What is mandibular protrusion? How to correct protruding lower teeth?

Lower jaw protrusionAlso known as underbite (reverse bite), is a condition in which the lower teeth overlap the upper teeth when the teeth are clenched. This condition causes both aesthetic and functional problems with the teeth.

1. Identification signs and characteristicsbelong topeople with lower jaw protrusion

Like many other forms of malocclusion,lower jaw protrusionof has its own identifying signs:

• The two jaws do not meet standard correlation, that is, the upper jaw is outside the lower jaw and is completely covered by the lower jaw.
• The inner tooth group may be in contact with the standard chewing surface but may not be, especially if the upper palate is too small compared to the lower jaw.
• Depending on the severity, the upper and lower jaw may or may not contact each other. The more severe the case, the farther the distance between the two jaws becomes when in a normal state.
• The chin - nose - forehead is not in a standard relationship but is skewed and broken in the middle of the face, so when looking from the side you will see a broken nose and chin protruding like a plowshare.
• The line connecting the forehead - nose is broken. It may be straight, but the line will be skewed left or right.

2. Causes of protruding lower jaw

2.1. Hereditary

This is the main cause of the lower jaw protruding. To put it more simply, you will inherit this condition if your grandparents or parents have this condition.

2.2. Bad habit

In young children, bad habits often appear such as: thumb sucking, pacifiers, incorrectly positioned tongue, etc. These are the causes of buck teeth in the lower jaw. Forming bad habits over a long period of time will affect the jaw structure and the direction of tooth growth, causing the jaws to bite incorrectly.

2.3. Premature tooth loss

Tooth loss can be congenital or due to strong external forces when not restored early, which is also a factor causing the overgrowth of the lower jaw.

At that time, jawbone loss at the missing tooth position will cause the teeth to tend to push against each other, accompanied by gum recession. In particular, if teeth are lost in the upper jaw, the jaw area will shrink, causing bone underbite.

When many teeth are lost, the underbite becomes more evident.

3. Treatment methods for people with lower jaw protrusion

Depends on the situationlower jaw protrusionWhether it's due to teeth, bones or both teeth and bones, doctors will recommend the most appropriate treatment method. Specifically:

3.1. Lower jaw surgery

There is only one solution for buck teeth in the lower jaw due to bone, which is surgery. Jaw surgery is performed as follows:

The doctor will make an incision into the gums just behind the jawbone on both sides of the lower jaw. Then, cut a part of the lower jaw bone and move it backward to create a balanced bite between the two jaws. Next, the doctor will fix the jawbone in the standard position by placing a plate or screw. Finally, the doctor will stitch the wound closed.

After completing the treatment process, you should have regular check-ups according to your doctor's appointment. This helps the doctor accurately assess the condition of the jaws after surgery and take timely measures if necessary.

3.2. Porcelain veneers fix the lower jaw

This is a method of overcoming lower jaw buckling that many people prefer.

The technology uses a thin layer of about 0.2 mm - 0.5 mm fixed with specialized glue to the outside surface of the back of the tooth when it has been ground according to the ratio. After implementation, the two jaw teeth are more balanced, have a standard bite and improve defects more effectively.

However, porcelain veneers are only suitable for certain conditionslower jaw protrusionmild dental disease. This method only helps change the shape and color of the tooth, but cannot move the entire root mass to the correct position on the jaw. Therefore, if you encounter a complicated situation, you need to consider and choose a more suitable method.

3.3. Lower jaw braces

Lower jaw bracesis an orthodontic method that uses archwires, brackets, elastic bands, etc. to create force to help bring teeth to the desired position. Not only does it improve sparse, crooked teeth... This method also improveslower jaw protrusionDue to effective teeth, including simple or complex cases.

Braces are an effective solution to improve lower jaw protrusion

Currently, there are many different types of braces such as:Metal braces, ceramic braces, lingual braces or clear braces. Depending on your bite condition, needs, and finances, you can choose the appropriate type.

Lac Viet Intech Dental Clinic is currently applying exclusive X - Matrix technology.Thanks to pioneering the use of artificial intelligence to provide personalized treatment plans for each patient, helping braces achieve perfect treatment results.

X - Matrix technology is a complex of three technologies: SmileStream, Autolign and Webceph.

Currently, on the market there are many different braces systems with very different technical specifications, designed to suit each specific bite deviation.

Smilestream with the RBT feature shows the position of teeth in the bone when different types of braces are attached, making it easier for doctors to choose the brace system and personalized torque that best suits the patient's condition.

The positioning and navigation technology in the algorithm helps choose a position with perfect adhesion of the braces on the tooth surface, limiting bracket peeling.

In addition, Webceph technology based on Cephalo film analysis and multi-dimensional images, multi-layer cutting helps reconstruct the lower surface layer to support doctors in evaluating treatment methods. At the same time, accurately calculate the entrance and exit of the upper and lower lip to coincide with the E aesthetic line and adjust the teeth and jawbone to create a V Line face without surgery.

In addition, Auto lign not only simulates the 3D results after braces in advance but also provides the ability to shape the dental arch and choose a personalized arch wire for each specific patient.

Therefore, X - Matrix brings X2 treatment effectiveness compared to traditional technology. In addition, if you are interested in dental implants come to Lac Viet Intech immediately!
