Due to the large proportion of foreign patients in the orthodontic center, the traditional orthodontic treatment in the combined orthognathic and orthodontic treatment requires patients to be seen once a month, and the whole course of treatment requires patients to be seen about 30 times, which consumes a lot of time, energy and financial resources. In recent years, the department has established extensive cooperation with famous invisible orthodontic companies at home and abroad and based on this, established invisible orthodontic – orthognathic joint treatment process, which can significantly reduce the number of follow-up visits (expected to reduce to 1/2-1/3 of the number of traditional orthodontic follow-up visits) while taking into account the aesthetics, the specific clinical treatment process is as follows: 1. 2.After the orthognathic orthodontic discussion to determine the treatment plan, the invisible orthodontic patient will make an appointment for intraoral silicone rubber to obtain an accurate model (or intraoral scan); 3.Complete the preparatory work such as periodontal scaling (scaling) or endodontic treatment (filling) before the intraoral silicone rubber obtains an accurate model (or intraoral scan), and the wisdom teeth can not be extracted at this stage; 4.Come to our department for silicone rubber acquisition at the appointment time. time to our department for silicone rubber to obtain an accurate model of intraoral (or intraoral scan), patients with tooth extraction need to do intraoral retainer and then make an appointment time to see the digital tooth movement plan; 5. Patients with tooth extraction start extraction and need to wear retainer at night after extraction to maintain the position of other teeth; 6. Review at the appointment time to determine the digital tooth movement plan and arrange invisible braces production after agreeing to wear braces at the appointment time; 7. Review at the appointment time to wear braces, follow the doctor’s instructions, review on time, and begin to schedule surgery at the surgeon’s office according to the number of sets of braces (1-2 months before surgery need to be designed for a three-dimensional surgical plan, need to complete preoperative invisible orthodontic treatment 1-2 months before surgery); 8, one month after surgery at the orthodontist’s office to review to obtain an accurate model of the mouth (or intraoral scan) or bite relationship for postoperative 9. After the invisible braces are worn, make sure the intra-oral bite relationship is good to complete the whole treatment course of combined orthognathic orthodontic treatment, and conduct clinical follow-up. Note: Invisible orthodontics has indications, not every patient is suitable for invisible orthodontics, specific needs to be determined according to the clinical treatment plan; invisible orthodontic treatment is divided into two stages (preoperative and postoperative), the cost is the same as non-surgical invisible orthodontic treatment, no additional charges. In addition, the cost of invisible orthodontic treatment is the cost of traditional metal bracket treatment plus the cost of invisible braces materials and silicone rubber impressions.
