简要总结
Recording mandibular movements plays an important role in stomatognathic system diagnosis and has been the subject of numerous research projects. This study presents theoretical assumptions and a practical solution in the form of a novel method of mandibular motion assessment.
详细描述
In the presented method, mandibular movements are recorded by a mono vision system where a digital camera is fixed on a special extension arm attached to patient's head. During movement the camera records changing positions of two markers placed on two selected two points on a patient's face. With such data, it possible to assess the absolute range of mandibular abduction as well as displacements from optimal trajectory occurring during movement, which indicative of stomatognathic dysfunctions.

结局指标
主要结局
Normalized displacement in frontal plane [mm^2/s]
时间窗: about 2 minutes
The value of normalized displacement calculated by dividing the sum of squared errors in movement trajectory on the transverse axis by the number of measurements taken during analysis time.
Range of mandibular abduction [mm]
时间窗: about 2 minutes
The maximum mouth opening value calculated as the difference in the distance between the markers before registration and during the maximum opening.
Maximum displacement in frontal plane [mm]
时间窗: about 2 minutes
The value of the maximum deviation of the lower marker in relation to the upper one in the frontal plane.
