Abstract: An invisible removable orthodontic repositioning appliance with a lower modulus inner lining for systematically aligning teeth from an initial tooth arrangement to a final tooth arrangement while minimizing propensity for root and bone resorption due to the lower modulus is disclosed. The aligning of the teeth may be accomplished by taking impressions at various intervals for greater accuracy in the event of a distorted impression. Patient impression and/or model may then be digitally scanned. Using 3D software, tooth position may be incrementally modified toward idealized position and associated stress analyzed. Final modified model and associated appliance may be fabricated for orthodontic movement using 3D printing. Each appliance may be numerically identified to maintain uniformity of application from start of treatment to completion.

Abstract: The invention relates to a dissolving strip for drug delivery providing a generally inert water soluble base material attached to the maxillary molars in order to deliver a therapeutic material upon activation by the parotid and other oral salivary glands. The composition of the dissolving strip is a generally inert base material, such as pullulan. The pullulan is impregnated with a therapeutic material to form a solid mixture to carry the therapeutic agent. The dissolving strip has sufficient flexibility to adhere to the 1-4 maxillary molars and acts as a reservoir to deliver therapeutic agents, such as an anti-smoking formula, a diet formula, a sexual enhancement formula, an oral freshness formula, prescription drugs, non-prescription drugs, herbs, or vitamins, or any combination of the previously listed. The dissolving strip is capable of delivering the therapeutic agents in a sustained or time released fashion.
