Sinus Lift

The sinus lift is a surgical procedure that is performed in order to increase the bone height in the posterior maxilla, the back part of the upper jaw. We all have maxillary sinuses, they are an empty cavity that stands on both sides of the upper jaw, above the maxillary molars and just under the cheekbone. The maxillary sinuses grown during our life. Also, after the maxillary molars are extracted some amount of bone loss occurs in that area. This two events together sometimes lead to insufficient bone height in the area of the upper molars preventing us to place dental implants to replace the missing molars. In this situation a sinus lift can be performed. First we need to numb the patient with local anesthetic. Then we create an access to the inside of the sinus. Once that access is granted we will have to elevate the thin sinus membrane that lines up the inside of the sinus. We will then insert our bone graft material and then close the gums with some stitches allowing the area to heal. In some occasions the sinus lift can be combined with dental implants. We then have to wait 6 to 9 months in order for the bone inserted inside the sinus to become completely healing. This surgical procedure typically doesn't create pain but it does create a bit of swelling for 5 to 7 days that can be reduced with medication and ice.
