When a tooth is lost, the vacant tooth socket collapses, leaving a loss in both height and width of surrounding bone. When an upper molar or premolar is lost, the floor of the upper sinus expands, which further reduces the thickness of the underlying bone. The result is a loss of space in which to place dental implants. Sinus lifts create additional space for dental implants by either grafting extra bone near the sinus or in some cases by tapping near the sinus floor with surgical instruments to lift the sinus membrane.
Undergoing sinus lift surgery has allowed many patients to have successful dental implants treatments, in particular the all on 4 and all on 6 techniques. In most cases, dental implants can be placed during the sinus lift procedure, minimizing discomfort of multiple surgeries.
