What is a Sinus lift?
Typically this procedure is needed when patient is preparing for dental implantation. Maxillary sinus floor augmentation (also termed sinus lift, sinus graft, sinus augmentation or sinus procedure) is a surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane (sinus membrane) and placing a bone graft.
When the procedure is needed?
Patients who have the following may be good candidates for sinus augmentation.
- Lost more than one tooth in the posterior maxilla.
- Lost a significant amount of bone in the posterior maxilla.
- Missing teeth due to genetics or birth defect.
- Minus most of the maxillary teeth and need a strong sinus floor for multiple implants.
It is not known if using sinus lift techniques is more successful than using short implants for reducing the number of artificial teeth or dental implant failures up to a year after teeth/implant placement.
