New name for the blog

Quick note: We’re changing the name of the blog from Clarity to Clearly.

The address will stay the same: blog.clearcorrect.com.

ClearCorrect core values

When we started ClearCorrect, there were just a handful of us.  We knew who we wanted to be and what we wanted to stand for.  It was simple. 

As we’ve grown, maintaining that sense of identity has become more and more challenging.  New employees, new opportunities, even new customers have all brought their own ideas and their own values to the table.  It’s gotten complicated.

Complicated isn’t good for anyone, so we’re simplifying things again.

We recently took pen to paper and defined the core values that make us who we are, the values we believed in when we started the company.  There are nine of them.  We haven’t always exemplified them, but now that we’ve defined them, all of us here at ClearCorrect—and there are a lot of us here these days—can embrace them with the same passion and commitment we had when it was just a few of us.

To celebrate this milestone, we’ll be rolling out our newly defined core values, one value at a time.  Every week or so, we’ll post the value itself and a slew of other posts related to the value, including some behind-the-scenes looks at exactly how we’re injecting that value into everything we do.

We’re kicking it off next week with the first of the nine, so be sure to check back then.  We've got some good stuff planned...

ClearCorrect countersues Align: 10 patents, 408 claims, all invalid

Yesterday, we filed our response to Align Technology’s patent infringement suit. In our response, we’re countersuing Align and asking the Court to declare all 408 claims in 10 of their patents invalid.

We’re posting the entirety of the 246-page response here, along with the text of Align’s original suit against us.

You’ll find in the response, among other things, much of the evidence raised in Align’s previous patent case against Ormco, which resulted in a federal court ruling that 11 of Align’s patent claims were invalid.

Tech tip: Why are the distal edges of the aligner missing sometimes?

Question:

Sometimes I've noticed that the distal half of one of the furthest posterior teeth is missing from an aligner. Why is that?

Answer:

Sometimes we receive impressions that don't have enough detail to accurately model the distal edges of the posterior teeth. Distortion is much more prevalent in this area, because it can be difficult to make sure that the impression material completely covers the teeth in the back of the mouth.

Of course, we always prefer to receive complete, accurate impressions. But we don't want to inconvenience our providers unnecessarily either.

In some cases, we'll make an exception and process the case even though the distal surfaces of the posterior teeth are incomplete in our model. The aligners still have plenty of surface area to grip the teeth. We just trim off the potentially inaccurate area so that the case can progress without delay.

If you want to make sure that your patient's aligners fully cover the distal surfaces of all the teeth, just double-check your impressions to make sure that they're not distorted in that area, and you should be fine.

Tech tip: Why aren't the posterior teeth in occlusion?

Question:

As my patient’s treatment nears its end, I’m noticing that the upper & lower anterior teeth are touching when the patient bites down, but the posterior teeth are not in occlusion. What’s going on?

Answer:

There are many possible causes of this situation. This phenomenon is fairly common with clear aligners, and it’s usually temporary. It can be caused by the “hinging” action of the jaw.

Imagine placing a 1 mm sheet of flat plastic over the occlusal & incisal surfaces of the lower teeth. As the jaw closes, the posterior teeth will contact first. The patient would have to bite down firmly to get the anterior teeth to touch completely.

The same thing can happen when the teeth are covered by clear aligners. When the patient first starts wearing them, the posterior teeth are the first to contact. After wearing the aligners for a while, the teeth adjust to compensate, and before long, the patient can bite evenly with the aligners on.

The posterior teeth will usually intrude slightly to make room for the aligner, as the patient clinches his or her jaw throughout the day. Once the teeth have adjusted to the aligners, if the patient removes the aligners and bites down, the anterior teeth will make contact first and the posterior teeth probably won't quite touch.

This is not typically a big concern, however, because the posterior teeth will usually super-erupt back into normal occlusion as soon as they get a chance. After the patient has worn the final retainer for 3-6 months and the teeth are stable, the patient can switch to wearing the retainer on alternate days to give the posterior teeth freedom to move back into their normal position. Another option is to prescribe a Hawley retainer which won't interfere with occlusion, allowing the posterior teeth to super-erupt freely.

Tech tip: 4 ways to correct crowding

Question:

Which techniques should I prescribe to treat crowding?

Answer:

The simplest option is to check “only if needed” and allow our dental technicians to offer their recommendations.

If you have specific preferences for a patient's treatment, though, please let us know. At ClearCorrect, doctors are in charge. We will customize the clear aligners to carry out whatever treatment you prescribe to the best of our ability. If you don't see an option on the form, feel free to provide special instructions in the “other instructions” section.;

For patients with severe crowding, it's usually best to use a combination of techniques. For instance, proclination and expansion are more predictable together than either technique alone.

If the crowding is not too severe, however, you may be able to achieve your goals with just one of the four options (procline, expand, distalize, or IPR).

Here are the four main techniques, and when we recommend using each one:

Procline

Patient with line drawn from nose to chin
A good candidate for proclination

Proclining teeth is a useful way to give a patient fuller lips or a fuller side profile. This is recommended for older patients whose lips are a little “droopy.” This can also be desirable for people who have a flat profile.

To check if a patient needs to be proclined, draw a line from the tip of the nose to the tip of the chin on a non-smiling profile picture. In an ideal profile, the upper lip should almost touch the line and the lower lip should overlap it slightly.

If both lips are well behind the line, the patient might benefit from proclination. If both lips are well past the line, lingualizing the teeth might improve the patient's profile. (Lingualization isn't one of the standard options, but you can request it in the “other instructions” section.)

Expand

A nice wide smile

Expansion is the most common method we use to create space. It should be used when there is visible space between the posterior teeth and the cheeks when the patient smiles. A wider smile that shows more teeth can help your patients “light up the room.” Think Julia Roberts or Anne Hathaway.

Distalize

We often recommend distalizing the anterior teeth and/or premolars 1-3 mm if you want to achieve a Class I bite and improve the patient's chewing function. We don't recommend distalizing molars; they're very difficult to translate. Distalizing and mesializing less than 4 mm per quadrant keeps the movements more predictable and reduces the chance of interference with other teeth. Of course, if you want to try for more than 4 mm, you can always request that in the “other instructions” section.

IPR

We like to avoid IPR (interproximal reduction) whenever possible. However, IPR is sometimes necessary to create space for very crowded teeth to move. IPR can also be used to treat a case quickly by keeping the teeth in their current positions and just rotating them into alignment.

We usually recommend IPR when we are aligning both arches and we need to reduce the width of the teeth on one arch to get proper overjet. In this situation, IPR is usually only needed on one arch.

We can also use IPR to put premolars or canines into a Class I relationship, or to correct a midline misalignment.

As providers treat more patients, they usually get a feel for which techniques work best for them. If you have any comments, or preferred techniques and tips, please share them in the comments.

The free market

Seth Godin on the free market:

There's no question that an unfettered authoritarian corporate regime is more efficient and effective—in the short run. In the long run, though, the free market triumphs, as long as it isn't destroyed by those that get to play first.

The free market is a great idea, which is why we need to be careful when market incumbents lobby to make it un-free.

Amen.

ClearCorrect introduces Compliance Enforcers™

HOUSTON, TX—Clear aligner therapy has straightened the teeth of thousands of patients, easily and invisibly. The primary factor limiting successful treatment has always been patient compliance. If aligners aren't worn for at least 22 hours per day, the osteoclastic activity which reshapes the gums stops, and the teeth won't move as intended.

To combat this issue, ClearCorrect has always offered doctors a popular feature known as Compliance Checkpoints™. By checking whether certain teeth are touching at various points during the treatment, dentists can determine whether or not patients have been wearing their aligners.

Now ClearCorrect is taking patient compliance management to the next level with an exciting new aligner feature, available exclusively from ClearCorrect: Compliance Enforcers™.

Compliance Enforcers™ are tiny RFID-enabled microchips embedded within each clear aligner. Each microchip is equipped with an array of sensors designed to detect temperature, ambient light, and certain enzymes in the patient's saliva. These sensors enable the aligner to detect whether it's in the patient's mouth, in an aligner case, or under the passenger seat of a 1983 Subaru BRAT.

If the aligner detects that it has been outside of the mouth for over one hour in any 24-hour period, it begins to emit a periodic warning tone, which increases in volume and frequency as the two-hour mark approaches. At two hours, the aligner enters GuilTrip™ mode. A tiny speaker embedded in the chip plays a prerecorded lecture from the patient's dentist about the importance of aligner maintenance, followed by the sound of a mother crying because her crooked-toothed child will never find a spouse.

If the aligner is not reinserted into the mouth within three hours, it activates its unique Active Recovery™ feature. The aligner transmits a signal to a transponder chip installed in one of the patient's fillings. Using an advanced nanocomposite material to generate electricity from the patient's saliva, the transponder charges the other fillings in the mouth with a powerful electromagnetic field. The magnetic intensity is gradually increased, until it is strong enough to attract the Compliance Enforcer™ in the patient's aligner.

Drawn by the magnetic force, the aligner will then slide out of its hiding place and up the patient's body, attempting to reinsert itself in the patient's mouth. If all of that sounds unsanitary, don't worry. Compliance Enforcers™ are equipped with micro-nozzles which spray a concentrated antimicrobial foam onto the aligner when it begins to enter the proximity of the patient's face.

Please note that other metal objects may also be attracted by the extremely powerful electromagnetic force, so we recommend that all patients using Compliance Enforcers™ stay away from knives, metal buttons, zippers, keys, jewelry, and electronic devices during their treatment.

Compliance Enforcers™ are available as an optional upgrade to any ClearCorrect case starting April 1, 2011. The first 200 doctors to sign up for Compliance Enforcers™ will receive a special discounted upgrade price of $750,000 per aligner. Just call (888) 331-3323 and mention promo code "MICRONOZZLE."
