The maxillary and mandibular teeth were levelled and aligned in 4 months.
Figure 7.
A micro-screw was inserted between maxillary central incisors in the mucogingival junction and assisted in intruding the anterior teeth.

(A) pretreatment facial smile photograph; (B) posttreatment facial smile photograph: the ‘gummy’ smile was corrected after 3 months’ intrusion of the maxillary anterior teeth.

(A) pretreatment facial profile photograph; (B–D) treatment facial profile photographs; (E) posttreatment facial profile photograph: the profile of the patient changed from convex to straight and a better-defined cervical-mental angle was created.
Cephalometric superimpositions of the initial (black), final (red) lateral cephalometric tracings: (A) centered on the cranial base; (B) centered on the palatal plane; (C) centered on the mandibular symphysis.

(A) ribbon-wise arch wire; (B) traditional orthodontic wire: the ribbon-wise arch wire has a greater width than height in cross-section which makes the wire harder to bend in the vertical direction.
