Objetivo: El propósito de la presente revisión de literatura fue comparar la reabsorción radicular apical externa (RRAE) que producen los brackets de autoligado pasivo con los brackets convencionales. Métodos: Se realizó la búsqueda bibliográfica utilizando las bases de datos de PubMed, Embase, Scopus y ScienceDirect de los estudios que compararon la RRAE entre pacientes de ortodoncia que usaban brackets de autoligado pasivo o convencionales mediante radiografías panorámicas, periapicales o CBCT hasta enero del 2023. Los términos de búsqueda fueron “root resorption” AND “passive self-ligating brackets” AND “orthodontic brackets”. Resultados: No se encontraron diferencias significativas en la RRAE entre los brackets de autoligado pasivo y los brackets convencionales. Conclusión: Los brackets de autoligado pasivo y los brackets convencionales producen reabsorción r...

Orthodontists must fully inform patients about the implications of orthodontic treatment and the subsequent need for retention. This review provides an update on relapse, unwanted movements, and different factors that can cause loss of stability following orthodontic treatment. Since it is difficult to predict which patients will present some degree of loss of stability after treatment, it is essential that they be treated as if they have a high potential for relapse. The present review included a bibliographic search in the main sources of scientific review including Medline via PubMed, Scopus, and the Cochrane library. The search strategy was carried out until May 5, 2022. Only 34 studies fulfilled the selection criteria. Our results showed that maintaining teeth in the correct position following orthodontic treatment is a great challenge for orthodontists. The etiology of relapse is c...
