Apiñamiento dental anteroinferior y su relación con los tercero molares. Revisión de la literatura

Abstract

Crowding is a reduction in the perimeter of the arch, which can manifest itself as closure of the space due to movement of the teeth, related to a connection between the size ofthe teeth, genetic and local factors and the eruption of the third molars in a mesioangular or horizontal direction, within the dental arch producing forces that are directed in a mesial direction and these affect adjacent molars and adjacent teeth. The aim of this study is to evaluate dental crowding and its relationship with the eruption of mandibular third molars, trying to find the best explanation for these two situations that could be related. A review of the literature was carried out in digital databases: Google Scholar, Web of Science, SciELO, EBSCO, Scopus as well as: MEDLINE-PubMed, Elsevier, Springer Open, Taylor & Francis. The inclusion and exclusion criteria were applied and 40 articles were selected with a maximum of 8 years since first published. Results show it was possible to identify that the third molar 'is not related to anteroinferior crowding, and exodontia is indicated as a preventive method, evaluating each case. To sum up, the third molar does not influence crowding, this is related to the difference between the length of the arch and the size of the teeth among other factors. Mesialization of the second molars and premolars is also present and the interproximal space 'is reduced due to the force exerted by the third molar.
