BACKGROUND:IPS e.max Presshas an excelent biocompati bility and corrosion resistance, which obtains satisfactory clinical outcomes on dental veneers, inlay and onlay restorations. But little is reported on molar monolithic restoration by IPS e.max Presscrown.
OBJECTIVE:To evaluate the clinical effects of IPS e.max Press crown on molar repair after root canal therapy.
METHODS:Totaly 215 patients with 324 affected molars, including 88 males and 127 females, aged 22-58 years old, were enroled for repairing with IPS e.max Presscrown. Then the color, shape, fracture and edge coloring of the restoration, marginal discrepancy, secondary caries and gingival health status were assessed after a 3-year folow-up.
RESULTS AND CONCLUSION:During the folow-up, 324 dental restorations met the class A standards for color, marginal discrepancy, shape as wel as secondary caries. In addition,3restoration swere fractured, 14 restorations had margin coloring, and 8 restorations appeared to have gingival inflammation. More than 95% restorations were scored grade A. These results indicate that IPS e.max Press crown applied to molar repair after root canal therapy can achieve ideal outcomes.
