[Secondary sliding of the mandible after sagittal osteotomy of the ascending ramus].
Thus in the area of prognathism, modifications would seem to develop during the first three months after deblocking:-true recurrences are rare and would appear to be avoidable by careful technique;-secondary sliding shoud not be the source of too much anxiety, being the result of spontaneous attempts at equilibrium and are of little aesthetic consequence. Our statistics indicate that sagittal osteotomy of the ascending rami gives 82% good results. This would agree with statistics generally found in the literature.
