The sinuses are air spaces in your skull and facial bones that make up the upper part of your respiratory tract from your nose into your throat. The floor of the maxillary sinus is close to the roots of your upper molar teeth. A sinus lift may be needed if there is insufficient bone on your upper jaw for dental implants to be placed. It is a surgical procedure that involves moving the sinus membrane upward in the upper jaw. This then allows for bone to be added to the area surrounding the upper molar and pre molars. There are several reasons for bone loss, some may include:
- Periodontal (gum) disease
- If teeth have been extracted and have been missing for a long time, bone may begin to be resorbed back into the body
After this procedure, it will take about 6 months of healing before the bone has fully integrated into the jaw. The next stage of the restoration can follow, either the insertion of an implant, or whatever else has been agreed between you and the dentist.
