To present a rare clinical case of migration of a displaced implant fragment from the maxillary sinus to the stomach.
A 66-year-old man was referred from a local dental clinic to remove a displaced implant apical fragment in the left maxillary sinus. After 15 days from the displacement, no foreign body was seen in the maxillary sinus or in any other craniofacial cavity. Thoracic and abdominal radiographs were taken, and a 3 × 3 mm radiopaque object, which corresponded to the piece of implant fragment, was detected within the patient's stomach.
Follow-up radiographs were taken to monitor the progress after 1 week, and it was found that the radiopaque object had disappeared.
A displaced dental implant fragment in the maxillary sinus can migrate and exit from the maxillary sinus within a few days. Since it presents a potential risk for swallowing or aspiration, displaced implants or other objects in the maxillary sinus should be removed immediately. Before removal, additional radiographs are recommended to confirm the current position of the implant.
介绍一例罕见的移位种植体碎片从上颌窦迁移至胃内的临床病例。
一名66岁男性患者从当地牙科诊所转诊来取出左上颌窦内移位的种植体根尖碎片。移位15天后，在上颌窦或任何其他颅面腔内均未发现异物。拍摄了胸部和腹部X线片，在患者胃内检测到一个3×3毫米的不透射线物体，与种植体碎片相符。
1周后拍摄随访X线片以监测进展，发现不透射线物体已消失。
上颌窦内移位的牙种植体碎片可在数天内从上颌窦迁移并排出。由于其存在吞咽或误吸的潜在风险，上颌窦内移位的种植体或其他物体应立即取出。在取出之前，建议额外拍摄X线片以确认种植体的当前位置。
