A statistical comparison of cross-sectional cephalometric records of Class III malocclusion subjects from ages 5–15 with serial Class I controls, finding strong tendencies for early appearance of distinctive characteristics.
A clinically oriented presentation on growth mechanisms and the influence of posture and cellular communication on mandibular growth, with clinical illustrations.
Continuous anterior and vertical displacement of the rat mandible produces an increase in area of the resting zone and accelerated ossification of the hypertrophic zone. These responses differ greatly from those reported with intermittent displacement. They may be transient, or they may be an expression of accelerated maturation.
A cephalometric study finding significant associations between variations in facial pattern and three measurements commonly used to evaluate apical base relationships (the horizontal distance between points A and B, and angles A-N-B and A-B/Occlusal plane).
Fifty patients treated with Fränkel and fifty treated with Edgewise appliances are compared, finding Edgewise more effective in maxillary retraction and torque control, and Fränkel producing less undesirable lip retraction.
