AnatomicTwist Twist holder for dental technicians. The AnatomicTwist is a universal twist holder for rotary instrument inserts. It has been designed to optimally fit the anatomical shape of the hand. The red section of the AnatomicTwist is made from aluminium alloy, producing a much lighter instrument. The instrument socket is made from stainless steel and has a rotary bearing. This socket is connected maintenance-free to the instrument body and ensures smooth, controlled rotation. The lightweight design of the red section combined with the stainless steel instrument socket section produces a top-heavy instrument. This fact guarantees optimum guidance while working with cutting and rotary trimming instruments preparating dental implant abutments.
