A Sinus Elevation, or Sinus Lift, is a surgery that is designed to increase the quantity of bone available in the maxilla (upper jaw bone) for implant placement. The sinus floor is gently elevated and bone grafting material is placed into the newly created space to augment the jaw bone.
There are two forms of sinus elevation surgery: an internal sinus lift and an external sinus lift. The type of sinus lift required depends upon the amount of native bone present at the time of surgery.
The posterior maxilla has been one of the most difficult areas to place dental implants successfully because there is often insufficient bone for implant placement. When the maxillary teeth are lost or there is bone loss due to periodontal disease, the distance between the sinus floor and the alveolar ridge decreases, leaving less bone for implant placement. A sinus lift helps to correct this problem.
Sinus elevation takes approximately 4-9 months to heal at which time implants can be placed. However, if there is adequate bone present at the time of sinus elevation surgery the implants may be placed simultaneously.
