Primjena visoko translucentnog cirkonij-oksida u estetskoj zoni- prikaz slučaja

Introduction Modern restorative materials should enable the clinician to meet the patients' high esthetic expectations, as well as requirements regarding function and durability. Diagnostics A 56-year old female presented with a vertical root fracture of the upper left incisor. Radiographic examination demonstrated a buccal bone deficiency due to the chronical inflamatory process. The occlusion was stable with sufficient interocclusal space. Therapy The patient refused implant therapy, so the preffered treatment option was an all ceramic bridge due to high esthetic demands. The material of choice was translucent Zirconia. After the atraumatic tooth extraction of tooth 21, the socket was augmented to produce an appropriate buccal bone contour. The abutment teeth 12, 11, 22 were prepared with the margins placed slightly subgingivally to ensure a highly esthetic outcome. After a temporization period of two months with a chairside provisional, the impressions were taken. In order to fabricate a functional final restoration, the patient's individual data were transferred into the CAD software using a facebow. The bridge was designed in the Ceramill Mind® software. The Zirconia core structure was milled out of a Zolid block Preshade 1 in the Ceramill Motion 2, 5-axis milling unit, sintered and then layered with IPS e.max Ceram. The try-in was carried out without any problems ; additional adjustments were not required. The restoration was luted with RelyX Unicem. Conclusion Translucent Zirconia with a state-of-the-art dental technique can provide high strength restorations with excellent esthetics and fit for the anterior zone.
