Late management of secondarily grafted clefts.

34 patients (40 sides) received alveolo-palatal bone grafts for closure of the residual cleft, thus guiding a lateral incisor or canine into the arch. Long-term follow-up shows that in 41% of the patients uninterrupted arches were achieved with a normal relationship by orthodontic treatment only. 38% needed segmental osteotomies to eliminate the edentulous space, and in only 20% were bridges made to restore the dental arch. 9 (25%) patients still required a Le Fort I advancement osteotomy, despite optimal orthodontic treatment. The use of segmental osteotomies for eliminating edentulous spaces in cleft palate patients is discussed, and their advantage in relation to nasal base support is emphasized. It should be the aim to achieve in every cleft palate patient a complete archform without the need for bridges or removable prostheses. A rational orthodontic-surgical approach to the cleft, lip and palate patient is suggested with respect to naso-maxillary growth and development.
