There was no intention originally to produce a new appliance, but the need for one became evident.       The arising concept was to Pre-program suitable treatment into the appliance and therefore the SWA was developed. The built-in features of the SWA guide the teeth along direct vector lines, eliminating jiggling, round-tripping and other excessive movements. Andrews’s philosophy of treatment     A bracket type for each tooth type:       Since within any dentition, teeth differ from each other, therefore, each tooth would require its own bracket.    Measurements of the non-orthodontic normal models had provided data about the angular positions of crowns in excell

Different authors had reported different methods in an attempt to determine the best indicator of maturity. These include height weight; chronological age sexual maturation , Frontal sinus, biological age or physiological age; Hand-wrist maturity Cervical vertebrae dental eruption; dental calcification stages, and recently biomarkers. Requirement of an ideal maturity indicator Should be safe and non invasive Require minimum radiation Should be accurate Stage of maturity should be well defined Easily identifiable Cost effective Require minimum armanterium Simple to conduct Valid overtime and across age group 1-Biological age or physiological age The physiological age of a person is determined by the degree of maturation of the different tissue systems. Physiological age can be
