In this article the Authors show a safe and predictable technique to remove displaced implants from the maxillary sinus.
A 49-year-old female was referred, to this centre by a general dentist, for the retrieval of the ectopic dental implant. After a preliminary clinical and radiological evaluation of the case the surgical procedure was performed. A loco-regional anesthesia was carried out and then the Maxillary Sinus Retrieval Device (MSRD), proposed in this study, was inserted in the canine fossa, via a circular antrostomy 5,5mm wide, previous execution of a mucoperiosteal flap. The MSRD is a trocar, modified with a funnel-shaped cannula in order to allow the easy access of both an endoscope and a suction cannula or, in alternative, a straight forceps. The implant was easily found end retrieved thanks to the endoscopic control. The postoperative was uneventful and no nasal bleeding was reported by the patient.
The Authors recommend the use of the MSRD in order to minimize the biological sacrifice consequent to the implant retrieval in the maxillary sinus.
在本文中，作者展示了一种安全且可预测的技术，用于从上颌窦取出移位的种植体。
一名49岁女性由普通牙医转诊至本中心，以取出异位牙种植体。对该病例进行初步临床和放射学评估后，实施了手术。进行了局部区域麻醉，然后通过先前制作的5.5毫米宽的圆形上颌窦开窗术，在犬齿窝处插入本研究中提出的上颌窦取出装置（MSRD），并制作了粘骨膜瓣。MSRD是一种套管针，经漏斗形套管改装，以便于内窥镜和吸引套管或直钳轻松进入。借助内窥镜控制，很容易找到并取出种植体。术后情况平稳，患者未报告鼻出血。
作者建议使用MSRD，以尽量减少上颌窦种植体取出导致的组织损伤。
