Abstract
The purpose of this study is to evaluate the effectiveness of corticotomy treatment when compared to traditional orthodontic treatment. Effectiveness was measured by evaluating treatment outcomes, specifically improvement in occlusion and treatment duration. A retrospective study was designed to compare 46 patients who underwent selective alveolar corticotomy to 80 patients who received traditional orthodontic therapy provided by four private practitioners in the U.S. Cases were compared using three commonly used orthodontic indices to determine case complexity and occlusal outcome: Peer Assessment Rating, Objective Grading System, and Discrepancy Index. Results indicated that patients in the corticotomy group on average were 23 years older than patients in the traditional treatment group. After controlling for confounders at baseline, there were no differences between corticotomy and traditional treatment group as measured by PAR score and Discrepancy Index. After controlling for confounders such as gender, age, race, tooth extraction and dentition pattern using linear regression, it was found that cases in the corticotomy group had treatment times 2.4 times shorter than those in the traditional group (p[less than]0.0001). After controlling for confounders, no difference in occlusal outcome was found between corticotomy and traditional treatment when measured using OGS and the PAR index. Further studies will be required to address the limitations of our study and to verify our findings.
