Abstract
The purpose of this study is to evaluate whether patients who undergo selective alveolar corticotomy as part of their orthodontic treatment have similar overall outcomes as patients who undergo traditional therapies. A retrospective study was designed to compare 52 patients who underwent selective alveolar corticotomy with Drs. TM Wilcko and WM Wilcko in their private practices in Erie, Pennsylvania to 93 patients who received traditional orthodontics completed by graduate orthodontic students at the University of Oklahoma School of Dentistry in Oklahoma City, Oklahoma. Cases were compared using three commonly used orthodontics indices to determine case complexity and occlusal treatment outcome: Peer Assessment Rating, the Objective Grading System and the Discrepancy Index. Results indicated that patients in the corticotomy group on average tended to be 17 years older than patients in the traditional treatment group. After controlling for confounders (such as gender, age, extractions, and dentition pattern) using linear regression, it was found that patients in the corticotomy sample had treatment times one-third shorter than those in the traditional group (p [less than] 0.001). Pretreatment PAR scores and discrepancy index results show that the traditional cases were more complex than those in the corticotomy group. However, after controlling for confounders, no differences in the two groups were noted. After controlling for confounders, no change in occlusal outcome between corticotomy and traditional treatment when measured using OGS and the PAR index were found. While corticotomy looks to be an exciting means of treatment as it shortens treatment duration, there was no difference noted between the occlusal outcomes between the two treatment groups. Further studies will be required to address limitations of the current study such as a wider patient sample for corticotomy cases, cases need to be done by different providers and retention results need to be analyzed to determine the consistency of these findings.
