BACKGROUND
Rehabilitation of edentulous jaws with dental implants has become a usual practice around the world. A very low incidence of complications is associated with this therapy. One of them is migration of dental implants into maxillary sinus. Foreign bodies inside maxillary sinus should be removed because they can cause sinusitis, but if any symptoms are present, preservation alone can be indicated. Implant removal and bone reconstruction on the same procedure reduce treatment time and allow rehabilitation with implant-supported prosthesis.
METHODS
In the present study, we report two cases of dental implants displaced into maxillary sinus that receive different treatment.
RESULTS
In one of them, implant removal and sinus lift were carried out on same procedure while on the other preservation alone was advocated.
CONCLUSION
Both treatment modalities treatments allowed installation of implant-supported prosthesis.
背景
采用牙种植体修复无牙颌在世界各地已成为一种常见的治疗方法。该治疗相关并发症的发生率非常低。其中一种并发症是牙种植体移入上颌窦。上颌窦内的异物应予以清除，因为它们可能导致鼻窦炎，但如果没有任何症状，则可仅采取保留措施。在同一手术中进行种植体取出和骨重建可缩短治疗时间，并允许使用种植体支持的假体进行修复。
方法
在本研究中，我们报告了两例牙种植体移位至上颌窦的病例，并对其采取了不同的治疗方法。
结果
其中一例在同一手术中进行了种植体取出和上颌窦提升，而另一例则仅主张保留。
结论
两种治疗方式均允许安装种植体支持的假体。
