The SPEED system: a report on the development of a new edgewise appliance.
The aim of this presentation is to acquaint the reader with the design characteristics of the primary components of the SPEED appliance and to provide an explanation of the manner in which it functions. The bracket body, mounted spring clip, and bonding pad assemblies permit the application of corrective forces to teeth and their supporting structures without the need for arch-wire-ligating materials. The spring and arch slot geometry has been designed to reduce sliding friction and to enhance the three-dimensional control of tooth movement. Despite their small size, SPEED brackets have provision for a wide variety of auxiliaries. It is possible to secure uprighting springs and several types of elastic hooks to individual brackets. As of Jan. 1, 1980, more than 600 patients had undergone treatment with the SPEED appliance. Many of these cases are extensively documented with serial photographs.
