      Preface

      Many people believe that we are in the age of straight archwires and that wire bending is no longer necessary. However, the straight wire technique, in which a thin elastic straight wire is inserted and replaced by increasingly thicker wires, does not allow adjustments according to the unique skeletal morphology, dysfunction, tooth size, and dentition of each patient as well as the patient’s age, sex, and wishes. If such adjustments are not necessary, treatment results should be the same in all cases, but this is not reality. Nevertheless, it is true that recent advances in wire properties have changed clinical techniques, and the development of wire with high resilience has reduced (but not eliminated) the necessity of bending.

      Another consideration is bracket design. The force of wire is transmitted to the periodontal tissue and alveolar bone via the brackets attached to the teeth, and the morphology and size of brackets differ according to the developer of each technique and among manufacturers. Though each bracket has torque, angulation, in/out, and morphology based on its original design, it is strange that only one type is used for most techniques, without alteration for the unique needs of each patient. There are only some brackets in which angulation and torque differ depending on whether or not tooth extraction is included in the treatment plan. Setting the skeletal morphology and function of each
