Abstract：
Peripheral ossifying fibroma (POF) is a benign localized lesion originating from gingival and alveolar oral mucosa. Its origin can be cells of periodontal ligament. The lesions usually develop in women in their twenties. POF is a complex clinical and histological diagnosis due to its shared characteristics with many other conditions. In this paper, we presented a case of an atypical peripheral ossifying fibroma (POF) in the left lateral part of the mandible in a 70-year-old male patient who had two semicircular bridges supported on four implants in the upper and lower jaws. A review of CBCT and orthopedic imaging showed no visible intraosseous changes. Histological analysis revealed the diagnosis of POF. The case in question is interesting, as elaborated on in the discussion section of this paper because POF is usually found in female patients aged between 20 and 30 years.
摘要：
周围骨化纤维瘤（POF）是起源于牙龈和肺泡口腔粘膜的良性局部病变。其起源能够是牙周膜细胞。病变通常在二十多岁的女性中发展。POF是一种复杂的临床和组织学诊断，因为它与许多其他疾病具有共同的特征。在本文中,我们介绍了一例70岁男性患者的下颌骨左外侧部分的非典型周围骨化性纤维瘤(POF),该患者在上颌和下颌的四个植入物上支撑有两个半圆形桥.CBCT和骨科影像学检查显示，骨内无明显变化。组织学分析显示POF的诊断。这个案子很有趣,如本文讨论部分所述，因为POF通常存在于20至30岁的女性患者中。
