Braces are not just about moving teeth, but about finding harmony for the face and chewing function. Tien Dung's story is the journey of correcting underbite with a practical and safe solution. Thanks to the combination of modern orthodontic technology and a team of caring doctors, Dung has achieved a balanced smile, ending the inconveniences in daily life with a satisfying result.

NỘI DUNG BÀI VIẾT

Obsession with underbite leads to stomach pain

Nguyen Tien Dung has a face with "hotboy" features, but every time he smiles or chews, the underbite defect (also known as underbite) becomes apparent. This condition causes the lower jaw to move forward too much compared to the upper jaw, creating the appearance of a broken face when viewed from the side.

In fact, this is not the first time Dung has tried to fix his smile. When he was young, Dung's family used Facemask - a specialized jaw bone correction device for children. However, the hyperactivity of childhood and the removable nature of the equipment left that journey unfinished."At that time, I was a child, wearing it was cumbersome and lazy, so I just took it off and left it there, in the end it had no effect,"Dung shared.

As an adult, underbite is not just an aesthetic issue. Dung began to clearly feel that this affected the chewing function:

Difficulty in chewing:The jaws do not fit tightly, causing food to not be thoroughly crushed.
Frequent accidents:Dung often bit his tongue and cheek mucosa when eating quickly or talking.
Whole-body health consequences:The digestive system has to work twice as hard to compensate for the teeth, leading to prolonged stomach pain. directly affects the quality of life and work of a young man.

Fate with Lac Viet Intech and Doctor Ha Linh

Determined to find his smile again, Dung went to Lac Viet Intech. Here, you will be directly examined and consulted byDoctor Ha Linh- an experienced orthodontic expert.

After taking a Cone Beam CT scan and analyzing the Cephalometric skull, Dr. Ha Linh made a comment that made Dung feel very confident:"Dung's condition is an underbite due to the mandible growing too strongly. At the age of 25, the bone is stable, if you want to improve the angle 100%. tilting and bringing the lower jaw back as much as possible, jaw osteotomy is the only solution. However, with orthodontics alone, the doctor is committed to improving about 80% of both function and aesthetics with the technique of breaking the arch wire and moving it away."

This clarity and transparency of Lac Viet Intech met Dung's wishes. Dr. Ha Linh has come up with the most practical, safe and optimal roadmap for Dung's desire to not have surgery.

The journey to "save" complex underbite teeth caused by bone

In Dung's complex case, to achieve an 80% improvement for a case of underbite due to bone, the doctor used the sharp "weapon" of 3 orthodontic solutions:

WebCeph analysis:Doctor Dr. Ha Linh has created simulations of tooth movement directions on software. Accurate calculation of the inclination of the incisor axis helps the upper jaw "cover" the lower jaw in the most natural way without weakening the tooth roots.
Smile Stream:Traction control is extremely strict. Because this is a bone compensation case, the pulling force must be strong enough to change the tooth position but light enough not to cause trauma to the temporomandibular joint.
Personalized regimen:Dung designed a special braces system combined with supporting appliances to optimize the retraction of the lower dental arch.

Doctor Ha Linh shared:"We not only straighten the teeth, we calculate to change the relationship between the lips and chin of the patient." Dung, helps your face feel less broken, reaching the most harmony within the allowable orthodontic range."

Results "exceeding expectations" after more than 2 years of braces

After patiently accompanying Dr. Ha Linh, Tien Dung's day to remove braces has come. The results surprised everyone in the crew and Dung himself:

Standard bite:The upper jaw covered the lower jaw, the chewing function was completely restored. Stomach pain caused by not chewing carefully also gradually disappears.
Balanced angle:Although the doctor only commits 80%, the aesthetic change is huge. Dung's chin no longer looks too forward, his once "hotboy" face has now reached a mature, harmonious level.
Absolute confidence:Dung no longer worries about biting his tongue or being shy when smiling.

Tien Dung emotionally shared:"I know my condition is difficult, I just hope that eating normally is good. But the actual results make me much more satisfied than that."
