FAQ 常见问答题

Patients in Western countries generally do orthodontic correction first, do jaw surgery after tooth shape adjustment, and then make secondary adjustments to tooth morphology after surgery recovery to achieve relatively perfect results; But many patients in China, hope that their facial contours, in a short period of time to be improved, unwilling to spend a year or two to do orthodontic correction, in this case, as long as the teeth do not affect the operation, such as the root of the tooth does not affect the alveolar bone, osteotomy line, etc., can directly lower the jaw surgery, and then carry out orthodontic treatment, which saves time, and the orthodontics after surgery is simpler, which is more in line with China’s national conditions.

西方国家的患者，一般是先做正畸矫正，牙齿形态调整好后做下颚手术，手术恢复好后，再对牙齿形态进行二次的调整，以达到相对完美的效果；但我国的许多患者，希望自己的面部轮廓，在短时间内得到改善，不愿意花一两年先做正畸矫正，这种情况下只要牙齿不影响手术，譬如牙根不影响牙槽骨、截骨线等，可以直接下颚手术，然后再进行正畸治疗，这样又省时间，术后的正畸又简单些，比较符合中国的国情。

For simple malocclusion, not accompanied by obvious jaw deformity, such as crowded teeth, dentition gaps, etc., simple orthodontic treatment can be used to achieve satisfactory correction results through tooth movement; However, for skeletal occlusal facial deformity, orthodontic treatment of tooth movement is far from enough, and can only be corrected through the combination of orthodontics and orthognathic surgery.

对于简单的错颚畸形，不伴有明显的颚骨畸形，如牙列拥挤、牙列缝隙等，可采用单纯的正畸治疗，通过牙齿移动，取得满意的矫正效果；但对于骨骼型的牙合面畸形，仅仅进行牙齿移动的正畸治疗，是远远不够的，只能通过正畸、正颚手术的联合治疗，才能得到矫正。

If orthodontic treatment has been done before the operation, the teeth are arranged neatly, and the dental space left after the operation is normal or close to normal, you can not do orthodontic; In fact, we found that a considerable number of patients, even if there is a certain gap in the teeth after surgery, but because it is hidden in the mouth, it is not easy to find, and they do not have orthodontics; Of course, for those who have not done orthodontics before surgery, the postoperative tooth spacing is too large or uneven, and the patients have high cosmetic requirements, and orthodontic adjustment is still needed.

如果手术前已经做过正畸治疗，牙齿排列很整齐，术后遗留的牙间隙，又正常或接近正常，可以不做正畸；实际上，我们发现有相当部分的患者，即使术后牙齿有一定的间隙，但因为隐藏在口腔内，不容易发现，也没有做正畸；当然对于术前没有做过正畸，术后牙齿齿距过大或排列不齐，患者美容要求高，仍然需要正畸调整。

The bones, nerves, muscle tissue, and blood vessels of the face make for the complexity of the maxillary protrusion surgery, which requires a highly skilled doctor to perform; If nerve tissue is damaged, it can lead to things like numbness in the jaw after surgery; Some may even cause facial paralysis without expression, which is a possible sequelae of maxillary protrusion surgery.

脸部的骨骼、神经、肌肉组织、血管，对于上颚前突手术来说，造成其复杂性，需要进行手术的医生需要非常熟练；如果损伤了神经组织，可能会导致手术后，出现下巴麻木等情况；有些甚至会造成面瘫无表情，都是上颚前突手术，可能导致的后遗症。

Anterior maxillary osteotomy, can be said to be a commonly used method to improve the protrusion of the mouth, mainly suitable for the teeth are not convex, only the gum protrusion; Double jaw surgery (double jaw surgery) refers to the incision of the upper and lower jaw bones, the operation of the upper and lower jaw bones at the same time, the incision between the joints of the upper and lower jaw bones, and then the upper and lower jaw bones, at the same time to correct the position of the operation

上下颚前部骨切开术，可以说是常用改善突嘴的方法，主要适合牙齿不外凸，仅牙床凸出的情况；而两颚手术（双鄂手术），指是把上下颚骨切开，上颚骨和下颚骨同时进行手术，从上颚骨和下颚骨的关节之间切开，然后把上颚骨和下颚骨，同时进行位置矫正的手术。
