The Benex system, developed in Switzerland by Dr. Syfrig, is a pullrope extraction system that enables the gentle, atraumatic removal of dental roots avoiding fractures and preserving extraction sockets. Using the Benex system, Dr. Bolz demonstrates the extraction of upper incisors that are not worth preserving. As a retainer, an extraction screw is fixed in the root to be extracted, while the Benex system extractor is positioned exactly above the tooth using the adjacent teeth as a support. It is important that the screw and rope always have the same axial direction. The controlled force applied via the hand screw allows the root to be extracted slowly from the socket.

Following tooth extraction, a mesiodens is removed that was located in the nasal floor region. In order to achieve a clear overview, a mucoperiosteal flap is created. The area where the mesiodens was located as well as the extensive defect visible after removal of tooth 13 is filled with a resorbable bone material (“OsteoBiol”). Two membranes are placed to enhance the stability of the barrier membrane (Double membrane technique).

As optimum socket preservation is possible due to the atraumatic extraction using the Benex system, the surgeon chooses to perform immediate implantation in region 11. The remaining extraction sockets are filled with bone substitute. After suturing, a stable temporary denture is integrated and a dressing splint inserted in the palatal area.
