Abstract

Mandibular movement recording is relevant for the planning and evaluation of mandibular function. These movements can include mandibular border movements (MBM) or mastication. Our objective was to characterize the kinematics of MBM and mastication among skeletal classes I, II, and III in the three spatial planes. A descriptive cross-sectional study was conducted with 30 participants. Instructions were provided on how to form Posselt's envelope and to perform masticatory. After data processing, we obtained numerical values for the areas, trajectories, and ranges of MBM that formed Posselt's envelope and the values for speed, masticatory frequency, and the areas of each masticatory cycle. Significant differences were found in the area of Posselt's envelope in the horizontal plane between skeletal classes I and III and in the range of right laterality between skeletal classes II and III. Mastication showed significant differences in the area of the masticatory cycles in the horizontal plane between classes I and III and between classes II and III. In conclusion, there were differences in MBM and mastication between skeletal classes III and I in the horizontal plane. This study supports the need to establish normal values for mandibular kinematics in skeletal class III.

摘要

下颌运动记录对于下颌功能的规划和评估具有重要意义。这些运动可包括下颌边缘运动（MBM）或咀嚼运动。我们的目的是在三个空间平面上描述I类、II类和III类骨骼患者的MBM和咀嚼运动的运动学特征。对30名参与者进行了描述性横断面研究。我们提供了关于如何形成波塞尔轨迹包络以及如何进行咀嚼运动的指导。经过数据处理，我们获得了构成波塞尔轨迹包络的MBM的面积、轨迹和范围的数值，以及速度、咀嚼频率和每个咀嚼周期面积的值。在I类和III类骨骼患者之间，发现波塞尔轨迹包络在水平面的面积存在显著差异，在II类和III类骨骼患者之间，右侧偏斜范围存在显著差异。咀嚼运动在I类和III类以及II类和III类之间，咀嚼周期在水平面的面积存在显著差异。总之，III类和I类骨骼患者在水平面的MBM和咀嚼运动存在差异。本研究支持有必要建立III类骨骼患者下颌运动学的正常值。
