Abstract:
BACKGROUND:IPS e. max Press porcelain crown has been widely used in clinical restoration because of its aesthetic effect and biological properties. OBJECTIVE:To explore the effect of IPS e. max Press porcelain crown in esthetic restoration of anterior teeth in terms of marginal adaptation and color match. METHODS:Total y 52 patients with 138 defective anterior teeth (20 males and 32 females, 18-45 years old, including 62 anterior tooth defects, 46 tooth traumas, 30 denticles) were divided into two groups randomly:treatment group (26 cases) and control group (26 cases) were given IPS e.max Press porcelain crown and conditional Co-Cr al oy handcuffed ceramic crowns, respectively. Al the cases were asked for a second visit in 1 week after restoration, and the integrity of ceramic veneer, marginal adaptation, gingival health and color match were evaluated during 6-month and 2-year fol ow-ups. RESULTS AND CONCLUSION:The degrees of satisfaction on the color, shape and adaptation in the treatment group were al higher than those in the control group (P<0.05). At 6 months after restoration, the marginal adaptation, gingival health and color match in the treatment group were al better than those in the control group (P<0.05). At 2 years after restoration, there was also a significant difference in the marginal adaptation, gingival health and color match between the two groups (P<0.05). IPS e.max Press porcelain crown has the advantages of aesthetics and biological characteristics, so it can be used as an ideal restoration method for esthetic restoration of anterior teeth.
