Comparison of Incidence Between Two Techniques

The internal lift procedure uses a drilling instrument (a drill that cuts through bone) to break through the bone for where the implant will later go. This creates an opening in the necessary area to allow more bone material to be added, which will move the sinus up and allow for the implant to be securely placed.

The external lift procedure involves cutting through the upper-most part of the gums to then cut through the bone to create an opening in the necessary area. The sinus will be manually lifted and the bone material will be added, which will allow for the implant to be securely placed.
