Because only when you wear invisible aligners, it will play its corrective role. 2. Since the invisible aligners move the teeth gradually in a certain order, it is important to wear and change the aligners according to the doctor’s instructions and the serial number of the aligners. Normally, the wearing time of each pair of aligners is 2 weeks. However, if the daily wearing time is less than 20 hours, the wearing time of each aligner may be extended by a few days to a week. Do not wear the aligners in a disorderly manner. 3. Please make sure to keep at least 3 pairs of recently used orthodontic appliances and store them in the box according to their corresponding numbers, in order to prevent the currently used orthodontic appliances from being lost, damaged or out of place. In these cases, your orthodontist may be able to find and reuse the last pair of well-fitting aligners in the reverse order of the original aligners, in order to maintain the results of the current treatment. 4.If you cannot wear the aligners according to the fitting time requirement, the orthodontic cycle will be prolonged, and it is difficult to guarantee the orthodontic effect. 5.Please follow the doctor’s instructions for regular follow-up. If you do not follow the appointment, the doctor will not be able to guarantee the results of orthodontic treatment. Any rescheduling or postponement of treatment should be approved by the attending doctor. Those who do not come back for follow-up for more than 3 consecutive months will be regarded as giving up the treatment automatically. 6.When wearing the aligners for the first time, there will be mild foreign body sensation, increased saliva secretion, discomfort in pronunciation, etc. Usually, it will be reduced or disappear in a few days.

Maintaining oral hygiene is of great significance to the success of orthodontic treatment, therefore, please maintain good oral hygiene habits and keep the orthodontic appliances clean in the process of orthodontic treatment. If the orthodontic appliances are not well cleaned, their transparency and aesthetics will be reduced. 9. According to the need of orthodontic treatment, some small attachments of the same or close color of the teeth are often bonded on some of your teeth to facilitate the retention of the aligners and the effective movement of the teeth. These attachments are almost invisible. Refusal to bond the attachments may affect the results of the orthodontic treatment. 10. The upper and lower teeth should be gently clenched together as much as possible during normal times, especially during the first 3-4 days after each change to a new set of Invisalign aligners. Doing so can make the aligners better in place and effectively play its orthodontic performance. 11. In some cases, it may be necessary to make some modifications to the design of the existing aligners, or it may be necessary to add a few more steps to the aligners, and if necessary, the doctor will not rule out the use of conventional fixed appliances to conclude the follow-up treatment for the patient. In order to obtain good and stable orthodontic effect, it may be necessary to use other auxiliary means in the process of orthodontic treatment. 12.During the treatment period, special attention should be paid to oral hygiene and cleanliness, and cleaning should be carried out after each meal, so as not to cause decalcification of tooth enamel, caries, periodontitis, gingivitis and other diseases. 13, the end of treatment into the maintenance stage, should be carefully use the retainer, otherwise there will be recurrence, but also should be regularly reviewed in order to find some problems in a timely manner.
