Change of premaxilla and mandible were interacted to the quality diet (Renaud and Michaux, 2003, 2007; Duarte et al., 2000; Renaud and Millien, 2001), varieties of ventral of the cranium and mandible had effects on Dimension 2, which may imply that E.
Radiographs of the mass revealed an irregularly shaped bony opacity proliferating from the dorsal premaxilla (Fig 1).
One of the reported cases was associated with an impacted left central incisor (21) in the premaxilla. Treatment proposed was total enucleation of lesion with upper central incisor extraction [13].

Bilateral cleft lip and palate is a congenital deformity in which the premaxilla is suspended from the tip of the nasal septum and posterior alveolar segments and lateral lip tissues remain behind (Figure 1) (1).

The most ideal location for implants in edentulous total maxillectomy patients is residual premaxilla. Zygomatic implants are also used in the treatment of maxillary defects secondary to trauma, tumour resection or any congenital defects.
The ANB angle is formed with the vertex at point N (nasion, the most anterior aspect of the frontonasal suture, located by visual inspection on the tracing) and two sides respectively extending to A point (the deepest point on the contour of the premaxilla) as well as B point (the deepest point on the contour of the mandible)5.
Premaxilla is the most affected area with regard to its particular anatomical conditions that predispose to increased exposure trauma.
