The correction and preservation of arch form in complete clefts of the palate and alveolar ridge.

A simple but effective means of guiding the cleft alveolar ridge into good contour of the upper dental arch is presented. When apposition of the alveolar ridge is achieved, the position is stabilized with a rib graft at from 4 to 9 months of age. The palate is not repaired until the bone graft is well fixed. The contour of the alveolar ridge in severe clefts is markedly improved over that previously achieved.
