Anyway, just a quick update. Everything is looking good. My dentist showed me how my teeth have moved on the screen- just to keep me motivated. Without looking at the screen, I have already noticed the difference in my lower teeth myself! I see it in the mirror everyday when I brush my teeth... and indeed, it keeps me happy, at least for the first 10 minutes in the morning!
The difference isn't so great on my upper teeth, however. So it's helpful seeing the difference on the screen with the dentist! Seeing is believing right?! :P My dentist did mention that there was one stubborn tooth which seemed a bit more difficult to be moved and that I might require further 1 or 2 refinement trays. =_=
Definition of a refinement aligner
Invisalign® also allows for refinement aligners, which can be added at the end of the scheduled treatment procedure, to finish off any tooth movement not fully expressed. This is usually needed if over-corrections are not accurately planned during the treatment-planning phase. It also happens because there is a slight flex in the aligner material that sometimes does not allow for full expression of the desired tooth movement. Refinement has to be elected prior to manufacture. No additional impressions are needed, but a refinement form outlining the desired extension tooth movements and photographs are submitted to Align Technology.
So this is the annoying tooth- you can see there is a slight gap between the bottom of the tooth and the bottom of the tray! That tooth is supposed to be pulled down a little bit more... but it doesn't seem to be moving as planned. Oh well, at least the dentist did say there wasn't anything to worry about... so I am not too concerned. If I need 1 or 2 refinement trays, so be it. As long as the end result is having straight teeth, 1 more month is not going to kill me.
Anyway, watch this space, I will be uploading 2 really short videos here! :)
