Histomorphometric evaluation of anorganic bovine bone coverage to reduce autogenous grafts resorption: preliminary results.

Maiorana C, Beretta M, Battista Grossi G, Santoro F, Scott Herford A, Nagursky H, Cicciù M - Open Dent J (2011)

Bottom Line: Such a situation in the past made overgrafting of the recipient site mandatory to get enough bone support to dental implants in order to perform a prosthetic rehabilitation.An original technique provides for the application of a thin layer of anorganic bovine bone granules and a collagen membrane on the top of the corticocancellous onlay bone grafts to reduce in a remarkable way the graft resorption due to remodeling.The results of a clinical prospective study and a histomorphometric analysis done on autogenous grafts harvested from the iliac crest showed that the proposed technique is able to maintain the original bone volume of the corticocancellous blocks.

ABSTRACT
Physiologic resorption due to remodeling processes affects autogenous corticocancellous grafts in the treatment of atrophic jawbone alveolar ridges. Such a situation in the past made overgrafting of the recipient site mandatory to get enough bone support to dental implants in order to perform a prosthetic rehabilitation. Anorganic bovine bone, conventionally used to treat alveolar bone deficiencies in implant surgery, showed a high osteoconductive property thanks to its micro and macrostructure very similar to that of human hydroxyapatite. An original technique provides for the application of a thin layer of anorganic bovine bone granules and a collagen membrane on the top of the corticocancellous onlay bone grafts to reduce in a remarkable way the graft resorption due to remodeling. The results of a clinical prospective study and a histomorphometric analysis done on autogenous grafts harvested from the iliac crest showed that the proposed technique is able to maintain the original bone volume of the corticocancellous blocks.

Mentions: The study was performed with 12 adults, with mean age 55 years, affected by class V or VI maxillary atrophy according to Cawood and Howell with a 2 or 3 mm of residual horizontal ridge; the bone hardness of each patients could be associated to the grade 3 – 4 according to the Misch and Judy classification [20, 21] (Figs. 1, 2).
