TADS (Temporary Anchorage Devices)          TADS are small screws that can be placed directly into the bone to create greater anchorage options for moving teeth. The use of these screws can greatly enhance the possibilities of moving teeth in ways that could never be considered in the past. These TADs will , without question, be an oft-used adjunct to future treatments, and more uses are still being developed. TADS can be placed in the office with only the use of a local anaesthetic. They are also very easily removed. IMPLANTS          Inplants were first used in the late 1970's to replace lost posterior teeth, and were used orthodontically prior to placement of a crown on the implant to create absolute anchorage for moving teeth. These implants used for orthodontic anchorage were the predecessors to the TADS mentioned above and the effectiveness of the implants directly led to the much more easily placed TADS. Implants require precise placement as they are generally not removable. ORTHOGNATHIC SURGERY           The term orthognathic surgery refers to the combination of surgical and orthodontic treatment in a planned and coordinated manner to correct severe skeletal deformities. The planned orthodontic movements for a surgical correction of a jaw problem may mean the removal of dental compensations that developed during the patient's skeletal growth. This orthodontic preparation is frequently opposite of the treatment used when using orthodontics alone to correct the bite problem. This is an area of expertise taught by Dr. Skarin during his years teaching at Northwestern.
