Sinus Grafting is used when the patient’s bone is inadequate for dental implant placement in the upper back teeth. Bone can be added to allow dental implant placement using a special type of bone graft. Implants can be placed at the same time the bone is added if the dental implants can be stabilized, if not they will be placed after allowing the bone graft to heal 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, allowing a collagen membrane to be placed underneath to 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 this case. PRP and fibrin are sometimes used to promote healing.
Please refer to the bone grafting 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.
