Are Lingual braces as effective as Invisalign for shifting moderately crooked lower teeth?

Depending on the experience of the clinician and the situation presented, one method may work better than the other. It would be best to have a consultation with the office that advertises iBraces and see what they suggest.
Everything works, but some work quicker or more easily than others. You might find that iBraces would work very well for you.

Not only are lingual braces just as effective as Invisalign, they actually give your orthodontist more control over the outcome of your final result than Invisalign. I use both and each has its own advantages and disadvantages. Invisalign doesn't have wires and brackets, but some patients just don't like having their teeth encased in plastic 24/7. There is also the issue of compliance with Invisalign. If you don't wear them, they don't work at all. Lingual braces, combined with Suresmile CAD/CAM technology, gives your orthodontist complete control over your case from beginning to end. Lingual braces allow more complex movements and there are no compliance issues. I agree with the other doctor in this thread that recommended that you see an orthdontist who uses both. Then you'll get an unbiased opinion about what is best for your individual situation. Good luck!

In my experience, Adults do not want to be uncomfortable especially while wearing braces. Its hard enough for them to let alone acknowlege that they need braces in the first place. There is no doubt that both iBraces (lingual braces) and Invisalign have their limitations. No appliance system is perfect. With all things being equal, anything attached to the inside surface of your teeth is downright uncomfortable. In most cases, adults will choose speed and comfort over small advantages in appliance capabilities. In terms of comfort, Invisalign wins out hands down.
