Contensões ortodônticas fixas versus removíveis na saúde periodontal: uma revisão sistemática

Abstract

Orthodontics retainer is mandatory to maintain the corrected position of the teeth. But, the duration of use has been a dilemma in orthodontics, as there is no consensus as to the ideal duration or which type of retainer to choose, so they are often prescribed indefinitely. However, several studies indicate that prolonged restraint can pose a risk to periodontal tissues. This literature review aimed to investigate whether there is a relationship between the uso of fixed retainers and periodontal problems, through comparison with the use of removable retainers. Searches were carried out in the Medline and Lilacs databases by the VHL, Scielo and PubMed for articles from the last 25 years. After the search, 182 publications had their titles and abstracts evaluated, 9 articles met the criteria and were included for analysis. The studies indicated that there was no significant difference between the use of fixed and removable retainers in the health of periodontal tissues.
