Invisalign

Invisalign is a method of straightening crooked teeth without visible braces.

If I use Invasalign to correct my lower teeth, will that affect my upper teeth, which are fairly straight?

Invisalign is a terrific option to correct lower teeth crowding or spacing. AWe may need to introduce Invisalign for the upper arch if we are correcting the lower teeth. However, this is not always the case. Many times we have corrected one arch with Invisalign and left the other arch (upper arch) alone. It's all on a case by case basis.

In many cases, in order to move teeth on the bottom you will also have to move some teeth on top. Even though you said your upper teeth are fairly straight, they probably could benefit from Invisalign as well.

Upper and lower teeth come together in a specific way. If braces are placed, they should be placed on upper and lower teeth.

No, not if done correctly. I would recommend aligners or the Invisalign trays on top and bottom. For me to treat top and bottom is the same fee as treating just one or the other. I do this to make sure your bite will be perfect in the end.

When you say your upper teeth are "fairly straight" that is hard to interpret. Most people with crowded lower teeth do have some alignment issues with their upper teeth. It usually does not change the cost much to treat both arches. However, if only your lower teeth need to be straightened, that can be done without affecting the uppers. I hope that helps. Good luck!

Not always. It depends of the amount of correction to your lower teeth and the bite relationship with the upper teeth. The key is to ensure that the movement to the lower teeth, no matter how big or small, does not cause a functional interference with the upper teeth in order for the upper teeth not to be affected.

Invisalign is typically done on both upper and lower teeth(arches) simultaneously. It is fairly common to have one arch straighter than the other. In those cases, you still wear the upper and lower aligners the same amount of time. However, the arch that needs less or minimal movements will have "passive"(non-moving) aligners versus "active" aligners for the arch that requires more movement. It is best to wear both aligners at the same time, even when you are no longer requiring movement on a particular arch, so that your bite is not changed or effected from just wearing one aligner. While there are certain cases where only one arch is indicated, that is not typical.

whenever you correct the alignment of an arch, ie lower, you should do the upper in conjucntion. the reason is more bite issues than the alignment. the upper and lowers need to match up properly.

By moving teeth on the lower, your bite may be affected and thus your upper teeth may need to be moved so you can bite correctly and comfortably. Les Latner, DDS drles@ucla.edu

In my office, Invisalign is used to address the patient's chief complaint. If your only issue is your lower teeth, you may not need to move your top teeth. However, often your top teeth are the "fence" that holds the lower teeth and they may need to move to acommodate the change of position that the lower teeth need. Peace of mind comes from the fact that the fee charged to move your teeth, whether top or bottom, is the same. SO, if your bottom teeth must be moved, your Invisalign dentist can also move and improve your top teeth for no extra charge. My experience is that the end result will be an improvement with the top teeth that are "fairly straight" already. Why not have "perfectly straight" top teeth instead of just "fairly straight" top teeth. (Especially if it's at no extra charge?)
