Displacement of dental implants into the maxillary sinus is rare, but it primarily occurs in patients with severe pneumatization of the maxillary sinus and/or deficiency of the alveolar process. Some complications such as the infection of the paranasal sinuses and formation of the oroantral fistula can be followed by the displacement of a dental implant. Therefore, the displaced implant has to be removed immediately with surgical intervention show and another plan for rehabilitation should be considered.
The conventional procedure for the removal of a displaced implant from the maxillary sinus involves sinus bone grafting and new implant placement performed in two or more steps with a significant time gap in between. Simplification of these surgical procedures can decrease the treatment duration and patient discomfort.
In this review, we discuss the anatomical characteristics of the maxillary sinus and the complications associated with implant displacement into the sinus.
牙种植体移位至上颌窦的情况较为罕见，但主要发生在上颌窦严重气化和/或牙槽突不足的患者中。牙种植体移位后可能会引发一些并发症，如鼻窦感染和口鼻瘘形成。因此，移位的种植体必须通过手术干预立即取出，并应考虑其他修复方案。
从上颌窦取出移位种植体的传统方法包括分两步或更多步进行鼻窦骨移植和新种植体植入，且两者之间有较长的时间间隔。简化这些手术程序可以缩短治疗时间并减轻患者的不适。
在本综述中，我们讨论了上颌窦的解剖特征以及种植体移位至鼻窦相关的并发症。
