Invisalign MA (Mandibular Advancement) for Developing Underbite Correction

Invisalign MA for developing underbite correction, Yonsei Jeongwon Dental Clinic

Hello, this is Director Yoon Jeong-won of Yonsei Jeongwon Dental Clinic, an orthodontic clinic in Daechi-dong.

When a child has a recessed chin or an underbite, many people worry about the right time to start orthodontic treatment. In cases showing skeletal disharmony such as a recessed chin or underbite, it is very important to use jaw growth for correction at the appropriate time.

In the case of an underbite, growth correction should be started as soon as a reverse bite of the front teeth is detected. In the case of a recessed chin, it is best to assess the growth stage and begin during the pubertal peak growth period, when height suddenly increases, around ages 12 to 14 (roughly elementary school to middle school age). This is because the rapid skeletal growth during this period can be used to effectively improve a recessed chin.

Traditionally, recessed chin correction has used growth appliances such as Activator, Bionator, and headgear to improve the position of the lower jaw.

These growth appliances can produce very good skeletal growth improvement when children cooperate well. However, they also have several drawbacks. Because they first improve jaw growth, improvement of tooth alignment is only possible after the growth correction is finished. Therefore, if orthodontic correction is also needed after growth correction, the treatment period becomes long.

Another major drawback is that it is uncomfortable to wear the appliance and speak. Not only is the appliance visually unappealing, but speaking while wearing it is difficult, so in reality it is impossible to increase the daily wearing time.

Invisalign MA (mandibular advancement), the underbite correction appliance developed by Invisalign, addresses these drawbacks of growth correction. By placing a structure called a precision wing in the molar area of the existing Invisalign appliance, it moves the lower jaw forward in patients with a recessed chin, thereby stimulating lower jaw growth; in that sense, it can be considered an improved type of growth appliance.

This patient was a 12-year-old girl who visited the clinic with concerns about a recessed chin and tooth alignment. The patient herself wanted skeletal and dental improvement with a cosmetic appliance, so treatment was started with Invisalign MA.

Before and after Invisalign MA

First, before helping the lower jaw grow by advancing its position, we go through a preparatory process of arranging the basic tooth alignment so that the lower jaw can move forward effectively. After that, the MA appliance with blue wings attached to the Invisalign aligner is worn to help the lower jaw grow. Once the lower jaw position has grown and stabilized into a proper bite, the treatment is completed after final tooth alignment adjustments.

Growth correction is often called "first-stage orthodontics," meaning that after the first stage of skeletal improvement is completed, a second stage of orthodontics is needed for tooth alignment. This means that additional orthodontic treatment may be necessary for tooth arrangement after the first stage, which can lengthen the treatment period. When growth correction is performed with Invisalign MA in this way, it has the advantage of minimizing additional orthodontic treatment after growth correction while effectively improving both the skeleton and the teeth.

At Yonsei Jeongwon Dental Clinic, we have all the latest equipment needed for Invisalign orthodontic treatment, including the iTero Lumina 3D intraoral scanner, growth plate testing, and pre- and post-treatment simulations using the Morpheus facial scanner, allowing for more precise and systematic orthodontic treatment.

In addition, the cost of orthodontic treatment includes precise diagnosis fees and monthly fees (excluding retainer costs), so you do not need to worry about additional expenses. We also have a general dentistry department, so all treatments needed for orthodontics, such as extractions and cavity treatment, can be done in one place. To reduce the burden of paying a large amount all at once, we also offer an installment payment system, which makes it even more attractive.

Chief Director Yoon Jeong-won is in charge of the orthodontics department and has specialized only in orthodontics during 16 years of clinical practice, giving him extensive experience with many high-difficulty cases. Therefore, a wide range of malocclusions, protruding mouth, underbite, and other orthodontic issues can be treated effectively.

Perhaps those who are considering orthodontic treatment due to protruding mouth, crowded teeth, malocclusion, recessed chin, underbite, and similar concerns have already gathered a lot of information through searches for nearby dental clinics. Even so, comparing the different appliances in person and hearing detailed explanations about whether extraction is needed will be very helpful in making a decision.

During the consultation, you can compare a variety of appliances such as Clarity, Clippy C, and Invisalign with your own eyes and hear detailed explanations about their pros and cons as well as orthodontic treatment costs. We recommend calling or visiting for a consultation without hesitation.

Yonsei Jeongwon Dental Clinic in Daechi-dong, Gangnam, is close to Samseong Station, Hakyeoul Station, Daechi Station, and Hanti Station, making it very convenient for patients coming from Samseong-dong, Daechi-dong, Gaepo-dong, Dogok-dong, Irwon-dong, and Yeoksam-dong.
