简要总结
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.
详细描述
This study will be conducted in order to evaluate which technique of retraction will provide better outcome regarding mini and macro esthetics. In terms of mini esthetics, posed smiles will be analyzed to evaluate maxillary gingival display, as well as the analysis of smile arc, buccal corridor, inter-labial gap. In terms of macro esthetics, frontal and profile poses will be assessed to evaluate the nasolabial angle, mentolabial angle and upper and lower lip protrusion/ E- plane.
