The accidental displacement of dental implants into the maxillary sinus is an infrequent but possible complication in dental clinical practice. The main cause of implant displacement is the inadequate bone height in the posterior maxilla. This event usually occurs during surgery, and it is more rarely reported in the post-operative period, especially with long-term follow-ups.
Here, a case of an implant migrated inside the maxillary sinus at the time of abutment connection and removed 7 years later is described.
Postoperative recovery was uneventful. To the author's best knowledge, this case represents the first report concerning migration of an oral implant into the maxillary sinus removed after 7 years.
牙种植体意外移位至上颌窦是牙科临床实践中一种罕见但可能发生的并发症。种植体移位的主要原因是上颌后部骨高度不足。该事件通常发生在手术过程中，术后尤其是长期随访中较少报道。
本文描述了一例在基台连接时种植体移位至上颌窦内并于7年后取出的病例。
术后恢复顺利。据作者所知，该病例是关于口腔种植体移位至上颌窦7年后取出的首例报道。
