Sinus augmentation, when performed with simultaneous or delayed implant placement, is a predictable procedure in augmenting deficient ridges. Traditionally, sinus augmentation was performed with either the lateral window or crestal osteotome approaches. In this case series, a new sinus floor elevation technique is proposed to treat specific cases of extremely atrophic maxillae. Case Series: In this technique, a window is opened from the ridge crest instead of the lateral wall. Particulate bone graft is subsequently packed through the crestal window to elevate the Schneiderian membrane. Primary closure is achieved and implant placement is performed after healing is completed. Conclusion: This new crestal sinus elevation technique combines direct visualization of the Schneiderian membrane with minimal flap reflection in the augmentation of severely atrophic maxillae in preparation for subsequent implant placement.
