Resumen
Patients suffering from various levels of periodontal breakdown show increased problems related to the amount of orthodontic force (usually light) needed to be safely applied to minimize ischemic, necrotic, resorptive, and further periodontal loss risks. At the bracket level, the bond failure risk is another issue that must be addressed. This study helps practitioners regarding the biomechanical stress distribution in both the stainless-steel bracket (commonly used in daily practice) and the enamel component, proving a non-homogenous stress distribution nature and a lack of influence of the periodontal breakdown process over this stress distribution. From a scientific point of view, both practitioners and researchers have a clearer image about the biomechanical behavior of the stress distribution in periodontal breakdown simulation (with this being the first study to address this issue) and are provided with a more comprehensive modality to understand the finite element analysis principles and the correct selection and use of different failure criteria.
