Six Month Smiles Lucid Lok® brackets and wires are included in each Patient Tray Kit™. But, you’ll need a small amount of back-up. We recommend that you carry 5 cases of brackets and wires in your “in office inventory”. On occasion, you’ll need a spare bracket or wire and this back-up inventory ensures you have what you need. The Back-up inventory includes 5 full patient cases of Lucid-Lok® brackets (including molar tubes) and 1 (10) pack each of .014, .016 and .018 NiTi wires. Additionally, it includes 1 (10) pack of .016 X .022 NiTi wires for cases in which you want to use a rectangular wire. You will be happy you have this back-up inventory (We know because we hear the stories from the dentists who didn’t have it when they needed it and wished they had)!
