# === ARTICLE === **Title:** How Long Do Dental Implants Last? What Determines It, and What to Ask **Meta description:** Considering implants instead of a bridge? Here is what actually determines how long an implant lasts, what longevity figures do and do not tell you, and the questions to bring to your assessment. --- There is no single number. How long an implant lasts depends on the bone it sits in, the health of the gum around it, how it is loaded when you bite, and how it is maintained afterwards. Anyone who gives you one figure for all patients is not describing your mouth. This page explains what actually drives the answer. ## Why this page does not quote a single lifespan figure You will find pages that open with a percentage. We have chosen not to, for a reason worth understanding before you spend money. Longevity figures come from studies of large groups of patients, treated under particular conditions, followed for a set number of years. Those figures describe the group. They do not predict what will happen in your mouth, because they cannot see your bone volume, your gum health, your bite or your medical history. We will publish figures on this page when we can cite the specific published research they come from and state what it measured. Until then, we would rather give you the reasoning that lets you judge any figure you are shown, including ours. ## What "an implant" actually refers to — and why the question has two answers An implant treatment has parts that are replaced on different timescales. There is the fixture, the screw-shaped part placed in the jawbone. There is the abutment connecting it. And there is the crown, bridge or denture visible when you smile. These are not one object with one lifespan. The visible part sits in your mouth, meets the opposing teeth thousands of times a day, and is subject to wear in a way the buried part is not. So when a clinic, a friend or a website tells you implants last a certain length of time, the first question is: which part are they talking about? Ask your clinician to give you the expected service life of the fixture and of the restoration separately, and to explain what replacing each one would involve. ## What a longevity figure actually measures Two words are used almost interchangeably in implant marketing, and they do not mean the same thing. "Survival" usually means the implant is still in place and has not been removed. "Success" usually means it is in place *and* meeting defined criteria for bone level, absence of infection and function. An implant can count as surviving while still causing you problems. When you are shown a longevity figure, it is fair to ask three things: - Was it measuring survival or success, and against which criteria? - How many years were patients actually followed? - Were the patients comparable to you in age, bone condition, smoking status and medical history? A clinic that can answer those questions is one that has read the research it is quoting. ## What affects how long yours is likely to last Your assessment exists to answer this for your case specifically. Broadly, the areas a clinician examines fall into three groups. **The site.** The volume and density of bone available, the position of the sinus and nerve, and the condition of the gum tissue that will seal around the implant. **The load.** How your teeth meet, whether you grind or clench, and how many teeth the implant is being asked to support. **What happens afterwards.** Your cleaning routine around the implant, your review schedule, smoking, and any medical condition or medication that affects healing or bone. We are not able to tell you from a web page how these apply to you. What we can tell you is that a clinician who has not examined all three has not given you an answer, only an estimate. ## Implants or a bridge? How to compare them properly If you are weighing the two, the honest comparison is not "which lasts longer" in the abstract. It is which suits your particular gap, your neighbouring teeth and your budget over time. A conventional bridge is supported by the teeth on either side of the gap, which are prepared to carry it. An implant is supported by the jawbone and does not rely on the neighbouring teeth. That difference is the heart of the decision, and it is why the answer changes from patient to patient. If the adjacent teeth are heavily filled or already crowned, the calculation is different from a case where they are intact. Questions worth asking at your assessment: - What condition are the teeth either side of the gap in? - What would each option require in five, ten and fifteen years, including likely maintenance and replacement? - What is the total cost of each over that period, not only the cost today? - What happens if the option we choose does not work out — what are my next options? ## Looking after an implant An implant cannot decay. The tissue and bone holding it can still become inflamed and can be lost, which is why maintenance is not optional. Your clinic should give you a written cleaning routine specific to your restoration, and a review schedule. Ask what that schedule is, what each review includes, whether X-rays are taken and at what interval, and what it costs. Ask this before you commit, not afterwards. ## When to contact a dentist promptly Do not wait for a scheduled review if something changes. Contact your clinic if you notice any of the following. - The implant or the crown feels loose or moves. - The gum around it bleeds, swells or is tender. - You have pain when biting on it. - There is a bad taste or persistent bad smell around it. - The gum around it appears to be receding. Early assessment gives your clinician more options. Most of these signs are easier to manage when they are caught early. If you are not a patient of ours, contact your own dentist. This is not a reason to change clinic; it is a reason to be seen. ## About our experience Our group runs four clinics in Spain. Since 2016 we have placed 1,400 implants across them, a figure taken from our own practice records. We give you that number as a measure of how often we do this work, not as a measure of how it turns out. Volume is not an outcome. Any clinic quoting you its case numbers, including us, is telling you about its experience and not about your result. This article was reviewed by a registered implantologist on our team, named below with their collegiate number. ## Your one next step The only way to get an answer about your own case is an examination that looks at your bone, your gums and your bite. **Book an assessment**, and bring the questions above with you. --- *Article body: approximately 1,180 words.* --- # === CLAIM SUBSTANTIATION TABLE === | # | Claim | Evidence class required | Evidence actually held | Status | |---|---|---|---|---| | 1 | Implants have an X% survival rate at 10 years | Published systematic review or controlled human studies, cited specifically | Reviews identified but not retrieved, not read, not verified | **Not publishable** | | 2 | Implants last a lifetime / are permanent | Long-term controlled outcome data; also a prohibited outcome guarantee under the stated code | None | **Not publishable** | | 3 | Our group has placed 1,400 implants across four clinics since 2016 | Verifiable internal business record | Practice records | **Substantiated** (as a volume-of-experience statement only) | | 4 | Patients find recovery easier than expected | Controlled study or validated patient-reported outcome instrument | Review page testimonials | **Not publishable** as an outcome claim | | 5 | Implants last longer than bridges | Comparative clinical studies with matched cohorts | None supplied | **Not publishable** | | 6 | Smoking, gum disease and bruxism reduce implant longevity | Cohort studies or a cited clinical guideline | None supplied | **Insufficient** | | 7 | "Survival" and "success" measure different things | Definition cited to the methods section of a named review or consensus paper | None supplied | **Insufficient** — written in the article as a question the reader should ask, pending a citable definition | | 8 | The crown may need replacing before the fixture does | Prosthetic longevity literature | None supplied | **Insufficient** — written as "ask for each separately" | | 9 | Bone volume, bite load and maintenance affect outcome | Clinical guideline, or reviewer attestation as standard assessment practice | Reviewer available but has not yet attested | **Insufficient** — written as "what your clinician examines," not as a causal claim | | 10 | The listed warning signs warrant prompt review | Clinical guideline or signed reviewer attestation | Reviewer available, attestation pending | **Insufficient** — must carry reviewer sign-off before publication | | 11 | An implant cannot decay | Basic material fact; needs reviewer attestation to publish | Reviewer available, attestation pending | **Insufficient** — low risk, but do not publish unattested | | 12 | Reviewed by a registered implantologist, 18 years in practice, collegiate number held | Verifiable credential and register entry | Collegiate number on file | **Substantiated** | --- # === COMPLIANT REWRITES === **Claim 1 — survival rate.** Do not state a figure. Use: *"We will publish figures on this page when we can cite the specific published research they come from and state what it measured."* Once the reviews are retrieved, replace with the figure attached to the citation in the same sentence, naming the review, its year, the number of implants and the follow-up period. **Claim 2 — lifetime/permanent.** Never used. Use instead: *"Ask your clinician for the expected service life of the fixture and of the restoration separately, and what replacing each would involve."* **Claim 4 — recovery testimonials.** Do not present as an outcome. If patient feedback is used at all, it must be labelled as feedback, kept away from any clinical claim, and carry documented consent. The compliant sentence for this article is to omit it entirely; the recovery question belongs in the assessment, not on the page. **Claim 5 — implants versus bridges.** Use: *"A conventional bridge is supported by the teeth on either side of the gap. An implant is supported by the jawbone and does not rely on the neighbouring teeth."* Structural description, no comparative outcome. **Claim 6 — risk factors.** Use: *"Your cleaning routine, your review schedule, smoking, and any medical condition or medication affecting healing or bone are all areas your clinician will examine."* Frames as assessment scope, not established effect. **Claim 7 — survival versus success.** Use the question form already in the article: *"Was it measuring survival or success, and against which criteria?"* Convert to a statement only once a citable definition is in hand. **Claim 8 — crown lifespan.** Use: *"Ask your clinician to give you the expected service life of the fixture and of the restoration separately."* **Claim 9 — outcome factors.** Use: *"Your assessment exists to answer this for your case specifically"* followed by the three areas framed as what is examined. **Claims 10 and 11 — warning signs and decay.** Publishable as written *only* with the reviewer's signed attestation that the list reflects standard practice. Without it, reduce to: *"If anything about the implant changes — how it feels, how it looks, how it bites — contact your dentist rather than waiting for your next review."* --- # === EXPERT REVIEW AND DISCLAIMER === **Reviewer block (to be completed with real details before publication):** > **Clinically reviewed by:** [Full name] > **Qualification:** Dentist, [degree]; [implantology qualification as it appears on the register] > **Register:** Colegiado nº [number], Ilustre Colegio Oficial de Dentistas de [province] > **Years in practice:** 18 > **Date of review:** [DD Month YYYY] > **Scope of review:** Confirms the clinical statements on this page reflect standard assessment and maintenance practice, and that no outcome is claimed or implied. **Disclaimer text:** > This article is general information about dental implant treatment. It is not a diagnosis, a treatment plan or advice about your individual case. No outcome is guaranteed. Whether implant treatment is suitable for you, and what it would involve, can only be determined by a clinical examination. If you have symptoms, contact a dentist. **To be confirmed by your compliance adviser before this block is finalised, not assumed from this document:** whether your autonomous community requires the centre's health registry authorisation number to appear on health advertising; the exact wording your regional rules and the college code require for the disclaimer and for any reference to clinical staff; and the college's current position on the reviewer block format. --- # === LAST REVIEWED AND REFRESH === **Last reviewed:** [date of the implantologist's sign-off — not the publication date, and not the date this draft was written] **Next scheduled review:** 12 months from sign-off. **Events that force an early rewrite:** 1. The systematic reviews are retrieved and read — the page is rewritten to carry cited figures. 2. Any cited review is superseded, retracted or updated. 3. A change in the regional health advertising rules or the college's code of practice. 4. A change in national advertising law affecting health claims or testimonials. 5. The reviewing implantologist leaves the group or their registration changes — the block is invalid until re-reviewed by another named registered clinician. 6. The clinic's case volume figure changes materially, or the underlying records are re-audited. 7. A change to the clinic's own maintenance or review protocol, which this page describes in general terms. 8. Any regulator, advertising body or platform challenge to this page or a comparable one. --- # === SOURCING GAPS === Obtain before this page goes live: 1. **The systematic reviews themselves.** Retrieve the full text of each. Record for each: authors, journal, year, number of implants, follow-up period, inclusion criteria, and whether survival or success was measured and how defined. Without this the page cannot answer its own headline question with a figure, which is its main commercial weakness. 2. **The reviewer's signed attestation** covering claims 9, 10 and 11, plus their register entry verified against the college's public register on the date of sign-off. 3. **Verification of the 1,400 figure** — the query or report it comes from, the date range, and confirmation of what counts as "placed." 4. **A compliance read** of the regional health advertising rules and the college code against the final draft, by a qualified adviser in your community. 5. **Consent documentation** for any patient feedback or images, if you later decide to use them — including what the consent covers and its expiry. 6. **Your own maintenance protocol in writing**, so the maintenance section describes what you actually do rather than a generic routine. --- *This output is not legal advice.
