For dentists that conclude that a bent needle can be used safely in a particular dental procedure, the TNN Needle Guide will allow dentists to bend a Septodont Evolution needle to the 90°–120° angle needed for the TNN technique. The guides will be pre-sterilized, single-use devices and available in boxes of 100. The TNN Needle Guides are designed to work exclusively with Septodont needles and the instructions for use should be strictly followed.
