Roth technique is available in single, double, and convertible models. Will accept up to 0.045" facebow inner bows. Unlike competitive buccal tubes, Henry Schein's are built in 1 piece, and the integral weldable base is part of the design. This eliminates dangerous cheek impingements, which could be the result of base separation. All models include hooks. Available in 0.018 x 0.025 and 0.022 x 0.028 sizes.
