Complete breakage of three-dimensional miniplates: unusual complication of osteosynthesis after sagittal split osteotomy. Two case reports.
We describe two cases in which three-dimensional miniplates broke after bilateral sagittal split osteotomy. The miniplates broke vertically and the cause was suspected to be excessive shear force on the osteotomy line because of unstable occlusion. In patients with unstable postoperative occlusions the osteosynthesis should be bicortical.
