Abstract

Abstract:

BACKGROUND: IPS e.max Press has an excellent biocompatibility 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 Press crown.

OBJECTIVE: To evaluate the clinical effects of IPS e.max Press crown on molar repair after root canal therapy.

METHODS: Totally 215 patients with 324 affected molars, including 88 males and 127 females, aged 22-58 years old, were enrolled for repairing with IPS e.max Press crown. 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 follow-up.

RESULTS AND CONCLUSION: During the follow-up, 324 dental restorations met the class A standards for color, marginal discrepancy, shape as well as secondary caries. In addition, 3 restorations were 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.
