Study type | Interventional |
There's a scarcity in literature concerning mini-esthetics specially maxillary gingival display changes following en-masse retraction and two-step retraction. The purpose of this study is to determine, In orthodontic patients with maxillary protrusion, which technique of retraction will result in better esthetics upon smiling following en-masse retraction or two step retraction mechanics.

Secondary | Macro-esthetics evaluation of profile photograph including | 1. Nasolabial angle. 2. Mentolabial angle. 3. Incisors Inclination (Angular measurement in degrees). 4. Upper lip protrusion/ E- plane. 5. Lower lip protrusion/ E- plane. (Linear measurement in millimeters.) Cephalometric radiographs and Adobe Photoshop CC 2017 software | upto 6 months from the start of orthodontic treatment. |
