Abstract：
Soft tissue deficiency in a tooth extraction site in the aesthetic area is a common and challenging clinical situation. This case report demonstrates the successful treatment of extensive gingival recession and buccal bone dehiscence associated with a hopeless tooth. Initially, a connective tissue graft was used to cover the root and thicken the soft tissue. After 2 months, the tooth was extracted, an implant was immediately placed, and a temporary restoration was installed. After 3 months, the soft tissue exhibited a natural and harmonious architecture. A custom zirconia abutment and crown were then fabricated and placed. At the 4-year follow-up, the peri-implant tissue displayed satisfactory aesthetics, with a well-structured buccal bone plate and healthy peri-implant indicators. This two-stage approach, addressing gingival recession first and proceeding with immediate implant placement after soft tissue healing, proved to be a safe and effective method with stable long-term results.
摘要：
在美学区域中的拔牙部位中的软组织缺陷是常见且具有挑战性的临床情况。此病例报告证明了与无望牙齿相关的广泛牙龈退缩和颊骨开裂的成功治疗。最初，使用结缔组织移植物覆盖根部并增厚软组织。两个月后,牙齿被拔掉了,立即放置了植入物，并安装了临时修复。三个月后,软组织呈现出自然和谐的建筑。然后制造并放置定制的氧化锆基牙和牙冠。在4年的随访中，种植体周围组织显示出令人满意的美观，具有结构良好的颊骨板和健康的种植体周围指标。这种两阶段方法，首先解决牙龈衰退，并在软组织愈合后立即进行植入物放置，被证明是一种安全有效的方法，具有稳定的长期结果。
