Implant Denture Guide: How Implants Hold a Denture, Who It Suits, and Health Insurance Status in Korea
An implant denture uses a few implants placed in the jawbone like buttons to hold a denture in place, and is commonly called an implant overdenture. It is considered when a complete denture that merely rests on the gums keeps moving or falling out. In Korea, implant coverage for people aged 65 and over currently applies only to partial tooth loss, where some teeth remain; support for toothless seniors is set to begin in 2027, so the detailed criteria should be checked.

What is the structure of an implant denture?
A few implants are placed in the lower or upper jaw, and button-shaped connectors or a bar are attached on top so that they engage with the inside of the denture. The denture can still be removed by hand and cleaned, but once inserted it catches on the connectors and moves less when chewing or speaking.
It is chosen because fewer implants are placed than for a fixed prosthesis that rebuilds every tooth on its own implant, and because planning is comparatively easier when the jawbone is insufficient. How many to place and where is decided by looking at jawbone height and width, bite and cost together.
- Implant: an artificial root placed in the jawbone
- Connector: a button-type device or bar attached on top of the implant
- Denture: a removable prosthesis with parts inside that engage the connector
Who should consider it?
The KDCA National Health Information Portal lists, among the cases needing implants, those who need implant support beneath a complete denture to maintain it and improve function. Many consultations come from people whose jawbone has shrunk so much that a lower complete denture lifts.
It is also necessary to consider whether general health allows implant surgery, and whether factors that affect jawbone healing, such as diabetes or smoking, are present. If weak hand strength makes it hard to insert and remove the denture on the connectors, a different design is considered.
What about health insurance?
Under National Health Insurance Service standards, implant coverage for people aged 65 and over applies only to patients with partial tooth loss, where some teeth remain, and procedures for completely toothless patients are excluded from coverage. In the senior denture benefit as well, dentures using special devices such as attachments are not covered.
According to the Ministry of Health and Welfare announcement published by Korea Policy Briefing on September 8, 2026, from January 2027 seniors with no teeth at all will also receive support for implant treatment costs. How the implant denture approach is included in this support will be set by public notice, so if you are planning now, it is safer to check the latest criteria with the NHIS and your dentist together.
What about treatment time and care?
The National Health Information Portal says implant treatment generally takes 3 to 4 months, and longer healing if a bone graft is needed. While the implants fuse with the bone, the existing denture is often adjusted on the inside and used temporarily.
After completion, the area around the implant connectors must be cleaned daily along with the denture. Connector parts wear with use and can lose gripping strength, so replacement is checked at regular visits. If the gums around an implant become inflamed, bone can be lost even if the implant does not loosen, so checkups every 3 to 6 months are advisable.
What should you ask at a consultation?
Cost and duration vary greatly depending on how many implants are placed and where, whether the connectors are button-type or bar-type, and whether the existing denture is modified or a new one is made. Check separately whether the quote includes implant surgery, connectors, denture fabrication and later parts replacement.
It is also good to ask in advance whether a bone graft is needed, what kind of denture is used while the bone heals after surgery, and how much it costs to replace worn connectors. If the 2027 toothless-jaw implant support is approaching, decide by checking with your dentist and the NHIS about the difference between starting now and waiting.
Common myths and facts
Myth: An implant denture never needs to be removed once inserted.
Most implant dentures are removable types that are taken out by hand and cleaned. The denture, connectors and the gums around the implants must each be cleaned daily to prevent inflammation.
Myth: At age 65 and over, you can get an implant denture through insurance right now.
Current senior implant coverage applies only to partial tooth loss, and procedures for fully toothless patients are excluded. Support for toothless seniors is due in January 2027, with detailed criteria to be set by public notice.
Frequently asked questions
How does an implant denture differ from a regular complete denture?
A regular complete denture stays in place only through adhesion to the gums, whereas an implant denture catches on implant connectors and moves less. In exchange, it adds implant surgery, a bone-healing period and connector care.
Can my current denture be turned into an implant denture?
If the denture's condition and fit are good, connector parts may be fitted inside the existing denture. If the denture is old and no longer fits, making a new one may be better, which is decided after an examination.
I recently received an insured complete denture. Can I still have an implant denture?
It is possible to proceed as an uninsured treatment, but whether coverage applies is a separate matter. The relationship between the toothless-jaw implant support starting in 2027 and the existing denture benefit will be set by public notice, so check with the NHIS first.
How often are the connectors replaced?
There is no set interval; they should be checked when the click felt on inserting the denture weakens or the denture comes out easily. The condition of the denture and connectors is checked together at regular checkups.
Can an implant denture be made for the upper jaw too?
It can, but the upper jaw has softer bone and, depending on the position of the maxillary sinus, the places where implants can be placed may be limited. An upper complete denture holds comparatively well through palate suction, so the need is often less than for the lower jaw.
