Fibrous dysplasia (FD) is a self-limiting benign disease with slow progression in which the normal bone is replaced by dysplastic fibrous tissue. The craniofacial skeleton is one of the most commonly affected areas, and it can create unique challenges in dental implant therapy. This case aims to report an unusual presentation of FD localized in the alveolar crest bone of the edentulous site, causing special obstacles to implant placement, and provide a diagnostic and treatment process that may be referenced.
A 32-year-old female patient presented with an abnormal expansion of the alveolar crest on the edentulous site of the mandibular first molar, which caused insufficient inter-arch space and pseudo-pocket in the adjacent teeth, previous medical history of residual root that existed for many years before tooth extraction was identified retrospectively. FD was diagnosed by the clinical, radiographic, and pathological examination, and the curettage was performed to remove abnormal bone tissue and obtain adequate restorative space for further implant therapy. This intervention was followed by histologically confirmed healing and successfully integrated implant placement.
We described an unreported pathogenic site of FD that occurred at the alveolar ridge of the edentulous site, which ended up with satisfactory oral implant rehabilitation through 5-year sequential diagnosis and treatment.
骨纤维异常增殖症（FD）是一种自限性良性疾病，进展缓慢，正常骨组织被发育异常的纤维组织所取代。颅面骨骼是最常受累的部位之一，在牙种植治疗中会带来独特的挑战。本病例旨在报告一例位于无牙区牙槽嵴骨的FD罕见表现，其给种植体植入造成特殊障碍，并提供一个可供参考的诊断和治疗过程。
一名32岁女性患者，下颌第一磨牙无牙区牙槽嵴出现异常膨隆，导致牙弓间间隙不足及邻牙出现假性牙周袋，回顾性发现拔牙前存在多年的残根病史。通过临床、影像学和病理检查诊断为FD，并进行刮治以去除异常骨组织，为进一步的种植治疗获得足够的修复空间。该干预措施之后实现了组织学证实的愈合以及种植体的成功植入。
我们描述了一个未被报道的FD致病部位，其发生在无牙区牙槽嵴，通过5年的序贯诊断和治疗，最终实现了满意的口腔种植修复。
