Displacement of dental implants into the maxillary sinus is a rare complication. This article presents a case of displaced dental implant into maxillary sinus. Retrieval of the dental implant from left maxillary sinus was performed via endoscopic sinus surgery. This case highlighted a delayed referral of a 53-year-old male by a general dental practitioner for management of a dislodged dental implant into the left maxillary antrum. The implant was dislodged during placement of a healing abutment 4 months after implant insertion to replace missing 25. Cone beam computerized tomography revealed the displaced implant was located at the ostium of the left nose. A sudden change in sinonasal pressure when the patient took a deep breath during the procedure may have created a negative pressure and suction effect causing the implant to be dislodged and embedded at the ostium. In view of its position, a referral to an otorhinolaryngologist was made for endoscopic removal of the displaced implant. This case also highlighted the need for inter disciplinary cooperation in the management of such a complication for the best interest of the patients.
牙种植体移位至上颌窦是一种罕见的并发症。本文介绍了一例牙种植体移位至上颌窦的病例。通过鼻内镜鼻窦手术从左上颌窦取出了牙种植体。该病例凸显了一名53岁男性全科牙医转诊延迟,未能及时处理移位至左上颌窦的牙种植体。种植体植入4个月后,在安装愈合基台时发生移位,以替代缺失的25号牙。锥形束计算机断层扫描显示移位的种植体位于左侧鼻窦口。手术过程中患者深呼吸时鼻窦压力突然变化,可能产生了负压和吸力效应,导致种植体移位并嵌入鼻窦口。鉴于其位置,转诊至耳鼻喉科医生进行鼻内镜下取出移位的种植体。该病例还强调了在处理此类并发症时,为患者的最大利益进行跨学科合作的必要性。
