Abstract: Severe skeletal malocclusions with facial prognathism keep high prevalence in Chinese population. The classification and diagnosis of these malocclusions remain challenging due to the complicity and variety in their clinical manifestations, cephalometric morphologies and perceived etiologies. Based on elaborated studies about the extensive clinical archives and records, this article introduced an innovative classification of this specific anomaly, which not only provides with diagnostic specifics, but also indicates the possible etiologies and therapeutic guidance.
