A case of an implant periapical lesion (IPL) proceeding to acute osteomyelitis is presented, most likely due to surface contamination of the implant. Five weeks post placement of two anterior mandibular implants, symptoms of acute pain from one implant presented. This symptom and later swelling were unresponsive to antibiotics. On removal of the implant, there was a purulent discharge which, following microbial analysis, proved to be a pure growth of Staphylococcus aureus. A replacement implant was positioned in the site of the previously lost implant ten weeks later, with no recurrence of infection. Staphylococcus aureus can be isolated commonly from the mouths of denture wearers. When an IPL affects a recently placed implant its removal should be accepted but its replacement also considered.
本文报告了一例种植体根尖周病变（IPL）发展为急性骨髓炎的病例，很可能是由于种植体表面污染所致。在下颌前部植入两颗种植体五周后，其中一颗种植体出现急性疼痛症状。这种症状以及随后出现的肿胀对抗生素治疗无反应。取出种植体时，有脓性分泌物，经微生物分析，证实为金黄色葡萄球菌纯培养物。十周后，在先前丢失种植体的部位植入了一颗替代种植体，感染未复发。金黄色葡萄球菌在戴假牙者口腔中很常见。当IPL影响到最近植入的种植体时，应接受种植体的取出，但也应考虑进行替代种植。
