title: Single arch extraction--upper first molars or what to do when nonextraction treatment fails.
abstract: The logical goal of treatment must be to correct a malocclusion to the nearest possible approach in all respects to a normal condition as we understand it. When extraction within the upper arch only is the desired treatment plan, removal of two upper first molars will produce the closest approach to normalcy in terms of the dentition's function, its health, its influence on facial features, and its appearance. With the removal of upper first molars for treatment purposes, the result will be a dentition that has all the magnificent appearance of a dentition that never had any extractions at all. It will be a dentition that can have good functional movements at the end of treatment and on into the posttreatment period.
