Phase 1 Complete; on to refinements

Finished the last of my 23 upper and lower aligners. Orthodontist says there are a couple of teeth he would like to move a bit more. He also said that it looks like some of the upper incisors needing to come down more are not likely to move much - that type of movement is generally tough for Invisalign, and with my veneers it makes it even more difficult. He said he will try, but not to expect much; that new veneers will make everything look great (though I am not looking forward to the expense of all new veneers).

Meanwhile, he ground off my attachments and took new impressions for refinements. He expect 5-10 aligners for round 2, followed by retainers which he will make in-office. They also took new photos. Will post when available.

The last aligners feel strange without attachments - there is no "click" to know they are properly placed, and they are much easier to remove. He told me to wear the aligners only at night until the refinements are in - he is hoping some of the teeth in the back will "settle in" - with Invisalign the aligner prevents full contact of the teeth, so they need time without aligners to get into final positions.

The FDA and Invisalign

The recent activity between the FDA and Align Technology is concerning. Seems the makers of Invisalign have been neglecting to report side effects reported to them by patients and dental professionals. This is an FDA requirement for makers of medical devices.

This was a concern of mine going in...I have sensitivities to many chemicals, and Invisalign aligners are essentially plastic gadgets you leave in your mouth nearly full time for a year or more. I also read that the aligners are sprayed with a disinfectant before leaving the factory; the disinfectant could also cause reactions.

What should we all be doing about it? First, keep an eye out for side effects like swelling, sore throats, itching lips or gums. Keep you orthodontist in the loop, and don't be afraid to report to the company or FDA. I also take the precaution of thoroughly cleaning fresh aligners before inserting them. This means soaking in Dentasoak (which I love [unpaid endorsement]) for 15 minutes, then brushing with a toothbrush and a little low abrasive toothpaste, then a good rinsing in warm water. Seems to take away the "plasticy" taste and odor of new aligners.
