Restoring a Beautiful Facial Line

By moving the jawbone, protruding teeth and protruding mouth,
the condition of the teeth is improved and a good impression restored.

Restoring Tooth Function with Orthodontics

Improved occlusion makes eating easier,
and restores the overall original function of the teeth.

Maintaining Healthy Teeth

Correct tooth alignment improves occlusion so cleanliness
is maintained effectively and overall dental health improves.

A Transparent Appliance

Made of thin, clear plastic trays, it is highly esthetic. Unlike conventional braces that use brackets and wires, it is thin, transparent, mouthguard-shaped plastic.

Without attaching a device to the teeth and being removable, it helps with cleaning the teeth and is not noticeable — an orthodontic method many people prefer.

Treatment is shorter than conventional braces and the appliance is gentle,
so there is less pain, enabling effective tooth movement.

Fewer Clinic Visits

Invisalign has longer regular clinic-visit intervals than conventional appliances,
letting you enjoy a relatively free schedule.
