Premium Bracket Height Gauge 3.5mm–5mm for Dental Orthodontic Use

This is a 6 inches long tool marked with two height positions on each end. One side is marked with 3.5? and 5? and the other side is marked with 4.0? and 4.5?.
How to use: Place the height gauge against the tooth where the bracket will be bonded. Align the gauge with the incisal edge or occlusal surface of the tooth. Verify that the gauge is vertically aligned with the long axis of the tooth. Make sure that the height corresponds to the desired bracket position.
Once the adhesive is applied, carefully place the orthodontic bracket onto the tooth. Make sure the bracket is aligned with the height gauge and the correct position on the tooth.
