Profile: Invisible Technology develops orthodontic instruments. Our products include lingual pliers, KIS systems & LED light curing pens. Our product KIS system is the appliance to put the lingual brackets on set up model into their correct positions. It helps to find the exact position. It is a very precise appliance. There is no need to revise the bracket position during treatment. The bracket is accurately placed, so that we can get the best treatment result. We measure the exact torque and the axis of individual tooth in original model & the set up model using the spring-loaded pin in set up model checker. It is very easy to access. It just needs to put the pin to the Facial Axis of Clinical Crown (FACC) point of the tooth. Then the torque and the axis of that tooth are automatically measured and indicated on the scale. We can verify the symmetry on the right & left teeth. In orthodontic set up model or prosthetic model, it can mark the individual tooth position and the degree of schematic curvature of teeth in numbers.
