The maxillary sinuses are behind your cheeks and above the upper back teeth. These sinuses are empty, air-filled spaces. Sometimes the roots of the upper back 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. If the sinus cavity is too close, it is impossible to place dental implants without a sinus augmentation procedure.
The quality and quantity of jaw bone is key to a successful and long-lasting dental implant. If bone loss has occurred due to injury or periodontal disease, a sinus augmentation procedure can raise the sinus floor and allow for new bone formation.
There are two types of sinus lift procedures: direct and indirect. Depending on the amount of bone remaining in this area, Dr. Garibov may recommend one over the other. Sinus lift procedures are not painful and you will be comfortably numb throughout the appointment. Some patients prefer to not be fully awake during these procedures and our office is happy to offer oral sedation for your comfort.
The Indirect Sinus Augmentation
If enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the implant well, sinus augmentations and implant placement can sometimes be performed as a single procedure! Dr. Garibov is able to lift the sinus in combination with preparing the site for implant placement.
The Direct Sinus Augmentation
If not enough bone is available, the sinus augmentation will have to be performed first, then the graft will have to mature for 6-9 months. Once the graft has matured, the implants can be placed. During this procedure the sinus is accessed where the upper teeth used to be. The sinus membrane is then lifted upward and donor bone is placed into the floor of the sinus. Keep in mind that the floor of the sinus is the roof of the upper jaw. After the healing period, the bone becomes part of your jaw and dental implants can be inserted and stabilized in this new sinus bone.
