OLATE, Sergio et al. Comparison of Bone Graft Healing Between Autogenous Bone, Blood Clot and Anorganic Bovine Bone Matrix: Radiographic and Histological Analyses. Int. J. Morphol. [online]. 2013, vol.31, n.4, pp.1257-1262. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022013000400018.

Surgical procedures involving the rehabilitation of the maxillofacial region frequently require use of bone grafts. Bone graft follow-up is generally done through clinical analysis and especially through image tests, although few studies specifically correlate both. The object of this research was to establish a relation between radiographic exams and the bone repair process stage in created defect with autogenous bone, blood clot and anorganic bovine bone matrix. Three 8 mm diameter defects were performed in the parietal bone of 6 male adult beagle dogs, choosing the selected graft for each defects; 3 and 6 week period were used for radiographic and histological analyses. The result show that autogenous bone and blood clot were similar between histological and radiograph analyses; for heterogeneous bone was present areas described how bone in radiograph that were residual particles in histological exam. We concluded that radiographic tests could be used as a parameter for reconstruction follow-up only when autogenous bone graft is used.
