Invisalign

Invisalign is a clear, removable aligner system that straightens crooked, overbites, or spaced teeth to a beautiful alignment. The clear aligners are personally designed based on each individual's uniqueness to fit snugly to the teeth using advanced 3D computer-imaging scanning technology that visualizes the results of the teeth's transformation from the initial digitally scanned image at the start of the treatment. Invisalign corrects the appearance of the teeth by gently repositioning the misaligned teeth into a proper position within a predictable timeframe. Invisalign orthodontic appliances have been widely accepted by dentists worldwide for their ability to effectively resolve a variety of dental issues. Orthodontic appliances are designed and manufactured to comfortably cover the teeth, gradually shifting the teeth into a proper position, revealing a naturally beautiful alignment of a brighter smile and greatly boosting the owner's confidence wonderfully.

What is Invisalign?

Invisalign clear aligners are made of FDA-approved SmartTrack BPA-clear plastic material for their safety and high flexibility, allowing them to help those who have crowded teeth, gapped teeth, or a crossbite practically. Invisalign clear aligners are thin, colorless, and blend in with natural teeth perfectly. Orthodontic appliances are easily removable for cleaning, eating, or performing daily activities. Invisalign is comfortable to wear without sharp edges to disturb the gums or bulging cheeks and is virtually invisible, as if you didn't wear braces.

How does Invisalign work?

Invisalign clear aligners work by creating and transmitting a light, continuous force onto the custom-made trays according to a digital plan, which controls the direction of misaligned teeth movement to gradually move teeth toward the position specified by the dentist in the treatment plan.
Unlike other types of orthodontic appliances that require constant visits to the dentist to adjust the aligners periodically, the Invisalign specialist designs and builds multiple sets of clear aligners at the outset and clearly defines the changing time of the Invisalign equipment on average every 1-2 weeks, potentially saving time and helping reduce treatment costs.

What kind of dental issues can Invisalign fix?

  • Spaced teeth: Those with gaps between their teeth that are wider than normal for 2 or more teeth.
  • Crowded teeth: Those with crooked teeth, crowded teeth, or teeth that are pushed forward or backward due to insufficient space in the jaws.
  • Overbite: A condition in which the upper teeth protrude over the lower teeth, causing malocclusion between the upper and lower teeth.
  • Underbite: Those with protruding lower teeth relative to the upper teeth, makes it difficult to chew food.
  • Crossbite: Those with malocclusion of the teeth caused by the arch length deficiency
  • Deep bite: The condition where the upper front teeth excessively overlap the lower front teeth, making them virtually invisible.
  • Open bite: Those with malocclusion of the teeth between the back teeth and the front teeth, in which the back teeth can occlude but the front teeth cannot.

How many types of Invisalign?

  1. Invisalign Express: This type of aligner is suitable for those with uncomplicated teeth issues, such as mildly crooked teeth, slightly spaced teeth, or those who fail to wear retainers as prescribed by the dentist, causing progressive misalignment. The treatment typically involves the use of 7–14 clear aligners and takes 3-6 months to complete.
  2. Invisalign Lite: This type of aligner is suitable for those with moderately complex alignment issues, such as mildly crowded teeth. The treatment typically involves the use of 14–28 clear aligners and takes 6–8 months to complete.
  3. Invisalign Moderate: This type of aligner is suitable for those who have moderate to severe dental issues, such as markedly crooked teeth, or misaligned teeth. The treatment requires an average of 26-52 clear aligners, but no more than 26 pairs, and takes 12-14 months to complete.
  4. Invisalign Comprehensive: This type of aligner is suitable for those who have very complicated dental issues, such as severely overlapped teeth or widely spaced teeth. This treatment consists of unlimited use of clear aligners, but no more than 99 pieces. The treatment time ranges from 2-4 years, depending on each individual’s condition.

Who can benefit from Invisalign?

  • Those who have limited time for dental visits, travel regularly or are usually busy.
  • Children or adolescents who are beginning to have dental issues, such as minorly misaligned teeth, may affect their future personalities; it is advisable to have an initial consultation with an Invisalign specialist to early assess the readiness of the teeth.
  • Those who have limitations in their careers or personal image, such as office staff, executives, business owners, sales staff, actors, singers, hotel staff, models, flight attendants, influencers, celebrities, YouTubers, and TikTokers.
  • Adults or individuals seek discreet orthodontic treatment without an obvious traditional metal brace.
  • Professional athletes such as rugby players, ice hockey players, soccer players, basketball players, American and football players.

Steps of the Invisalign process?

Invisalign clear aligners at MedPark Hospital adopt the international gold standard of treatment, prioritizing safety and treatment success outcomes to achieve the goal of symmetrical teeth alignment, preventing future severely crowded teeth, and allowing patients to smile confidently with an aesthetically pleasing smile.

Personalized treatment plan with an Invisalign specialist

  1. Initial consultation with the Invisalign specialist to address concerns, determine the purpose, and obtain personal requirements for performing Invisalign clear aligners.
  2. The Invisalign specialist takes a dental x-ray to assess the condition of the teeth and takes pictures of the teeth inside the cavity from various angles. If there is a dental issue determined, such as wisdom teeth removal, dental fillings, root canal treatment, or teeth scaling, the dental specialists will consider treating the issue before starting Invisalign teeth straightening.
  3. The Invisalign specialist will scan the teeth using a digital 3D computer-imaging scanning technology via the ClinCheck software system, which reveals the journey of the teeth transformation step-by-step from the beginning to the final achievement, including a plan to reshape the teeth prior to fitting the aligner and the button attachment plan that controls the direction of the teeth movement.
  4. The Invisalign specialist will clearly define the total Invisalign treatment timeline, the number of Invisalign clear aligner sets, and how long each set of Invisalign clear aligners must be worn. The data will then be sent to the Invisalign lab in the United States, where the Invisalign clear aligners will be manufactured.

A pickup appointment and try on a set of Invisalign clear aligners

  1. The Invisalign specialist schedules an appointment to pick up the first set of Invisalign clear aligners (approximately 3-4 sets per visit), tries to fit on the aligner, and provides the instruction and the duration on how to wear the Invisalign clear aligner for at least 20-22 hours per day for the best possible outcome.
  2. The Invisalign clear aligners can only be removed when eating, brushing, or flossing and are scheduled to be replaced approximately every 1-2 weeks until the treatment is completed.
  3. Before inserting the orthodontic appliances, the Invisalign specialist will attach the attachment button to each tooth to control the movement of the teeth in a specified direction.

A follow-up appointment to evaluate the results of the Invisalign treatment

  1. The Invisalign specialist schedules an appointment approximately every 6–8 weeks to follow up and evaluate the progression of teeth realignment and provides the next set of Invisalign clear aligners.

A completed Invisalign treatment, receive a retainer to maintain the teeth alignment

  1. At the end of the Invisalign journey, the Invisalign specialist will schedule an appointment to evaluate the treatment results and provide a set of retainer devices to maintain aesthetic tooth alignment and prevent unexpectedly re-misaligned teeth.
  2. The Invisalign specialist will prescribe the total duration of the wearing time and the amount of time to put on the retainer each day (for at least 20-22 hours). Wearing a set of retainers is crucial to avoid recurrent teeth realignment and to maintain a beautifully pleasing result.

Invisalign aftercare

  • Brush your teeth thoroughly after eating, and rinse with mouthwash to eliminate bacteria and keep your breath fresh.
  • Use dental floss to remove food particles between teeth and prevent bacteria from accumulating.
  • Clean a set of Invisalign clear aligners daily. Use a set of brushes and a cleaning solution to remove accumulated bacteria. Dry orthodontic appliances every time before wearing.

What are the benefits of Invisalign clear aligners?

Invisalign offers a number of teeth straightening advantages, including:

  1. Removable: Invisalign clear aligners are designed to be conveniently removable for eating, drinking, and cleaning, including brushing, flossing, or rinsing, and maintaining oral hygiene routines while still being able to enjoy meals and favorite drinks without having any irritation or diet restrictions, unlike traditional braces.
  2. Comfortable: Invisalign clear aligners are highly flexible and custom-made, thus fitting with everyone’s unique teeth and gum configurations. The aligners are akin to the mouthguard without any shape edges, worry-free of any painful nicks and cuts in your mouth edges that can cause wounds. Though the straightening can be mildly uncomfortable for the first phase of wearing it, the wearer will soon get used to it relatively quickly.
  3. Discreet: Invisalign clear aligners are virtually invincible, making it easier to maintain a professional look or personal image with bare visibility while providing a natural look with practical wearability, making it simple to balance careers and lifestyles without any self-consciousness or embarrassment and helping straighten teeth without anyone noticing.
  4. Predictable: Invisalign clear aligners use 3D digitally advanced technology to predict the outcome with a clear constructive treatment timeline, step-by-step from the beginning to the final solution, requiring a shortened treatment period and few visits to the orthodontist only when necessary.

What is the success rate of Invisalign?

Invisalign is a highly effective orthodontic treatment with a success rate of up to 96%. Most patients feel very satisfied with the final outcomes. Invisalign is also known for its precise treatment timeframe through the use of 3D computer-imaging scanning technology that reveals the results of treatment in advance. This allows both the Invisalign specialist and the patient to see the possibility of successful orthodontic outcomes.

Is Invisalign clear aligner suitable for everyone?

Criteria to determine Invisalign candidacy are a person with good oral condition as well as good oral hygiene best practices. Typically, the majority of adults and adolescents are qualified. However, the best way to know if Invisalign is the right solution for you is to schedule an appointment with an experienced Invisalign specialist to have an initial personalized consultation and plan just for you to achieve the result of an aesthetically beautiful alignment while enhancing confidence with a brightly beautiful brand-new smile.
