Invisalign Trays_Mid Course Correction. Well big day in my Invisalign treatment plan. I had requested a mid course correction as one upper molar has not been moving down and out as planned leaving a big gap between the tooth and the tray, and I knew my dentist had purchased one of the new 3D scanners so I thought that this was an ideal opportunity to review the whole plan. So on Friday I had the new gadget scan my teeth. It is a small hand held device that is run around your teeth, back and forth, back and forth until it builds up a digital scan. It is totally painless and much less stressful that the hideous goop trays that have to be jammed in your mouth and then wrenched off.  He pushed again his preference to change the plan and have no IPR at all, and I reiterated my concern about changing a plan so much at this point with me not knowing what it would look like or how much it would cost. After me nearing tears at the thought of me being forced to take this new direction, he suddenly suggested an option of me seeing the new Clincheck model with no IPR but agreeing to change it back nearer the old plan if I did not like the look of it. So this is what we are now doing. This means I only have to wear trays no 30 at night whilst I wait for the new plan and the new trays – so freedom!!! No trays in the day – AND even better he took off the two attachments that I hate the most, so I am having a little Invisalign holiday right now. I will report back when I see the new plan – very exciting.
