Ten patients who underwent sinus lift surgery with simultaneous implant placement using the intrasinusal locking technique were evaluated retrospectively. All patients were scheduled for sinus floor elevation procedures with simultaneous implant placement. Schneiderian membrane perforation occurred during the lifting procedure, and conventional methods failed to repair the perforation. Therefore, an autogenous bone ring was placed at the base of the maxillary sinus and was locked to the alveolar crest with a dental implant. Marginal resorption around the dental implants was measured on panoramic radiographs. Prosthetic rehabilitation was performed at 6 months postoperative. The overall survival rate of the implants over a mean follow-up of 24.3 months was 90%. One case failed due to resorption of the alveolar crest around the implant as a result of infection; the implant and the adjacent ring were removed at 1 month postoperative. At the time of writing, the nine implants placed using the documented technique continue to function well, without any signs of peri-implant disease. The proposed approach allows for simultaneous dental implant placement in the extremely atrophic maxilla, even if there is extensive perforation of the Schneiderian membrane.
对10例采用鼻窦内锁定技术同期植入种植体进行鼻窦提升手术的患者进行了回顾性评估。所有患者均计划进行同期植入种植体的鼻窦底提升手术。在提升手术过程中发生了上颌窦黏膜穿孔，传统方法未能修复穿孔。因此，将自体骨环置于上颌窦底部，并用牙种植体将其锁定于牙槽嵴。通过全景X线片测量种植体周围的边缘骨吸收情况。术后6个月进行修复治疗。在平均24.3个月的随访期内，种植体的总体生存率为90%。1例因种植体周围牙槽嵴感染吸收而失败，术后1个月取出种植体及相邻骨环。在撰写本文时，采用所述技术植入的9枚种植体仍功能良好，无任何种植体周围疾病迹象。即使存在上颌窦黏膜广泛穿孔，所提出的方法也允许在极度萎缩的上颌骨中同期植入牙种植体。
