(hard). To separate the brackets and trays from the stone model, place the model in warm water for 30 minutes. Remove the trays from the model and remove any resid-ual separating medium. Very lightly sandblast each custom pad and clean. Be careful not to gouge the base. tioning of these surfaces is mandatory. No adhesive is foolproof. The offices that experience the least amount of bond failure are the offices with the best technique. Chemical cure or light cure, direct or indirect—they all can produce desired results if handled properly. Chairside Technique Acid etch the enamel, rinse and dry. Apply one coat of Assure ® Universal Bonding Resin to each tooth and each custom pad. Lightly dry each tooth and composite base. The brackets can be transferred in the mouth with either a two-part chemical cure bonding resin (Custom IQ ® , Maximum Cure ® or Sondhi Quick Cure ® ) or a light cure flowable composite. If the two-part bonding resin is the material of choice, apply a moderate coat of part A on the teeth and part B on the bracket pads. Place the tray in the mouth and hold for 60 seconds. Wait five minutes and remove the hard tray, then the soft tray. If a light cure flowable is used, apply a layer of the paste on the gingival half of the bracket (to minimize peripheral flash) and seat tray. Light cure 10 seconds from each incisal bracket edge through the hard tray. Remove the hard tray and cure 10 seconds from the incisal bracket edge and five seconds from the gingival, mesial or distal bracket edge. Remove the soft tray. The bonding materials today that the professional has at his or her disposal are ideal to bond metal, ceramic and plastic appliances to all surfaces in the mouth.
