Skeletal Class III malocclusion may be characterized by a prognathic mandible , retrognathic maxilla and / or a combination of the two. This sagittal dysmorphia is further magnified as it encompasses vertical and transverse problems which get aggravated most often with the fourth dimension of time. Longitudinal growth studies conducted by numerous researchers in different parts of the world has established the fact that the morphologic pattern of skeletal Class III is established early in life and maintained thereafter. Once established, the annual growth increments are quite similar to that of Class I individuals. Meanwhile, the dentoalveolar disharmony is aggravated and becomes more severe during this period.
