A sinus lift is a type of bone graft used by a periodontist when the top jaw isn’t quite tall enough. Sometimes a dentist will need to install dental implants, but they can’t actually get into that top jaw. Sometimes the sinuses are just too close together. In any event, a sinus lift can help correct the problem.
A sinus lift is a type of bone graft, so a bone or bone substitute will be added to the roof of the mouth. The sinuses are separated to allow the surgeon to insert a piece of donor bone, bovine bone, porcine bone, or synthetic bone substitute into the top jaw.
There are several reasons why a patient may need a sinus lift. Sometimes when teeth are lost, the bone that supports the teeth will shrink. When this happens on the top jaw, it can cause the sinuses to drift closer together. Sometimes bone can be lost due to periodontal (gum) disease. Still other cases involve a patient with a naturally small sinus.
The surgeon will make a small incision in the place your back teeth used to be, raising up the flap of skin that covers the roof of your mouth. There’s a membrane that lines the sinus, and the surgeon carefully pushes that aside. Bone graft material is then placed into the space where your sinuses used to be. Over the next six to nine months, this material will fuse with your existing bone.
The procedure may sound a bit scary, but you’ll be comfortably sedated during the procedure, and your dentist will give you thorough instructions to help prevent discomfort during the healing process. Any form of bone grafting can be complicated, so we recommend that you contact our Plantation dental office for a consultation.
