Overview

Premier Aligner

Engineered for precision, comfort and esthetics, ClearCorrect® aligners are the ultimate orthodontic tool for your practice. Born from decades of material science, research and innovation, our aligners combine our proprietary ClearQuartz® tri-layer material, performance trimline, and scientifically-proven clinical features to help you achieve your orthodontic goals.

ClearQuartz Tri-layer Material

ClearQuartz is a tri-layer material that provides greater orthodontic control by combining two layers of resilient polymers with an elastomeric inner layer, resulting in gentle, consistent application of force.

ClearQuartz retains 10x more of its initial force than many competitors*, retains its shape throughout the wear time of the aligner**, and has proven durability, demonstrating 4x more tear resistance than single layer polymers***.

Features

There are a lot of valuable features associated with ClearQuartz, but here are some of the main features to be aware of:

The outer layers provide:

• Toughness to help reduce wear
• Minimized staining
• Improved tooth grip

The inner layer provides:

• Better elasticity and reduced stiffness
• More predictable force application due to the enhanced elasticity
• Consistent and continual force application

How does it work?

3-dimensional engineered properties: forces applied in any direction receive the rebound response.

The elastic layer improves translation and rotation

What does the 3-layer structure do?

Some benefits of the 3-layer structure are:

• The elastic middle-layer enhances tooth-moving force and comfort because it's able to recover its form.
• The material is more durable because the elastic layer absorbs excess forces and reduces crack or tear propagation.
• This elasticity provides more comfort to the patient.

Multi-layer vs. Single-layer Material

Combining the properties of both flexible and rigid resins in a multi-layered film allows for greater tear resistance, lower initial force, more consistent and longer sustained force, and a more precise fit compared to the properties of other resins used in other aligners (e.g., polyethylene terephthalate)*.

The ClearCorrect Trimline

ClearCorrect’s performance trimline, scientifically proven clinical features, and custom manufacturing technology and processes result in an aligner that delivers greater control and consistent force application to achieve complex movements more predictably.

ClearCorrect's default trimline is a smooth, unscalloped, high and flat trimline that extends between 1 and 2 mm above the gingival margin. With the high and flat trimline, ClearCorrect aligners have been clinically proven to optimize force transmission for more accurate tooth movement and enhanced root control*.

Also available is the low and flat trimline that extends between 0 and 1 mm above the gingival margin. The low and flat trimline is available for use with patients that have specific clinical conditions where the high and flat trimline could impinge on the patient's dental anatomy (such as, low frenum, extreme crowding, gum recession and abfraction or implants and underneath bridges).

The effect of the trimline design of orthodontic aligners on force transmission was evaluated in a 2022 publication. The study concluded that the forces transmitted to the middle and cervical areas of the tooth with the high and flat trimline, were significantly higher and closer to the center of resistance, potentially improving control of bodily movement.

The low and flat trimline design, still transmitting forces to the middle and cervical areas of the tooth, higher and closer to the center of resistance as compared to the scalloped trimline design.

The scalloped trimline design was shown to be more flexible, reducing the amount of force applied to the tooth near the gingival area, required for a controlled tooth movement.

In addition, it has also been proven that aligners with a high and flat trimline are over 2.5x more retentive than scalloped aligners, which reduces the need for retentive engagers**. In a 2012 study, doctors from the University of Nevada compared the retentive strength of three trimming techniques:

A) a scalloped margin,

B) a straight cut at the gingival zenith, and

C) a straight cut at 2 mm above the gingival zenith.

The difference between the techniques was remarkable. For clear aligners without engagers, the straight cut 2 mm from the gingival margin was about twice as retentive as the scalloped cut. For clear aligners with engagers, the straight cut 2 mm from the margins was over four times as retentive as the scalloped cut. 

In summary, fewer attachments mean better esthetics, less visibility, which means happier patients.

Lastly, ClearCorrect’s custom manufacturing process improves tooth surface contact for optimized force distribution and accurate tooth movement***. 

How to request a low and flat trimline

To request a trimline other than the default high and flat trimline (the low and flat trimline), the request will need to be made when creating an order in the prescription form on Step 4 in the "Additional Instructions" section. Simple add the request for the low and flat trimline and then complete the rest of the order.

ClearCorrect Aligner Customization Features

ClearCorrect aligners are customizable to suit your patients' needs. ClearCorrect gives you additional ways to tailor your patient's treatment precisely to their needs: from customizable engagers to bite ramps, to cutouts for elastics, to pontics, bars and guides, clinicians can incorporate any number of treatment strategies to address cases ranging from simple to complex.

	Cutouts for Elastics With cutouts for elastics ClearCorrect offers you more control to perform more complex movements. Confidently treat teens, Class II, and Class III malocclusions.  Select a double vertical slit of half-moon button cutout Prescribe them in the Doctor Portal and approve them in ClearPilot Receive your aligners with pre-made cutouts for your patient to start wearing according to your treatment plan
	Engagers Engager sizes are available in 2, 3, and 4mm. Decide what size and orientation are best for your case.
	Anterior Bite Ramps Anterior bite ramps are available in 3- and 5-mm depths and are manufactured ready-to-wear according to your patient's unique treatment plan. Confidently treat deep bites and crossbites.
	Posterior Bite Ramps Posterior bite ramps are available for lower first and second molars and/or upper first and second molars. Posterior bite ramps on the second molars will be a height of 1.5 mm and first molars or pre-molars will be 2.0 mm. Manufactured ready-to-wear according to your patient's unique treatment plan so you can confidently treat crossbites and open bites.
	Pontics and Bars Tooth shaped pontics or bars are included in treatment when spacing is >3mm. This request may also be made at any step during the treatment and resized as spacing opens or closes. Pontics provide an aesthetic solution for anterior spacing, while bars are frequently used for posterior spaces.
	Guides Guides act as space holders and aid erupting teeth. These guides may be requested as a tooth shape or a bubble shape. Resizing options are available and may be requested to start on any step during treatment.

The Patient Experience with ClearCorrect Aligners

The ClearCorrect aligner has been developed for patient satisfaction. The tri-layer design of our ClearQuartz material improves comfort without sacrificing durability, and when combined with our clinical protocols, patients may achieve faster results.

	ClearQuartz's innovative flexible inner layer applies 1/3 less initial force, enhancing patient comfort during aligner treatment*
	ClearCorrect aligners have been proven to be more stain-resistant than the leading aligner brand**
	ClearCorrect's digital manufacturing technology enhances the trimline design for a custom and more comfortable fit

The stain-resistance properties of ClearCorrect were tested against the leading aligner brand. In a simulated test, where aligners were immersed in 4 different staining agents, ClearCorrect demonstrated to be more stain resistant, as shown in the results below**.
