FACTORS RELATED TO ORTHODONTIC TREATMENT DURATION AT A UNIVERSITY GRADUATE PROGRAM
Objectives: This observational cross sectional study was designed to establish the average length of orthodontic treatments and relate it to multiple factors, in patients treated at the orthodontics program clinics of the University of Antioquia, finished during the years 2010-2011.
Methods: Data were obtained from clinical records, panoramic X- ray films and final dental cast from 40 patients (21 women and 19 men), 15.97 ± 5.79 year old, treated with fixed appliances. The administrative variables included: total 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. Treatment factors included: malocclusion severity, quality of finalization, tooth extractions and number orthodontic appliance issues/breakages.
Results: The average ± SD treatment duration was 55.5 ± 22.2 months. In patients with dental extractions it was significantly higher (p=0.0231) as compared to that for patients treated without extractions. 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 reparative interventions and quality of finalization).
Conclusions: Significant clinical and administrative issues were detected and it was observed that excessive time for treatment may deteriorate the static clinical results achieved.
