CLASS THREE MALOCCLUSION
Imperfect positioning of your teeth is the basis for defining malocclusion. While malocclusion type two and malocclusion type one are both significant, we pride ourselves on providing patients with their desired transformation, in some cases up to the complexity of class three malocclusions. You can find out more below.
Classes of malocclusion
There are several classifications of malocclusion, and over time, some orthodontists have developed extensions and their own grading systems. However, most dental professionals adhere to the three malocclusion types developed by Edward H. Angle, considered by many to be the founder of modern orthodontics. He classified malocclusions based on the relative position and relationship of the maxillary and mandibular first permanent molars.
Can malocclusion be fixed?
Dental Crowding
Crowding means the jawbone doesn't offer enough space for your teeth to align properly. This results in teeth becoming crooked, overlapping, or twisting. It makes oral hygiene, and interdental cleaning difficult to maintain and is the most common reason adults need orthodontic treatment.
Overbite Correction
When your upper front teeth overlap your lower front teeth when your mouth is closed. A slight overlap of your lower front teeth is perfectly normal and nothing to worry about. However, a prominent overbite can cause problems such as biting your gums with your front teeth or biting the palate with your lower front teeth. An excessive overbite, when your upper front teeth cover your lower teeth when your mouth is closed, is known as a deep bite. A deep bite usually leads to increased wear on your front teeth.
Underbite Correction
Mild to moderate cases can be effectively treated with clear aligners, sometimes called invisible braces, such as those used by Impress. Aligners gradually move your teeth by applying gentle pressure. You wear the aligners 22 hours a day and only remove them to eat and drink, or for occasional special occasions.
What are the symptoms of malocclusions?
Symptoms can range from nonexistent to severe, depending on the type and severity. Common symptoms include: - Crooked teeth - Difficulty breathing through the mouth - Speech problems - Difficulty chewing or biting - Tongue and cheek biting - Cosmetic concerns, both related to your smile and facial features At Impress, we are happy to help you if you are experiencing any of these symptoms associated with crooked teeth.

How do you treat malocclusion?
CLEAR ALIGNERS
Mild to moderate cases can be effectively treated with clear aligners, sometimes called invisible braces, such as those from Impress. Aligners gradually move your teeth by applying gentle pressure. You wear the aligners 22 hours a day and only remove them to eat and drink, or for occasional special occasions.
TRADITIONAL BRACES
You're probably familiar with traditional braces, made of metal wires and brackets attached to your teeth. This is the most common method for treating malocclusion, as they're suitable for both children and adults. While traditional braces can address severe malocclusion, the treatment process is often slow. The wires are tightened over time to align the teeth.
PALATE SPACERS OR SPREADERS
Spacers are often used in conjunction with braces, either before or during braces treatment. They create space between teeth, usually between the molars, when there isn't enough room for the metal bands of the braces to fit around them.

Success & Smiles
Very impressed with the service
Very impressed with the service. The team are very professional, also the app is really good and clear, keeping you up to date and engaged with your progress. I like how you can compare your week 1 images to current images to see the progress and changes that have been made. Would definitely recommend to others. Oussama was very helpful. They gave me a courtesy call to check how I am finding things and asked me if there's anything else I need help with.

My experience with Impress
My experience with Impress has been great so far. The team has been supportive and responsive throughout the process. The aligners are comfortable, and I’ve already started noticing changes. Everything has been well-organised and easy to manage from home. Doctor “Danial” and Doctor” Sundas” are really Cooperative. They are really humble and nice.
