我们已经研制出一个用于齿科矫形治疗中测量三维口齿模型侧面图和三维牙运动的系统。侧面图的测量是基于用图象探测设备检测激光在口齿模型上的运动的三角学方法。该系统采用计算机控制并被设计成在25mm的深度范围内使深度和水平分辨率分别达到0.05mm和0.1mm的系统。我们已经使用该系统测量了在齿科矫形治疗中包括旋转在内的牙齿的三维运动。运动图形的获得是通过计算机处理将治疗中不同阶段依次得到的口齿模型的各个侧面 We have developed a system for measuring side views and 3D tooth movements in orthodontic dental applications. The side view measurement is based on the trigonometry method of detecting the movement of the laser on the tooth model using the image detection apparatus. The system uses a computer-controlled system designed to achieve depth and horizontal resolution of 0.05 mm and 0.1 mm, respectively, over a depth of 25 mm. We have used this system to measure the three-dimensional movement of teeth, including rotation, during orthodontic treatment. Motion graphics obtained by computer processing will be treated at different stages in turn get all the sides of the dentition model
