MIDLINE MINI IMPLANT-ASSISTED CORRECTION OF VERTICAL MAXILLARY EXCESS -A CASE REPORT

Abstract

The correction of Vertical maxillary excess is more difcult and challenging than the correction of antero-posterior, or transverse malocclusion.
This article describes the orthodontic treatment of a 24-year-old male patient with increased incisor visibility at rest. He was diagnosed as Angle's
Class I malocclusion on a Class II skeletal base with sagitto-vertical maxillary excess and orthognathic mandible with proclination and crowding of
upper and lower anteriors. Soft tissue parameters revealed convex prole. Fixed appliance treatment was started with four rst premolar extraction
and alignment and levelling, followed by simultaneous intrusion and retraction of the anteriors with the help of midline mini-implant which
resulted in achieving all the treatment objectives. The active treatment period was 18 months. The incisor exposure at rest and upper and lower
proclination were corrected and better facial and smile esthetics was achieved.
