Abstract: A method of making a transfer apparatus includes providing a physical mockup having a shape that corresponds to a positive shape of a patient's dental arch and a positive shape of one or more appliance analogs including ramps extending in a generally gingival direction from the analog. A transfer tray may be formed over the physical mockup, with the transfer tray representing a negative replica of at least a portion of the mockup. One or more receptacles and related channels are accordingly formed in the ray, each receptacle approximating a least a portion of the shape of an appliance analog and each channel approximating at least a portion of the shape of a ramp. An appliance associated with an appliance analog is placed into a receptacle of the one or more receptacles, and the appliance may be bonded to a tooth surface of the patient's dental arch.

Abstract: Described are filter cartridges comprising: a cartridge body and a filter media; a stem extending from the cartridge body, the stem having an inlet opening, an outlet opening, and a stem face that comprises a first valve driving surface and a second valve driving surface; and at least one lug attached to either the filter body or the stem having a leading engagement edge. The filter cartridges are suitable for translational insertion and rotational engagement of a manifold, wherein upon translation insertion, a valve engagement member of the filter cartridge engages a portion of a valve body of a manifold valve; during a first stage rotation, one or more retaining members of the filter cartridge engage a manifold cam of a manifold; and during a second stage rotation, the valve engagement member imparts rotational movement to the valve body. Systems and methods incorporating the filter cartridges are disclosed.
