Resumo
Objectives - To compare the efficacy and safety of three orthodontic treatment modalities for agenesis of maxillary lateral incisors: 1) closing the space with the reshaped canine substituting the lateral incisor, 2) opening the space with placement of a conventional fixed bridge, and 3) opening the space with placement of a single-unit implant and an implant-supported crown.Setting - Brazilian Cochrane Center and Universidade Federal de São Paulo, Brazil.Material and Methods - the following databases were investigated: Cochrane Register of Controlled Trials (Edition 12, 2011), EMBASE (from 1974 to December 2011), MEDLINE (from 1965 to December 2011), LILACS (from 1966 to November 2011), and Odontology Brazilian Bibliography Database (from 1966 to November 2011). Conference abstracts, main Brazilian dissertations and theses databases, and reference lists were handsearched. This systematic review included randomized or quasi-randomized controlled trials (RCTs) including women aged 15 years or over and men aged 21 years or over who received one of the interventions stated above. Two observers independently evaluated all the studies regarding eligibility criteria and assessed the risk of bias of included studies.Results - No studies were included in the review as no RCTs were found. Most of the evidence comes from case reports and narrative reviews on case reports and from three studies with a single post-intervention evaluation and non-comparable control groups with high risk of bias.Conclusions - There is no scientific evidence for any of the three most common types of treatment for agenesis of the maxillary lateral incisors. RCTs into this issue are still necessary.
