McLaughlin and Bennett worked with Trevisi to re-design the entire bracket system to complement their proven treatment philosophy and to overcome the perceived inadequacies of the original straight-wire appliance. MBT is a version of the preadjusted bracket system specifically for use with light, continuous forces, lacebacks and bendbacks, and it was designed to work ideally with sliding mechanics. In order to complete a modern systemized method of treatment mechanics, it became necessary to address the subjects of archwire selection and force levels. This book attempts to highlight the...

The term "functional appliance" refers to a variety of appliances designed to alter the arrangement of various muscle groups that influence the function and position of the mandible in order to transmit forces to the dentition and the basal bone. Typically, these muscular forces are generated by altering the mandibular position sagittaly and vertically, resulting in orthodontic and orthopedic changes. A number of functional appliances have been developed, since the time of the "activator" developed by Andresen which offers definite advantages in growth modification to correct skeletal...
