Biomechanical Analysis of Orthodontic Appliances Through 3D Computer Aided Engineering

Roberto Savignano


In the field of dental health care, misaligned teeth can cause aesthetic and functional problems for the patients. Different appliances have been developed to correct malocclusions. In the last decades research in the orthodontic field has focused not only on the effectiveness of the appliances on correcting teeth position, but also on the fulfilment of comfort issues during the treatment. For this reason, many new orthodontic appliances have been developed with the aim at being minimally invasive for the patients. In particular clear removable aligners, made of transparent thermoplastic material and then almost invisible, raised a growing interest. Treatments based on clear aligners are composed of a set of thermoformed templates, having different shapes, which are sequentially worn by the patient. Each aligner is shaped a bit different than the real teeth position in the mouth in order to force teeth to move in the correct position. Even if orthodontic treatments based on the use of clear aligners are commonly used in clinical practice there is no technical literature describing how the loads are transferred from the aligner to the teeth. Since both design and production processes involves many clinical and technological skills, the optimisation of aligners features represents one of the most challenging aspects of this kind of orthodontic treatments. In this context, the present research project is focused on the development of a Finite Element Method (FEM) model to be used in the optimisation process of both geometrical and structural attributes of removable aligners.
