FEATURES:

• Following the administration of local anesthesia, the floor of the antrum is identified using trans illumination.
• Using a Caldwell-Luc approach, the mucoperiosteal flap is raised. The flap can be retracted using the Shepherd Sinus Lift Retractor #03-110-88. The retractor handle is malleable so you can contour the handle for maximum vision and control while following the zygomatic buttress to lift the tissue with the preformed ends of the retractor.
• The lateral antral wall is osteomized 1-2mm above the antral floor using the appropriate diamond bur. The osteotomy may be any shape that gives adequate access. It is recommended that the inferior osteotomy parallel the sinus floor and carry through to the Schneiderian membrane without perforation of the membrane.
• Using the sinus lift curettes, the osteomized lateral wall of the maxilla is displaced medially into the sinus while hinging on its superior margin, to form the ceiling for the bone graft and the new floor of the sinus. The sinus septi are not altered during this procedure.
• The endosteal implant sites are prepared to the appropriate sizes using the multi-stepped cutting and dilating osteotomies. If necessary, identical size burs can be used to prepare the site. In either case, the sinus membrane must be protected during the procedure.
• After the implant sites are prepared, any additional autogenous bone is harvested. The intraoral bone is mixed with freeze-dried demineralized bone and/or HA. Always use as much autogenous bone as possible. All autogenous bone should be collected during the procedure using the ACE Autografter™. This grafting material is packed against the intact medial wall of the sinus.
• The implants are placed after the medial portion of the sinus is grafted. Bone and grafting material is then packed against the anterior and posterior maxillary walls, mounding the bone against and over the implant, which is usually up to the in fractured lateral plate.
• Once the implants are placed, the lateral portion of the surgical site is packed firmly with the bone graft using the Depth Packing Gauge #714-0243.
• The mucoperiosteal flap is then repositioned and the incisions are closed with interrupted sutures (PGA suture is recommended).
• The patient is instructed not to blow his or her nose for two weeks.
• Decongestants may be used as needed.
• All instruments and tray may be purchased separately.
