Resumen

BELTRAN, Victor et al. Bone Healing in Transverse Maxillary Defects with Different Surgical Procedures Using Anorganic Bovine Bone in Humans. Int. J. Morphol. [online]. 2013, vol.31, n.1, pp.75-81. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022013000100011.

The centripetal resorption of maxilla is a continuous process after tooth loss. For treatment of deficient bone sites, autologous bone grafts may be used, as an alternative, biomaterials can be applied which do not require intra- or extraoral donor sites. The present report we describe the use of anorganic bovine bone (ABB) based on three case reports under different modes: Membrane, rigid barrier and connective tissue graft. Clinical results show that under all conditions, sufficient hard tissue was formed to allow implant born rehabilitation in the former insufficient bone sites. Histologic evaluation revealed trabecular bone in an almost mature matrix with resting particles of ABB. Depending on the original site situation, two step rigid occlusive barrier concept may be applied, if resting bone does not provide implant stability, whereas membrane covered augmentation in combination with connective tissue is recommended if simultaneous implant insertion is possible.
