What are some good message boards about Invisalign?

The cosmetic treatments review site Real Self has a sub-forum dedicated to Invisalign discussions. Healthboards and ArchWired, a website for those with braces, also have numerous discussions on Invisalign and other brands using a similar system.

Invisalign is a brand of clear aligners, which is an alternative to metal braces, according to Wikipedia. A dentist takes a mold of the patient's teeth, and a computer analysis then suggests a series of intermediate positions between the current and desired positions of the teeth. A professional then creates an aligner in transparent plastic for each position, and the patient wears each aligner for about two weeks. Average treatment time is 13.5 weeks, and the system works best for moderate corrections.
