Cephalometric Evaluation of Cranio-Facial Skeletal Growth by Jarabak Analysis

Abstract

Jarabak analysis based on Björk analysis has been modified and added as a part of Tweed, Steiner and Ricketts analysis, as well as others. The main features of this method are that it can be divided into skeletal and denture components, and growth direction can be analyzed in detail by the skeletal component. It is recognized as an optimal cephalometric analysis for tracing cranio-facial skeletal growth.
We investigated and traced the growth changes in the cranio-facial skeleton from childhood to adolescence in 15 boys and 14 girls between 10 and 15 years of age using Jarabak analysis, taking cephalometric radiographs once a year for six years. Average values and annual increments were obtained for the Jarabak analysis of this group of Japanese children.
We found that the Japanese cranio-facial growth pattern either had a slight inclination from the straight downward type or tended to the counterclockwise growth type.
