Implant success depends on the quantity and quality of the bone the implant is placed in.
Traditionally, the upper back jaw has been one of the most difficult areas to successfully place dental implants due to insufficient quantity and quality of bone. Bone in this area tends to be less dense than in other areas of your jaw. In addition, when an upper molar is lost, your maxillary sinuses, which are behind your cheeks and above your upper molars, pneumatized, or expand downward.
Utilizing this technique, the maxillary sinus floor is entered from the place where the upper teeth used to be. A small window is made to allow visualization of the sinus membrane, which lines the maxillary sinus.
The sinus membrane is then elevated upward and donor bone is inserted into the floor of the maxillary sinus. The site is then closed and sutures are placed. After several months of healing (typically 6 months), the bone becomes part of your upper jaw, creating the vertical bone height necessary for implant placement. At this stage, dental implants can be placed and will be stabilized within this new, grafted bone.

These x-rays show loss of vertical bone height following extraction of the premolar teeth on both sides of the patient’s mouth.
The bone that occupied these teeth has shrunk causing reduced vertical bone dimension. In this case, there is approximately 5 mm of jawbone remaining below the maxillary sinus floor. The second x-rays show an increase in vertical bone dimension 5 months following antral sinus augmentation allowing for dental implant placement.
