    The following depictions represent some of the most common uses

    for skeletal anchorage in clinical treatment at the present time. They

    are byno means the sum total of all the possible uses for TADs.

    Likewise, the Biomechanics shown in the case examples should

    notbe considered as the onlymethod of choice possible. It is left to

    the clinician to determine how to best treat each specific case andthe proper Biomechanics to use based on his/her training and case

    analysis and treatment plan.
