Abstract: Embodiments include dental appliances, dental appliance systems, and methods of making and using such appliances. In one embodiment, a dental appliance includes a shell having a number of cavities to receive one or more teeth, each cavity having an inner surface. Fewer than all cavities are scaled-up in size by a first selected percentage over one or more dimensions of a corresponding tooth surface to provide a uniform space between the cavity inner surface and the corresponding tooth surface.

Abstract: Methods of treatment of a dentition using a dental appliance including a scaled-up cavity to establish a space between an inner surface of the scaled-up cavity and a tooth. The space may be adapted to accept a chemical to chemically treat the tooth. The scaled-up cavity may have a spacer configured to maintain the space between the inner surface of the scaled-up cavity and the tooth. The dental appliance may also include a fitted cavity configured to snuggly fit on another tooth to create a fixed orientation of the dental appliance with respect to the dentition, for example, to ensure that the chemical within the space is in contact with the tooth.
