Medical Forum / General / Dentistry / January 2005Can invisalign aligners be used for bleaching?
I got a free bleaching kit with my invilalign treatment and was wondering if I can use my aligner instead of the trays that came with the bleaching kit. Thanks. > I got a free bleaching kit with my invilalign treatment and was wondering > if I can use my aligner instead of the trays that came with the bleaching > kit. > > Thanks. The bleaching trays are made to cover the entire enamel surfaces of the teeth. The aligners are usually made to cover only a portion of the teeth, so bleach used in the aligners would whiten only that part of the teeth. Using the aligners as bleach trays might result in an interesting two-tone pattern on the enamel. ;-) - dentaldoc >>I got a free bleaching kit with my invilalign treatment and was > [quoted text clipped - 17 lines] > > - dentaldoc My aligners cover all coronal surfaces.

What form do your aligners take in places with severe undercuts? When I took the Invisalign intro seminar, severely-tilted teeth were not fully covered all the way to the gingival margin in those cases where the path of insertion would not permit it. This was no problem from an orthodontic standpoint, but would limit the amount of bleach that tooth would receive if the aligner were used as a bleaching tray. Most flexible bleaching trays extend 0.5 - 1.0 mm onto the gigiva. This ensures full bleaching power without undue exposure of the gingivae to the peroxide. Do the aligners cover as much, or do they end right at the gingival margin? I don't know what the effect of 20% or stronger carbamide peroxide would be on the aligner material. It shouldn't be a problem, but you never know unless it has been studied. - dentaldoc >>>>I got a free bleaching kit with my invilalign treatment and was >>> [quoted text clipped - 49 lines] > > - dentaldoc I hadn't thought of severely tilted teeth--I had tilted teeth, but they managed to cover the entire coronal surface. They end pretty much at the gingival margin. I haven't used bleaches over 15%, but remember the aligners only have to hold up for 2 weeks. ;-) I am wearing the heavier guage retainers now, and they're slowly disintegrating. I used a calculus-removing solution in my ultrasonic cleaner--don't know if that was the problem, but it started chipping after that. They have lasted the better part of a year, though.

Pray tell, do you need a NTI?? *If*, the invisilign *retainers* are *not* contructed to overcorrect previous rotations, maybe the will work. An active aligner will be applying pressure opposite the direction of anticipated movement - thus tight contact where pressure is applied and a distorted no contact for anticipated movement. In my mind that would be the equivalent of a bleaching solution resevoir. I have not treated a case with invisilign but have taken their course. carabelli I used a calculus-removing solution in my ultrasonic > cleaner--don't know if that was the problem, but it started chipping after > that.

To the previous comment if you place the gel in an active aligner there may not be any space for the gel next to the tooth as well. So only use the aligner that has been worn for 2-3 weeks for bleaching or wait for the retainer and do it at the end. Most aligners cover the entire surface but sometimes the computer overtrims and it is short. > >>>>>I got a free bleaching kit with my invilalign treatment and was > >>>> [quoted text clipped - 76 lines] > > > > Steve yes you can > I got a free bleaching kit with my invilalign treatment and was wondering > if I can use my aligner instead of the trays that came with the bleaching > kit. > > Thanks. |
