title: Screw fixation is superior to N-butyl-2-cyanoacrylate in onlay grafting procedure: a histomorphologic study.
abstract: The aim of this study is the histopathological evaluation of the efficiency of N-2-butyl cyanoacrylate in the fixation of bone block grafts on mandible. Autogenous monocortical block grafts taken from tibial bone were fixed to the outer surface of the angle of the mandible with N-2-butyl cyanoacrylate on the right side and mini screws on the left side. Postoperatively in the first and third months, six rabbits were killed and tissue samples were obtained from the grafted area. No significant difference was found between the cyanoacrylate and screw group with respect to inflammation or foreign body reaction. The level of graft necrosis was found to be significantly higher in the cyanoacrylate group than in the screw group in both the first and third month samples. Bone formation between the graft and recipient bone was evaluated and bone formation was found to be significantly higher in the screw group than in the cyanoacrylate group. No trabecular bone formation was observed between the graft and recipient bone in the cyanoacrylate group. Screw fixation was found to be superior to N-2-butyl cyanoacrylate in all parameters.
