Factors related to Orthodontic Treatment Duration at a University Graduate Program
Introduction: To establish the relationship between orthodontic treatment time with educational/administrative/clinical factors, in patients treated and finished, at the orthodontics program clinic of an University.
Methods: Data were obtained from clinical records, panoramic radiographs and final dental cast from 40 treated patients (21 women and 19 men), 15.97 ± 5.79 years old. The administrative variables included: number of accomplished appointments, number of appointments per year of treatment, total number of missed appointments, total months of treatment, number of effective months of treatment, number of residents and instructors attending the patients and percentage of treatment planning for next appointment. Clinical variables included: malocclusion complexity, quality of finalization, teeth extractions, age and number of orthodontic appliance issues/breakages.
Results: The average ± SD treatment duration was 55.5 ± 22.2 months. In patients with dental extractions, treatment time was significantly higher (p=0.0231). A model of multiple linear regression explained 59% of the variability, identifying four significant variables, two related to administration (number of missed appointments and number of instructors) and two clinical variables (number of orthodontic appliance issues/breakages and quality of finalization).
Conclusion: Significant clinical and administrative issues were detected and it was observed that excessive time for treatment may deteriorate the static clinical results achieved.
