Study on the short-term and long-term effect of IPS Empress II porcelain laminate veneer in restoration for esthetic restoration of anterior teeth

Objective To explore the short-term and long-term effect of IPS Empress II porcelain laminate veneer in restoration for esthetic restoration of anterior teeth.Methods 46 patients with 118 defective anterior teeth were divided into two groups,the treatment group(23 cases 59 teeth)and control group(23 cases 59 teeth) was given with IPS Empress II porcelain laminate veneer and conditional Co-Cr alloy handcuffed ceramic crowns,respectively.All the cases were asked for a second visit in 1 week after restoration,and the integrity of ceramic veneer,marginal adaptation,gingival health,post-operative sensitivity and color match were evaluated during 3-year follow-up.Results The degree of satisfaction on the color,shape and adaptation in treatment group were all higher than those in control group(P 0.05).After restoration for 6 month,the marginal adaptation,post-operative sensitivity and color match in treatment group were all better than those in control group(P0.05).There was also significant difference on the marginal adaptation and gingival health between the two groups(P0.05).Conclusion IPS Empress Ⅱ porcelain laminate veneer can save the body organization at the extreme,and it has the advantage of aesthetics and biological characteristics,so it can be used as an ideal restoration method for esthetic restoration of anterior teeth.
