What are midline braces? Is it effective?

What is midline discrepancy?

The midline is a straight line passing through the center of the upper and lower middle incisors. The mid-face line is a straight line passing through the point between the ends of the eyebrows and the center of the tip of the nose. Normally, the midline of the teeth of the two jaws will coincide with the midline of the face.

Misaligned midline is a condition in which the midline of the upper or lower teeth does not coincide with the midline of the face.

In fact, many people often compare the midline of the teeth with the center of the philtrum to determine whether the midline is straight or not. This method is correct in most cases, however there are also many people whose position of the philtrum is incorrect, causing confusion in

Causes of midline deviation

There are many causes of midline deviation, of which we can divide into 2 large groups of causes:

Skeletal midline deviation

Boneal structural abnormalities such as asymmetry in the length of the horizontal branch/vertical branch of the lower jaw on both sides, asymmetry maxillary bone due to cleft palate,....

These skeletal deviations will cause the tooth position of the entire jaw to be affected, leading to midline deviation.

Midline deviation due to teeth

There are many causes of midline deviation due to teeth:

Crowded teeth

When teeth do not have enough space to line up evenly on the jaw, they will move out of their correct position and cause a midline shift. The characteristic of midline deviation for this reason is that the upper and lower jaw lines can deviate to different sides depending on the degree of crowding on each side.

Tooth size disharmony

If a few teeth are too big or too small compared to normal, or have a deformed shape, they will cause the remaining teeth to shift and lead to midline deviation. The most common condition is that the teeth of the upper jaw are small in size.

Disharmony in the number of teeth: Missing teeth, extra teeth, impacted teeth, missing teeth

If there is a discrepancy in the number of teeth on one side of the jaw such as missing teeth, impacted teeth, impacted teeth or missing teeth due to pathology, the remaining teeth will tend to move towards the missing or missing teeth. This deviation will cause midline deviation.

Sparse gap

Sparse gap in the jaw is also one of the common causes of midline deviation. There are even many cases where the large gap is located in the middle of the two central incisors of the two jaws, making it impossible to determine the midline.

Functional slippage

Functional slippage is a false malocclusion condition due to the existence of occlusion obstructions in the jaw that cause the lower jaw to slide out of the correct position and find another position that can mesh the two jaws better. If this condition lasts for a long time and appears early, it will cause the patient to have real bone misalignment.

Are braces to correct midline misalignment effective?

It should be affirmed that braces are an extremely effective method to correct cases of midline deviation caused by teeth. However, when you experience midline deviation due to bone deviation, braces cannot improve the problem and must be combined with other measures.

 When tooth position deviations cause midline deviation, the doctor will use orthodontic appliances to apply force on the teeth and move the teeth to bring the midline to the correct standard. Effective braces methods in treating midline misalignment include:

•     Braces with outer braces
•     Braces with inner braces
•     Braces with clear brackets

So we can see that all current types of braces are effective in correcting midline misalignment due to teeth.

However, for braces to effectively correct midline misalignment, the doctor needs to calculate and measure. and plan the tooth movement very carefully. The reason is because a deviation of just 1mm can cause the midline to no longer be in the correct position. For this reason, before deciding to get braces to correct midline deviation, you should research carefully and choose a reputable dental clinic, which has a team of experienced doctors and modern equipment to support diagnosis and treatment planning.
