To evaluate the dental arch dimensions in 6-year-old boys with unoperated submucous cleft palate (SMCP), and to compare their dental arch dimensions with those of boys without clefts and boys with clefts of the soft palate (CP).
The sizes of dental arches in 97 boys were compared retrospectively from dental casts taken at a mean age of 6.4 years (range 5.2-8.4). The material included 34 boys without clefts, 30 with unoperated SMCP, and 33 with CP. In children with CP, palatal closure had been done by the pushback technique at a mean age of 1.5 years.
The dental arch dimensions of the boys with SMCP were similar to those of boys without clefts, except for a decreased maxillary arch length. There was no difference in maxillary arch length between the boys with SMCP and those with CP. The boys with CP had smaller maxillary and mandibular dental arch widths than the boys without clefts and with SMCP. There were no differences in the number of boys with permanent incisors between the three groups.
Six-year-old boys with unoperated SMCP have similar dental arch dimensions as boys without clefts, except for a decreased maxillary arch length.
评估未接受手术治疗的黏膜下腭裂（SMCP）6岁男孩的牙弓尺寸，并将其牙弓尺寸与非腭裂男孩及软腭裂（CP）男孩的牙弓尺寸进行比较。
回顾性比较97名男孩在平均年龄6.4岁（范围5.2 - 8.4岁）时所取牙模的牙弓大小。材料包括34名非腭裂男孩、30名未接受手术治疗的SMCP男孩和33名CP男孩。对于CP患儿，平均在1.5岁时采用后推技术进行腭部闭合。
除上颌牙弓长度减小外，SMCP男孩的牙弓尺寸与非腭裂男孩相似。SMCP男孩与CP男孩在上颌牙弓长度上无差异。CP男孩的上颌和下颌牙弓宽度比非腭裂男孩和SMCP男孩小。三组之间恒牙切牙的男孩数量无差异。
未接受手术治疗的SMCP 6岁男孩的牙弓尺寸与非腭裂男孩相似，除了上颌牙弓长度减小。
