• Lines of reflected light on the highly polished surfaces of the Spring Clips serve as excellent labial or occlusal placement guides. They are always parallel to the mesio-distal slot axis. 11 The SPEED Spring Clip provides control during bodily translation thus ensuring excellent root parallelism. Occlusal reflection lines may be used for incisor positioning. Reflection lines on the labial of the Spring Clips can be used to aid in slot alignment. It is easy to initially underestimate the effectiveness of the SPEED Spring Clip. These early SPEED prototype brackets were placed with their slots tipped into the extraction sites. Once positioned correctly, the brackets realigned the roots and crowns into their proper position. • Pressing bicuspid brackets into place without rotational restraint during bonding causes them to spin until the axis of bend of the bonding base aligns with the long axis of the middle lobe of the tooth. A light force to tease the brackets into more or less tip angulation must be used with care to avoid pulling the pad away from the tooth in the middle area thereby creating a void. • The upper brackets are positioned to conform to an archwire plane compatible with brackets placed as far gingivally as possible on the typically short clinical crowns of upper second bicuspids in 12-13 year old children. • It is not necessary to angulate bracket slots into extraction sites or to use special extraction series brackets. Excellent root parallelism is maintained during extraction space closure without changing bracket angulation from the ideal because of the unique action of the Spring Clips in restoring a close fit between the archwire and the entire length of the occlusal wall of the archwire slot even after the smallest amount of crown tipping.
