Dento-skeletal Effects of Quadhelix Versus Mini-hyrax Expanders in Patients With Cleft Lip and Palate at the Mixed Dentition Stage: A Randomized Clinical Trial

Sponsor: Cairo University

Summary

Regarding expansion in cleft lip and palate patients, very few clinical trials were found after searching literature and fewer randomized trials. This means that no enough evidence in literature is tackling expansion in cleft lip and palate patients. To the best of our knowledge, this study will represent the first RCT to compare the dentoskeletal effects of mini-hyrax vs quadhelix. Since cleft cases usually need greater anterior than posterior expansion, both appliances are capable of anterior expansion. Nevertheless, no other study compared how much anterior expansion could be accomplished by either appliance.
