## DAMASCUS, Syria: The use of clear aligners in mild to moderate cases of malocclusion has been the subject of numerous studies, particularly as more dentists make the decision to begin offering their own in-house aligner options. However, a team at the Damascus University dental school has conducted a trial that will add to the limited body of literature on the efficacy of in-house clear aligners versus conventional fixed appliances in more complex occlusion cases. The study found no significant difference between the results of either group and attributed the success of the aligners to a new treatment protocol designed for the study.
