Abstract

Objectives: Our objective was to evaluate the use of mandibular incisor extraction in relieving the lower anterior crowding and its advantages and disadvantages. Materials and Methods: A systematic review of the literature by using several electronic databases (PubMed, Medline, Cochrane library, Medline in progress, Web of science) was performed with the help of a senior health sciences librarian. The electronic search was followed up with hand searches. After applying our inclusion and exclusion criteria, the search yielded 30 articles that were then scored, based on their methodological validity. Results: Mandibular single incisor extraction proved to be an effective way of relieving the lower anterior crowding with good long-term stability. However, a proper case selection, lower inter-canine width, tooth size arch length discrepancy are some of the factors that influence the achievement of stable results. Conclusion: Mandibular incisor extraction, as discussed in this article is a good choice when all the conditions with regard to its indications are satisfied by a patient. Incisor extraction is a better choice to opt for, as the mechanics becomes simpler and good results are achievable.
