Mandibular lateral displacement (MLD) is a result of temporarily accelerated growth of unilateral condyle. Structure of lower face of typical mandibular lateral displacement malocclusion was analysed by means of modified denture frame analysis. Results of measurement indicated that noteworthy present on difference of maxillary occlusal plane between right and left dentitions. It suggested that the MLD malocclusion result from unilateral elongation of the molars due to posterior discrepancy and functional displacement of mandible associated with the differential condylar growth.
下颌侧方移位（MLD）是单侧髁突暂时加速生长的结果。采用改良义齿架分析法分析了典型下颌侧方移位错牙合的下面部结构。测量结果表明，左右牙列的上颌牙合平面存在显著差异。这表明，MLD错牙合是由于后牙差异导致磨牙单侧伸长以及下颌与髁突生长差异相关的功能移位所致。
