Clear aligners are the new way to straighten your teeth without braces. They are removable trays used to move teeth into position in the correct and proper alignment. As clear aligners are removable, the patient can take them out to eat, brush and floss their teeth, but is expected be worn throughout the day. Aligners are made of acrylic or clear plastic material, free of any sharp or hard materials that might irritate the mouth.

These clear plastic trays are placed over your teeth and adjusted by the dentist to help move them into alignment. What’s the good part?- They are less noticeable than traditional braces because they aren’t visible when you smile!

How do clear aligners actually work?

Unlike traditional braces, clear aligners don’t require metal brackets and wires. Instead, you’ll wear each tray that fits perfectly in the spaces between your teeth. Your treatment with aligners from start to end is monitored by your dentist with the help of images and X-rays of your teeth.

As soon as your dentist tightly fits the tray onto your teeth; these aligners apply force on the teeth to position them in their correct place. Advanced computer softwares are used to create a plan for repositioning your teeth from their existing locations into the ideal alignment possible. Your aligners are then changed every two weeks as the force takes the teeth closer to their planned position.

Aligners typically take between 9-18 months for results to be seen depending on the severity of your case. During this time you’ll continue to visit your dentist every 2-4 weeks or so for adjustments to maintain proper teeth positioning and monitoring throughout the treatment time frame.

What are clear aligners made of?

Clear aligners are made of polyurethane, which is hard, acrylic, and thermoplastic and are completely BPA-free. This material is resistant to heat and impact, so it can withstand the pressure of your teeth as they move into their new positions. Clear aligners do not require bonding to the teeth, unlike braces, and can be completely removed on your will.

How are they fabricated?

Clear aligners are fabricated in specialized labs but the prerequisites are recorded by your dentist. They involve your dentist and lab technician. With the following mentioned steps, you can get a clear aligner from your dentist, only if you are the right candidate for it.

  • To begin, your dentist takes a correct impression of the teeth to create a mold and develop an appropriate clear aligner that fits well in the mouth, Or get a digital scan and a 3D imaging of your mouth.
  • Your dentist clicks photos of your teeth and mouth. Collecting records is critical for improving the aligners during the manufacturing process and determining that the clear aligners are created properly.
  • In the next step, your dentist takes X-rays to get a complete overview of the health of your teeth to create the right clear aligners.
  • The impressions(or scans) are sent to specialized labs for the production of 3D models. Clear aligners are then fabricated on these 3D models using a thermoplastic resin. This way your dentist delivers the appropriate clear aligner to you.
  • You might have come across the name, “Invisalign “while scrolling on google or Facebook. This brand of clear aligners uses advanced computer software to create appropriate clear aligners. Invisalign treatments prove to have better results and only certified Invisalign practitioners are permitted to deliver aligner treatments. Here, the desired movement of teeth is planned before the treatment, and accordingly, your clear aligner trays are fabricated and custom made for you.

Quality check of aligners

When it comes to your face, you tend to use products that are certified by quality check. Similarly, your teeth also need quality products rather than your DIY’s. A final quality check is performed to assure that all margins, borders, thicknesses, numbering, and arch shapes of your aligners are correct.

Quality check of the aligners do depend on the brands. Properly fabricated trays fit tightly on the teeth; however, too tight aligners can result in pain. In contrast, if the trays are poor fitting, they become loose and may interfere while chewing and swallowing and may not show results. Also, there might be some gap or space present between your teeth and the aligner which indicates inappropriate fit of the aligner during fabrication.
