What this Trial Is About
This randomized controlled clinical trial aims to compare the clinical efficacy, efficiency, and biomechanical differences between two methods for total maxillary dentition distalization: (1) the use of a Sliding Jig and (2) the use of Retraction Hooks, both anchored by Infrazygomatic Crest (IZC) miniscrews. The study will assess rates of distalization, anchorage loss, dentoalveolar tipping, patient comfort, and treatment-associated side effects.
