There are two types of sinus lift procedures: the external sinus lift and the internal sinus lift. Dr. Kwok will assess your situation and discuss your options prior to the procedure.

In one form of the sinus lift procedure, the external sinus lift, a small opening is created laterally in the bone to access the sinus cavity to gently lift the sinus. This procedure helps to encourage natural bone growth to fill the space created, but a bone grafting material is often placed beneath the newly raised sinus cavity along the existing bone. This grafting material will essentially hold the space until your body is ready to create new bone in the area.

External Sinus Lift


A second form of the sinus lift procedure, the internal sinus lift, involves gaining access to the sinus cavity through a vertical internal opening created in the bone. Bone is added to the floor of the sinus to increase the bone height. The sinus is thus filled to increase the bone to a sufficient thickness that can eventually support an implant.

If you have any questions about whether a sinus lift is the right treatment for you, please call us today to schedule your consultation with Dr. Kwok.
