12 Weeks with Controlled Arch
12 Week Controlled Arch Update
Before the current Controlled Arch phase of treatment shown in the images below, I wore the Anterior Growth Guidance Appliance (AGGA) for 44 weeks.
The photos below were taken on December 15, 2018, 12 weeks into the Controlled Arch phase of my treatment. Week 8 photos can be seen here.
Updates and Observations at Week 12:
Dr. Kundel has removed my upper FRLA (Controlled Arch) as part of his accelerated effort to correct my maxillary cant (the diagonal tilt of my upper teeth).
This cant can be seen in the smile photos below. It has existed for several months.
Dr. Kundel disagrees with the hypothesis put forth in my last video update that the cant was caused by AGGA growing my left side almost 1.5mm more than the right side.
He thinks my entire maxilla is tilted.
He thinks this is unrelated to asymmetries in AGGA growth.
So Dr. Kundel removed the upper FRLA at my last appointment on December 7 and placed a firm metal band inside of the brace brackets.
This firm band is supposed to correct the cant.
Because the upper FRLA is no longer in place, there is no elastic tension pulling the upper rear molars forward.
This is why there has not been much growth in the new gap forming as a result of the upper molars being dragged forward
Without an FRLA, trying to pull those molars forward will result in the front teeth being pulled back instead (aka AGGA progress relapsing).
One of the main purposes of the Controlled Arch is to prevent the front teeth from going backward while pulling the molars forward with braces.
Supposedly the FRLA/Controlled Arch also plays a role in creating lateral maxillary expansion (widening of the upper arch) but I do not feel like much of this has occurred.
The lower FRLA (Controlled Arch) was installed on November 21. See image below.
The reason it was not installed along with the upper FRLA back on September 21 is because none of the stock arch wires Dr. Kundel had fit my mandible, so a custom FRLA had to be ordered.
