FAQs About This New and Miraculous Procedure

How can sinus surgery contribute to the replacement of missing back teeth with dental implants?
Dental implants must be anchored the in bone to be successful. Maxillary sinus surgery can help regenerate bone that has been lost and is critically needed to anchor dental implants.

What are the maxillary air sinuses?
Inside the upper jaw, or “maxilla,” are structures known as the maxillary air sinuses, one on either side of the upper jaw. Each sinus is an air-filled space lined by a membrane. Upper back teeth are normally encased in the bone of the maxilla, below the sinuses.

Why is it important to replace missing back teeth?
Replacing back teeth restores the ability to eat, chew, and talk properly. The back teeth also provide facial and cheek support.

Why use dental implants?
Dental implants are the state-of-the-art method for replacing missing teeth.

Why does bone loss occur?
Unless special precautions are taken to prevent it, when teeth are lost, the bone supporting them is also lost.

If there is insufficient bone to anchor dental implants, what are the alternatives?
If all the back teeth are lost and dental implants cannot be placed, removable upper dentures may be the only alternative.

How do you determine whether a sinus surgical procedure is necessary?
The size, shape, and remaining bone of the maxillary sinuses influence whether you can have dental implants with or without a sinus surgical procedure.

How does surgery grow bone?
A small window is created in the sinus wall above where implants need to be placed. The sinus membrane is lifted and the space thus created filled with bone grafting and biologically active bone generating materials. The window is then closed and simply heals.

How is the surgery done?
The surgical procedures are performed from inside the mouth in the area just above the missing back teeth. They are generally carried out under local anesthesia (small shots, just like for a filling), sometimes with the addition of sedation or anti-anxiety medication.

How do bone grafts work?
Bone grafts act as scaffolds that the body replaces with its own bone. The most well researched bone substitute grafting material is currently bovine (cow) bone. All grafting materials are approved by the Food and Drug Administration. They are specially treated to render them completely sterile, non-contagious, and free of rejection factors.

What can I expect after surgery?
Moderate swelling and discomfort after surgery generally lasts for a few days to a week, about the same as having an upper impacted wisdom tooth removed. Supportive treatment usually includes a course of antibiotics to prevent infection and prescription strength medication of the aspirin or ibuprofen type. A decongestant may also be prescribed, if necessary. Healing is generally uneventful.

Who performs this surgery?
Maxillary sinus augmentations are usually carried out by oral surgeons, periodontists, or appropriately trained general dentists. Proper assessment of your situation and diagnosis are critical pre-requisites to the right procedure.
