Abstract: Abstract: Objective evaluation of lateral incisor lingual dislocation lines zirconia all-ceramic restorations long-term efficacy and aesthetic effect. Methods selected 106 cases from April 2012 to May 2014 in our hospital dentistry treatment of (130) lateral incisor lingual errors were randomly divided into experimental group and control group, the experimental group 53 cases (68) take zirconia all-ceramic restorations, the control group 53 cases (62) take the nickel-chromium alloy porcelain repair, follow-up of 2 years, two groups of patients to evaluate the effect of the restoration of the two groups of patients for aesthetic effect repair satisfaction to investigate the situation. Result at 2 years, the experimental group patients prosthesis shape, color matching, gums and tooth sensitivity adaptability pass rates were 97.1% and 100.0%, 94.1% and 94.1%, were higher in patients, the differences were statistically significance (P <0.05); experimental group patients satisfaction aesthetic effect prosthesis was 98.1%, significantly higher than 81.1%, the difference was statistically significant (P <0.05). Conclusion Zirconia applied lateral incisor lingual dislocation repair can effectively improve the long-term efficacy and aesthetic effects in patients, improve patient satisfaction with aesthetic effect.
