| Objective:The aim of this study was to evaluate the clinical effect of IPS e. max Press ceramic endocrown restoring posterior teeth after root canal therapy.Methods:Twenty-six posterior teeth after root canal therapy were restored by endodontic graduate students in Wuhan University Stomatological Hospital with IPS e. max Press ceramic endocrown. The patients were recalled 18-24 months after the restoration and the restorations were assessed by using the modified USPHS criteria including secondary caries, gingivitis, tooth fracture, marginal discoloration, marginal integrity criteria, restoration fracture/debond.Results:Of all the 26 teeth, one restoration was found broken. Two restorations had slight damage of marginal integrity and one had slight damage of occlusal surface. Other defects of endocrowns, or tooth and gingiva problems caused by the restorations were not found.Conclusion:Endocrown is an effective method of restoring posterior tooth after root canal therapy. |
