Biomechanical Analysis of Orthodontic Appliances Through 3D Computer Aided Engineering

摘要

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, first of all the classic fixed wire appliance. In the last decades, however, 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, lingual brackets, which are less visible than vestibular brackets and clear removable aligners, made of transparent thermoplastic material and then almost invisible, raised a growing interest.
