Dental implant warranty: which repairs are free?

01.Is the implant warranty legally fixed at one year?

One year is a period stated in Korea’s Consumer Dispute Resolution Standards, not a mandatory uniform warranty contract for every clinic. The standards are used for settlement or recommendations in disputes.

The Korea Consumer Agency explains that the standards apply when the parties have not separately expressed their intention concerning dispute resolution; more favorable criteria in other legislation take priority. If a clinic promises a longer warranty, read its duration and repair scope too.

For a “five-year warranty,” ask when the period starts. Implant placement and fitting the final crown can occur on different dates.

03.Is a broken or detached crown remade free of charge?

Reattaching a detached crown and making a new broken crown are different treatments. Where a new crown is needed, cost allocation depends on the crown’s warranty terms and the cause of damage.

The crown is the visible artificial tooth. Damage to the abutment or connecting screw underneath changes what needs treatment, so ask whether the existing crown can be reused.

If a new crown is needed, ask whether material and fabrication costs are covered. Tell the dentist if it broke after a fall or impact.

04.Does a loose screw mean the whole implant must be removed?

A loose screw does not automatically require removal of the entire implant. An examination distinguishes adjustment or replacement of connecting components from damage involving the fixture in the bone.

A 2014 case report describes treatment of an anterior implant’s loose abutment screw with reuse of the existing restoration. It concerns one patient and does not assess repair costs or warranty coverage.

For recurrent loosening, tell the dentist when previous repairs took place and what was done. Ask whether this visit involves an adjustment, a new screw or a new restoration.

05.Are reimplantation and bone grafting both free if the fixture comes out?

Ask separately about reimplantation, additional grafting and a new crown. Even with the one-year fixture-detachment criteria, any additional charge needs an explanation of its reason and how the warranty applies.

The fixture is the artificial root placed in bone. Its movement differs from a loose crown, so avoid repeatedly moving it yourself and have the clinic examine it.

Korean health insurance also has separate billing rules for removal and replacement after failed integration with bone. Having had the first implant covered by insurance does not make all reimplantation costs free.

06.Does the warranty cover gum inflammation or peri-implantitis?

Inflammation treatment is assessed separately from repairing a crown or screw. Ask what gum treatment is planned and whether insurance applies.

A case published by the Korea Consumer Agency in 2012 concerned implants lost or removed following peri-implantitis several years after placement. The agency described compensation for reimplantation and non-economic harm because maintenance and complications had not been sufficiently explained.

The issue in that case was pre-treatment explanation rather than simply the warranty period. It is an old, individual compensation case, not a present-day fee schedule or a universal peri-implantitis warranty rule.

07.Does one missed checkup or smoking cancel the whole warranty?

One missed visit alone should not be treated as a conclusion that all coverage has disappeared. The dispute criteria list missing two or more regular checkups as a circumstance allowing a separate charge.

Other listed circumstances include interruption of treatment because fees were not paid on time, inadequate disclosure of medical history, the effects of other trauma or disease, and detachment caused by the patient’s lack of care.

If smoking or grinding is cited as the reason for a charge, ask how it relates to this particular failure. Consider the clinician’s explanation alongside the exclusion clause in the warranty.

08.Does an insured implant have only a three-month warranty?

Three months is a period used to calculate health-insurance maintenance fees. HIRA’s March 2026 guidance says only a consultation fee can be billed for maintenance within three months after fitting the prosthesis, so a consultation charge may remain.

After three months, treatment and surgery for surrounding periodontal disease are billed under the relevant covered items, while prosthetic maintenance is non-covered. A clinic’s separate promise of free repair must still be considered even for an insurance non-covered item.

10.What happens if I move or the clinic closes?

When another clinic takes over treatment, ask separately whether it also accepts responsibility for the old warranty. Provide records, images, the warranty and implant product information, and ask about the cost of the new treatment.

Before moving, ask the original clinic how warranty processing works after a repair elsewhere. If it closes, obtain information about record storage and copies, and settlement of fees for unfinished treatment.

11.Can I still raise a concern after the warranty expires?

An expired warranty does not prevent separate examination of possible liability for problems in treatment or explanation. Time limits and whether liability is established depend on the particular case.

The Korea Consumer Agency’s 2012 material also describes screw loosening and fracture roughly two years after placement, requiring implant removal and replacement. Compensation addressed insufficient explanation of fracture risk and biting forces; it was not application of a one-year screw-replacement warranty.

Prepare records of when symptoms began and the explanations and treatment received. Seek individual legal advice if considering a damages claim.

In summary

Compare the scope of the treatment you may need, not just the longest advertised period. Written terms explaining whether coverage extends beyond the fixture to crown fabrication and extra surgery make it easier to request a clear explanation later.
