Slot osteosynthesis technique (SLOT) for sagittal ramus split osteotomies. A method to optimize occlusal control and condylar seating.
In the technique presented, a specially designed drill and bone holding forceps are used. These enable a horizontal slit to be cut in the condyle-bearing segment, at the site of the largest contact surface. One lag-screw is tightened in the centre of the slit at each side. By releasing the IMF (intermaxillary fixation) and untightening one or both screws, the condylar segments can be repositioned and the occlusion corrected before inserting the other tandem screws.
