Rehabilitacja narządu żucia w przypadku wrodzonej obustronnej agenezy kłów stałych – opis przypadku

Abstract

Bilateral agenesis of the permanent maxillary canines in healthy individuals is extremely rare. This paper presents the case of a Polish patient diagnosed with congenital bilateral agenesis of the permanent maxillary canines as well as occlusal abnormalities in the form of left-side crossbite. To restore proper aesthetics and function, interdisciplinary therapeutic treatment was implemented. In the case presented in this paper, the aim of oral rehabilitation was to restore a functional balance by obtaining proper skeletal relationships, create optimal occlusal conditions and obtain arch continuity. After a course of orthodontic treatment involving fixed appliances on both dental arches, implantation was performed in positions 13 and 23, followed by prosthetic reconstruction. A comparative analysis of lateral cephalometric radiographs taken before the orthodontic treatment and after the completion of the combined orthodontic and implant-prosthetic treatment showed stable skeletal relationships. The values of the skeletal angles did not change, whereas the value of angle H, which describes the position of the upper lip in relation to Ricketts’ e-line, increased from 1.4° to 2.8°, which reflects an improvement in facial profile aesthetics. In the case of maxillary canine agenesis accompanied by malocclusion, interdisciplinary treatment is recommended in order to achieve optimum aesthetic and functional results.
