When Bone is inadequate for dental implant placement in the upper back teeth bone is added to the sinus so implants may be placed. Implants can be placed at the same time the bone is added if the implants can be stabilized, if not the implants will be placed after the bone graft heals for 6-9 months.
The sinus is a hollow area in the upper jaw which one of the most predicable sites for the addition of new bone. Access is made inside the mouth. The sinus membrane is paper thin and is lifted. A collagen membrane is placed under the sinus membrane and it will act as the floor of the new sinus cavity. A combination of autogenous, allograft and alloplastic bone products are used to build new bone in the sinus. PRP and fibrin are sometimes used to promote healing.
Please refer to the bone grafting area under "Surgery Information" to learn more about the bone products.
The surgical site is closed using a synthetic collagen or donor membrane and the gum tissue is sutured over the site and allowed to heal for 6-9 months.
Sinus grafting historically is a very predictable area to add bone.
