Ridge preservation in the posterior maxilla

Conventional extraction frequently damages the ridge in the posterior region of the upper jaw in such a way as to considerably complicate the implantation.
The minially invasive extraction with Benex allows a one-stage approach for  sinus lift/implantation even with an elongated maxillary sinus.

Case example 1: owing to extraction with Benex sinus lift/implantation was easily possible in a one-stage approach.

Case example 2: large ridge defect due to conventional, invasive extraction
The implantation was complicated despite high subantral bone height.
