Evaluation of the effect of infant orthopedics (IO) on the occlusion of the deciduous dentition in patients with unilateral cleft lip and palate (UCLP).
Prospective, two-arm, randomized, controlled clinical trial with three participating cleft palate centers (Dutchcleft).
Cleft Palate Centers of the University Medical Center Nijmegen, Academic Center of Dentistry Amsterdam, and Dijkzigt University Hospital Rotterdam, The Netherlands.
Children with complete UCLP (n = 54) were included.
In a concealed allocation procedure, half of the patients was randomized to wear a plate till surgical closure of the soft palate (IO+), and the other half (IO-) did not have a plate.
Dental arch relationships were assessed at 4 and 6 years of age with the 5-year-old index; the Huddart-score; and measurements of overjet, overbite, and sagittal occlusion.
There were no significant differences found between the IO+ and IO- groups for the 5-year-old index; the Huddart-score; and overjet, overbite, and sagittal occlusion.
IO had no observable effect on the occlusion in the deciduous dentition at 4 and 6 years of age. Considering the occlusion only, there is no need to perform IO in children with UCLP.
评估婴儿整骨术（IO）对单侧唇腭裂（UCLP）患者乳牙列咬合的影响。
前瞻性、双臂、随机对照临床试验，有三个腭裂中心参与（荷兰腭裂研究）。
荷兰奈梅亨大学医学中心腭裂中心、阿姆斯特丹牙科学院学术中心以及鹿特丹迪克齐格特大学医院。
纳入完全性UCLP患儿（n = 54）。
在隐蔽分配程序中，一半患者随机分配佩戴矫治板直至软腭手术闭合（IO+），另一半（IO-）不佩戴矫治板。
在4岁和6岁时用5岁指数评估牙弓关系；Huddart评分；以及覆盖、覆合和矢状向咬合的测量。
IO+组和IO-组在5岁指数、Huddart评分以及覆盖、覆合和矢状向咬合方面未发现显著差异。
IO对4岁和6岁乳牙列的咬合没有可观察到的影响。仅考虑咬合情况，UCLP患儿无需进行IO。
