What is a Sinus Lift?
The maxillary sinuses are empty, air-filled space located on top of the upper teeth. When these upper teeth are removed, there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place and bone grafting may be needed before dental implants can be placed.
The key to a successful and long-lasting dental implant is the quality and quantity of bone to which the implant will be attached. If bone loss has occurred due to injury or periodontal disease, a sinus
augmentation can raise the sinus floor and allow for new bone formation. A sinus lift is one of the most common bone grafting procedures for patients with bone loss in the upper jaw. This procedure seeks to grow bone in the floor of the maxillary sinus above the bony ridge of the gum line that anchors the teeth in the upper jaw. By strengthening and growing bone in this location, dental implants can be placed and secured in the new bone growth.
How is this Oral Surgery Accomplished?
In the most common sinus augmentation procedure, an incision is made on the premolar or molar region to expose the bone. 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. After the bone is implanted, the incision is sutured up and the healing process begins. After several months of healing, the bone becomes part of the patients jaw and dental implants can be inserted and stabilized in this new sinus bone.
The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option besides wearing loose dentures.
These surgeries are performed in our out-office surgical suite under IV sedation or general anesthesia. After discharge, bed rest is recommended for one day and limited physical activity for one week.
