Factors influencing the duration of impacted maxillary canine traction: scoping review
| Resumo: | Introduction: The maxillary canine is the second most frequently impacted tooth, with a prevalence of 1 to 3% in the general population. This tooth plays an important aesthetic and functional role in occlusion, facial appearance, and arch development. As such, orthodontic traction is generally preferred over extraction or clinical monitoring without intervention. Estimating the traction duration is essential for properly defining the treatment plan. The literature identifies several variables that influence the duration of orthodontic traction treatment. Objective: This scoping review aims to synthesize the available evidence on the factors that influence the duration of traction for impacted maxillary canine. Materials and Methods: The protocol for this systematic review was registered on the Open Science Framework platform and the review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Review guidelines. A standardized search was carried out across multiple databases such as PubMed via MEDLINE, Cochrane Library, Embase, and Web of Science, as well as grey literature. Two independent reviewers assessed the articles and extracted data, which were summarised in narrative and meta-analysis formats. Results: The initial search yielded a total of 1156 studies. After removing duplicates and applying eligibility criteria based on the screening of titles, abstracts and full texts, 43 studies were included in qualitative analyses and 24 in quantitative analysis. The most commonly reported factors associated with the duration of orthodontic traction were the alpha angle, vertical height and sector. Other factors, such as patient’s age, sex, position and location and type of orthodontic treatment were less reported and still present controversial results regarding their actual influence on treatment duration. Conclusion: Several patient-related and treatment-related factors are associated with traction duration. Increased alpha angle, greater vertical height and positioning in a sector closer to the midline were associated with longer treatment duration. |
