title: [The extraction of a lower incisor in orthodontics: indications, planning of             the treatment and clinical handling in different malocclusions].
abstract: The extraction of a lower incisor has been a therapeutic approach considered           controversial in orthodontics over the last decades and, therefore, supported by some           authors and questioned by others. In recent years, different publications have attempted           to provide with substantial and structured information that could help to perform this           atypical form of therapy in selected cases with a prospective good result. The purpose of           this article is to summarise the available information, providing an order and structure           to the diagnostic features that could support the indication and use of this treatment           alternative, including the quantification of those parameters that can be measured in the           decision-making process. Finally, to set up a clear and meaningful clinical frame that           could be used by the orthodontist as a reference line in daily practice. Four case reports           will be used in order to illustrate the indication of this treatment modality in different           malocclusions.
