Methods Anterior subgingival roots were treated with root canal treatment and surgical crown lengthening before restoring with post-core crowns. A three-year follow-up was conducted to evaluate the clinical effects. Results A total of 34 teeth from 24 patients were enrolled in this study. Within 3-year follow-up period, one case of root fracture and one case of crown finishing line exposure were found. The clinical effects were functionally and esthetically satisfied in the other 32 teeth. Conclusion Post-core crown following surgical crown lengthening can effectively restore subgingival residual roots.
