Pneumatization of the sinus is a common occurrence after extraction of maxillary posterior teeth. Implant procedures require a clinically acceptable level of bone to be present for implants to be placed in function. Residual bone with >4 mm of height can be managed using the indirect sinus lift procedure, whereas bone height <4 mm requires a direct sinus lift using lateral window approach. This clinical case report describes the use of autogenous core used to lift the membrane in conjunction with calcium phosphosilicate putty using minimal armamentarium, thereby avoiding the associated morbidity and complications associated with a direct sinus lift procedure.
上颌后牙拔除后窦腔气化是常见现象。种植手术需要有临床上可接受的骨水平才能植入种植体发挥功能。骨高度大于4mm的剩余骨可采用间接窦底提升术处理，而骨高度小于4mm则需要采用外侧开窗法进行直接窦底提升。本临床病例报告描述了使用自体骨核结合磷酸钙硅糊剂提升窦膜，使用的器械最少，从而避免了直接窦底提升术相关的发病率和并发症。
