US Patent 6984128 Methods for enabling and stabilizing tooth movement

Orthodontic methods comprise applying force to reposition teeth and administering a tissue remodeling and/or an angiogenic substance(s) to the periodontal tissue surrounding the teeth to be moved. The substance(s) may be delivered before, during, or after the teeth are moved, and the substance(s) may be selectively applied only to those teeth undergoing movement at any particular time. The substance(s) may be applied from the dental repositioning appliance or may be applied separately, either topically or by injection.
