Can a different bracket setup save tooth roots during braces?

This trial compares three orthodontic techniques for pulling the upper front teeth backward in adults with Class II malocclusion. All methods use small temporary screws for anchorage, but they differ in bracket design and archwire setup. The goal is to see which approach causes the least root shortening, a common side effect of braces. Sixty adults will be randomly assigned to one of the three methods, and X-rays will track root length changes over time.
