的受试者，通过Pantronic面弓检测到人体边缘运动与每个咬合架及其调整方法所产生的运动之间的差异。在水平方向上，没有即时侧移的半可调咬合架总是显示出更大误差的可能性，尤其是在偏移开始时。当为半可调器械编程使其具有即时侧移时，其运动与完全可调咬合架相当。两种咬合架都没有精确模拟受试者的运动。
