Contrarily, the panoramic one does not allow a good analysis of the ssea texture. This examination is, therefore insufficient in analysis daily pay-operatria for implantation, but indispensable for the interpretation of a scanogrfico examination. The Cat scan locates the explored zone and guides the interpretation in implantologia, evaluates the zone edntula and allows to look the planes of reference that are visualized on the succession of the cuts (side by side opposing tooth remaining of the zone edntula, alveolus of the extration, displacement of the dental mass, metallic restoration), thanks to these planes of reference the reading of scanner if it becomes easy accessible. Fredholm et al. (1993) they had evaluated, through panoramic and tomographic examinations, the examples of different alveolar Christians who if had become limitations of the panoramic technique, but that it is the only radiogrfica technique for daily pay-surgical evaluation of the places of implantations. The panoramic x-rays do not disclose to the form and the dimension of the aspect vestibule-lingual of the alveolar process. In other words, the panoramic x-ray does not offer information on all available sseo volume.

The same authors had told, that a ortopantomografia of great height of the alveolar crest normally indicates that the reabsoro in the direction vestibule-lingual is small or negligencivel. This allows that the Radiologist evaluates the ssea height as enough and thus she considers the unnecessary tomographic examination. The morphologic variations in the alveolar process constitute serious limitations and these morphologic variations are difficult to be disclosed in the examination physician or ortopantomogrfico.
