Resorption of roots in conventional braces versus advanced aligners: A comparative study

External apical root resorption (EARR) remains a common and clinically relevant iatrogenic consequence of orthodontic treatment and uncertainty persists regarding whether modern clear aligner systems reduce this risk compared with conventional fixed appliances. Therefore, it is of interest to evaluate the radiographic alterations in the root length of patients using conventional braces to patients with the new generation aligners. There was a significant resorption in both groups although it was a mild one in clinicallee where the mean reduction is more in patients with fixed appliances. Data show evidence in favor of aligner therapy as a possible option in reducing orthodontic roots resorption.
