We present a case report of remarkable skeletal mandibular protrusion operated with Le Fort I osteotomy and sagittal splitting ramus osteotomy, the so-called twojaw surgery. In Le Fort I osteotomy, positioning of the maxillary bone was performed using a face bow transfer method. As a result of the osteotomy, the maxillary bone segment was fixed at the planned position. The surgical procedures achieved an improvement in the facial form and the occlusion. In this case, an absorbable bone fixation plate, FIXSORB<SUP>®</SUP>MX, was employed and it could be as useful for two-jaw surgery as a titanium plate under equal conditions. The progress after the operation was evaluated. Although skeletal changes were merely observed at one year after operation, the dental and skeletal stability was well maintained for three years after the operation.
