The Temporary Anchorage Device (TAD) system offers fixed anchorage to assist the efficiency of your orthodontic treatment. Useful for space closure, tooth uprighting, open bite correction, molar distalization, or a number of other applications, the TAD is a versatile temporary anchorage device with both the doctor and the patient in mind. It allows your orthodontist to customize the direction of force required to move teeth. A TAD is a temporary miniature surgical screw that is placed through the gums into the bone. Once placed, it does not usually move until it is removed by your orthodontist or oral surgeon. Your orthodontist will refer you to Dr. Medel to have the TAD placed.
