The maxillary sinuses are behind your cheeks and on the top of the upper teeth. Sinuses are like empty rooms that have nothing in them. Some of the roots of the natural upper teeth extend up in to the maxillary sinuses. When the 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 thin, it is impossible to place dental implants in this bone.
|
|
There is a solution: Its called sinus graft or sinus lift. The specialist or skilled implantologist enters the sinus from where upper teeth used to be. The thin paper like sinus membrane is carefully lifted upward and donor bone is inserted into the floor of the sinus (Which is the roof of the upper jaw). After several months of healing, the bone becomes the part of the patient’s jaw and dental implant can be inserted and stabilized in this new sinus bone.

|
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. If not enough bone is available sinus augmentation will have to be performed first, then the graft will have to mature for several months, depending upon the type of graft material used. Once the graft material has matured, the implant can be placed.

| NERVE - REPOSITIONING |
|
The inferior alveolar nerve, which gives feeling to the lower lip and chin, may need to be moved in order to make room for placement of dental implants to the lower jaw. This procedure is limited to the lower jaw and indicated when teeth are missing in the area of the two back molars and / or and 2nd premolar, with the above mentioned secondary condition. Since this procedure is considered a very aggressive approach (There is almost always some post operative numbness of the lower lip and jaw area, which dissipates very slowly, if ever) usually other less aggressive options are considered first, I. E. keeping the implants towards the front of the jaw.

|
Typically, we remove an outer section of the cheek side of the jawbone in order to expose the nerve and vessel canal. Then we isolate the nerve and vessel bundle in that area, and slightly pull it out to the side. At the same time we place the implants well be tracking the neurovascular bundle. Then the neurovascular bundle is released and packed back over the implants. The surgical access is refilled with a suitable bone graft material of choice and the area is closed.
|
|
These procedures may be performed separately or together, depending upon the individual’s condition. In the maxillofacial region, bone graft can be taken from inside the mouth, in the area of chin or third extensive situations, a greater quantity of bone can be attained from the hip or the outer aspect of tibia at the knee.
|
|
We can also us allograft or xenograft material to implement bone grafting for dental implants. This bone is prepared from cadvers or animals and used to get the patient’s own bone to grow into the repair site. It quite effective and very safe. Synthetic materials can also be used to stimulate bone formation. We also use factors from your own blood like PRP (APC+) to accelerate and promote bone formation in graft areas.

| These surgeries are performed in the out office surgical suite under IV sedation / general anesthesia. |
