Background: All-ceramic crowns have become increasingly used also in the posterior regions, but there are only few studies documenting the clinical outcome of these restorations. The aim was therefore to present the 3-year outcome of zirconia single crowns. Materials & Methods: All patients treated with porcelain-veneered zirconia single crowns in prosthodontic department. The patient records were scrutinized for data on the restorations and the supporting teeth. Information was available for 152 patients and 260crowns. At the 3-year recall appointments, a sample of 22 patients with 40 crowns was clinically examined and interviewed regarding patient satisfaction. Results: Most crowns (78%) were placed on premolars and molars. The clinical outcome of crowns was favourable. No zirconia core fractured and no caries was observed on the abutment teeth.  Patient satisfaction with the zirconia crowns was in general high. Conclusions: The porcelain-veneered zirconia crowns showed good clinical results, were well accepted by the patients, and only few complications were reported over the 3-year follow-up period. Zirconia crowns can be alternative for metal –porcelein crowns in posterior teeth.
