Köle's osteotomy, a follow-up study

A retrospective investigation into Köle's (1959) osteotomy for the correction of anterior open bite was performed. Changes in occlusion were seen in 32%. Bone graft incorporation was satisfactory. The vitality of the teeth adjacent to the osteotomy and the periodontal condition were satisfactory if a tooth at the osteotomy site was extracted. The sensibility of the lip was, in general, good.
