Sinus Augmentation, North Dallas TX

What is a Sinus?

The maxillary sinuses are behind your cheeks and on top of the upper teeth. These sinuses are empty, air-filled spaces. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. 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. When the sinus wall is very thin, there may not be adequate bone volume to place an implant.

The Sinus Augmentation Procedure

The key to a successful and long-lasting dental implant is the quality and quantity of jawbone to which the implant will be attached. If bone loss has occurred in or around the sinus, a sinus augmentation procedure can raise the sinus floor and allow for new bone formation.

In the most common sinus augmentation procedure, the sinus is elevated at the time of implant placement preventing the necessity for two separate surgeries. The membrane lining the sinus is pushed upward through the same hole that the implant will be placed. The underlying space is filled with bone grafting material. After the bone is implanted, the dental implant will be placed and the healing process begins. After several months of healing, the implant can be restored.

If there is minimal to no bone in the sinus, the bone graft will need to be performed first.  In this procedure, the bone will need to heal for approximately six months prior to implant placement. 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.
