Abstract
Provided, among other things, is a system for progressive palatal expansion, the system comprising a series of incremental expanders, including: a) a first incremental expander having a geometry selected to incrementally expand the palate; b) one or more intermediate expanders having geometries selected to progressively expand the palate; and, c) a final expander, having a geometry selected to expand the palate to a target desired breadth.

A system for progressive palatal expansion, the system comprising a series of incremental expanders, including:
- a) a first incremental expander having a geometry selected to incrementally expand the palate;
- b) one or more intermediate expanders having geometries selected to progressively expand the palate;
- and, c) a final expander, having a geometry selected to expand the palate to a target desired breadth.
A method of expanding the palate of a patient, the method comprising:
- a) generating from an initial physical or electronic model of the patient's upper jaw a series of incremental expanders, including:
- i) a first incremental expander having a geometry selected to incrementally expand the palate;
- ii) one or more intermediate expanders having geometries selected to progressively expand the palate;
- and, iii) a final expander, having a geometry selected to expand the palate to a target desired breadth;
- and b) sequentially engaging the expanders with the patient's upper jaw, each for a period of time effective, over the course of treatment, to expand the palate to approximately the target desired breadth.
