Office worker Kim recently finally got a consultation for orthodontic treatment that he had put off for years. The moment he received the estimate in the consultation room, his first thought was not about the treatment method but rather, 'How can I split this cost into payments?' As he left the dental clinic, he held both a guide on credit card interest-free installment plans and a brochure for the hospital's own installment payment program.

Non-Covered Treatment Means Heavy Upfront Costs Orthodontics is a non-covered treatment with limited insurance application, so the large upfront cost is the first reality patients face. For this reason, many dental clinics operate their own installment payment systems, and an increasing number also offer a method in which the hospital directly divides payments into stages, separate from long-term interest-free installments from credit card companies.

Two Main Installment Options... Card Installments vs. In-House Payment Plans Installment methods largely fall into two categories. One is payment via credit card, within the interest-free period offered through partnerships with card companies. The other is an in-house installment plan in which the hospital and patient contract directly and split the cost by treatment stage. Because orthodontic treatment involves a long timeline—extractions, appliance attachment, regular adjustments, and the retainer phase—stage-based installments are often explained as relatively reducing the burden.

Installments Are Not Unconditionally Advantageous... Verification Needed However, installment plans are not always advantageous. Card installments can accrue interest if you exceed the interest-free period, and in-house installment conditions vary by hospital, so refund policies in case of mid-treatment withdrawal must be carefully checked. In particular, it is important to verify at the consultation stage whether the contract clearly specifies the number of installments, penalty fees, and settlement criteria in case treatment is discontinued.

Three Things to Check Before a Consultation The following are cited as items to check before a consultation for those considering orthodontic treatment:

① Determine whether the installment plan offered by the hospital is genuinely interest-free or includes fees. ② Check refund policies in advance in case treatment cannot continue due to discontinuation or relocation. ③ Compare installment conditions across multiple hospitals and judge based on total payment amount.

Since treatment periods are long and cost structures are complex, installment conditions can vary by hospital and card company, so it is advisable to confirm through a consultation before signing an actual contract.
