The aim of this study was to describe maxillary and mandibular dental-arch form and occlusion in bilateral cleft of the lip and palate (BCLP) from 3 to 17 years of age and to compare their characteristics with a normative sample. A sample of 22 patients with BCLP was investigated, with a noncleft control sample used for comparison. Dental-arch dimensions were studied on dental casts. A comparison between both groups was made at fixed time intervals. From 9 years of age, the cleft sample showed a significantly smaller maxillary depth. Maxillary dental-arch widths were also significantly smaller than in the control group over the whole age period. Mandibular dental-arch measurements were very similar in both groups, although smaller first-molar widths were noted in the BCLP group beginning at 12 years of age. A tendency for end-to-end occlusion was found, which became more clear with age and was most markedly in the canine region.
本研究的目的是描述3至17岁双侧唇腭裂（BCLP）患者的上颌和下颌牙弓形态及咬合情况，并将其特征与正常样本进行比较。对22例BCLP患者样本进行了调查，并使用非腭裂对照样本进行比较。在石膏模型上研究牙弓尺寸。两组在固定时间间隔进行比较。从9岁起，腭裂样本的上颌深度明显较小。在整个年龄段，上颌牙弓宽度也明显小于对照组。两组下颌牙弓测量值非常相似，尽管在12岁开始，BCLP组的第一磨牙宽度较小。发现有端对端咬合的趋势，随着年龄增长这种趋势变得更加明显，在尖牙区最为显著。
