The aim of this study was to evaluate the effects of exposing dental implants to the maxillary sinus cavity. This is a retrospective study. Thirteen patients with 18 implants that had radiographic evidence of implant exposure to the maxillary sinuses participated in this study. We evaluated the patient's radiographs immediately after implant insertion and 12 months after operation with the patient's clinical signs and symptoms due to sinusitis. Thirteen patients with 18 implants in the maxillary sinus had no signs and symptoms of sinusitis. Radiography showed thickening of the sinus membranes in 2 patients. All penetrated implants were successfully integrated, and there were no radiographic signs of bone loss or other complications.The exposure of implants to the maxillary sinuses caused no problems in the maxillary sinuses, and bone formation occurred in THE maxillary floor when penetration of maxillary sinuses occurred without tearing of the membrane.
本研究的目的是评估将牙种植体暴露于上颌窦腔的影响。这是一项回顾性研究。13例患者的18颗种植体有影像学证据显示种植体暴露于上颌窦，参与了本研究。我们在种植体植入后立即以及术后12个月评估了患者的X光片，并结合患者因鼻窦炎出现的临床体征和症状进行分析。13例上颌窦内有18颗种植体的患者没有鼻窦炎的体征和症状。X光片显示2例患者的鼻窦黏膜增厚。所有穿透性种植体均成功整合，没有骨质流失或其他并发症的影像学迹象。种植体暴露于上颌窦并未给上颌窦带来问题，当上颌窦发生穿透且黏膜未撕裂时，上颌窦底出现了骨形成。
