Facial soft tissues are a major determinant of treatment choice. When Class I and Class II malocclusions were compared using finite-element analysis, morphologic differences were localized and quantified. This study highlights the importance of determining the timing, magnitude and direction offacial growth prior to treatment to achieve stable results.

A cephalometric study using Downs' analysis was undertaken with lateral cephalometric radiographs for a mixed sample of 50 child, adolescent and young adult Indonesians who presented with Angle Class I occlusions. Significant differences between this study group and the published results from comparative racial types were found for Downs' angle of convexity, Y-axis and incisor inclinations, indicating that Indonesians can be differentiated from other races with similar occlusions by using Downs' analysis.
