Methods: 23 patients(26 teeth) which had crown fracture more than 3 mm under the gingival were enrolled in this study.After those residual roots and crowns were endodontically treated following the conventional root canal therapy,the casting post-core and the porcelain fused mental crowns with wings were applied to reconstructing those missing crowns. Results: After 3 months to 5 years clinic observation,restored crowns were still stable with good retention and fracture resistance. Conclusion: Those residual roots and crowns can be preserved by this innovative way and can also acquire satisfactory effects in esthetics and functions.
