AMAYA, Suly et al. Effectiveness of temporary skeletal anchorage for space closure: A systematic review. CES odontol. [online]. 2011, vol.24, n.2, pp.49-58. ISSN 0120-971X.

Introduction and Objetive: Anchorage management is essential for successful fi xed orthodontic treatment; however there is no consensus about the effectiveness of skeletal anchorage for anterior teeth retraction. The aim of this review was to evaluate the effectiveness of skeletal anchorage for space closure in the maxillary arch. Materials and Methods: A systematic review of the literature was performed in PubMed, Cochrane, Lilacs, Scielo databases. Controlled clinical trials were included, where skeletal anchorage was used for space closure. Three reviewers examined the abstracts and full texts to determine fulfillment of the inclusion and exclusion criteria independently in a data extraction form. Results: 324 papers, out of which 316 were excluded after the evaluation of title and abstract of the eight initially selected trials. Only three trials met the inclusion criteria. A meta-analysis was performed with a random effects method for the mesial movement of upper molars in which the temporary skeletal anchorage devices showed to be more significantly more effective in controlling anchorage -2,7 mm (-4,10,-1,33 CI 95%) when compared to the conventional anchorage control methods. Conclusions: Temporary skeletal anchorage seems to be more effective in controlling the movement of molars during mesial space closure, when compared to the conventional orthodontic anchorage although evidence in the literature is limited.
