In today's world, Invisalign clear aligners are making headlines in the dental health landscape. These invisible braces balance aesthetics and hygiene in a good way. But do you know how does Invisalign work? Read on. 

What is Invisalign?

Invisalign or clear aligners method of orthodontic treatment that offers a clear alternative to traditional metal braces. Instead of using brackets and wires, Invisalign treatment uses custom-made aligner trays made from modern SmartTrack plastic to gradually straighten your teeth in a comfort manner.

Invisalign is a modern alternative to traditional braces, designed to straighten your teeth without the need for wires and brackets. The process begins with an initial consultation, followed by detailed 3D scans to map out a personalised treatment plan. These Invisalign trays carefully and gradually move your teeth into place, offering a discreet and comfortable option for achieving a straight smile.

The Benefits of Invisalign

  • Virtually Invisible: Unlike metal braces, which are easily noticeable, Invisalign aligners are clear and discreet. They blend into your daily life, allowing you to smile confidently without drawing attention to your orthodontic treatment.
  • Removable: One of the key benefits of Invisalign treatment is that the aligners are removable. You don't have to worry about food restrictions or struggle to maintain oral hygiene with braces.
  • Comfortable: Invisalign aligners are made from smooth plastic material, which means there are no sharp edges or metal components that can cause discomfort. You won't experience any wire poking or bracket friction like with traditional braces.
  • Customised Treatment: Each set of Invisalign clear aligners is crafted just for you. This personalised approach ensures that the aligners exert the right amount of pressure on specific teeth, resulting in efficient tooth movement.

The clear aligners are designed to be worn for 20- 22 hours a day, but they can easily be removed for special occasions or important events. Whether you're attending a wedding, job interview, or social gathering, you have the flexibility to remove the aligners temporarily and feel confident in your smile.

How Does Invisalign Work?

Your Invisalign journey starts with a comprehensive consultation at our practice. Using modern 3D imaging technology, we create detailed digital scans of your teeth. These innovative scans eliminate the need for traditional dental impressions, making the Invisalign process comfortable and effective.

Our modern planning software turns these scans into a customised treatment plan. You'll see a virtual preview of your smile's enhancement, mapping out each step of your teeth movement. This technology allows us to:

  • Calculate proper tooth movements and visualise the bite as treatment progresses
  • Determine treatment duration
  • Design your custom aligner sequence

If you wonder how does Invisalign work, it follows a structured way. Each set of aligners applies carefully calibrated pressure to specific teeth. This firm force stimulates the natural bone remodelling process, allowing teeth to shift gradually into their planned positions. The SmartTrack material ensures predictable, controlled movements of 0.25mm per clear aligner.

While Invisalign is a good option for many, it's important to consider the overall options associated with orthodontic treatments. If you're also exploring options like dental implants in conjunction with your Invisalign treatment, you might be wondering about insurance coverage for such procedures.

Maintaining Oral Hygiene During Invisalign Treatment

Proper oral hygiene remains essential during your Invisalign treatment. Your clear retainers create a close-fitting environment around your teeth, making thorough cleaning vital for preventing decay and maintaining fresh breath.

Daily Care Routine:

  • Brush and floss your teeth after each meal
  • Rinse aligners with lukewarm water
  • Clean aligners with a soft toothbrush
  • Avoid hot water - it can warp the plastic
  • Store aligners in their protective case

Preventing Plaque Build-up:

  • Remove aligners while eating or drinking
  • Rinse mouth with water if brushing isn't possible
  • Use antibacterial mouthwash to reduce bacteria
  • Schedule regular dental check-ups for comprehensive care
  • Keep aligners clean and bacteria-free

A consistent cleaning routine protects both your oral health and your aligners' clarity. Clean aligners are less noticeable but scores well at straightening your teeth. It's important to note that various factors, including genetics, can impact your oral health. At Innova Dental, we take a judgment-free approach to personalised care, understanding that poor oral health isn’t always due to lack of brushing.

Monitoring Your Progress and Treatment Duration

At Innova Dental our dentists use Dental Monitoring virtual care technology, which enables your progress to be reviewed remotely between visits. Our dentist will guide you on how this system works and whether it may be appropriate for your treatment plan.

Using your smartphone and the Dental Monitoring app, you'll capture images of your smile and send them directly to our team. With this approach, we can monitor your treatment progress in real-time, providing timely feedback and adjustments as needed to make optimal results. We will also see you every 2-3 months in person at the practice. These appointments allow us to:

  • Monitor tooth movement progress
  • Make necessary adjustments to your treatment plan
  • Provide new sets of aligners
  • Address any concerns or questions

Treatment duration varies based on your specific needs. Simple cases might take 6-12 months, while complex treatments can extend up to 24 months. Key factors affecting treatment time include:

  • Initial tooth position
  • Amount of movement needed
  • Compliance with wearing aligners 20-22 hours daily
  • Individual response to treatment

Our modern scanning technology creates detailed progress reports, showing the exact position of your teeth at each stage. These digital scans help us ensure your treatment stays on track for optimal results.

However, if you are experiencing severe dental issues that may require procedures like root canal treatment, it is crucial to address these before continuing with your Invisalign treatment. This will ensure that we can yield desired results from your orthodontic journey.

Post-Treatment Care and Retainers

Your stunning new smile deserves lasting protection. Wearing clear retainers after Invisalign treatment safeguards your investment by maintaining the alignment achieved during treatment.

Vivera® Retainers: Made by the creators of Invisalign, these custom-fitted retainers use the same SmartTrack material. Their durability and clarity ensure reliable protection while remaining virtually invisible.

Your orthodontist will create a personalised retention plan based on your specific case. Consistent retainer wear prevents tooth movement and protects your smile for a prolonged time.

However, if you're considering further enhancements to your smile beyond what Invisalign can offer, such as veneers, it's essential to consult with a cosmetic dentist. These professionals can provide veneers that enhance your smile with natural, lasting results through personalised care.
