This case report documents the placement of a single implant fixture in an incisor extraction socket, with the adjacent lateral incisor developing periapical pathosis within 2 weeks. This root-end inflammatory process proceeded to communicate with the surface of the implant fixture. Although endodontic therapy was performed within one week on the devitalized tooth, and extensive osteomyelitis developed around the implant. Three weeks after placement, the fixture had to be removed. The osteotomy site appeared to be healing uneventfully during the one month follow-up period. Seven possible causes for this occurrence are discussed.
本病例报告记录了在一颗切牙拔牙窝内植入单个种植体基台的情况，相邻侧切牙在2周内出现根尖周病变。这种根尖部炎症过程蔓延至与种植体基台表面相通。尽管在这颗失活牙上于一周内进行了根管治疗，但种植体周围仍发生了广泛的骨髓炎。植入三周后，不得不取出基台。在为期一个月的随访期内，截骨部位似乎愈合良好。本文讨论了出现这种情况的七种可能原因。
