Comparative analysis of adhesive failure of orthodontic resins: An in vitro mechanical test with the finite element method

Abstract: Objective: The purpose of this study was to validate finite element (FE) method as a reliable adhesive shear strength test method by investigating and comparing the results from in vitro mechanical tests and 3-D FE simulations. Materials and Methods: Four groups of teeth (n=15) using Transbond XT (3M Unitek, Monrovia, CA) and Enlight Ormco (Glendora, CA) with metallic and ceramic brackets (Twin-Edge and InVu, TP Orthodontics, Inc., La Porte, IN) were obtained and submitted to shear bond strength tests. Subsequently, an equivalent geometric model was subjected to FE modeling analysis. ANOVA tests indicated a statistically significant difference (P<0.05) between the shear bond strength of the two bracket types regardless of the resin, and there was no interaction between the resin and bracket type. Results: FE analysis showed the stress distribution in the adhesive layer and revealed an increased stress distribution in the ceramic brackets. These results were consistent with in vitro detachment experiments. Conclusions: This study establishes that FE sub-modeling can be used to simulate adhesive resistance.
