Invisalign is becoming an increasingly popular choice for adults looking to straighten their teeth. Unlike traditional metal braces, Invisalign uses a series of clear, customized aligners that are nearly invisible when worn. While Invisalign can treat a variety of orthodontic issues, one common problem it is used for is correcting crossbites.
What Is a Crossbite?
A crossbite refers to an abnormal bite alignment in which the upper teeth sit inside the lower teeth when biting down. This is the opposite of a normal bite, where the upper teeth slightly overlap the lower teeth. Crossbite usually occurs because the upper jaw is narrower than the lower jaw, causing the upper teeth to bite inside the lower teeth.
There are two main types of crossbite:
Anterior crossbite -
where the front teeth bite inside the lower teeth. This is the most common type of crossbite.
Posterior crossbite -
where the back upper teeth bite inside the lower teeth. This is often seen with a narrow upper dental arch.
Crossbite can lead to abnormal tooth wear over time as well as put stress on the jaw joints. Therefore, orthodontic treatment is usually recommended to correct crossbites, especially in children.
How Invisalign Corrects Crossbite
Invisalign works through a series of removable plastic aligners that are custom-made to fit your teeth. Each set of aligners applies light force to slowly move the teeth into the proper position over time.
For crossbite correction, Invisalign aligners help widen the upper dental arch while bringing the upper teeth into their normal position over the lower teeth. Special attachments may be bonded onto certain teeth to help with the crossbite movements. There are also bite ramps that can be incorporated into the aligners, which help guide the lower teeth into the correct position.
One of the major benefits of Invisalign is that it allows for precise control over the teeth movements needed to correct a crossbite. The aligners are computer generated based on the exact specifications from the orthodontist near you.
Timeline for Correcting Crossbite with Invisalign
For mild to moderate crossbite cases, the average timeline for correction with Invisalign ranges from 12-18 months. However, the exact length of treatment depends on several factors:
The severity of the crossbite -
Mild crossbites are quicker to fix than severe cases involving multiple teeth.
Age of patient -
Teens tend to achieve faster results than adults since their bones are less dense.
Cooperating with treatment -
Wearing aligners for 20-22 hours daily speeds up the timeline.
Additional treatments -
Some patients may need additional appliances like expansion devices to enhance Invisalign's effectiveness.
Overall oral health -
Good oral hygiene and non-extraction treatment lead to quicker movements.
Here is a general timeline guide for Invisalign crossbite correction:
Mild crossbite -
Typically resolves in 6-12 months
Moderate crossbite -
Takes around 12-18 months
Severe/complex crossbite -
Can take 18 months or longer
Teens -
Movement is 30-50% faster, so time is reduced
Adults -
May require up to 24 months in some cases
The first step is to schedule an Invisalign consultation to get an accurate time estimate based on your specific crossbite. The orthodontist will take scans and x-rays of your teeth to plan out the custom treatment.
During the course of treatment, you'll switch to a new set of aligners around every two weeks. Appointments are needed every 4-8 weeks to monitor your progress and obtain new aligner sets. Once the crossbite is corrected, retainers will be provided to keep your teeth in position.
Benefits of Correcting Crossbite with Invisalign
While Invisalign aligners are nearly invisible, the benefits extend far beyond aesthetics. Correcting crossbite leads to improved dental function and health.
Benefits include:
Straighter teeth and a proper bite alignment
Eliminates abnormal tooth wear from crossbite
Reduces risk of dental decay or periodontal disease
Balances facial symmetry by aligning jaws
Relieves jaw joint pressure and discomfort
Boosts chewing efficiency and bite force
Enhances speech clarity
Improves self-esteem and smile
In conclusion, correcting crossbite with Invisalign typically takes 12 to 18 months depending on the severity. For a personalized treatment plan and timeline estimate, consult an experienced Invisalign orthodontist such as those at dental office near Park West, Culver City. With Invisalign, you can discretely fix crossbite issues and improve your smile and oral health.
