You can call this the St. Louis of tech tips, because it's all about the single arch.
Three announcements today:
1. Passive aligners now included for completed single arches
Sometimes, one arch completes its movements before the other arch. In that situation, we used to ship the final retainer for that arch, and send just one aligner with the remaining steps.
Now, when one arch finishes, we'll include a fresh retainer (a.k.a. "passive aligner") for that arch with each subsequent step. If you submit a dual-arch case, you'll get two aligners in every bag for the entire case. So if you stopped getting aligners for one arch, and now you're getting them again, it's not a mistake, it's free retainers. Merry Christmas!
2. Single-arch impressions OK for Phase Zero revisions
As a general rule, we've usually required upper & lower impressions and a bite registration for just about anything.
But what if you get Phase Zero and one arch fits great, but the other arch has problems? We're changing our policy. Now, if you like, you can submit an impression just for the arch that needs correction. Happy Hanukkah!
3. Single-arch impressions OK for midcourse corrections
You can probably guess where this is going.
What if you're submitting a midcourse correction, and one arch fits fine, but the other needs work?
We'll still happily accept two impressions and a bite registration, but if you prefer, we'll also accept an impression just for the arch that's having problems. Happy New Year!
