Anti-mandibular can be judged by the patient’s facial shape, teeth occlusion status, X-ray cephalometric films, which need to be judged by a professional doctor.
1. Patient’s face shape: from the view of face shape, patients with bony antomandibular have concave face shape, that is to say, the lower jaw is more prominent, and the upper jaw is more concave than the lower jaw area, presenting a face shape with a more prominent chin.
2. Occlusal state of teeth: judging from the occlusal state, the distance between the upper and lower teeth of bony antimaxilla is relatively large, while dental antimaxilla generally has a smaller distance between the upper and lower front teeth, and will appear to be counter-covered.
3. X-ray cephalometric film: it refers to the cranial X-ray film for X-ray cephalometric measurement. When X-ray cephalometric measurement is carried out, the numerical difference between the upper and lower jaws can be measured. Normally, the lower jaw of the human body should be at the back side of the upper jaw, but if the lower jaw’s position is obviously in front of the upper jaw and exceeds the upper jaw, the phenomenon is bony antimandibularity.
Anti-mandibular is usually divided into dental anti-mandibular, bony anti-mandibular, functional anti-mandibular, you need to go to a professional dental hospital for relevant examination, to clarify the type of anti-mandibular, for different types of anti-mandibular, the treatment method is also different.
