Clinical investigation and details of four cases of skeletal class I patients who received simultaneous repositioning of the maxilla and mandible are reported in this paper.<BR>Indications for simultaneous two-jaw surgery for select class III dentofacial deformities are also discussed.<BR>The restoration of normal jaw function, optimal facial esthetics and long term stability is the sine qua non of successful corrective surgery to class I dentofacial deformities.<BR>The keys to this are accurate three dimensional analysis, planning and surgery based on foundations of clinical, biological and biomechanical examination. The following four groups of select class I dentofarial deformities qualify for simultaneous two-jaw surgery: (1) severe class I dentofacial deformities without vertical and transverse deformities, (2) class jil dentofacial deformities with vertical maxillary excess, (3) class III dentofacial deformities with vertical maxillary deficiency and (4) class I dentofacial deformities with maxillary asymmetry.<BR>However, group (1) was small. The majority of class III dentofacial deformities requiring simultaneous two-jaw surgery were types (2), (3) and (4).
