Dentofacial dysplasia refers to abnormal facial proportions and the abnormal relationship between the upper and lower teeth. The degree of abnormality is enough to be recognized by non-professionally trained people. As far as the face shape of Chinese people is concerned, the most common ones are bucket (moon) face shape, A protruding face with toothy teeth, a long face (excessive gum exposure) and a crooked face. These abnormalities in the jawbone and facial shape are often accompanied by malocclusion, causing obstacles in pronunciation, chewing, digestion, self-confidence and social interaction, and even attracting social discrimination. For example, people with protruding faces and retracted chins will People with long faces and exposed gums are considered stupid in the established wrong impression of ordinary people; for a girl, a protruding chin like the moon is considered to be lack of femininity or superstitious Unlucky. Therefore, in order to avoid embarrassment, these people will avoid eating some food that requires chewing or laughing in public places. Among the patients who seek treatment, at least one-third to more than half of them are under great mental pressure due to this. , and seriously affects their interpersonal relationships and affects the quality of life.

Myth – Orthodontics vs Orthognathic Surgery
Although abnormal dental and facial development can cause double obstacles in occlusion and aesthetics, for the vast majority of people, the refinement and coordination of facial appearance are their main concern and emphasis. That is to say, the facial appearance of teeth and jaws Developmental abnormalities are usually accompanied by malocclusion, and people with simple malocclusion do not necessarily have abnormal jaw and facial development. Among the patients who seek medical treatment, there are many people with abnormal maxillofacial development who have undergone orthodontic treatment. They often say, “Doctor, the problem of my bite and uneven teeth has been solved, but the shape of my face (protruding teeth) The characteristics of a convex face or a moon face are still there!” This means that for a person who originally needs orthognathic surgery, only simple orthodontic treatment is performed. Often, after several years of correction, the patient will still be dissatisfied with the shape of his face. Satisfied, the reason is that the alignment problem of facial bones has not been completely solved and improved. For people with dental and facial abnormalities, a successful treatment must include orthognathic surgery to improve the alignment of the patient’s upper and lower jaw bones or other facial bones, and even be combined with rhinoplasty, bone reduction, chin and eye plastic surgery.

What is orthognathic surgery?
“Orthognathic surgery” is performed to correct minor or severe abnormalities or unsightly abnormalities in the “jawbone (jawbone) – the facial bone covering the teeth” and “dentition”, so it can improve chewing, bite, and pronunciation. , and breathing. In addition to the above functional improvements, the patient’s appearance can also be greatly improved.
Who needs orthognathic surgery?
The simple answer is that a person with dentofacial dysplasia that is so severe that it is impossible to achieve a more refined and harmonious appearance through dental correction alone should be recommended to undergo orthognathic surgery. People whose dentition and maxillofacial bones develop abnormally, resulting in poor bite function and usually accompanied by disharmony in facial appearance, need orthognathic surgery. This is often attributed to an imbalance in the rate of development of the upper and lower jaws, which may be due to genetic or environmental influences, or trauma to the jawbone that occurs during development. What is often confusing is that “orthodontics” can correct your teeth’s bite (irregular teeth), while “orthognathic surgery” corrects your “disharmony between the upper and lower jaw bones”. In addition to changing the bite function, In addition to being good, it also greatly improves the coordination and beauty of facial appearance.

1. Bone tooth decay
2. Chin retrusion (no chin)
3. The chin is too long
4. Abnormal pronunciation and unclear speech
5. Malocclusion makes it inconvenient to bite and swallow.
6. Open bite (when biting, the mouth is still open, and there is still space between the upper and lower teeth)
7. Facial appearance looks inconsistent from the front or side
8. The upper and lower lips cannot be closed “easily” (closed forcefully does not count)
