Abstract: Objective To evaluate short-term clinical performance of single LAVA zirconia crowns for restoration of anterior teeth. Methods 56 cases of anterior teeth defect patients received LAVA zirconia all-ceramic single crown restorations. Clinical follow-up survey of 3 months, 6 months and 12 months after restoration were processed according to the modified USPHS criteria. Results Within 12 months, 56 patients with 85 LAVA zirconia restorations have met Bravo standard. Color matching rate of these restorations reached 97.6% of Alpha standard, and appearance, marginal fit, materials reached 97.6%, 84.7%, 95.3% respectively.
