2INGIS's unique patented guiding system offers many advantages compared to conventional guiding systems.

• The two outer guiding rails enable quiet and friction-less drill movements. Cooling is possible from the top or from the sides.

• Because of the drill sleeve geometry drilling holes can be opened on the side to allow for exact guiding in situations with little available space.

• The 2INGIS drill sleeves are located on the side of the bone (instead of on top of the bone). This leads to a few more millimeters space in the vertical dimension. If the mouth opening isn't enough a distal long hole can be added to the 2INGIS drill sleeves to get the necessary space for the drill.
