Embodiments of bone anchored expander devices described herein along with the protocol provide improved orthodontic/orthopedic appliances and protocol for expanding or contracting, protracting or retracting, extruding or intruding the upper jaw and dental arch unilaterally or bilaterally in parallel or non-parallel way, as well as enlarging the nasal cavity and nasopharyngeal airway. This expander design and protocol gives the clinician the ability to direct expansion or constriction, protraction or retraction, extrusion or intrusion forces to various segments of the maxillary jaw and arch in parallel or nonparallel configuration minimizing the need for major osteotomies.
