There are two leading hypotheses concerning maxillofacial morphogenesis in human (Fusion Hypothesis & Overlapping Hypothesis). Differing opinions about the maxillary morphogenesis lead to different concepts about the intrinsic arterial supply to the maxilla. This research was to study the arterial constitution of human maxilla so as to inquire into its morphogenetic patterns. Appropriately perfused (Pb3O4 + turpentine) infraorbital and posterior superior alveolar arteries in 9 fresh human cadavers with ages ranging from 2 days to 35 years revealed that 4 individuals' arterial systems of maxilla consisted of anterior and posterior superior alveolar arteries, but the other 5 ones consisted only of the posterior superior alveolar artery, which extending to the facial midline and supplies all the incisor and molar teeth. The results indicated that two kinds of maxillary morphogenesis patterns may exist simultaneously.
