21. Example dental area MERRIMACK, NH, March 7, 2003 - Traditionally, braces on the inside of the arch are based on standard brackets and an arch wire adapted to the customer’s needs. T.O.P. Service für Lingualtechnik, a leading company in lingual orthodontics, has developed a fundamentally different production method using CAD/CAM technology. The customized brackets are much smaller and lead to magnificent results.
