[The osteoplastic care of the cleft jaw--an advance for the orthodontic treatment of cleft patients?].

This survey deals with problems of osteoplastic supply of the cleft from the orthodontic point of view. Remarkable parallels exist between primary and secondary osteoplasty: The involution stability of the alveolar process is only presented in a space-less tooth line. Therefore, the primary goal is to guarantee tooth eruption in the former cleft area. However, the antalogous bone graft in the former cleft area has to have a similar structure as adjacent alveolar bone. If tooth germs pass through the bone graft, an own parodont can be built up in the course of eruption. This is applicable to both dentitions. Accordingly, the osteoplasty of clefts is the most important prerequisite for stable treatment results and a healthy dentition.
