INVITED LECTURE: Optimized orthodontic mechanics based on finite element analyses.

Fixed appliances have become an integral part of contemporary orthodontic treatment, as they enable full control of tooth movement in all dimensions. However, the tooth’s response to the applied force system is not always easy to predict, due to the complexity of the applied system and the inclusion of multiple tissues and materials with differing physical propertied (tooth, periodontal attachment tissues, and orthodontic appliances). In this endeavor, the numerical simulation analyses, and specifically the finite element method, can prove of assistance to the orthodontist, as they provide a refined prediction of the resulting tooth displacement. Therefore, finite element analyses can be applied in various clinical scenarios using anatomically correct models to indicate which treatment mechanic would be most efficient in producing the desired results. Aim of the present study is to provide practically-relevant examples from the orthodontic daily routine, like tooth extrusion, applied torque to anterior teeth or uprighting of impacted second molars, where the results of the mechanotherapy can be optimized based on the results of finite element studies.
