[Two case reports of maxillary prognathism. Some considerations of treatment for different facial type cases].
Generally, prognathism has been just identified as a large overjet. However, for the purposes of treatment, it should be noticed that different facial types are included in this malocclution. Facial pattern is classified into 2 groups; dolico and brachio facial types. The dolico facial type is generally a high angle case. It has a weaker natural anchorage than the brachio facial type. Consequently, it has a downward component in its mandibular growth. The classification of the two different facial types of maxillary prognathism would influence orthodontic treatment. When deciding on the treatment, the differences between the two facial types--in type of anchorage, growth direction, and control of toothaxis--should be taken into account.
