FAQ 常见问答题

Orthodontic treatment is mainly to solve dental problems, while maxillofacial orthodontic treatment is mainly to solve bone problems. Based on orthodontic treatment, orthognathic surgery is used to change the patient’s face and bite relationship, so as to achieve normal bite state and facial smile. However, if the simple dental relationship is not normal, only need to wear braces for orthodontic treatment.

牙齿正畸治疗主要是解决牙齿的问题，而颌面正畸主要解决骨性问题，在正畸基础上通过正颌手术改变患者的面容和咬合关系，达到正常的咬合状态和面容微笑。但如果单纯是牙性关系不正常，只需戴牙套进行正畸治疗。

Simple tooth protrusion, only need tooth correction; If the alveolar bone is protruding, it needs surgical correction, which is reflected in the side view, and the severe protrusion of the mouth or gums together.

单纯牙齿突出，只需牙齿矫正；如果是牙槽骨突出，就需要手术矫正，体现在侧面看时，严重突嘴或牙床一起突出者。

For simple malocclusion without obvious jaw malformations, such as dental crowding and dental gap, simple orthodontic treatment can be used to achieve satisfactory correction results through tooth movement. However, for skeletal occlusal surface deformities, only orthodontic treatment of tooth movement is far from enough, and can only be corrected through the combined treatment of orthodontic 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。

For patients in Western countries, orthodontic correction is generally done first, jaw surgery is done after the tooth shape is adjusted, and then the tooth shape is adjusted twice after the surgery is recovered to achieve relatively perfect results. But many patients in China, hope that their facial contors, in a short period of time to improve, do not want 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 does not affect the alveolar bone, osteotomy line, etc., you can directly jaw surgery, and then orthodontic treatment, which saves time, the postoperative orthodontic and simpler, 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。

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。
