摘　　要：对1例畸形根面沟引起的重度牙周和根尖周病变患者,先将患牙作完善的根管充填,然后在腭侧翻瓣,清创处理,直视下将裂沟冠向1/2备洞,3M玻璃离子黏固粉永久充填,最后用不可吸收性聚四氟乙烯膜(e-PTFE)覆盖全部骨缺损区,缝合。4周后将该膜去除。经3a随访观察,牙龈未发生红肿、溢脓等症状,叩诊(-),牙不松动,X线片示根周及根尖区有明显的新生牙槽骨形成。This paper reported one case with severe periodontal lesions caused by malformed lingual groove treated by guided tissue regeneration. The periodontal lesion was exposed palatally after the tooth had been treated with root canal therapy, the alveolar bone and the root surface was prepared, an unabsorbable member of e-PTFE was placed into the wound,and removed after 4 weeks, the patient was followed up for 3 years. The lesion recovered well three years after the operation, all of the periodontal tissue was in a healthy condition. It is advisable that guided periodontal tissue regeneration can be used as a new method to treat periodontal destruction induced by malformed lingual groove.
