Actual date on which the first participant was enrolled.

This clinical trial aims to explore the effectiveness of two different types of dental appliances used for correcting teeth alignment in the upper jaw, specifically focusing on patients who need their upper teeth moved backwards (a process known as distalization). The study targets individuals who require orthodontic treatment to achieve proper bite alignment, which is important for both functionality and aesthetics. By comparing two different approaches—one using a device anchored to the cheek side and the other using a device anchored to the palate—the study seeks to identify which technique is more effective and comfortable for patients. This could potentially lead to improved orthodontic treatments for individuals requiring significant dental corrections. Participants in this study will be divided into two groups, each receiving a different type of dental appliance. The first group will have a device anchored with small screws placed near the cheekbones, while the second group's device will use screws placed in the roof of the mouth. Both devices are designed to be bonded to the back teeth and use elastic chains to gently move the teeth into the desired position. The force applied will be carefully measured to ensure safety, and adjustments will be made during regular follow-up appointments every three weeks. The treatment continues until a proper bite alignment is achieved, at which point the devices are removed. Throughout the study, participants' progress is monitored with dental X-rays taken before and after the treatment to assess the changes.
