[Active canine tooth movement by spongiosa graft in bilateral cheilognathopalatoschisis].

Bone grafting in the alveolar cleft offers a bony support in the alveolar process for the erupting canines and should be performed before the eruption of the teeth starts. Although bone grafting is done in time, the eruption of the canines does not always follow spontaneously. This is why a simultaneous ligation of the canines is sometimes indicated. The ligature can be threaded through the bone graft. Active eruption of the canines can begin eight weeks post operation. This procedure ensures a proper alignment of the canines in a well-defined processus alveolaris. The method is demonstrated in a bilateral cleft lip and palate patient.
