• Let the putty set for 5 minutes, immerse in water for 1 hour and remove bracket tray from the model. Trim silicone tray just under the bracket’s mesh pad and make three indents on the occlusal of the indirect bonding tray. For greater rigidity, the bonding tray’s hard “outer shell” should be made with Fastray (Bosworth). Mark the midline to facilitate proper placement. CHAIRSIDE PROCEDURE Remove the indirect trays from the stone model. Examine the trays carefully for remaining stone covering the adhesive “custom base” on each bracket. Use a scaler to remove any stone from the custom adhesive bases. Be careful not to abrade the resin base. Apply acetone to adhesive bases and air dry them. Prepare teeth for bonding by following normal tooth preparation procedures. Make sure that saliva does not contact the etched enamel. Bonding is accomplished with bonding resin, therefore all visible moisture should be removed. The etched teeth should have a frosty appearance and be completely desiccated. Small amounts of Phase II Resin A and B liquids should be poured into plastic mixing wells. Resin A can be painted onto the tooth surface with a brush, and Resin B can be painted, in the same way, on the resin pads in the indirect bonding tray. Position the tray over the teeth and seat the tray. Apply equal pressure to the occlusal, labial and buccal surfaces. Hold for a minimum of 2 minutes. Allow 2 more minutes of cure time before removing the tray. This procedure is now repeated for the opposite arch. Upon tray removal verify that there is not an excess of resin obstructing the SPEED Spring Clip. If necessary, scale off any excess resin around the brackets and from the interproximal contacts. Use dental floss interproximally to ensure that all contacts are free. SPEED SYSTEM OF COORDINATED ARCH FORMS The SPEED System of Coordinated Arch Forms, developed by Dr. G. H. Hanson (SPEED Inventor), is based on his in-depth analysis and twenty years of clinical experience with the SPEED System™. The archforms reflect the subtle nuances of SPEED’s sophisticated standoffs which allow the archwire to sit as close as possible to the teeth. They provide optimal tooth positioning for all phases of tooth movement from unravelling and aligning to finishing and retention. Clinically proven, these archforms provide beautifully coordinated upper and lower arches without any modification of the form as received.
