Dental brackets are widely used by the orthodontists to correct the misalignment of teeth in the mouth over a long period of time. In this study, finite element analysis of orthodontic bracket has been carried out for the observation of the stress distribution and deformation pattern in the different materials bracket (Stainless Steel, Ceramic, Titanium, Polycarbonate and Nitinol) when subjected to arch wire torsion and tipping force. The simulation results were further optimized with respect to bracket attachment surface. It was found that it is possible to know the change in result is correlated with the attachment surface of the stress and deformation due to change in diameter. The results confirmed that the finite element method has proved to be successful for proper design analysis for future development of the teeth bracket.
