The bone tissue loss occurs in the alveolar region but can enlarge to the basal bone. The seriousness of the bone tissue loss relies on the space taken up by the roots prior to the tooth disappearance.
In that sense a complete bone tissue loss most commonly happens in the molar areas where only the basal bone remains under the sinuses.
On the other hand, the loss of monoradicular teeth first affects the external table as the lingual wall and especially palatines, which are thicker and more mineralized.
The bone wasting is mostly horizontal for the incisivocanine region and vertical for the posterior sectors.
The defect's importance varies according to its seniority and to the patient's background. No prognosis on a bone tissue can be achieved after an extraction.
Following the residual bone form, a clinical evaluation, a 3D X-ray (cone beam) and a pre-implantory study (with an implant and prosthodontic inserting simulation) will be performed on the tissue loss.
