Personal care and hygiene formulations for topical application to mucosal surfaces. These formulations include an amphiphilic lipid carrier in the form of a colloidal composition which can include a micellar aggregate or mixed micelles dispersed in a continuous aqueous phase, or an emulsion of lipid droplets suspended in a continuous aqueous phase, and an active agent which is an anti-microbial agent. The lipid carrier has high adhesiveness to mucous membranes such as the soft tissues of the oral cavity. The lipid carrier also has a high load capacity for the active agent to be carried to these tissues. These formulations have the desirable properties of carrying a large amount of active agent for controlled and prolonged release thereof at the desired site, such as mucous membrane surfaces and surrounding tissue. Accordingly, the present invention provides a formulation for oral or topical application including an anti-microbial agent and a lipid. The agent is held by the carrier through a hydrophobic interaction and is released from the carrier in a controlled manner over a prolonged period of time. The lipid is also characterized by having a high adhesive capability towards mucous membrane surfaces. The lipid and the agent are preferably present in a ratio in a range of from about 1:10 to 10:1, more preferably from about 1:5 to about 5:1, and most preferably from about 1:3 to about 3:1 in the formulation.

The present invention provides improved devices, systems and methods for producing dental molds, each having portions representing a patient's oral soft tissue and a desired tooth configuration. These molds are designed for use in the fabrication of appliances used in orthodontic treatment, particularly, elastic repositioning appliances. However, they may also be used in the fabrication of traditional appliances, such as retainers and positioners, used, for example in the final or finishing stages of an otherwise conventional treatment. The dental molds are comprised of a mold or relief of the patient's soft tissue, such as a palate, facial gingival tissue and/or lingual gingival tissue, and a separate or separable mold or relief of the patient's dental arch having teeth in a desired tooth configuration. Since, the tooth configuration will change as a patient progresses through orthodontic treatment, the relief of the dental arch will be fabricated separately from the relief of the oral soft tissue. Typically, the dental arch relief will be fabricated using rapid prototyping methods. The soft tissue relief may also be fabricated using rapid prototyping, however it may also be fabricated using traditional mold making methods, i.e., casting with plaster or other mold making materials. In either case, the resulting dental mold with be comprised of a “split-mold” having fixedly or removably joined arch and soft tissue reliefs.
