  1. An edgewise type of a bracket is used. These brackets provide greater control over tooth movement Horizontal slot is seen. A Ribbon arch type of bracket is used. The bracket brings about tipping of teeth in labio-lingual as well as mesio-distal direction. Vertical slot is seen Brackets

  2. There is a wide mesio distal dimension of slot. There is increase in forces to the roots. There is a forward moving of arches see. There is a less mesio distal dimension of slot. The force is thus rarely transmitted to the root. There is no forward moving of arches. Brackets comparison

  3. Andrews concept was of placing brackets on midpoint of long axis of clinical crown, but it had many disadvantages. Tweed advocated placing brackets by mm measurement from the bracket slot to incisal edges of anterior teeth. upper arch lower arch 4.5 4 4 4 5 4.5 4&5 4.5 5 6&7 3.5 4 Brackets centeredmesiodistally on labial or buccal surfaces of teeth with base of arch wire slot 4mm from incisal edges or cusp tips. Exception is maxillary lateral incisor. Positioning of brackets

  4. Brackets have slot dimensions of 0.018x0.030 or 0.022x0.030 inch. Bondable and weldable brackets are available. Brackets are manufactured to accept 0.016 inch diameter round arch wire. Specifications of the bracket
