Fracture fixation using adhesive is a promising alternative in craniofacial surgeries, replacing the plates and screws system. The advantages include the ease of application and avoidance of drilling holes that may weaken the bone and cause fractures. In this study the bond strengths of selected adhesives were evaluated and compared with resorbable plates and screws. Four adhesives, octyl-cyanoacrylate, N-butyl-cyanoacrylate, a novel methyl-methacrylate, and a novel cyanoacrylate derivative, were tested for their microtensile and shear bond strengths. The bone samples were cut into rectangular bars and bonded with selected adhesives for microtensile testing. For the shear bond test, paired bars were bonded at the overlap, while two other sets of bars were attached by a Lactosorb plate using either adhesive or screws. Data were analysed by analysis of variance (ANOVA). The microtensile bond strengths of N-butyl-cyanoacrylate, novel cyanoacrylate derivative, and novel methyl-methacrylate derivative were significantly greater than octyl-cyanoacrylate. When bone sections were fixed with resorbable plates and adhesives, shear bond strength was significantly greater for N-butyl-cyanoacrylate than plate and screws, while the bond strengths of other adhesives were comparable with the plate and screws. N-Butyl cyanoacrylate was shown to have the greatest potential for fixation of fractured bone in craniofacial surgical applications.
