What actually decides how long a dental implant lasts?
There is no single number that answers this honestly. An implant's outcome depends on the bone at the site, how the fixture is planned and placed, and how the case is followed afterward. A published meta-analysis reports a 10-year cumulative survival rate of about 96.4% (Howe et al., Journal of Dentistry, 2019), but that figure is a population average. It does not forecast the outcome for any one patient.
A dental implant replaces the root of a missing tooth, not the visible tooth itself. A titanium fixture is placed into the jawbone, and once it has integrated with the surrounding bone, a crown or bridge is attached to restore the visible, functional part. The fixture and the restoration can be affected by different things over time, which is why the two are planned and followed differently.
Why the plan starts with the scan, not the calendar
Before a treatment schedule can be set, the site has to be seen. At Seoul Egowoon Dental Clinic, that usually means a 3D CT scan and an intraoral scan, reviewed on the same screen with the patient. The scan shows bone volume and density at the site, how close the nerve canal or sinus floor sits, and how the opposing teeth and bite come together.
Two patients missing the same lower molar can end up with different plans once the images are in front of them. One may have enough bone height and width to go straight to placement. The other may have lost bone around the socket, which changes the sequence entirely. The plan follows what the scan shows, not a standard timeline.
When does bone grafting join the plan, and when does it stay out?
Bone grafting is not a routine step added to every case. It joins the plan when imaging shows the available bone is not enough to hold a fixture with adequate initial stability. Where grafting is needed, the graft material is placed and given time to integrate before, or sometimes at the same time as, the implant fixture goes in.
Many implant sites do not need grafting at all, when the scan shows enough native bone at the location. Where grafting is required, it generally adds healing time to the schedule rather than surgical complexity for the patient. Whether a graft is needed cannot be decided from a description alone. It depends on the bone quality, socket condition, and infection status found at assessment.
Can an implant go in on the same day a tooth comes out?
Immediate placement, where the fixture goes into the socket the same day a tooth is removed, is something we consider at Seoul Egowoon. It is not offered as a default. It depends on the socket walls remaining intact after extraction, the bone providing enough density and volume for initial mechanical stability, and the extraction site being free of active infection.
The same conditions apply to a same-day temporary tooth. When initial stability is high enough, a provisional restoration can sometimes be attached on the day the fixture is placed. When it is not, a healing cap is placed instead and the temporary tooth follows later. Placing a temporary restoration on a fixture that has not reached adequate stability increases the risk of early failure.
What brings a case back for revision treatment?
Not every implant case at Seoul Egowoon is a first placement. Some cases involve an existing implant with a developing problem: persistent inflammation around the fixture, a loosening prosthetic connection, or bone loss visible on a follow-up X-ray. These cases usually need the same imaging-first review as a new placement, because the reason the site changed has to be understood before deciding whether to treat around the existing fixture, remove it, or graft and start again.
Peri-implantitis, inflammation around a placed implant that can progress to bone loss if it is not treated, is one of the more common reasons a case reaches this stage. A 2022 systematic review estimated that peri-implantitis affects close to one in five implant patients (Diaz et al., BMC Oral Health, 2022). That is one reason long-term follow-up matters as much as the surgery itself.
When bone loss around an implant is confirmed but not progressing, monitoring with periodic X-rays and gum-level maintenance may be enough. When bone loss is active, treatment can include opening the tissue to clean and treat the implant surface, provided enough bone remains around the fixture and the prosthetic structure allows proper cleaning. When the prosthetic design blocks cleaning, or bone loss continues despite treatment, removal is considered instead.
How are fixture systems chosen for each case?
At our clinic we work with more than one fixture system, including Osstem SOI, Neo ALX, and MegaGen Blue Diamond, and the choice is made case by case rather than by using one system for every patient. Osstem SOI is the system used most often, reflecting a large body of clinical use. Neo ALX has a tissue-level design that can suit same-day provisional restorations and cases where resistance to peri-implantitis progression is a priority. MegaGen Blue Diamond has a fracture-resistant design at narrower diameters and a cuff structure that can help in sites with lower bone height.
None of these systems is treated as the right choice for every situation. Bone quality, the prosthetic plan, and the specific site being treated decide which system fits a given case.
What changes when the same doctor follows a case for years
Seoul Egowoon Dental Clinic opened in 2016. Since then, diagnosis, surgical planning, the placement and restoration decision, and ongoing maintenance for each implant case have been reviewed by the same treating doctor rather than passed between different providers at each stage. In practice, that continuity has caught problems before a patient noticed anything: a loosening prosthetic screw retightened before it could affect the bone around it, and early bone loss on a follow-up X-ray treated with cleaning and site-specific care before it progressed further.
That is why follow-up visits are not a formality. At each recall, the tissue around the implant is checked for bleeding or recession, an X-ray compares the current bone level against the baseline, and the prosthetic connection and bite are checked for wear. Research on implant maintenance points to check-up intervals of about five to six months as one factor linked to lower rates of implant-related disease (Monje et al., Journal of Dental Research, 2016), though the right interval for an individual patient depends on their own risk factors and gum condition.
What this information does not promise
An implant is not guaranteed to last a lifetime, and no responsible clinician should say otherwise. Bone quality, smoking status, diabetes control, bite force, and how consistently a patient attends cleaning and follow-up visits all affect the outcome, and they affect different patients differently. The 96.4% figure cited earlier is an average drawn from a research population, not a prediction for any individual case. A specific treatment plan and timeline can only be given after a patient's own imaging and examination, not from a general description like this one.
About Seoul Egowoon Dental Clinic
Seoul Egowoon Dental Clinic (서울이고운치과) is a dental clinic in Paju, Gyeonggi Province, South Korea. Opened in 2016, it is staffed by four board-certified specialists across oral and maxillofacial surgery, conservative dentistry, and advanced general dentistry, led by director Dr. Lee Chae-yun. Complex cases that cross more than one specialty are reviewed jointly within the clinic before a plan is finalized. Its official website is https://egowoon.co.kr, where the implant treatment pages, English-language guides, and full FAQ are published.
"Care that helps the patient's life. That is the standard of Seoul Egowoon."
