Definition
On this page, “short” means a length of at most 6 mm within the same implant line — not a quality judgement. CLM-009
Short · clear · evidence-based
KUS kurz und simple
Short dental implants: shorter lengths within the same implant line.
Possibly also less bone grafting.
Within one implant line, the same model may be available in different lengths — for example 6, 8 or more millimetres. On KUS, “short” means at most 6 millimetres. The word describes length and is not, by itself, a quality judgement. CLM-009
When conditions are suitable, the shorter length may fit the existing bone. Extra grafting may then be avoided entirely or kept smaller.
If a larger procedure worries you, it is worth asking about this option. Whether it is suitable for you is decided after examination. A short implant is still placed surgically.
If dental treatment causes strong fear, see questions that help you prepare the conversation.

In brief
Survival: orientation values with limits
In some analyses, no statistically significant survival difference was shown for the stated comparison. That does not prove equivalence. Ten-year data remain thinner and are not a uniform direct comparison. Details and sources: section 05 “Comparison”. CLM-002 · CLM-004 · CLM-005 · CLM-007
Survival is not the same as treatment success. Studies do not replace an individual decision. Do not mix comparison arms (>6 · ≥8.5 · ≥10 mm).
01 · Introduction
Short answer
Capability
With limited bone height, they can in selected cases be an alternative to longer implants plus grafting / sinus lift. CLM-001 · SRC-002
Comparison
Everyday language: longer implants from about 8 mm. Studies: exactly ≥8.5 mm or ≥10 mm — do not mix arms.
02 · Medical classification
Medical classification
Short implants are not a “miracle option” of their own, but one choice in implant planning — when bone height is limited and grafting is to be avoided or reduced.
Clinically it is a weighing of options: Is the available bone height sufficient for an implant of at most 6 mm with reliable anchorage and sensible prosthodontics — or is longer from about 8 mm (possibly with grafting) the clearer rationale? The decision follows findings, imaging, and individual planning — not a marketing category.
When the question arises
Typically with limited residual bone height in the posterior region, after tooth loss with height loss, or when a sinus lift / vertical augmentation is perceived as a major extra procedure.
What is also assessed
Bone height and width, soft tissue, occlusion and load, freedom from inflammation, general health, hygiene/follow-up capacity, and the planned restoration (single tooth to segment).
What studies help — and where they do not
Survival comparisons (e.g. ≤6 vs ≥8.5 mm without augmentation) help set expectations. They do not replace an indication. Do not mix arms; survival ≠ treatment success. CLM-007 · CLM-010
Limits of classification here
This page explains and situates. It does not diagnose, recommend an implant system, or replace information given at the practice.
Questions that aid understanding
- Is my bone height enough for 6 mm — and what alternative exists without major grafting?
- Which comparison length is meant in my case (everyday from about 8 mm vs study arm ≥8.5 / ≥10 mm)?
- What changes in surgical extent, healing time, prosthodontics, and follow-up?
- Which risks and uncertainties remain — even with “good” survival figures?
Medical classification means: making options and limits understandable —
not placating fear and not creating pressure. For clarification on page content see
Contact; for examination a practice of your choice
(note on possible providers: Treating practices).
03 · Motive
When the procedure or dental treatment causes fear
Concern about major grafting or a larger procedure is a common reason to read this page. The word “short” can add uncertainty — as if shorter length were automatically a compromise.
Name this concern at the appointment. Ask how the procedure is planned, where pauses are possible, which anaesthesia is intended, and which support fits you.
This page does not present anyone as especially suited because of dental fear, and it does not promise pain-free or risk-free treatment. It helps you take questions with you.
04 · Capabilities
What 6 mm implants can do
Can — in selected cases
- Use existing bone height over a shorter distance
- Avoid vertical augmentation
- In the posterior maxilla, be an alternative to sinus lift
- Reduce surgical extent when planning supports it
Cannot categorically
- Mean “no surgery”
- Rule out every risk
- Transfer statements from 6 mm to 4/5 mm
- Replace soft tissue, inflammation control, or follow-up care
05 · Comparison
Short (6 mm) vs. longer (from about 8 mm)
From the patient’s side, often the question: Is 6 mm enough — or do I need longer from about 8 mm including grafting? For citability we keep the study arms separate.
| Reader question | Study comparison | Cautious statement |
|---|---|---|
| Short vs. somewhat longer | ≤6 mm vs >6 mm | 1–5 years: survival similar in an ITI/CLR basis; difference not significant CLM-002 · SRC-003 · ≤6 vs >6 mm |
| Short vs. from about 8 mm | ≤6 mm vs ≥8.5 mm | Non-augmented bone: no significant survival difference (moderate evidence) CLM-004 · SRC-004 · ≤6 vs ≥8.5 mm |
| Short vs. clearly longer | ≤6 mm vs ≥10 mm | Selected 5-year scenarios similar; others unclear CLM-003 · SRC-002 · ≤6 vs ≥10 mm |
≥8 mm in everyday language is close to the study arm ≥8.5 mm — we state the study threshold correctly.
Short ≤6 mm
Longer (from about 8 mm / study arms)
- Comparison arms differ: >6 · ≥8.5 · ≥10 mm
- With enough bone often plannable without extra grafting
- 10-year data: pooled single-group survival is orienting; in four paired RCTs short-implant 10-year survival was statistically lower (RR 0.920 / 0.943) — no blanket equality claim CLM-005 · SRC-005
Summary (study terms): For survival in selected short-/medium-term comparisons often no significant difference — especially ≤6 mm vs ≥8.5 mm without augmentation. That does not mean “always equally good”. Ten-year data call for caution: pooled single-group values and the paired RCT comparison must be read separately. Survival ≠ treatment success. CLM-005 · CLM-007
When prefer 6 mm?
- Bone height limited, width/anchorage okay
- Crown positionable correctly
- Major grafting would clearly increase fear/burden
- Hygiene and follow-up feasible
When prefer longer?
- Enough bone without major extra effort
- Prosthodontics clearly favors more length
- “Short at any cost” would be unreasonable
06 · Evidence
Evidence — citable and honest
What is well supported?
In selected situations, 6 mm implants can avoid vertical augmentation or a sinus lift — depending on anatomy and planning. CLM-001 · SRC-002
One to five years
ITI/CLR basis: mean survival 96% (≤6 mm) vs 98% (>6 mm); difference not significant. Not automatically a ≥8 mm comparison. CLM-002 · SRC-003 · arm ≤6 vs >6 mm
Ravidà 2024: ≤6 mm vs ≥10 mm — in selected scenarios similar 5-year survival rates. CLM-003 · SRC-002 · arm ≤6 vs ≥10 mm
Camps-Font 2022: ≤6 mm vs ≥8.5 mm (non-augmented) — no significant survival difference. Next robust arm for the patient comparison “from about 8 mm”. CLM-004 · SRC-004 · arm ≤6 vs ≥8.5 mm
Ten years
Lin 2026: pooled 10-year survival of short implants about 91.2 % (patient) / 93.7 % (implant) — single-group pool, abstract level. In four directly comparing RCTs the 10-year survival of short implants was statistically lower than that of longer implants (≥10 mm; RR 0.920 patient / 0.943 implant). That is not a judgement about every patient or every implant length; method limits remain. CLM-005 · CLM-006 · SRC-005 · ≤6 mm vs ≥10 mm in those RCTs
Implant survival is not the same as treatment success, freedom from complaints, or prosthesis survival.

07 · In depth
Bone grafting — stages of invasiveness
Common procedures, ascending from low to high. Short implants aim to avoid higher stages where possible — not to make grafting always unnecessary.
-
1
Socket / ridge preservation
Protect ridge volume after tooth extraction. Low invasiveness.
-
2
Small lateral augmentation / GBR
Particulate grafting laterally. Low to moderate.
-
3
Internal sinus floor elevation
Transcrestal, often combined with implant placement. Moderate.
-
4
External sinus floor elevation
Window technique. Moderate to high — often the fear trigger.
-
5
Vertical augmentation / onlay block
Height gain with higher burden. High.
-
6
Extensive ridge reconstructions
Large reconstructions / distraction or similar. Very high.
Individual indication decides — not the price list.
08 · Timing
Timing: immediate · early · late
Immediate
Implant in the same session as tooth extraction. Immediate loading is a different protocol — not automatically included.
Early
After soft-tissue healing, typically weeks to a few months — before the ridge is fully remodeled.
Late
After largely completed bone healing, often several months later. More waiting time, sometimes more plannable.
What studies reasonably support
Immediate is not automatically better or worse — inflammation, bone availability, primary stability, and prosthodontics are decisive.
“Early” and “late” are planning terms, not a quality guarantee.
09 · Prosthodontics
Prosthetic restoration concepts
After implant length: How is the jaw restored?
Segmented multi-unit bridges — example edentulous maxilla
16–14
13–11
21–23
24–26
Analogous in the mandible. Multi-unit abutments = interface for screw-retained segments. Repair and hygiene stay more manageable.
| Concept | Idea | Note |
|---|---|---|
| Segmented multi-unit | Several bridge sections | Illustrative with some providers: divisible, maintainable — not advertising |
| All-on-4 / All-on-X | Fixed full-arch restoration on few implants | Reviews often report high implant survival rates, but also frequent prosthetic complications (e.g. acrylic fracture, screw loosening) and maintenance needs. No robust meta-claim that “All-on is inferior to segmented multi-unit restoration”. |
| Bar overdenture | Bar + removable prosthesis | Proven option with suitable indication |
| Telescopic prosthesis | Double crowns, removable | Chosen by some providers when posterior bone is lacking — not a recommendation, not advertising |
Illustrative practice context (not advertising): Some providers describe segmented multi-unit restoration;
with lacking posterior bone often telescopic. All-on remains an option — not as the standard there, because segmentation can be more maintainable and divisible.
Studies do not show All-on as categorically “worse”, but as a
concept with often good survival figures and a relevant complication/follow-up profile.
This is not advertising and not a recommendation of individual practices.
10 · Orientation
Dental tourism
All-on packages are often marketed internationally as fast, low-cost full restorations. That can be worthwhile if you are regularly abroad anyway and can reliably attend follow-up there.
Otherwise caution:
- Check the credibility of practice, implant system, and follow-up care
- Complications often arise only months later — then accessibility matters
- Legal protection and warranty are often limited across borders
A lower price does not replace plannable follow-up care.
11 · Process
Process example (illustrative)
Illustrative example path as described by some providers who may have experience with short implants, when the indication supports it: analog where clear, digital where useful — without marketing promises, without advertising, and without a forced pathway for every anatomy.
- Surgery day: Sanitation + implant placement preferably in one stage; bone improvement only as needed.
- After about 12–16 weeks: Uncovery + scan; soft tissue shaped if needed.
- After one further week: 3D simulation and bite registration.
- After about 2 further weeks: Final restoration seated (often zirconia). Digital scan often instead of impression.
Digital + analog
Scan instead of impression material where possible. Clear appointment chain. Segmented multi-unit or telescopic restoration.
Not marketing first
Technique follows indication. No healing promise, no forced pathway for every anatomy.

15 · FAQ
Frequently asked questions
Is a short implant different or worse?
On KUS, “short” means length: at most 6 millimetres. Within one implant line, the same model may be available in different lengths. That is not a quality judgement and not proof of the same clinical results.
Can bone grafting be avoided or reduced?
When conditions are suitable, the shorter length may fit the existing bone. Extra grafting may then be avoided entirely or kept smaller. Whether that applies to you is decided after examination.
Is it still surgery?
Yes. A short implant is still placed surgically. “Short” does not mean “no procedure”.
How do I raise dental fear at the practice?
Name the fear at the appointment. Ask about the planned steps, possible pauses, anaesthesia, and support that fits you. This page does not present anyone as especially suited because of dental fear, and it does not promise pain-free treatment.
What alternatives exist when there is little bone?
Besides a short implant, grafting may still be needed — sometimes smaller than first expected. Sometimes another prosthetic plan is more suitable, for example one that does not place a posterior implant. The practice classifies this after examination.
What examination is needed?
Individual diagnostics at the practice. Which images or procedures are needed in a given case is decided there — this page does not make them a blanket requirement.
How long does a short implant last compared with a longer one?
In some analyses, no statistically significant difference was shown for the stated comparison. That does not prove equivalence and is not an individual prognosis. Implant survival is not the same as a fully uneventful treatment result. Arms must not be mixed (≤6 vs >6 / ≥8.5 / ≥10 mm). CLM-011 · CLM-004 · CLM-007
Does a 6 mm implant always avoid sinus lift?
No. In selected cases in the posterior maxilla it can be an alternative. Not for every anatomy and not automatically for lengths shorter than 6 mm. See also section 07 “Bone grafting”. CLM-001 · CLM-010 · SRC-002
When is a longer implant preferable?
A longer implant may be considered when enough bone is present and it can be placed safely and sensibly without a major extra procedure. That is not a rule for every case.
Why not All-on as the standard?
Because segmented multi-unit and — when posterior bone is lacking — telescopic restorations are described by some providers as a maintainable approach. All-on can be indicated; as a pure low-cost/immediate package (including in dental tourism) it should be scrutinized especially critically. This is illustrative context — not advertising and not a recommendation of individual practices. See also section 09 “Prosthodontics”.
Does treatment abroad make sense?
Before you decide, clarify the whole pathway: Where do the check-ups take place? Who makes the prosthesis, who places it, and where? Whom do you contact if problems arise after you return, and how do you reach that person or practice? Which services and costs are agreed in writing? The answers help you judge whether the pathway fits your situation.
What do the percentage figures (e.g. 96%, 91.2%) mean for my individual case?
These figures are averages from study cohorts, not an individual prognosis. They describe how many implants in a given study were still present after a given period (survival) — not whether treatment was comfortable or functionally successful in an individual case. Anatomy, bone quality, follow-up and individual risk factors shape personal outcomes and are not captured by averages. CLM-007
Closing
Is 6 mm justifiable in the long term — or is longer from about 8 mm the better rationale? Only then: grafting stage, timing, prosthodontics.
How we classify evidence
Each factual statement on this page has a claim ID (e.g. CLM-004) and a source ID (e.g. SRC-004) that can be looked up in the source register. Two status labels show the review stage: verified_abstract — checked against the cited abstract; pending / pending fulltext — full text not yet finally reviewed; such statements do not appear here as quotable facts. This system does not replace a systematic guideline appraisal. It shows the review stage of each statement.
