IMPLANT
On day one, two Integrated Dentistry specialists use a 3D CT to first look for sites where an implant can be placed without bone grafting.
Overview
At Yeonhap Dental Clinic, two Integrated Dentistry specialists provide care, and your treating dentist follows you through consultation, surgery and the prosthesis. On the first day, a 3D CT is used to measure the bone on the cheek side and tongue side, and the distance to the maxillary sinus (the air space above the upper molars) and the nerve canal. The price of one implant is the sum of the fixture, the connecting post (abutment) and the crown; bone grafting and sinus lifts are charged separately when needed. Choose your situation from the 18 guides below.
These four numbers are Yeonhap Dental Clinic's criteria for reviewing a treatment plan; the final method is decided by the condition of your mouth.
Yeonhap Care
Two specialists analyze the 3D scanner and 3D CT data, place the implant at a position that protects the biologic width, and design the crown with a shape the toothbrush can reach at the gum margin (prosthesis emergence angle within 30 degrees) to reduce the risk of peri-implantitis.
We look for a position, within the range of the prosthesis, that leaves 2 mm of bone on the cheek side and 1.5 mm on the tongue and palate side, and graft bone if there is none. For upper molars, we consider a sinus lift when remaining bone is under 7 mm.
Osteoporosis drugs, anticoagulants and antiplatelet drugs, and diabetes medication are never stopped on your own; the timing is decided with the prescribing doctor. For diabetes, treatment proceeds within the range where blood sugar is controlled.

Treatments
Find your situation by tooth site, jawbone condition, number of teeth or retreatment, and continue to the standards Yeonhap Dental Clinic follows for long-lasting implants, plus the timeline, cost and insurance.
01 · Site
Three conditions for a length that matches the neighboring teeth
For a front tooth to emerge at the same length as its neighbors, the position, angle and bone must all be right. Yeonhap Dental Clinic places the implant inside the line connecting the edges of the neighboring teeth. If the gum condition and initial stability meet the criteria for immediate placement, we place it on the day of extraction and fill the cheek-side gap with bone graft material to 2 mm. With sufficient initial stability, we sometimes connect a temporary tooth adjusted so that chewing force does not load it directly on the same day.

02 · Site
Criteria for width, length and number
As a baseline, Yeonhap Dental Clinic uses a diameter of 4.0–4.5 mm for premolars and 4.5–5.0 mm for molars, with a length of at least 7 mm. For upper molars, we consider a sinus lift when remaining bone is under 7 mm; for lower molars, we check that 2 mm can be secured above the nerve canal. If that is not possible, we consider a short implant 5 mm or more in diameter and 4–6 mm in length. We place an implant even when only the last tooth, the 7th, is missing.

03 · Jawbone
Whether grafting is needed depends on 2 mm of cheek-side bone
If a position that leaves 2 mm of cheek-side bone and 1.5 mm on the tongue side can be found, no bone graft is done. In the group with less than 2 mm of cheek-side bone at placement, marginal bone loss one year after the prosthesis was connected was 0.36 mm, about 12 times the 0.03 mm in the group with 2 mm or more[31]. When needed, Yeonhap Dental Clinic does four steps on the same day as placement: making holes in the bone surface, graft material, a membrane and fixation. We do not do a staged surgery in which only the graft is done first, so the timeline is not lengthened because of it; the cost is charged separately.

04 · Jawbone
7 mm of remaining bone is the criterion
When remaining bone is under 7 mm, Yeonhap Dental Clinic considers a hydraulic sinus lift first. For a thin membrane or a lesion, we consider the lateral approach from the start. If a sign of perforation is unclear or confirmed, we switch to the lateral approach that day and place the implant at the same time depending on initial stability. From the first surgery to the final prosthesis takes about 4–5 months or 6–7 months depending on the condition, and 7–8 months in total if the sinus lift is done first.

05 · Jawbone
Four conditions for placing on the day of extraction
Immediate placement means putting the implant in on the day the tooth is pulled, to shorten the wait after extraction. Yeonhap Dental Clinic checks for removal of infection, fixation in 2–3 mm of bone below the socket, the distance to the sinus and nerve canal, and gum recession at the front teeth. If the conditions are not met, we wait at least 2 months for front teeth and 3 months for molars before placing.

06 · Jawbone
Planning bone, gum, lesions and bite together
Complex cases are treatments that plan the bone, gums, sinus lesions and bite together. Yeonhap Dental Clinic considers simultaneous bone grafting when cheek-side bone is under 2 mm, and a sinus lift when remaining bone in the upper molars is under 7 mm. For lower molars where 2 mm above the nerve canal cannot be kept with a standard length, we consider a 4–6 mm short implant, but we do not place one where the remaining height is under 5 mm. We also decide the order of gum reinforcement, lesion treatment and bite restoration.

07 · Whole mouth
How many implants restore a whole jaw?
Whole-mouth implants restore the teeth and bite of one whole jaw together. Yeonhap Dental Clinic divides 12 artificial teeth, up to the 6th tooth, into three segments and supports them on at least 6 implants in the lower jaw and at least 7 in the upper jaw. If the bone in the lower molar area is under 5 mm or the upper front area is lacking, we consider All-on-X, and we also compare an implant-supported denture depending on cost, maintenance and your preference. The 7th tooth is added after a trial period if needed.

08 · Whole mouth
How is it different from whole-mouth implants?
Yeonhap Dental Clinic's All-on-X fixes 12 artificial teeth as a single piece on 4 implants at the front of the lower jaw or 6 implants at positions 4, 5 and 6 on both sides of the upper jaw. If the bone allows, we first look at the three-segment fixed type, and choose based on placement limits, cost, maintenance and your preference. When the 4 lower-jaw or 6 upper-jaw implants meet a diameter of at least 4 mm, a length of at least 8.5 mm and an initial stability of at least 30 Ncm, and the connection design fits, a temporary tooth is attached within the same day to 1 week. Upper jaws that involve a sinus lift are excluded.

09 · Whole mouth
Who can manage with two, and who cannot
Yeonhap Dental Clinic's implant denture (IARPD) is a method in which a partial denture is attached to a bridge on top of the implants. The design for a completely edentulous jaw is 2 canine implants in the lower jaw and 4 in the upper jaw, and the lower jaw takes about 5 months. For patients aged 65 or older who are partially edentulous, National Health Insurance coverage applies separately to the implants and the partial denture depending on the conditions. There is no snap-on retention part to replace, but relining the inside of the denture, adjusting the clasps and checking the screws are still needed.

10 · Retreatment
Three problems that call for revision surgery
Revision surgery is judged by dividing it into peri-implantitis, fracture or loosening, and aesthetic or position problems at the front teeth. Yeonhap Dental Clinic first checks whether the implant body can be kept, and for peri-implantitis we check bone loss, changes in the stability value (ISQ) and the response to treatment together. For a loose screw or a detached prosthesis, we consider re-tightening or re-cementing; where an implant has been removed, we allow 2–3 months of healing, confirm the cause, and place again.

11 · Standards
Four-step palate anesthesia · 200 rpm low-speed drill
Yeonhap Dental Clinic uses a rinse, ointment and an automated anesthesia device as the baseline, and when palate anesthesia is needed, adds pressure for a four-step process. A low-speed drill at around 200 rpm is cooled with water, and the implant is placed with a flapless or minimal-incision approach depending on the bone and gum condition. Discomfort may last until around days 2–3 after surgery, so we check recovery at 1 week and 1 month.

12 · Standards
We prepare for each of six side effects
We explain the main side effects in six groups; their causes differ, so we prepare for each differently. The most common, peri-implantitis, is reported in about 22% of patients[25], and Yeonhap Dental Clinic reduces the risk by leaving 2 mm of cheek-side bone and designing a crown shape the toothbrush can reach (prosthesis emergence angle within 30 degrees)[30]. For altered sensation we keep 2 mm above the nerve canal, for sinusitis we treat it before surgery, and for front-tooth gum recession we reduce the risk through placement position and gap bone grafting.

13 · Standards
It is not that you can't — there is just one more step in the order
Diabetes, antithrombotic drugs and osteoporosis drugs are not reasons you cannot have an implant; they are items for deciding the order at the first consultation. Yeonhap Dental Clinic checks the drug name, how it is administered, how long you have taken it and the extent of surgery, then decides with your prescribing doctor only on the medications that need adjusting. How to take your medicine on the day of surgery is explained according to the type of drug and your meal plan, and the principle is that no patient stops any drug on their own.

14 · Standards
4 mm depth baseline · placement direction by site · a cleanable prosthesis
The difference shows up not on the day of placement but in the gum several years later. Yeonhap Dental Clinic uses about 4 mm from the gum surface to the platform as the baseline, sets the placement direction for each site, and makes the prosthesis with an emergence angle within 30 degrees and without a convex shape[30]. We refer to the association between shapes over 30 degrees or convex and peri-implantitis.

15 · Standards
About 96% 10-year survival, daily care and 6-month checkups
A 10-year survival of about 96% (93% when adjusted for dropouts) is the share not removed, and does not mean there was no inflammation or prosthesis repair[21]. Peri-implantitis was reported in about 22% of patients[25] and was lower in the regularly maintained group[28]. At Yeonhap Dental Clinic, you clean the prosthesis margin daily with a toothbrush and interdental brush, and we check every 6 months. Smokers have about twice the risk of failure[29], so we recommend quitting smoking for the first month after surgery.

16 · Timeline
How long it takes depends on the site
From placement to the final prosthesis, we expect about 3 months in the lower jaw and 4–6 months in the upper jaw. If an implant cannot be placed on the day of extraction, a wait of at least 2 months for front teeth and 3 months for molars is added. For a sinus lift, it takes about 4–5 months from the first surgery if the condition is good, 6–7 months if staged adaptation is needed, and 7–8 months in total if the lift is done first and the implant placed later. Yeonhap Dental Clinic explains the expected schedule at the first consultation.

17 · Cost
What determines it?
One non-covered implant costs MegaGen KRW 790,000, Dentis KRW 890,000, or Osstem BA KRW 990,000, including the fixture, a custom abutment, and the crown. Bone grafting and sinus lift are charged separately only when needed, and Yeonhap Dental Clinic gives an itemized estimate after a CT scan.

18 · Insurance
Where do you use the two covered implants?
Currently, patients aged 65 or older who are partially edentulous are covered for 2 implants per lifetime, with a patient copayment of 30% under National Health Insurance, 10% for Medical Aid Type 1 and 20% for Type 2. Bone grafting and sinus lifts are not covered. Expansion of the 2-implant coverage to completely edentulous patients is scheduled for January 2027. Yeonhap Dental Clinic decides the sites after looking at your remaining teeth, bite and partial denture plan.
