An area of deep, long-standing recession on a mandibular first premolar was treated for root coverage in a 40-year-old woman. The recession was 6.0 mm deep with a probing depth of 2.0 mm, and there was no attached gingiva. A thick (1.5-mm) free autogenous epithelium and connective tissue graft from the palate was placed to the cementoenamel junction of the tooth after instrumentation and tetracycline conditioning of the root surface. The tooth and facial soft tissues were removed in block section 10.5 months later. At the time of extraction, there had been a gain of 5.0 mm of root coverage, and there was 5.0 mm of keratinized gingiva on the facial aspect. The probing depth was 1 mm. Histologic measurement showed 4.4 mm of new attachment and 4.0 mm of new bone growth. The coronal extent of the new attachment and new bone were in an area previously exposed by recession.
一名40岁女性下颌第一前磨牙存在一处深度较深、长期的牙龈退缩区域，接受了根面覆盖治疗。该退缩深度为6.0毫米，探诊深度为2.0毫米，且无附着龈。在对牙根表面进行器械处理和四环素预处理后，将一块取自腭部的厚（1.5毫米）游离自体上皮和结缔组织移植物置于牙齿的牙骨质牙釉质界处。10.5个月后，将牙齿及面部软组织整块切除。拔牙时，根面覆盖增加了5.0毫米，面部有5.0毫米角化龈。探诊深度为1毫米。组织学测量显示有4.4毫米的新附着和4.0毫米的新骨生长。新附着和新骨的冠方范围位于先前因牙龈退缩而暴露的区域。
