Today, for many of us, adults make up a
significant portion of our patient base. Many
of these adults have had treatment before and
remember their experience as painful, cumbersome
and time consuming. If your practice is
anything like mine, adult patients are often
looking for faster treatment, fewer appointments
and an aesthetic option that is far more
advanced than what they remember from their
childhood. Our adult patients are living busy
lives—with families to care for, full-time jobs
and laundry lists of to-do items—but, more
and more, health and beauty are becoming
high priorities.
This particular case is one of my favorites
because I was treating the patient’s son when
she asked if I’d be willing to look at her teeth,
smile and bite. She had seen what self-ligating
brackets did for her children—who I treated
with the Damon System—and she was eager to have a broader, full smile. She thought
aligner treatment was the best choice for her—
discreet for her work and social life and easy to
manage. What she didn’t realize was aligners
would eliminate her crowding, but wouldn’t
satisfy her desire to have a full smile like her
children’s. She was ecstatic when I told her we
had a Damon System treatment option with
clear brackets.
As aligner treatment gains popularity, this is
a common situation we all face. The following
outlines how I went about treating this case in
35 weeks with clear self-ligating brackets, resulting
in a happy patient with a beautiful smile.
Case Presentation
Class I (end-to-end Class II molar on right),
female patient, 38 years old, came inquiring
about clear aligner treatment. She had orthodontic
treatment by another clinician years before. I
had treated both of her children with the Damon
System and she had been pleased with the results.
Given that her chief concerns were the crowding
in her lower arch and the widening of her smile,
it was clear to me that aligner treatment wasn’t
her best option. I talked candidly with her about
how passive self-ligation would offer her the
results she wanted and could satisfy her need for
an aesthetic option with Damon Clear.
Diagnosis
- Mildly convex profile with a mildly convex
nasolabial angle. Slight lip strain
when lips were at rest with lower midline
shifted to the right.
- Slight gingival display in the maxilla, narrow
arches with 3 to 4mm of crowding in
the lower arch and 1 to 2mm of crowding
in the upper arch. Consonant smile arc.
- Aesthetically-shaped teeth in both arches
and excellent hygiene. Inconsistent gingival
architecture in the lower anteriors and
upper R3.
- Desire for discrete treatment option.
Treatment Objectives and Plan
Treat non-extraction, eliminating the
crowding by widening the arches using the
Damon Clear brackets U3-3 and Damon Q
elsewhere. Employ variable torque to foster the
proper inclinations in the anterior teeth and
maintain the smile arc.
Treatment Sequence
Bonding
U/L: Direct-bonded 7-7, engaging .014
round Damon Optimal Force Copper Ni-Ti1
archwires from 6-6 upper and 5-5 lower.
U: Placed a stop between U/L 1s.
1.5 Months — First Visit
U: Transitioned to a .014 x .025 CuNi-Ti
archwire. Ligature-tied U2-2. Added a stop MD
to UL1.
L: Transitioned to a .018 round CuNi-Ti
archwire. Added stop between lower 1s.
U/L: Started Quail, 3/16”, 2oz., Shorty CL
II elastics (right side only L6 to U4, full-time),
maintaining them throughout treatment.
2.5 Months — Second Visit
U: Transitioned to a .018 x .025 CuNi-Ti
archwire. Maintained ligature ties U2-2. Stops
were placed M-D to UL1 keeping 1mm of space
on either side of the bracket with the stops.
L: Transitioned to a .014 x .025 CuNi-Ti archwire.
Ligature-tied L3-3, maintaining it throughout
treatment. One stop placed between the lower 1s.
U/L: Maintained Shorty CL II right elastics.
3.5 Months — Third Visit
U: Repositioned the UR3 and dropped the
wire size to a .014 x .025 CuNi-Ti archwire.
Maintained ligature ties U2-2 and moved stops
mesial and distal to UR1.
L: Maintained the .014 x .025 CuNi-Ti
archwire and ligature ties L3-3.
U/L: Maintained Shorty CL II right elastics.
4.5 Months — Fourth Visit
U: Transitioned to a .018 x .025 CuNi-Ti
archwire and maintained ligature ties U2-2.
L: Maintained the .014 x .025 CuNi-Ti
archwire and ligature ties L3-3.
U/L: Maintained Shorty CL II Right elastics.
5.5 Months — Fifth Visit
U: Maintained the .018 x .025 CuNi-Ti
archwire. Ligature-tied U3-3.
L: Maintained the .014 x .025 CuNi-Ti
archwire and ligature ties L3-3.
U/L: Took interim panograph and repositioned
UR4, LR1 and LR3. The repositioning
was minor and did not require wire dimension
reduction.
U/L: full CL II right with parrot 5/16 2oz
elastics.
6.5 Months — Sixth Visit
U: Transitioned to a .019 x .025 TMA archwire,
adding 15° of buccal crown torque to the
UL3, maintaining ligature ties U3-3.
L: Transitioned to a .017 x .025 TMA archwire
and put a step-up bend in the LR4.
Maintained ligature ties L3-3.
U/L: Class II right parrot but transitioned
to nighttime only.
7.25 Months — Seventh Visit
U: Maintained the .019 x .025 TMA archwire,
putting a step-down bend UL1.
Maintained ligature ties U3-3.
L: Maintained the .017 x .025 TMA archwire
and ligature ties L3-3.
U/L: Maintained CL II right elastics at
night time.
7.75 Months — Final Visit, 35 weeks
U/L: Removed all appliances. Shaped and
polished the teeth. Took impressions for 1mm
Essix-formed clear overlay U/L retainers. Bonded
permanent retainer U2-2, just on the 2s, starting
at the UR2, shaping the wire tooth by tooth using
.016 x .022 Bond-a-Braid lingual retainer wire.
Bonded lower retainer, every tooth, L3-3 using a
.026 stainless steel wire, forming looping bends
on each end. The lower fixed retainer is to be
bonded for life. If the upper fixed retainer comes
loose after 18 months, we rebond it if the patient
originally had 3-4mm or more of spacing pretreatment.
Two weeks later, took final records and
delivered clear retainers.
Case Discussion
We achieved all treatment objectives and satisfied
the patient’s chief concerns. Interestingly,
widening the patient’s transverse arch width,
especially the U2-2, had the added benefit of
diminishing the excess upper gingival display. In
fact, she has proudly become a champion for our
practice and after treatment said, “I wanted to
look as good as my kids. I was worried about
looking like a teenager again or feeling like a
teenager, but I was glad to have Damon Clear
because I wasn’t as self-conscious about having
them on.”
In this case and others, I began experimenting
with using a Trilene fishing line rather than
ligature wire to keep space closed while transitioning
to a rectangular wire. It has proven to originally inquired about clear aligner treatment,
the fee would have been substantially more and
would not have allowed us to reach her objectives.
While clear aligner treatment can satisfy
the goals of certain adult cases, aesthetic fixed
appliances allow us to achieve outstanding
results due to the added control and ability to
continually adjust treatment mechanics to fit the
patient’s changing needs. Today, Damon Clear,
which is what I use in my practice, is available in
the uppers and lowers and the newly introduced
Damon Clear2 has two times the rotational control
for added precision and treatment efficiency.
What I Would Do Differently Today
I am a firm believer that there is always room
to grow and learn from every case. This case is no
exception. In looking back, the patient had a lateral
tongue thrust at the UR3, which plagued me
throughout treatment. If I were to treat the case
today, I would place lingual tongue reminders in
the LR/UR3 that would likely have resulted in a
more satisfactory Class I right cuspid relationship.
I encourage all clinicians to strive for perfection,
but take time to critically review each case to honestly
assess what you’d do differently given the
opportunity—often it’s the best way to learn.
