The Ihde Method
How many years does an Ihde implant last?
Published data cover a few years of follow-up; 'a lifetime' is an expectation, not a measurement
Answers to this question online usually start with '20 to 30 years' or 'a lifetime'. Those figures are general statements made about conventional implants; the data specific to corticobasal implants cover a shorter period. Below we have gathered the longest follow-up studies we could find on PubMed, what those studies measured and what they did not, and the things in your own hands that make an implant last longer.
Short answer
There are not enough data to give a definite number of years. The published studies we could find cover a few years of follow-up: the most detailed prospective study followed 1169 implants for at least 48 and at most 57 months; a five-year retrospective study reported 97 per cent success in 5108 implants. We could not find an independent follow-up study lasting more than ten years. What determines a long life today is planning, bite adjustment, cleaning and regular check-ups.

What the data say, and what they do not
The first distinction is this: the life of the implant and the life of the bridge on top of it are two separate things. The implant is the part anchored in the bone; the bridge is the part that takes the chewing load directly, wears down and needs repairing from time to time. Most people who ask 'how many years does it last' are really asking about both together. Publications also measure the two separately, and the answers come out differently.
The most detailed prospective study we could find on corticobasal implants was published in 2019. In 87 patients treated by a single clinician in Bulgaria, 1169 one-piece implants were followed for at least 48 months. In total, the same clinician observed 5100 implants for between 12 and 57 months, and 105 of these were lost. The author writes that high blood pressure, diabetes and smoking did not affect success. It should also be noted that the author sits on the scientific board of the International Implant Foundation and is a certified instructor for the foundation.
A retrospective study published in India in 2025 covers five years. Of 5108 implants placed for full-arch and partial bridges, 154 failed; the authors give the success rate as 97 per cent. The same study also counted the bridges separately: 5 of 170 metal-acrylic bridges, 6 of 206 full-arch metal-ceramic bridges and 11 of 215 partial bridges were damaged. In other words, both implant losses and bridge damage were recorded within five years; bridge problems should be counted separately from implant losses.
Shorter studies paint a similar picture. In a prospective study published in 2022, none of the 174 BCS implants placed in 20 patients were lost over 18 months of follow-up. In another study from 2021 covering 10 patients, 4 of 157 implants failed, a survival rate of 97.5 per cent. A review published in 2025 brought together 21 articles from the past ten years: in the 13 studies reporting success or survival, the rate for intraoral implants ranged from 90.3 to 100 per cent.
Watch out for two traps when reading these figures. The first is that 'survival' and 'success' are not the same thing: survival shows that the implant is still in the mouth, while success shows that criteria such as pain, mobility and bone loss have also been met. The second is that it is common for a large overall number to be quoted while the detailed analysis is done on a smaller subgroup. For example, the detailed results of the observation of 5100 implants are given only for the 1169 implants followed for at least 48 months.
What do we not know? In our search of PubMed, we could not find the abstract of a cohort study, independent of the circle that developed the method, that followed corticobasal implants for ten years or longer. Long-term studies comparing them with conventional implants in the same patient group are also very few. implantate.com, a patient portal in Germany, also writes that there is no evidence-based information on disc implants (BOI) and that the scientific professional bodies in Germany do not recommend these implant forms; this is the portal's assessment, not an official statement from a professional body.
The manufacturer's circle gives a bolder answer. The website of the clinic in Switzerland where Ihde treats patients states that, in ideal conditions, the Strategic Implant® lasts a lifetime. This is an expectation and the company's own statement; published follow-up periods are not yet long enough to confirm it. Saying so is not belittling the method; it is knowing the limits of the information you have.
On the bridge side, there is a general framework. Cleveland Clinic writes that with good care, implants can often last a lifetime, while the crowns and bridges on them mostly last around 15 years, and that this period can vary. This information relates to conventional implant-supported prostheses. In the Implant72 protocol, the bridge fitted on day three is the final bridge; but being final does not mean it will not wear. Its life is determined by how well the bite is balanced, night-time clenching and cleaning.
What makes an implant last longer, and what shortens its life
The rates in the publications are an average. In your mouth, the result is decided by the points below; some are in the dentist's hands, and some are in yours.
When it fits
- A bridge design that can be cleanedIf an interdental brush or a water flosser can reach under the bridge, plaque does not build up around the implants. A design that cannot be cleaned shortens the life of even the best implant.
- A balanced biteSpreading the load evenly across all the implants protects both the bridge and the implants. The adjustment made on the day the teeth are fitted and at the first check-ups shapes what happens years later.
- Regular check-upsGum inflammation or a loose screw caught early at a check-up is put right with a small procedure. If you do not come to your check-ups, the same problem grows.
- A night guard if you clench your teethNight-time clenching and grinding put regular excess load on the bridge. A guard takes this load off the bridge and onto itself; it works when it is worn regularly.
When it doesn't
- Neglecting cleaningAccording to the European Federation of Periodontology, poor oral hygiene, a history of gum disease and smoking are among the most common causes of implant loss.
- Uncontrolled night-time clenchingClenching without a guard means cracks and fractures in the bridge and excess load on the implants. In a five-year study, 154 of 5108 implants were lost and damage was recorded in 22 of 591 bridges.
- A history of untreated gum diseaseAccording to the EFP, a history of gum disease increases the risk of implant complications. If you still have some of your own teeth, they also need to be treated and looked after.
- Waiting for problems to go awaySlight movement in the bridge or bleeding from the gum grows the longer it is left. A problem reported early can usually be solved with a simple procedure.
A care and check-up routine for a long life
The steps below are the framework for the years after the teeth are fitted. Your dentist sets the intervals according to how your mouth is progressing.
- 1
The day the teeth are fitted: bite and record
When the final bridge is fitted, the bite is balanced. The product name, diameter and length of each implant are given to you in writing; this is the information that will prove useful years from now.
- 2
The first check-ups: fine-tuning
As the gum settles into its new shape, the bite is measured again and any spots that touch first are corrected. Small differences from the first few weeks are dealt with here.
- 3
Daily cleaning at home
Alongside a toothbrush, an interdental brush or a water flosser is used under the bridge. Your dentist shows you which tool suits your bridge.
- 4
Night guard
If one was planned, it is worn every night. A guard wears down over time; replacing it when it does is a cheap way of protecting the bridge.
- 5
Regular check-ups
A schedule is followed that is more frequent in the first year and less frequent after that. At each check-up the gum, the bridge, the screws and the bite are assessed, and X-rays are taken when needed.
- 6
Professional cleaning
Build-up in places you cannot reach at home is cleaned at the clinic. These appointments can be planned together with your check-ups.
What is known about how long the other options last
When comparing, the same measures need to be applied: how long the implant lasts, how long the bridgework lasts, and how much data supports each.
Conventional implants
There is a much longer and larger body of data. Cleveland Clinic writes that with good care an implant can often last a lifetime. If there is not enough bone, bone grafting is needed first.
Protocols with fewer implants, such as All-on-4
They have been in use for a long time and there are many studies on them. Because there are fewer implants, the load carried by each implant is higher.
Removable implant-retained denture
A denture that sits on a small number of implants. The implants can stay in place for a long time, but the denture's retaining parts and base are renewed at intervals.
Full removable denture
The route with no surgery. Because it does not stop the bone from shrinking, it loosens over time and needs regular relining or replacement.
The main problems that shorten an implant's life
Most of the problems seen in the long term start either in the bridge or in the tissue around the implant. These are the ones discussed most often.
Wear, cracks or fractures in the bridge
A five-year study recorded damage in some of the metal-acrylic and metal-ceramic bridges. When it is spotted early, there are more repair options.
Inflammation around the implant
When plaque builds up, mucositis develops first, and if it is not treated it can progress to peri-implantitis, which involves bone loss. Although the manufacturer's circle says it has not seen this with these implants, cleaning is essential.
Losing a single implant
Losses in the publications are low but not zero. In a plan where several implants are joined by a bridge, losing a single implant does not always mean losing the bridge.
Excess load
Night-time clenching or an unbalanced bite piles the load onto a single spot. Over the years it comes back as loose screws, a fractured bridge and bone loss.
A missing record
When nobody knows which product was used, even a simple repair years later can become difficult. A record does not directly make an implant last longer, but it keeps problems small.
The years after the teeth are fitted
Much of an implant's long life lies in the habits formed in the first few months.
The first few weeks
The swelling goes down and chewing gradually returns to normal. The bite is fine-tuned at check-ups, and you learn how to use the cleaning tools.
The first year
Check-ups are more frequent. The gum settles around the new bridge; small problems noticed during this period are easily corrected.
The years that follow
Check-ups become less frequent but continue. If a night guard is worn, it is checked for wear; if the bridge needs repairing, this is done early.
If you change dentist or city
With your implant record, a new dentist can carry on the follow-up. If you do not have a record, the first step is to ask the clinic that carried out the treatment for it.
Don't wait if
- The bridge moves or clicks. A fixed bridge does not move. Movement usually comes from a loose screw or a crack in the bridge; dealt with early, it needs only a simple procedure.
- There is bleeding, swelling or a bad taste around the gum. The European Federation of Periodontology lists these among the warning signs of disease around an implant. According to the Federation, untreated mucositis can progress to peri-implantitis.
- You notice a change in your bite. One side touching first, new pain when chewing or a tired jaw can show that the load is piling up in one spot. A few minutes of adjustment prevents a bigger problem.
- The bridge has a crack or a piece has broken off. A small chip can be repaired. If it is left, the crack can spread and a larger part of the bridge is affected.
- You have a fever, spreading swelling or difficulty swallowing. This picture suggests the infection is spreading. See a dentist the same day; if you are struggling to swallow or breathe, call 112 or go straight to A&E.
What determines the long-term cost
We do not give figures. But the real cost of a treatment does not end with the first bill; the care and repair items over the years also need to be taken into account.
- Check-ups and professional cleaning
- Regular appointments look like a small item, but they are what prevents most expensive repairs.
- A night guard and replacing it
- If you clench your teeth, a guard and replacing it over time is the lowest-cost investment you can make in protecting the bridge.
- The bridge material
- A five-year study recorded different numbers of damaged bridges for different materials. The choice of material affects the need for repairs later on.
- Terms for repairs and follow-up
- How things will be handled if the bridge needs repairing or a problem arises with an implant should be discussed in writing before treatment.
Frequently asked questions
How many years does a basal implant last?
There are no data that give a definite number of years. The most detailed published prospective study followed implants for up to 57 months; a five-year retrospective study reported 97 per cent success. We could not find an independent follow-up study lasting more than ten years. Today, planning, bite adjustment, cleaning and check-ups do most to determine how long an implant lasts.
Does an Ihde implant last a lifetime?
The website of the clinic where Ihde treats patients states that, in ideal conditions, the implant lasts a lifetime. This is the company's own statement and an expectation. Published follow-up periods are not yet long enough to confirm it.
Does it last less long than a conventional implant?
There are no comparative long-term data to say. The difference lies less in lifespan itself than in the body of knowledge: there are much longer studies for conventional implants, while the existing data on corticobasal implants cover a few years.
How long do the teeth fitted on day three last?
The bridge fitted on day three is the final bridge; no other bridge is made later to replace it. How long it lasts depends on how well the bite is balanced, night-time clenching and cleaning. A five-year study recorded damage in some of the metal-acrylic and metal-ceramic bridges, which is why the bridge is also assessed separately at check-ups.
Do smoking or diabetes shorten an implant's life?
A study from a team that uses the method reports that high blood pressure, diabetes and smoking did not affect success. The European Federation of Periodontology, however, lists smoking among the most common causes of implant loss. Giving up smoking works in your favour with any implant.
How often should I go for check-ups?
Your dentist sets the interval according to how your mouth is progressing; usually a schedule is followed that is more frequent in the first year and less frequent after that. What matters is that the check-ups do not stop.
If an implant is lost, does the bridge go too?
Not always. In plans where several implants are joined by a single bridge, what is done if a single implant is lost depends on the condition of the remaining implants. Reporting problems early gives you more options.
What do the percentages in the publications tell me?
They tell you an average, not your own result. When reading them, bear in mind that 'survival' and 'success' are different things, and check how long the follow-up was and how many implants the detailed analysis was done on. The authors' links with the circle that developed the method should also be noted.
