Subgingival crown fractures with pulp exposure in permanent teeth present both endodontic and restorative problems with unfavorable prognosis. Numerous restorative techniques such as resin composite restorations with and without pins, crowns and reattachment of the fractured dental fragment could be listed as the treatment options. There are several successful cases in the literature where advantages of less microleakage and proper gingival biocompatibility in cases with reattachment of the tooth fragment were reported. Two cases of palatinal subgingival crown fractures are reported. Both had been restored by reattachment of the fragment and composite with the help of the flap surgery. Follow up visits (Case 1 for 4 years and Case 2 for 1 year) revealed satisfactory esthetics and function.
恒牙中伴有牙髓暴露的龈下冠折同时存在牙髓病和修复问题，预后不佳。诸多修复技术，如带或不带桩的树脂复合材料修复、冠修复以及折断牙碎片的重新附着等，都可列为治疗选择。文献中有几例成功病例，报道了牙碎片重新附着病例中微渗漏较少以及牙龈生物相容性良好的优点。本文报告两例腭侧龈下冠折病例。两例均通过瓣手术辅助下的碎片重新附着和复合材料修复。随访（病例1随访4年，病例2随访1年）显示美观和功能均令人满意。
