---|---|---|---|---|
Primary | angular and vertical linear effects on incisors | 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 | up to 6 months | |
Primary | angular and vertical linear effects on first molars | 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. | up to 6 months | |
Secondary | change in the SN' to Mandibular plane angle | measuring the change in the angle between SN' to Mandibular plane angle, using lateral cephalometric xray | up to 6 months | |
Secondary | change in the palatal to Mandibular plane angle | measuring the change in the angle between the palatal to Mandibular plane angle, using lateral cephalometric xray | up to 6 months | |
Secondary | change in the Anterior facial height | measuring the change in the vertical distance between Nasion and Menton, using lateral cephalometric x-ray. | up to 6 months |
