Within a diatoric implant rehabilitation of the upper arch, a bone volume augmentation by means of a great sinus lift is planned. The maxillary bone is exposed by means of a crestal incision and a mesial release incision. The vestibular maxillary osteotomy is performed with a piezosurgery technique in order to preserve the integrity of the Schneiderian membrane. After removing the vestibular maxillary cortical plate, this is preserved in PRGF. The elevation of the sinus membrane allows the placement of the bovine bone graft blended with PRGF. The maxillary cortical plate is then repositioned. The crestal bone volume is augmented also horizontally, by placing a block of heterologous bone thickened with PRGF. Everything is then covered with PRGF membranes. Both mattress sutures and simple single sutures are used. Finally it is possible to appreciate the soft tissue healing at 9 months after surgery. The surgical reentry for implant placement allows us to appreciate the bone volume augmentation and the perfect healing of the maxillary cortical plate.
