KREIA, Tatiana Banzatto et al. Type of facial growth trend in orthodontics and dentofacial orthopedics. RGO, Rev. gaúch. odontol. (Online) [online]. 2011, vol.59, suppl.1, pp. 97-102. ISSN 1981-8637.

The knowledge of the facial growth trend is very important in orthodontic treatment. A lateral headfilm is recommended in all young patients undergoing a preorthodontic guidance program to anticipate the best time to begin any mechanical procedures and the possibilities to determine the type of facial growth trend. In type A it will be observed that the middle and lower face are growing forward and downward in unison, with no change in ANB angle. Type B growth trends reveals that growth is downward and forward, with the middle face growing forward more rapidly than the lower and in type C the lower face is growing downward and forward more rapidly than the middle face revealing a decrease in the size of the ANB angle.
