For centuries, archived records show that individuals have had a fascination with straight teeth.

Clear Aligners Invisalign

But for as long as we can remember, metal brace-like devices have monopolized this market and been established as an orthodontic mainstay. 

Fortunately, The last decade has witnessed an overhaul of new dental appliances that guarantee a hassle-free treatment: invisible clear aligners or braces.

Invisible aligners offer a convenient and comfortable alternative to realigning your teeth.

Here’s everything you need to know about Invisalign.

What are dental clear braces?

Treatment with clear braces may involve an orthodontist or dentist but they also come in home-based systems.

In the latter, patients are responsible for taking scans of their teeth and sending them to a direct-to-consumer brand that then supplies the final products.

What are Invisalign Aligners?

Invisalign is a brand of clear plastic aligners that have been accredited for the popularization of this novel teeth-straightening model. Founded in 1997 by Align Technology, it uses patented SmartTrack thermoplastic aligner material to help transform smiles.

Invisalign like most clear aligners is made from medical-grade plastic that can realign teeth without the use of metal bracket-and-wire systems. These orthodontic aligners are also “less conspicuous” in nature, making them an ideal treatment option for young adults and teens.

According to the Invisalign website, more than 12.8 million people around the world have benefited from correcting their crooked smiles using Invisalign. 

How does Invisalign work to straighten teeth?

The Invisalign system is unique in how it works. Invisalign uses a series of tight-fitting custom-made mouthpieces that snugly fit over the upper and lower teeth.


On average, orthodontists may assign 18 to 30 trays depending on the individual’s case.

You may be perplexed by how the aligners of Invisalign work. This is how. 

It utilizes a sequence to custom-fit aligners, that help slowly move the teeth into proper position. They realign your teeth using constant and gentle forces and distributing them across all the teeth. 

The patient moves on to their new aligner set when the movement brought on by the current aligners is on track and satisfactory. At times, your doctor may also apply SmartForce attachments to your teeth which are small buttons that give aligners leverage to move easily.

With these braces, the patient experiences less discomfort due to the gradual forces applied by the device as compared to fixed metal appliances like braces. Experts report that the aligners move the teeth a quarter of a millimeter at a time.

To ensure the smooth progression of the treatment, orthodontic treatment using the Invisalign appliance requires stringent dedication from the patient to wear the device as required.

Invisalign process

Knowing what to expect from your Invisalign treatment process will help you decide if this route is the right one for you. Here is a detailed step-by-step of what’s involved in getting these invisible braces, including the diagnosis and treatment.

  1. Step 1: Initial consultation

The first step in the process will involve a visit to the orthodontist. At this first appointment, your dentist will examine the conditions of your teeth and oral tissues. They will discuss with you the treatment protocol and whether or not it is a treatment you should consider getting.

  1. Step 2: Molding process

If you are deemed an eligible candidate for Invisalign, your doctor will then take a digital scan of your mouth using an intraoral scanner.

intraoral scanner

This device then transfers the pictures of your mouth to software that will then create a 3D image of your mouth and jaw.

Using this image, your dentist put together a treatment plan for moving your teeth into their proper places. The software also allows them to predict the estimated length of the treatment.

The images are then sent to a lab for fabrication.

  1. Step 3: First fitting

When your trays arrive from the laboratory, you will be called in to pick them up. During this appointment, your ortho specialist may fit small attachments on your teeth to help the aligners stay in place.

With your trays fitted and ready to go, you will then be given instructions on aftercare, proper wear techniques, and the total recommended wear time.

  1. Step 4: Follow-up appointments

It is your time to return to the dentist after a few weeks of your trays being fitted. Your dentist will assess your tooth movements and how well the aligner trays fit. 

You will have to go in to receive your new aligner trays every one to two weeks, depending on the treatment plan. You can also return periodically to check the progress of your teeth or spontaneously if you experience any problems.

  1. Step 5: Final appointment

After the recommended treatment duration, you can then return to your dentist to make sure that the treatment is complete. You may be fitted for your retainer during this appointment or the next and be asked to wear them as recommended. 

Your teeth are in a fragile state after they achieve their new positions from aligner therapy. Retainers are custom-made devices prescribed to patients after their orthodontic treatment to help keep them in their newly designated places and prevent relapse from occurring.

How long does Invisalign treatment take?

Several factors can influence orthodontic treatment time with Invisalign braces like patient compliance to wear of the device, complexity of malocclusion, or other complications that may arise throughout the treatment process.

Clear Aligners vs. Traditional Braces

While Invisalign and traditional braces are both excellent methods to fix crooked teeth, there are some key differences between the two.

Aesthetics and appearance

Traditional metal braces use brackets and wires to form the framework that helps align the teeth. Unlike braces, these aligners use thermoplastic material to do the same. Comparatively, the latter is preferred due to how sleek it looks.

Comfort and convenience

The Invisalign system promotes comfort and ease of wear with its trays. Patients can remove the aligners as they please which cannot be the case for fixed metal appliances like braces. Metal braces also cause nicks and cuts to the tissues.

Treatment duration

When comparing the two, there isn’t much difference in orthodontic treatment time.

Treatment with braces usually takes 24 months to complete whereas treatment with Invisalign takes anywhere from six to 18 months to move your teeth successfully.


Maintaining oral health while wearing braces can be difficult as food particles get stuck between the metal wires.

Braces Clean

With the smooth finish of plastic aligners, you can keep your teeth and gums free of trapped food and maintain better oral care.


A retainer marks the end of the treatment for both clear plastic braces and metal braces. The duration of wear will depend on the complexity of your case.

Aligners cost vs Braces cost

Conventional braces cost anywhere from $3,000 to $10,000 depending on the severity of the patient’s malocclusion. Aligners cost fairly cheaper with $3,000 to $8,000 being the typical price range.


While traditional metal braces might be the poster child of teeth-straightening, clear aligners win the title of ‘fan favorite’.
