In general, what makes a passive self-ligating
bracket superior to a twin bracket?
We find the two biggest advantages to be time and consistency-less
time during each appointment, patients don't have to
come in as much and consistent staff training. There are a lot of
variables with chairside assistants, such as which hand one holds a
ligating instrument in, or how tight one ligates over. With a quality
PSL door, it's quick and easy: The door opens and it closes. With
fewer variables, we find training to be more effective.
Tell readers about the unique characteristics
of your PSL bracket.
We left no stone unturned with the design, but the two fan
favorites are the 0.020-by-0.026-inch slot and Norris door technology.
By precisely reducing the width and depth of the slot to 0.020 by
0.026 inches, torque can be picked up earlier and bracket slop is
almost eliminated during finishing with a 0.019-by-0.025-inch
wire. The Norris door has a self-closing/self-opening mechanism
that has proven to not fatigue throughout treatment in thousands
of cases.
For the doctors who tried passive self-ligating
braces in the past and were not happy, why
should they view your product as substantially
different?
Five years ago, we worked with a large group of long-time PSL
beta testers who'd been frustrated by the lack of control with their
previous PSL systems. This is how the Norris system was created.
By tightening the interplay between a 0.019-by-0.025-inch finishing

wire and a 0.020-by-0.026-inch slot, the second- and third-order
control have dramatically improved the rotational and torque slop
issues commonly seen in previous systems.
Inaccuracy and lack of control in finishing
details has long been a notorious problem
in the PSL world. How is your product
different?
Traditional PSL bracket systems shined during early treatment
but suffered once the finishing stages began, owing to a perfect
storm of undersized wires and oversized slots. The industry's dirty
little secret is that bracket slot sizes of " 0.022 by 0.028 inches "
are often 0.024 by 0.03 inches. By tightening the tolerances of
the Norris 20/26 System and exceeding standard manufacturing
specs, we're able to achieve an intimate fit between the finishing
wire and the slot, resulting in unprecedented control in finishing.
Today, there are quality twin brackets with
accurate and consistent slot dimensions for
around $1 or even less. Tell us in practical
terms why the ROI with your premium bracket
" pencils out. "
It's all about time: Appointments take less time with a quality
PSL system, and patients can be treated with fewer appointments
because of earlier torque command and rotational control during
finishing. Saving even one appointment easily pays for the difference
in bracket cost, and our research shows more. However, many
orthodontists are surprised how economical the Norris price is
for such a high-quality product. n
