目的:观察牙体组织大面积缺损至龈下2mm的磨牙,经桩核冠修复后的临床效果。方法:对94例97个冠部缺损至龈下的磨牙行牙冠延长术,重建牙龈上皮附着,再行桩核制作及全冠修复。结果:在修复后三年多时间内,仅1个磨牙因根折而修复失败,其余病例均达到了良好的修复效果。结论:冠部大面积缺损至龈下的磨牙应用牙冠延长术后行桩核冠修复治疗,可恢复患牙的咀嚼功能,取得较好的远期效果
OBJECTIVE: To observe the clinical effect of large area defect of tooth tissue to 2mm subgingival molars restored by post-core crown. Methods: Ninety-nine cases of coronavirus from the crown to the subgingival molars were performed crown extension, reconstruction of the gingival epithelium, reconstruction of the post-core and crown restoration. Results: Within a period of more than three years after repair, only one molars failed to repair due to the root fracture, and the remaining cases achieved a good repair effect. CONCLUSIONS: A large area of the crown to the subgingival molars can be repaired with the crown extended after the crown extension, which can restore the chewing function of the affected teeth and achieve better long-term results
