将下颌置入一三维空间坐标系中,下颌运动时各点位移通过传感器转换为电信号,进入自动电测系统。在一系列的坐标转换之后,下颌各区、各方向的位移以图形和数据的形式精确再现,这就是下颌运动自动描记系统的基本原理。本文选择22～27岁(平均24岁)男性11人,经临床及肌电检查确认口颌系统的形态及功能正常。选择双髁突区、6|6牙尖、下切牙切点作为观测点,分别记录各区在保持验接触(有牙接触)和脱离(牙合)接触(无牙接触)的情况下
The mandible into a three-dimensional space coordinate system, mandibular movement of the displacement of each point through the sensor into electrical signals into the automatic measuring system. After a series of coordinate transformations, the displacement of each area of the mandible and each direction is accurately reproduced in the form of figures and data. This is the basic principle of the automatic tracing system of mandible. In this paper, eleven men and women aged 22 to 27 years (average 24 years old) were selected. Clinical and EMG examination confirmed that the morphology and function of the oral maxillary system were normal. The bi-condylar region, 6 | 6 cusp, and the incision of the incisors were selected as the observation points. The records of each area were recorded under the condition of keeping the anterior contact (with and without an occlusal contact)
