Abstract

This purpose of this research was to examine the stability of normal occlusion during the transition from primary to permanent dentition. The sample consisted of 128 children (83 boys and 45 girls) 4.5 to 5.5 years old with normal occlusion in the primary dentition. The subjects were reexamined at 12.5 to 13.5 years. None had received orthodontic treatment. Although all the subjects had normal occlusion in the primary dentition, 72.7% (73.5% boys and 71.1% girls) had developed anomalies following eruption of the permanent teeth. These anomalies included crowding, Class II Division 1 or Class II Division 2 malocclusion, mesial occlusion complex, lateral crossbite, anterior crossbite, premature tooth loss, openbite or other anomalies.

摘要

本研究的目的是检查从乳牙列到恒牙列过渡期间正常咬合的稳定性。样本包括128名4.5至5.5岁乳牙列咬合正常的儿童(83名男孩和45名女孩)。这些受试者在12.5至13.5岁时接受了重新检查。没有人接受过正畸治疗。尽管所有受试者乳牙列咬合正常,但72.7%(男孩73.5%,女孩71.1%)在恒牙萌出后出现了异常。这些异常包括牙列拥挤、安氏II类1分类或安氏II类2分类错牙合、近中咬合复合体、单侧后牙反牙合、前牙反牙合、过早失牙、开牙合或其他异常。
