Orchestrate 3D v. Invisalign; which is better?
Why is Orchestrate 3D a better Aligner
System than Invisalign?
Some 20 years ago, digital technology advanced to the point
that lasers could scan your teeth and create a digital image to be manipulated
by computer software and Invisalign was born.
A patient being scanned with a laser scanning wand; note the digital
image of the dental arch on the monitor.Scanners like this can capture an entire dentition in a matter of
Certainly the pioneer of the clear aligner process, today
Invisalign (Align Technologies) is not the only game in town (though they
certainly would have the pubic believe this and they have purchased other
start-ups to stomp out competition).In
fact there more than two dozen companies and labs now offering clear aligners
and more join the field every year due to lax standards and essentially no
The question for prospective patients today is which
system is the best for you and your family?
Set of Clear Aligners formed from 3D models following laser scan of teeth.
To answer this question, one must understand the process of traditional
Orthodontics a bit more in detail.
When you discuss braces, I bet you never ask “What brand of
bracket do you use?” to your Orthodontist.Why? Because you are paying for the Orthodontist
and his/her expertise, not the brand of material that is used.How the Orthodontist gets the job done is up
to them and their training/experience.Just like if you have a crown made, you don’t ask “What brand crown?” or
“which lab will you be using?”
As you would expect, there are many different brands of
every dental supply we use as Orthodontists; different slot sizes, different
metals, different wires, etc.Some may
even be better for one patient over another for whatever reason and based on
experience.A good Orthodontist would
never handicap themselves as disciples of only one technique or one system.
And a good Orthodontist bases treatment on their
understanding of bio-physics, not on the materials alone.If one system is incapable or less efficient of
movements needed, they will choose another system or appliance.For instance, forces are being generated
using some teeth as anchorage so that other teeth can be moved.Some movements require tipping, others
rotations or moments; opposing forces must be recognized and either countered
or harnessed.It becomes a very complex
system as every force will have an equal and opposite force.This is true whether we use aligners, braces
or simple rubber bands.
Newton’s 3rd Law
The old adage is that a good Orthodontist (using traditional
braces) can fix teeth with a paper-clip which might be over-simplified but points
out that it is the doctor, and not the material, that corrects the malocclusion
and restores the function and the overall smile.
traditional braces] it is the doctor, and not the material, that corrects the
malocclusion and restores the function and the overall smile.”
When aligner trays are used instead of traditional braces, the
ability of the doctor to make changes to aligners mid-treatment and throughout
the course of treatment is very important since all trays are pre-fabricated in
almost all systems including Invisalign; in other words when certain trays fail
to move a particular tooth or there is an unexpected force that opens the bite,
future trays will be unable to make the correction.The more failures along the way, the poorer
the correction and the higher risk of leaving new malocclusions such as
openbites, interferences, crossbites and incomplete uprighting of teeth.In MANY cases, poor aligner performance from
Invisalign introduces malocclusions
previously not present at the initiation of treatment (see my blogs listing
recent studies on Invisalign).
This is even more troubling when Invisalign “doctors” leave oversight
to relatively under-educated assistants.Invisalign would have you concentrate on their materials and technology
but they neglect to educate the public on the role of the doctor (or lack of)
as if the doctor has no role.In fact
they would prefer no doctor involvement which is why they have invested in
aligners being marketed direct through TV commercials and kiosks in some malls.In some sense there really is NO reason to go
to a doctor for such incomplete care.
But Invisalign cannot ignore biology.Treatment without considering bone
physiology, the inflammatory process or developmental processes is treatment in
the dark.Moving teeth though irregular bone
in a functioning, living system that undergoes modification and changes
throughout treatment (and thereafter depending on how we leave the bite or
occlusion) takes a complete knowledge of that system and an ability to make changes
along the way.This is absolutely
ignored by many who sell “aligner alignments”.
It is also clear in the literature (and confirmed regularly
from my own 22 years of experience) that the jaw shifts as the teeth are moved throughout
treatment (almost always in adults); some shifts will be predictable but some
can be a surprise.The relationship
between upper and lower teeth can and will change significantly from the start
to the end of treatment requiring modifications of the treatment plan along the
way (continuous re-scanning if aligners are used).Consider a perfectly good doorway after its
foundation settles or moves.After the
shift, the door is identical, the jamb is the same.But the door no longer opens.It doesn’t fit because of the shift.
Note the settled foundation and now off-set door.No damage was done to the door but it no
longer functions due to the shifting of the foundation.
The same thing happens to differing degrees when the jaw
shifts during orthodontic treatment and a good Orthodontist will identify the
shift, adjust his/her course of treatment and modify the force systems and even
appliances being used to counter the shift.Invisalign limits the Orthodontist’s ability to adjust for these
What is Orchestrate 3D?How is it better than Invisalign?
Orchestrate 3D is an aligner system used only by certified
Orthodontists; it uses clear aligner trays the same as Invisalign and the other
higher-end products but changes to the teeth (the angles and movements) can be
performed completely by the treating Orthodontist.Cases can also be reviewed by other certified
Orthodontists at the beginning of treatment to gain from experience of other
With Orchestrate 3D, teeth are scanned the same way as
Invisalign but the raw image (.stl file) is sent to the Orthodontist directly
and he/she makes all of the actual movements and attachments in-house on high
power proprietary software owned by the Orthodontist and not a 3rd
party.Then models based on those
changes can either be made in-house with a 3D printer or sent to a lab for
printing based on the Orthodontist’s changes made in the software.
Another great difference between Orchestrate 3D and other
aligner systems like Invisalign is that with Orchestrate 3D, the Orthodontist uses
the models he/she created to make the aligner trays in-house; that means he/she
can use different strength materials based on the movement of the
teeth/compliance/fit of the teeth.If
rotations are too great, more pliable material can be used.If there is a stubborn tooth, a thicker
material can be used just for that movement or a new tray can be fabricated until
the tooth moves.
Finally, a huge advantage that I like about Orchestrate3D is
that as the Orthodontist, I own the file start to finish; I don’t have to pay a
third party company every time new trays are made or when changes in the
dentition/jaw relationship warrant a new scan.For very Orthodontist, this makes more difficult cases less costly and
the Orthodontist more likely to re-scan as needed instead of just leaving some
teeth unmoved.I can limit myself to printing
5 to 6 trays in advance so that I can easily make digital changes for future
trays in more severely rotated cases including placement of buttons on stubborn
teeth mid-treatment.This prevents the
temptation of moving forward based on a previous jaw position or a previous
scan when surfaces of teeth may have been initially hidden from rotations.
In other words, Orchestrate3D is much closer to regular
braces than Invisalign when used by a competent and experienced
Orthodontist.Most importantly, this
assures you are paying more for the Orthodontist and not just for the material and
lab techs to move the teeth.
“Orchestrate3D … assures you are paying
more for the Orthodontist and not just for material and lab techs to move the
With other aligners like Invisalign, most of the time, you
are paying for a technician to scan your teeth (the laser actually does the
scanning), advertising for a corporate product independent of any doctor,
royalties on the software that interprets the data and builds a digital image
of your teeth (something a high school kid can do these days), and an unknown
and likely uneducated third-world Country “technician” to digitally re-set the teeth with a mouse
into what they think looks and fits good.Then to top it off, a relatively un-educated dental assistant approves
the digital bite with a yes/no, and sets of trays are fabricated somewhere (again,
usually in a third-world Country) and packaged in a clever container to present
to you (again many times by the assistants) when it arrives back via UPS.
You may ask (like I used to before speaking with so many
colleagues) why a Dentist or even a real Orthodontist would leave there
profession up to private companies, lab techs and third world technicians?The answer is simple and I will be direct: Profit and ease of treatment (for the doctor).The following are real responses I have
gotten from dentists and Orthodontists and consultants/sponsored speakers at
“Why refer to a specialist when I can just send it to a lab
like a crown?”
“Why go two to three years (after you are already a dentist)
to learn about Orthodontics when you can just send the patient to have a scan
and your completely done?”
“Why place braces and take the time to see the patient every
month and why worry about repairs and emergencies when they can give something
that can simply be removed if it hurts?”
“Why figure out the physics and continue to evaluate each
patient at each visit when you can receive all of the mail-order trays at one
time and just give them all out or 4 at a time?”
excellent care if the patient does not demand it?” (This was actually alluded
by the head of Orthodontics in a New York Dental School!)
If you think there are higher motives than these, you are mistaken.
So can Orchestrate3D clear aligners be
used with success?
The answer is yes in certain cases.The following are general guidelines for
proper Aligner Treatment:
Proper examination and records.No treatment should be planned without
first obtaining a standard set of orthodontic records including photos
(face, teeth and smile), a panograph X-ray and a side view or
Cephalometric X-Ray.There should
be an in-person examination of the teeth and jaw BY THE DOCTOR so that
function and joints may be assessed and the overall health of the gums and
teeth are evaluated.If there is
bone loss or any other concerns/disease, then further records/consultation
with other doctors may be needed.
Proper Case Selection. Aligners are able to make certain movements
on teeth but unable to move others; for instance a canine cannot be uprighted
by aligners and teeth cannot be pushed into the bone adequately with aligners.Also, some mal-occlusions are more due
to discrepancies in jaw size, shifting of the jaws or more severe
interferences; aligners are not able to correct significant overjet, deepbites
or openbites with any stability.
Realize and acknowledge that there is almost no
case that cannot be treated faster and to a better result with traditional
braces.Aligners are great only
because they are relatively un-noticeable.But aligners CANNOT move teeth as predictably, as far, as precise
or as fast as braces.If someone
tells you otherwise, they are misleading you and you should question their
motives.There is nothing wrong
with using aligners as long as you are informed and willing to accept the
results.Aligners will align front
teeth and give you a better smile but be
realistic in your expectations.
If aligners are prescribed
without an option of braces, ask if it is the best treatment.Ask if there are certain aspects that may
not treat as well as braces.If a
dentist or Orthodontist flat out tells you it is a bad idea, you should
heed that warning.I personally
won’t treat cases with aligners if they cannot make enough improvement in
the smile, if they will risk significant malocclusions, if they will lead
to certain relapse or if compliance is predictably going to be poor.It is malpractice to offer something that we know will do
harm.That is not to say
someone won’t sell you what you are asking for somewhere (usually down the
street in my case), but don’t expect less risks from the same products especially
from something like Invisalign that is made the same for everyone (less
Follow all instructions and DEMAND you see the doctor at every
visit.Ask questions as to the
progress and if something doesn’t feel correct, make sure you bring it up
with the Orthodontist before the end of treatment. You ae indeed paying for the doctor, not
the plastic or the assistant.
Finish your prescribed course of treatment.After speaking with dentists and
Orthodontists over the last 20 years it has become clear that a
significant portion of patients simply fade away and discontinue treatment
on their own, I would wager it is @25%.That is an amazing number but I assure readers that if they ask around
they will see this is not inaccurate or exaggerated.
Demand at least some occlusion on all back teeth at the end.There may be less of a correction but
the front teeth should look good and the back teeth should at least touch
after treatment.If not, YOU ARE
NOT DONE!Don’t allow any office to
dismiss you without contact on your back teeth.
Wear retainers.Aligners relapse more often (much of this is due to poor treatment
and/or poor case selection).Aligner cases should expect to wear nighttime retainers
What are potential problems with poor
First of all, you can damage the roots of teeth and leave a
bite that damages the edges of your teeth.Over time this can lead to chronic jaw pain, multiple restorations and
even loss of teeth.You can EASILY leave
teeth worse off than when you began even if they look straight.I repeat, EASILY.Pushing teeth outside of their natural arch
form will lead to recession (gums falling away from the teeth and exposing the
roots), relapse and/or sensitivity.
Will the dentist tell you if the treatment was a failure?Some will I know because I see patients
referred after failure of aligners, but many (especially those who are treating
without adequate knowledge or morals) will not and patients are left with
chronic problems and sometimes chronic pain that Orthodontists now won’t touch.If you question your correction and bite
after treatment, see another Orthodontist and ask for an evaluation; these are
generally free and can either give you peace of mind or inform you if there is
indeed a problem.
It is up to patients to ask the right questions, interview
prospective doctors and filter through the direct advertising that bombards the
public regularly in search of more dollars.Remember Orthodontics is about your smile but equally about your
function and dental health for the future.And remember what you are paying for and what questions to ask BEFORE
entering into treatment with anyone.
