[Biometric data using follow-up x-ray computed tomography of the morphological and structural changes of mandibular bone reconstructions using hydroxyapatite-collagen-GAG].

The use of biomaterials for bone reconstruction raises the problem of their architectural and structural outcome. CT makes an accurate biometric follow-up possible. The association of HA, collagen and GAG appears to be a reliable substitute for bone, owing to the permanence of the dimensional results and to the structural evolution that seems to finally provide total structural restoration.
