Dental implant treatment has been applied widely in recent years. However, several complications sometimes have been reported. Although displacement of dental implants into the maxillary sinus commonly occurs during surgery, the migration of dental implants after a period of function, especially several years after dental implant placement, is very rare.
We report here removal of migrated dental implants from the maxillary sinus 4 years and 10 months after dental implant placement.
近年来，牙种植治疗已得到广泛应用。然而，有时会有一些并发症的报道。虽然牙种植体在上颌窦内移位在手术过程中较为常见，但种植体在行使功能一段时间后，尤其是在种植体植入数年之后发生迁移的情况非常罕见。
在此我们报告一例在牙种植体植入4年零10个月后，将移位至上颌窦的种植体取出的病例。
