TOKYO HIGH DENTAL CLINIC
Clear Aligners
In brief
Clear aligner treatment straightens the teeth using a clear plastic tray instead of braces and wires.
Orthodontic care at Tokyo High Dental is handled from the first consultation to the end of treatment by Dr. Ahn Jin-gyu, who completed formal orthodontic training and a doctoral course at Tokyo Medical and Dental University. Treatment is planned after reviewing skeletal, dental and facial balance on a 3D high-resolution CT (VATECH).
Orthodontic treatment that straightens the teeth using a clear plastic tray
without braces or wires
The clear, thin plastic appliance is fabricated by taking a precise impression of the oral model
and going through a lab process that anticipates the exact treatment stages.
After the appliance is fitted, you visit the clinic at set intervals so the orthodontic staff
can check the tooth movement, take an impression, anticipate the next tooth movement, and fabricate the appliance.
Treatment period- 1 year to 2 years 6 months
Anesthesia- When screw placement is needed
Prescription- None
Visit frequency- Every 4 to 8 weeks
Recovery- Same as the treatment period
Aftercare- Regular check-ups by period
Advantages of clear aligners
The appliance is invisible, so it is aesthetically excellent.
A customized orthodontic appliance is made just for you.
Because you remove it while eating, there is no restriction on the food you eat.
It is comfortable to pronounce with, so the adjustment period is short.
You can remove the appliance at will for important situations or appointments.
It is more hygienic than conventional appliances and brushing is easy.
There is little chance of tooth decay, dental caries, or gum disease caused by the appliance.
Because it is examined and fabricated carefully every month, the staff can intervene in treatment easily as needed.
