Endodontic microsurgery is a predictable treatment option when orthograde treatment or retreatment is unsuccessful or unfeasible. However, when there is a gross compromise of periapical bone, achievement of bone regeneration after the surgical procedure may be hampered. In such cases, the application of guided tissue regeneration principles, with adjunctive use of leukocyte platelet-rich fibrin to fill the bone defect as a bone substitute and as a membrane to cover the site, provides a cost-effective solution with the benefits of accelerated physiological healing and reduced post-surgical pain and discomfort. This case report presents 2 cases of endodontic microsurgery of the upper lateral incisors with loss of buccal cortical plate, where platelet-rich fibrin was successfully applied.
当常规治疗或再治疗不成功或不可行时，牙髓显微外科手术是一种可预测的治疗选择。然而，当根尖周骨严重受损时，手术过程后骨再生的实现可能会受到阻碍。在这种情况下，应用引导组织再生原则，辅助使用富含白细胞血小板纤维蛋白填充骨缺损作为骨替代物并作为覆盖该部位的膜，提供了一种经济有效的解决方案，具有加速生理愈合以及减轻术后疼痛和不适的益处。本病例报告展示了2例上颌侧切牙牙髓显微外科手术病例，这些病例存在颊侧皮质骨板缺失，其中成功应用了富含血小板纤维蛋白。
