[Predicting of growth tendency with cephalometry. Cephalometric research comparing orthodontic treatment cases with...

The Hasund cephalometry gives important information about the position of the mandible and maxilla to each other and to the cranium in horizontal and vertical plane, and about the expecting mandibular growth. The aim of the study was to examine the reliability of the Hasund growth analysis on the basis of cephalogramms. The data of eighteen children having been treated with four premolar extraction in the growing period were compared. At the start of treatments the children's average age was 10 (8.5-11.5) years. Figures from the cephalometry were analysed by an orthodontic diagnostic program. According to our results the predicted growth was justified in 14 cases and contrary mandibular development was found in 4 cases. Beyond the limits of this study we concluded that the Hasund growth analysis gives mainly a reliable prognosis on predicting mandibular development. In diagnostic procedures this analysis should be followed for a successful decision-making in treatment plan. However, during the orthodontic treatment the prognostic results have to be monitored by using further cephalometric evaluations in a time-scales of a year.
