The material of this study was included 117 dental casts taken from children with UCLP, 66 males and 51 females.1)Dentoalveolar arch was categorized in 8 forms including 4 compound forms.2)The anterior collapsed group showed a short dental arch length and large width / length ratio.3)The vertical growth of the alveolar region at the canine segment, showed an upward displacement in the lateral collapsed group. However, this displacement was little in the anterior collapsed group.4)A high incidence of crossbite, especially in the minor segment and canine regions was detected as well as an penbite related to the minor segment.5)These results suggested that reconsideration of the surgical procedures of the UCLP patient is necessary to overcome the remarkable dental arch collapse and deformity.

本研究材料包括117例儿童UCLP牙模，其中男66例，女51例。1)牙槽弓分为8种形态，其中复合形态有4种。2)前塌陷组牙弓长度短，宽长比大。3)侧塌陷组犬齿段肺泡区垂直生长呈向上位移。然而，这种移位在前路塌陷组很少。4)交叉咬合发生率高，特别是在小节段和犬齿区域，以及与小节段相关的penbite。5)这些结果提示，对于UCLP患者，需要重新考虑手术方式，以克服明显的牙弓塌陷和畸形。
