Sažetak
Complicated crown fractures involve enamel, dentine and the pulp, whereby the most commonly affected tooth is the maxillary central incisor. Various treatment modalities are available depending upon the clinical and radiographic status. In this case a multidisciplinary treatment of complicated crown fractures of both maxillary central incisors in a 12-year-old boy is presented. Proper root canal treament was carried out. The patient and his parents wished for an esthetic, metal-free restoration of the lost tooth structure. The main part of the left incisor was perserved, but the crack on the right incisor extended about 3 mm subgingivally. Therefore, in the first phase the right central incisor was extruded using rapid orthodontic extrusion until all tooth margins layed supragingivally. The tooth was splinted for 2 months as a retention phase. Afterwards perodontal plastic surgery was performed to correct the discrepancy of the gingival margin which occured as a consequence of forced eruption. FRC Postec Plus posts (Ivoclar Vivadent) were used to stabilize the restorations and a provisional crown was placed to stabilize the soft tissue. After 2 months the teeth were definitely restored. The left incisor was built up directly using composite material (IPS Empress Direct, Ivoclar Vivadent), while the right, extruded incisor was built up with a core material followed by the placement of an all-ceramic crown (IPS Empress II, Ivoclar Vivadent). After orthodontic extrusion and the surgical recontouring of the altered gingival margin the precondition for an esthetic rehabilitation was created. By applying two different restoration methods – the direct with a composite material, and the indirect using an all-ceramic crown – an esthetic outcome was achieved. Rapid orthodontic extrusion as a simple, safe, and fast technique to reestablish biological width. It is possible to combine direct and indirect restoration modalities to achieve pleasant results.
