Abstract

The clinical case of the 6-years old patient with constricted maxilla and transverse discrepancies between the maxilla and the mandible. The primary goal of the treatment is to lengthen and expand the dentition in order to create conditions for growth of the apical base. Aim — evaluate the effectiveness of the treatment using a fixed FitFree appliance for the rapid palatal expansion, performed using digital technologies. The patient was treated using a fixed expansion appliance that was performed by computer-aided design and manufactured by 3D-modelling and printing. Orthodontic treatment of the patients with early age maxillary deformity using fixed expanding appliance normalizes the shape and size of the dental alveolar arches, forms a stable occlusion, and creates conditions for the adaptation and proper development of the lower jaw. Using digital methods in the treatment of the transversal anomalies may provide high accuracy of the appliance manufacturing.

Key words:

maxillary deformity, cross-bite, rapid maxillary expansion, FitFree™, three-dimensional modelling, three-dimensional printing
