Sažetak

Skeletal orthodontic anomalies, as wel as those having strongly manifested skeletal components, represent a remarkable problem from the aspect of treatment. Roendgencephalometric methods of craniofacial growth prediction, by using longitudinal studies, are not reliable because the growth pattern is strictly individual. Most
important, but impossible, is to predict the intensity and variations of pubertal growth spurt. Therefore, in some cases, the course of conventional orthodontic treatment must be changed, and a surgical procedure has to be considered.
A female patient of the Department of Orthodontics School of Dental Medicine, University of Zagreb, started her treatment at the age of 9, during the mixed dentition, when the diagnosis mandibular prognathism was foreseen. During a few years of treatment bionator and removable plates were applied. Nevertheless, in spite of
excellent collaboration, during puberty, because of remarkable acceleration of condylar growth, true mandibular prognathism was diagnosed. Surgical procedure was indicated. Therefore orthodontic treatment was focused on removal of dentoalveolar compenstory elements as well as previous treatment effects. By using a fixed appliance (Roth 0.018 system) normal inclination of the incisors was
achieved in both dental arches as well as congruence of transversal dimensions of both jaws, while the sagittal intermaxillary relationship was diagnosed as mandibular prognatism. After a detailed diagnostic procedure and computerised postoperation result vision, surgery intervention was done on the mandible by osteotomy with two
vertical and one horizontal cut. Bone surplus segment was removed. The fixation of skeletal segments was done by screws on both sides, whille the intermaxillary relation was obtained by the fixed appliance. Intermaxillary relation was provided by an interdental guide, made just before surgical treatment. During the retention period the previous fixed appliance was used, and after six months it was replaced by two removable retainers. The orthodontic-surgical treatment results confirmed the functional and esthetic demands foreseen by treatmen planning.
