Clinical observation of onlay combined with immediate dentin sealing technique to repair moderate to severe molar defects

Objective:To evaluate the clinical effect of onlay combined with immediate dentin sealing technique in repairing moderate to severe molar defects.Methods:141 molars with 1 to 3 axial-wall defects in 126 patients were selected in our department from January 2017 to October 2018.The molar defects were repaired with CAD/CAM onlays after root canal treatment and immediate dentin sealing(IDS).6,12 and 24 months after surgery,patients were asked for re-examination and clinical curative effects evaluation were performed.Results:A total of 130 molar onlays in 118 patients completed a 24-month follow-up,which performed well in terms of tooth integrity,onlay retention,edge adhesion,adjacency,and gingival conditions.Only 5 cases failed:2 cases of food impaction,2 cases of onlay shedding,1 case of gingivitis.Conclusion:Onlay combined with immediate dentin sealing technology has a stable effect in repairing moderate to severe molar defects,which can be used as one of the clinical restoration options.
