Recruit Status: Completed
Study Type: Interventional

Official Title: Effects of a Finishing Protocol Implementation on the American Board of Orthodontics - Objective Grading System Score in Patients of Orthodontic Postgraduate Program: A Quasiexperimental Clinical Tria

Brief Summary: This study evaluates the effects of a finishing protocol in orthodontic outcomes using ABO-OGS scores. Patients who finish orthodontic treatment and fulfill the inclusion and exclusion criteria receive a treatment using a finishing protocol and their scores are compare with 40 patients who don't receive a finishing protocol

Detailed Summary: The phase of finishing is the most demanding and detailed of all phases of the orthodontic treatment. American Board of Orthodontics- Objective Grading system is a detailed and objective method that evaluates the quality of the final outcome of orthodontic treatment. In order to evaluate and compare the effects of a protocol implementation on the ABO-OGS scores, standardize cast models and Pan X-Ray from by convenience patients of Orthodontic Postgraduate Program of University of Antioquia who finish orthodontic treatment and receive the protocol are digitized, eight variables are evaluate and ABO-OGS score is calculate. A comparison with 40 no-protocol ABO-OGS scores by convenience-selected patients is done. The protocol includes an educate residents program about finishing problems , an standardized clinical and X-ray assessment , brackets reposition and frequent clinical evaluation. The percentage of the protocol implementation is calculate in every patient and reliability test is make . The descriptive analysis and the ABO-OGS score comparison is done by Pearson or Spearman correlation.

Current Primary Outcome: ABO-OGS Total Score [ Time Frame: Until 7 days after orthodontic appliances are removed ]

Sum of 8 variables scores ( alignment, marginal ridge height, buccolingual inclination, overjet, interproximal contact, occlusal contacts, occlusal relationships, and root angulation ) 1: difference less than 1 mm, 2: difference between 1 and 2 mm, 3: difference bigger than 2 mm . Total score less than 20: Excellent , Total score between 20-30: Acceptable and Total Score: > 30 No acceptable


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Line Smile [ Time Frame: Until 7 days after orthodontic appliances are removed ]
    Gingival exposure in smiling photo: High: More than 2 mm of gingival exposure, Media: between 2 and O mm of gingival exposure , Low: Less than clinical crown
  • Arch Smile [ Time Frame: Until 7 days after orthodontic appliances are re ]
    Relationship between incisor borders and upper lower lip border in an smiling photo


Original Secondary Outcome: Same as current
