 note = {application/pdf, The dry skulls of two adult female Japanese macaques were used in this study of bone strains produced by corticotomy combined with orthopedics. The directions and magnitudes of the principal strains were measured using an eight-pair triaxial strain gauge rosette. While compressive strains were seen in the control study (orthopedic force alone before corticotomy), tensile strains were seen in the experimental study (orthopedic force after corticotomy) on the frontzygomatic suture, the lateral side of the zygomaticomaxillary suture of the zygomatic bone, and on the maxillary bone. Corticotomy, combined with the posterior transfer of the anterior segment, had the following effects : in the control study, traction was diffused though the maxillofacial structures, while in the experimental study, it did not readily diffuse because the compact bone was separated. This resulted in favorable conditions for the posterior transfer of the anterior maxillary segment between the maxilla proper and the maxillary alveolar bone which are connected only by trabecular bone. These results demonstrate the usefulness of combining a corticotomy with retraction of the maxillary anterior segment by orthopedic forces. A clinical case of Class II malocclusion is presented to illustrate what can be accomplished with treatment by corticotomy. The treatment objectives were achieved with improvement in the patient's profile and in the function and esthetics of the dentition.},
