 note = {It is important in clinical orthodontics to develop a simple and precise method for prediction of mandibular growth from data of lateral cephalograms. The purpose of this study was 1) to develop a basic template for mandibular growth registered at the A-point and 2) to analyze not only direction but also distance of mandibular growth in the same way. A converted profilogram superimposed at Point A using the FH plane as a reference axis was made from the conventional data of Sakamoto as the first step in this study. Next, the direction and distance of mandibular growth were measured between mandibular points of Pog on the converted profilogram at the initial and these at the retaining stage of orthodontic treatment. For this purpose, 20 sets of tracings of lateral cephalograms of 20 female orthodontic patients with maxillary protrusion were used. In summary, the mean value of the direction of the mandibular growth was 63.84 degrees (s. d. 50.11) and that the distance was 5.08mm (s. d. 3.40), indicating an annual increment of 0.91mm (s. d. 0.62). The correlation factors between the growth direction and the mandibular characteristic angles were analyzed, and the correlation factor to the value of the mandibular plane angle added to the Y axis angle was highest (r=0.739). The correlation factors between the growth distance and the mandibular characteristic lengths were also analyzed, and the mandibular ramus length (Ar-Go) divided by the mandibular length (Ar-Me) was highest (r=0.409). Simple and accurate prediction of mandibular growth in an orthodontic patient can be performed when the retrogression formula of the growth direction and distance from data in this study is applied., application/pdf},
