Internal Sinus Lift
A common technique done when the sinuses limit the amount of bone available for a dental implant, the sinus membrane can be pushed upward and grafting bone material is added to increase its volume. This will allow for dental implants to be placed.
Lateral Sinus Lift
Lateral wall sinus augmentation has traditionally consisted of creating a window in the lateral wall with surgical handpiece or piezosurgery device to lift the sinus membrane when loss of teeth provides inadequate volume of bone, specifically related to height. Additionally, hand instruments are required to elevate the sinus membrane from the bony floor and lateral/medial walls to create an area that will accommodate the graft augmentation to be placed.
