[Growth in the width and length of the dental arch in children with unilateral cleft lip and cleft palate].

A study of casts of the dentitions of children with cheilognathopalatoschisis made over an extended period emphasizes that the development and the growth of the maxillary dental arch in width and length are considerably reduced as compared to children without clefts. Consequently, therapeutical measures must be taken to maintain the length and width of the maxillary dental arch.
