An analysis and quantitation of protrusive and retrusive mandibular movement is provided. This report is one study along with four other parts analyzing the mandibular opening movement, the transversal shift during protrusion and retrusion, the mediotrusive movement and mastication. Protrusive movements of 225 individuals (180 patients, 45 volunteers) were analyzed using computerized axiography. Investigating both asymptomatic volunteers and patients with abnormal joint mobility helps to improve evaluation of these abnormalities. With the aid of diagnostic computer software, the length of the pathways was measured and the characteristics of the curves were analyzed. An average group was defined based on the values found in asymptomatic individuals, comprising 50% of our volunteers. The interquartile range for the male volunteers was 8.79-12.27 mm for the right joint and 9.43-12.93 mm for the left joint; for female volunteers it was 8.32-10.64 mm and 9.2-11.26 mm, respectively.
本文对下颌前伸和后缩运动进行了分析和定量研究。本报告是一项研究，另外还有四项研究分别分析了下颌开口运动、前伸和后缩过程中的横向移位、侧方运动和咀嚼运动。使用计算机轴面断层摄影术对225名个体（180例患者和45名志愿者）的前伸运动进行了分析。对无症状志愿者和关节活动异常的患者进行研究，有助于改善对这些异常情况的评估。借助诊断计算机软件，测量了运动轨迹的长度，并分析了曲线特征。根据无症状个体的测量值定义了一个平均组，该组占我们志愿者的50%。男性志愿者右侧关节的四分位距为8.79 - 12.27毫米，左侧关节为9.43 - 12.93毫米；女性志愿者右侧关节的四分位距分别为8.32 - 10.64毫米，左侧关节为9.2 - 11.26毫米。
