When I started this blog, I told myself that I wouldn't be one of "those" Invisalign bloggers that stopped blogging. Alas, it's been nearly a year since my last entry. Eventually, in treatment, you just hit a groove. Everything becomes automatic and not much happens. I got caught up in the somewhat pleasant monotony of weekly tray changes that changed briefly to every-6-days-tray-changes.
Here is the final result:
After 38 trays in my initial treatment plan - or, basically a year's worth of trays with my orthodontist's usual every-10-days-tray-changes - my orthodontist ordered a mid-course correction. I think the plan was to get me that far and see what else needed done. After simmering in that 38th tray for about 7 weeks, the new aligners - which included 15 1/2 active trays - came in. (Bag 16 of the mid-course correction included a passive aligner.) They popped off all the old attachments and put new ones on as I shifted from 38/38 to 1/16.
My sense is that the early part of treatment was focused on getting the arches established and some basic alignment. The portion was rotating a few lower teeth (not all cooperated due to anatomical issues) and fine-tuning the bite. For the last part of treatment, the majority of the attachments/engagers were on my lower arch. This included some long bar-shaped attachments on my lower right and left laterals.
