SPEED Users Guide

12 Take great care to position brackets and tubes as accurately as possible during initial bonding. If significant bracket placement errors become apparent during the course of treatment, it is better to rectify them by rebonding than to continually compensate with bends in the archwires. A meticulous bonding technique will pay worthwhile dividends later, in terms of efficiency and quality of treatment. • Always position Mandibular attachments far enough gingivally to avoid occlusal contact with the Maxillary teeth. It may be necessary, in some cases, to postpone bonding brackets to certain lower teeth or to employ a temporary bite plate. In deep overbite cases, lower incisor attachments should be positioned more gingivally. This requires an increase of built-in lingual root torque. • Unless over-rotations are required, center the brackets on the middle lobe with the mesio-distal slot axis lying tangent to the lobe’s mesio-distal curvature. Exceptions to this are the upper molars where brackets are placed on the mesial buccal cusp. • Generally, lower lateral brackets are placed on the centre of the clinical crown, while lower canine brackets are placed centrally on the middle lobe of the crown. • Due to the interaction between the SPEED Spring Clip and the initial archwires, placement errors become evident very early in treatment. This allows the novice operator to more easily “zero in” on ideal positioning and helps develop the right feel. • Always rebond brackets which have been incorrectly positioned; this eliminates wire bending and the numerous problems associated with it. • The SPEED system of in-out adapters was designed to work with the SPEED System of Coordinated Arch Forms to create ideal tooth alignment without compromising patient comfort. • Harmonious relationships of the lower anterior teeth permit the creation of flat contacts which are ideally oriented to enhance stability. Such contacts are achieved through judicious interproximal stripping after ideal relationships have been established (The small spaces created by interproximal stripping should be closed before cementing bonded lingual retainers. Sometimes it is possible to bond the lower lingual “canine-tocanine retainer early in treatment.). The flat interproximal contacts are continuous with vertical planes which all intersect at a common lingual focus. This keying together is comparable to the way a stone arch is constructed to resist collapse.
