A Choice for a More Natural Smile
Orthodontic Solutions Tailored to Me at Gangnam Saero Dental Clinic
A Quick Look at the Types of Clear Aligners
From aspiring entertainers who dream of taking the stage where appearance matters, to office workers who constantly meet new people, international students who cannot easily spare time, soldiers, and people living in other regions, clear aligners are more than just a way to straighten teeth—they are an option that protects daily life while still delivering orthodontic results.
Because they are made of transparent material that is hardly noticeable, fit into daily routines with less disruption despite long treatment periods, and are comfortable with little to no bothersome foreign-body sensation or discomfort, many people prefer clear aligners.
In the past, Invisalign was practically the only brand, but now various types of clear aligners have appeared, greatly expanding patients’ choices.
However, as the options have increased, it is only natural to worry about which appliance is the right one. That is why Gangnam Saero Dental Clinic will organize the characteristics of each type of clear aligner accurately and in an easy-to-understand way.
Reasons for Choosing Clear Aligners

- Superior aesthetics
Clear aligners are made from transparent plastic materials that naturally fit closely against the teeth.
From a distance, they are so inconspicuous that they can look like retainers,
making it difficult for others to notice that you are undergoing orthodontic treatment.
However, because they are official orthodontic appliances rather than retainers,
precise alignment and bite correction are possible, just like with conventional wire and bracket orthodontics.
- Convenient and comfortable
Because they are removable,
you can take them out briefly for important events,
and there is no problem with food getting stuck or a thin wire poking your cheek.
There is also much less discomfort from speech issues or mouth sores.
- The least time burden
Conventional bracket orthodontics
requires visits to the clinic every 3 to 4 weeks
and a total treatment period of 1 to 2 years.
By contrast, clear aligners
require a visit once every 6 to 8 weeks,
with treatment typically lasting 6 months to 1 year.
(Of course, this varies depending on the patient’s teeth alignment and bite condition.)

How to Choose the Clear Aligner That Is Right for Me

Clear aligners differ by brand in their characteristics, advantages, and manufacturing methods. That is why, rather than deciding on your own, choosing the brand most suitable for you through a specialist’s accurate setup analysis and consultation is the surest way to prevent relapse, insufficient results, and treatment delays.
