Arms & Interventions
Extrusion arch
Hand made stainless steel extrusion arch wire (0.016x0.22")
Intervention: Extrusion arch (Device)
Outcomes
Primary Outcomes
angular and vertical linear effects on incisors
Time Frame: up to 6 months
Extrusion of upper and lower incisors measured from: incisal edge, centroid point and apex to the palatal and mandibular planes for the upper and lower incisors respectively. Angles between long axis of upper incisor to SN plane and palatal plane, Angle between long axis of lower incisor and mandibular plane using lateral cephalometric xray
angular and vertical linear effects on first molars
Time Frame: up to 6 months
For the first molars: Angular measurements between the long axis of the measuring jigs and the palatal plane and mandibular plane for the upper and lower molars, respectively. Vertical measurements: perpendicular vertical distance from the measuring jigs to the palatal and mandibular planes for the upper and lower molars, respectively, using lateral cephalometric xray.
Secondary Outcomes
- change in the Anterior facial height(up to 6 months)
- change in the SN' to Mandibular plane angle(up to 6 months)
- change in the palatal to Mandibular plane angle(up to 6 months)
