           Article history:                 Objectives: To evaluate the shear bond strength and the adhesive remnant index (ARI) of
           Received 28 November 2016        different orthodontic accessories used for applying traction on impacted teeth.
           Accepted 29 September 2017       Methods: 120 bovine incisors were used. Initially, all teeth were submitted to prophylaxis,
           Available online 20 December 2017  subsequent etching with 37% phosphoric acid, application of adhesive and light polymeri-
                                            zation. Afterwards, these teeth were randomly divided into eight groups: (1) composite lingual

           Bond strength                    (5) brackets; (6) convex lingual button; (7) concave lingual button; and (8) orthodontic mesh.
           Impacted                         The groups were submitted to shear tests in a universal test machine, and ARI evaluation.
           Orthodontic appliance            Results: The group of orthodontic mesh (8) presented the best shear bond strength results
           Tooth                            with statistically significant differences comparing with the composite lingual button
                                            (p<0.001), hooks for application of traction on impacted teeth (p=0.002), hooks with chain
                                            (p=0.001), cleat (p=0.011), brackets (p< 0.001), convex lingual button (p=0.003) and convex
                                            lingual button (p<0.001). The highest mean ARI values were also obtained for the mesh group,
                                            with statistically significant differences comparing with the composite lingual button
                                            (p=0.008), cleat (p=0.004), brackets (p=0.001), convex lingual button (p=0.017) and concave
                                            lingual button (p=0.005).
                                            Conclusion: The greatest adhesion forces were obtained with the orthodontic mesh, which
                                            was statistically different from all other groups, and the lowest adhesion forces with the
                                            composite lingual button. (Rev Port Estomatol Med Dent Cir Maxilofac. 2017;58(4):219-224)
