SUB-ANTRIAL BONE AUGMENTATION
Also known as a “sinus lift,” sub-antrial bone augmentation is a surgical procedure that adds bone to your upper jaw in the area of your molars and premolars to make the jaw taller. The sinus membrane is moved upward, or “lifted” to make room for the bone that is added between your jaw and the maxillary sinuses, which are on either side of your nose.
There are three common reasons for a “sinus lift:”
- Multiple tooth loss in the upper jaw has resulted in insufficient bone being present for implants to be placed
- Bone loss due to periodontal disease
- The maxillary sinus may be too close to the upper jaw for implants to be placed
The bone used in the sinus lift may come from your own body (autogenous bone), from a cadaver (purified allogeneic bone) or sometimes synthetic materials (alloplasts) which stimulate bone formation are also used.
