Most commonly, a small incision is made on the premolar or molar region to expose the jawbone. A small opening is cut into the bone, and the membrane lining the
sinus is pushed upward. The underlying space is filled with bone grafting material, either from your own body or from a other sources. Sometimes, synthetic materials
that imitate bone formation are used. After the bone is implanted, the incision is sutured and the healing process begins. After several months of healing, the bone
becomes part of the patient’s jaw and dental implants can be inserted and stabilized in the newly formed sinus bone.
If enough bone between the upper jaw ridge and the bottom of the sinus is available to sufficiently stabilize the implant, sinus augmentations and implant placement
can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the graft will have to
mature for up to several months, depending upon the type of graft material used. Once the graft has matured, the implants can be placed.
