The thickness of the bone, the height and the local abnormality are determined and are presented the measures of attenuation of the bone. Moreover, the surgeon can manipulate the implantations shown graphically to allow to a more necessary election on the size of the implantation and its orientation as well as one better appreciation and esteem of the reconstruction necessities, as an increase for enxerto sseo. Still for the related authors, the jaw presents a complex and three-dimensional anatomy. The seio to maxilar is central with projections delinquents extending itself in the bone frontal, zigoma and in the palatal bone. An inferior extension, the alveolar rim, is the component throughout teeth. The important regional control points include the spine to maxilar previous, the inferior recess of the seio to maxilar and the wooden floor of fossa nasal. Ducto nasopalatino is one previous crack that if extends of the wooden floor of the nasal socket to the palato.
The surfaces of the jaw are related as palatinas surfaces (palato) and face. On the other hand Snows (2001) emphasized that the contours of the alveolar arches and the localization of the inferior alveolar nerve are the more important anatomical references for the surgeon. The compression of the nerve for the implantation can result in sensorial disfuno of the inferior lip and teeth. The mandibular canal can be visualized in two intra-verbal and panoramic radiogrficas dimensions, which do not demonstrate, however, the position of the nerve in the buco-lingual direction. The buco-lingual position of the nerve can be demonstrated only in tomographic cuts in the plans axial and sagittal. The knowledge of the correct anatomical position of the inferior alveolar canal cannot compromise the surgical result. The beam to neurovascular alveolar inferior can be seen in the sagittal section of the jaw in its medium portion or throughout the internal rim of the cortical vestibular contest or lingual.
