After the initial examination, the dental condition can be analyzed, invisible correction can be carried out, and then the second step of silicone mold can be carried out. Generally, silica gel molds are taken twice, which can ensure their accuracy.
The silicone model will be sent to the manufacturer (Invisalign Orthodontics Association will send it to the United States), and the tooth condition will be scanned to the computer by computer scanning technology, and the computer will simulate the whole orthodontic process.
The manufacturer will send the animation plan to the attending doctor, and the doctor will explain it to the patient and strive for the patient's opinion. If there is no opinion, the appliance can be made.
After the appliance is completed, it will be sent to the doctor, who will distribute the appliance according to the actual situation of the patient and explain the precautions. The review time of invisible correction is usually once every two months. If you go out for a long time, you can review it for half a year, but you must wear the retainer according to the guidance of Dr. Xiamen Meilai, otherwise you need to make a new appliance if there is a problem.
There is a retention period of about two years after orthodontic treatment, and patients need to wear the retainer on time according to the doctor's advice to avoid tooth rebound.
