Do You Need a Bone Graft for Dental Implants in Korea?

Short answer: You need one if the CT shows the jawbone is too thin, too low or too soft to hold the implant. A small graft is usually done in the same sitting as the implant and doesn't add a trip. A large graft, or a sinus lift with little bone left, often means the implant goes in later or the crown waits about six months.

뼈이식, bone graft, is the line that changes a dental quote most. Nobody can promise you won't need one until the CT is done.

When do Korean dentists say a graft is needed?

When there isn't enough bone, in height, width or density, for the implant to hold. A dentist at Seran Hospital in Seoul told Sports Kyunghyang in September 2025 that bone can shrink within 3 to 6 months of an extraction.

The cases that tend to need grafting:

• A tooth that's been missing for years
• Long-term denture wear
• Severe gum disease (치주염)
• Upper back teeth, where the sinus sits just above the bone

What is the graft made of?

Four kinds, and Korean clinics use these names:

• 자가골, your own bone. Korean dental literature calls it ideal, but it means a second surgical site.
• 동종골, processed human donor bone.
• 이종골, processed animal bone, usually bovine.
• 합성골, synthetic bone substitute.

A Gangnam dentist writing in December 2025 called donor and animal bone widely used in practice. Ask which is on your quote.

Does a bone graft add a trip?

A small one usually doesn't. Korean hospital dentists describe the split simply: a little missing bone gets grafted at the same time the implant goes in. A large defect gets grafted first, and the implant is placed after the bone has regrown.

That second path is graft, wait, implant, wait, crown. It can turn the usual two trips into three.

What about a sinus lift?

It's the graft for upper back teeth: the sinus floor is lifted and the space filled with graft material. Koreans call it 상악동 거상술.

Two ways in. The crestal approach goes up through the implant hole itself. Korean dental studies credit it with shorter surgery and healing and less swelling. The lateral approach opens a small window in the side of the jaw. Better view, bigger lifts, more swelling and infection risk.

How much bone you have left decides it. One Korean study gives 5 mm or more of remaining bone as the level usually recommended for placing the implant during the lift. Several Korean studies waited 6 months before the next stage.

For a visitor, a lateral sinus lift is worth planning around. Expect some swelling, and ask the clinic when you can fly and what to avoid in the first days.

How much does a graft add to the price?

It varies more than the implant itself. Some Korean clinics fold a small graft into the implant price. One Seoul listing we checked in October 2026 marked bone graft as included at ₩880,000 to ₩1,580,000 a tooth (see implant costs).

Billed separately, one Korean price calculator gives unofficial 2025–2026 estimates of ₩200,000 to ₩500,000 ($140 to $360) for a small graft and ₩600,000 to ₩1,500,000 ($430 to $1,070) for a sinus lift.

Ask the clinic two things: what "graft included" covers, and what the price becomes if they find more bone loss on the day.

A recent CT or X-ray from home lets a clinic say whether a graft is likely. It isn't final until they scan you, so leave room in the budget and dates.

How we help with graft cases

• Send your X-rays or CT with the form. We come back with free, itemized quotes from 2–3 dental clinics, with the graft priced as its own line.
• If a staged graft adds a trip, we schedule every visit with the same clinic.
• An interpreter in the consultation room, so the graft plan is explained to you in English.

Frequently asked questions

How do I know if I need a bone graft for an implant?

Only a CT scan can tell. Grafts are more likely if the tooth has been missing for years, after long denture use or gum disease, and for upper back teeth.

Does a bone graft mean another trip to Korea?

A small graft usually goes in with the implant and adds no trip. A large graft is often done first, with the implant placed later, which can add one.

How much does a bone graft cost in Korea?

Some clinics include a small graft in the implant price. Billed separately, a Korean price calculator estimates ₩200,000 to ₩500,000 for a small graft and ₩600,000 to ₩1,500,000 for a sinus lift.
