Dentistry - Implants - Dynamic loading test for endosseous dental implants (ISO 14801:2016)
ISO 14801:2016 specifies a method of dynamic testing of single post endosseous dental implants of the transmucosal type in combination with their premanufactured prosthetic components. It is most useful for comparing endosseous dental implants of different designs or sizes. This International Standard is not a test of the fundamental fatigue properties of the materials from which the endosseous implants and prosthetic components are made.
This International Standard is not applicable to dental implants with endosseous lengths shorter than 8 mm nor to magnetic attachments.
While ISO 14801:2016 simulates the functional loading of an endosseous dental implant under "worst case" conditions, it is not applicable for predicting the in vivo performance of an endosseous dental implant or dental prosthesis, particularly if multiple endosseous dental implants are used for a dental prosthesis.

Overview
EN ISO 14801:2016 (ISO 14801:2016) - Dentistry - Implants - Dynamic loading test for endosseous dental implants - specifies a standardized method for dynamic (fatigue) testing of single‑post endosseous dental implants of the transmucosal type together with their premanufactured prosthetic components. The standard is intended for comparative laboratory evaluation of implant designs and sizes under simulated “worst‑case” functional loading. It is not a substitute for in vivo performance prediction and does not measure fundamental material fatigue properties.
Key topics and technical requirements
- Scope limits
- Applies to single post endosseous implants (transmucosal type) assembled with manufacturer’s prosthetic components.
- Not applicable to implants with endosseous length < 8 mm or to magnetic attachments.
- Worst‑case testing
- When multiple sizes/configurations exist, the worst‑case condition must be selected, justified and documented (Annex B guidance).
- Finished device testing
- Test finished devices representative of marketed products; sterilize prior to testing only if intended in clinical use or if sterilization affects properties.
- Multi‑part assembly
- Multi‑part implants tested as assembled; screw joints tightened per manufacturer’s recommended torque (use instruments provided or within ±5% of recommended torque).
- Testing machine & accuracy
- Machine must apply prescribed loads and frequencies, monitor max/min loads and cycles, detect failure, and have force error ≤ ±5% at maximum load (per ISO 7500‑1).
- Loading geometry
- Loading applied with no lateral constraint; moment arm must be measurable.
- For straight abutments: central implant axis clamped at 30° ± 2° to loading direction.
- For angulated abutments: clamping angle adjusted to simulate a 10° under‑correction.
- Test procedure variants
- Includes cyclic dynamic loading, recording load‑cycle diagrams (Annex A) and an alternative staircase method to determine endurance limits.
- Reporting
- Requires detailed reporting of specimen preparation, loading geometry, machine settings, cycles to failure and justification of worst‑case choices.
Applications & who uses it
- Comparative laboratory evaluation of dental implant designs, geometries and prosthetic connections.
- Used by: dental implant manufacturers, R&D engineers, test laboratories, regulatory affairs teams and notified bodies assessing implant mechanical performance and design robustness.
- Useful for product development, pre‑market validation and technical documentation supporting regulatory submissions (mechanical endurance evidence).

4 General principles
4.1 Finished device testing
Testing shall be performed on specimens that are representative of the finished device (i.e. implant
components that have undergone the same manufacturing process and sterilization as the device
that is to be marketed). If the manufacturer intends the endosseous dental implant to be sterilized
by the clinician prior to surgery, sterilization shall be carried out as specified in the manufacturer’s
instructions for use before testing. However, if there is evidence that the specified sterilization method
has no significant effect on the properties of all the materials of the specimens being tested, then
sterilization is not necessary prior to testing.
4.2 Multi-part endosseous dental implants
A multi-part endosseous dental implant shall be tested as assembled according to its intended use. An
endosseous dental implant component recommended by its manufacturer to be used in conjunction
with components of another manufacturer shall be tested as assembled according to the recommending
manufacturer’s statement. Where a multi-part device is assembled by means of screw joints, then
these shall be used according to the manufacturer’s recommendations and shall be tightened to the
manufacturer’s recommended torque using the equipment (implant screwdriver, torque wrench) which
is provided together with the implant system or using a device that provides torque within ±5 % of
the recommended value if no original instruments are available. The tightening sequence shall be as
recommended by the manufacturer.
4.3 Worst-case testing
If a part of the endosseous dental implant system is available in various dimensions and/or
configurations, testing shall be carried out for the worst-case conditions within the recommended use.
The choice of worst case shall be justified and documented. Guidance on how to choose the worst case
is given in Annex B.

5 Test methods
5.1 Testing machine
The testing machine shall
— be capable of applying the prescribed load with an error not exceeding ±5 % at maximum load (in
accordance with ISO 7500-1),
— be capable of applying the load at the prescribed frequency,
— include instrumentation to monitor the values of maximum and minimum loads and loading
frequency and to detect failure of the specimen, and
— be capable of recording the number of loading cycles during the test.
5.2 Loading geometry
5.2.1 The loading force (see Figure 1 and Figure 2, arrow F) of the testing machine shall be applied in
such a way that
— no lateral constraint occurs,
— the position of the intersection of the loading axis (Line AB) with the axis of the endosseous dental
implant (Line DE), is well-defined, such that the moment arm (y) can be measured or calculated (see
Figure 1 and Figure 2).
ISO 14801:2016(E)
5.2.2 An endosseous dental implant from a system that includes only straight implant abutments shall
be clamped such that its central longitudinal axis makes a 30° ± 2° angle with the loading direction of the
testing machine (see Figure 1).

than the angle between the central longitudinal axis of the implant and the central longitudinal axis of
the angled-portion of the abutment, designated as α in Figure 2.
This represents a simulated undercorrection of 10°. The loading method shall be the same as that
shown in Figure 1. The loading centre shall be located at the intersection of the central longitudinal axis
of the free end of the abutment and the plane normal to the longitudinal axis of the implant and located

5.2.4 The loading force (F) of the testing machine shall be applied through a deformation resistant
loading member with a hemispherical contact surface for load transfer, attached to or placed over the
free end of the implant abutment.
The yield strength and the hardness of the loading member should be higher than that of the member
that is used to apply the load. The loading centre, which is the centre of the hemisphere, shall be on the
central longitudinal axis of the endosseous dental implant or, for endosseous dental implant systems
which include angulated implant abutments, shall be on the central longitudinal axis of the free end of
the abutment.

The SIST EN ISO 14801:2017 standard provides a comprehensive framework for the dynamic testing of single post endosseous dental implants with a focus on those of the transmucosal type and their premanufactured prosthetic components. This standard is pivotal in setting a consistent methodology for evaluating the dynamic loading capabilities of various endosseous dental implant designs, which is essential for comparison across different products in the dental implant market. One of the key strengths of this standard lies in its ability to simulate "worst case" loading conditions, which enhances the relevance of the testing process for assessing the durability and load-bearing capacity of implants under extreme conditions. However, it is crucial to note that while this dynamic loading test provides insights into implant performance, it does not function as a method for determining the fundamental fatigue properties of the materials used in dental implants and prosthetic components. Furthermore, SIST EN ISO 14801:2017 specifically outlines the limitations of its application, clearly stating that it does not pertain to dental implants that have endosseous lengths shorter than 8 mm or to magnetic attachments. This demarcation ensures that the standard is applied only to relevant implant types, enhancing the accuracy and reliability of outcomes obtained through the testing. While the standard effectively assists in evaluating single endosseous implants, it should be understood that it does not predict the in vivo performance of implants when multiple endosseous implants are utilized for a prosthesis. This realization is crucial for practitioners and researchers when relying on the findings from the dynamic loading tests, emphasizing the distinction between laboratory test conditions and actual clinical performance. Overall, the SIST EN ISO 14801:2017 standard is a significant contribution to the field of dentistry, particularly for professionals involved in the development, comparison, and clinical application of endosseous dental implants. Its established protocols for dynamic testing ensure that comparisons between different implant designs can be made with confidence, promoting advances in dental implant technology and patient care.
La norme SIST EN ISO 14801:2017 présente un cadre essentiel pour la mise en œuvre de tests dynamiques sur les implants dentaires endos-sseux de type transmucosal. Son champ d'application se concentre spécifiquement sur la méthode de test dynamique pour les implants dentaires à poste unique, en association avec leurs composants prothétiques préfabriqués. Cela permet une comparaison efficace des implants dentaires endosseux de différents designs ou tailles, ce qui est crucial pour le domaine dentaire. Parmi les points forts de cette norme, on note son approche innovante qui simule des conditions de charge fonctionnelle dans un scénario de "pire cas". Cela en fait un outil précieux pour évaluer la résistance et la durabilité des implants dentaires, contribuant ainsi à assurer leur fiabilité dans un cadre clinique. Cependant, il est important de souligner que cette norme ne vise pas à tester les propriétés fondamentales en fatigue des matériaux utilisés pour la fabrication des implants et des composants prothétiques. Il convient aussi de préciser que la norme SIST EN ISO 14801:2017 ne s'applique pas aux implants dentaires présentant des longueurs endosseuses inférieures à 8 mm, ni aux attaches magnétiques, ce qui en délimite le champ d'application. Bien que cette norme fournisse un cadre pour le test dynamique, elle n'est pas conçue pour prédire les performances in vivo des implants dentaires ou des prothèses dentaires, en particulier lorsque plusieurs implants endosseux sont intégrés dans une prothèse. En somme, la norme SIST EN ISO 14801:2017 est un document de référence qui contribue à la standardisation des tests d’implants dentaires, offrant un moyen fiable pour évaluer et comparer les performances des implants dentaires endosseux dans un cadre contrôlé. Son introduction devrait être hautement pertinente pour les praticiens et fabricants d'implants dentaires souhaitant garantir des produits de qualité dans le domaine de l'odontologie.
Die SIST EN ISO 14801:2017 bietet eine präzise und strukturierte Methode zur dynamischen Prüfung von einzelnen Transmukosalen dentalen Implantaten mit spezifischen protesischen Komponenten. Der Standard fokussiert sich auf ein effektives Testverfahren, das sich bestens für den Vergleich von endosseösen dentalen Implantaten verschiedener Designs oder Größen eignet. Hierbei wird ein realistisches Szenario simuliert, bei dem das Implantat unter Worst-Case-Bedingungen belastet wird. Ein bedeutender Vorteil dieser Norm ist ihre Fähigkeit, die Wiederholbarkeit und Zuverlässigkeit von Testergebnissen zu gewährleisten, was für die Validierung von Implantatdesigns von zentraler Bedeutung ist. Sie stellt sicher, dass die getesteten Implantate unter vergleichbaren Bedingungen geprüft werden, was die Interpretation der Resultate erheblich erleichtert und die Innovationsprozesse in der Zahnmedizin unterstützt. Es ist wichtig zu beachten, dass dieser Standard nicht die grundlegenden Ermüdungseigenschaften der Materialien testet, aus denen die endosseösen Implantate und protesischen Komponenten hergestellt sind. Das nicht anwendbare Verhältnis zu Implantaten mit einer endosseösen Länge von weniger als 8 mm sowie zu magnetischen Halterungen ist klar definiert, was Missverständnisse in der Anwendung des Standards vermeidet. Die Relevanz der SIST EN ISO 14801:2017 im Bereich der Zahnmedizin liegt in ihrer spezifischen Ausrichtung auf endosseöse Implantate und deren funktionale Belastungen. Obwohl diese Norm nicht für die Vorhersage des in vivo Verhaltens von Implantaten oder Zahnprothesen geeignet ist, ist ihr Beitrag zur vergleichenden Bewertung von Implantatdesigns und -leistungen von großer Bedeutung. Die Norm ist damit ein unverzichtbares Werkzeug für Entwickler und Anwender im Bereich der dentalen Implantologie.
SIST EN ISO 14801:2017 표준은 치과 분야에서 세계적으로 인정받는 기준으로, 특히 전치부 또는 후치부에 적합한 임플란트를 평가하는 데 중요한 역할을 합니다. 이 표준은 주로 전막형 단발치유 임플란트와 그에 부착된 사전 제작된 보철 부품의 동적 하중 시험 방법을 규정하고 있습니다. 표준의 주요 강점은 서로 다른 설계나 크기의 임플란트를 비교할 수 있는 유용한 방법을 제공한다는 점입니다. 특히, 다양한 디자인을 갖는 임플란트의 성능을 더 쉽게 평가하고 분석할 수 있도록 도와줍니다. 이러한 비교 기능은 치과 의사들이 적합한 임플란트를 선택하는 데 큰 도움이 됩니다. 하지만 이 표준은 임플란트의 기본 피로 특성을 시험하는 것이 아니라는 점에서 주의가 필요합니다. 또한, 8mm 이하의 내골 길이를 가진 임플란트나 자석 부착장치에는 적용되지 않기 때문에, 그 범위를 명확히 인식할 필요가 있습니다. 이는 해당 분야에서 신뢰할 수 있는 데이터 또는 기술적 기준을 제공하기 위한 초석이 됩니다. ISO 14801:2016이 최악의 경우 상황에서 임플란트의 기능적 하중을 시뮬레이션하는 데 유용하지만, 실제 생체 내 성능을 예측하는 데는 한계가 있다는 점 역시 강조되어야 합니다. 특히, 여러 개의 내골 임플란트를 사용할 경우 임플란트 또는 보철물의 실제 성능과는 다른 결과를 도출할 수 있음을 유념해야 합니다. 이러한 점들을 고려할 때, SIST EN ISO 14801:2017 표준은 치과 임플란트 기술의 발전에 기여하며, 임플란트의 안전성과 효과성을 평가하는 데 있어 매우 중요한 기준으로 자리 잡고 있습니다.
SIST EN ISO 14801:2017は、歯科用インプラントに関する国際標準であり、特にトランスムカソル型の単一ポストエンドオッシーインプラントの動的ロードテストを規定しています。この標準は、異なる設計やサイズのエンドオッシーインプラントを比較するための有用な手段を提供します。 この文書の強みは、動的テストの方法論が明確に定義されており、インプラントとその製造プロステティックコンポーネントの一体的な評価が可能である点です。また、「最悪の条件」を考慮したテストが行われるため、現実の使用条件下でのインプラントの挙動を模擬することができます。このアプローチにより、製品設計の改善や品質管理に寄与する結果が期待されます。 しかしながら、SIST EN ISO 14801:2017は、エンドオッシー長が8 mm未満のインプラントや磁気アタッチメントには適用できないため、これらのケースにおいては別途評価が必要です。また、エンドオッシーインプラントや歯科用プロステシスのin vivoパフォーマンスの予測には使用できないことも留意すべきです。 この文書は、歯科医療分野におけるインプラントの設計と評価において重要な役割を果たし、特に異なるインプラントの比較を行う際に貴重な情報を提供する国際標準としての relevanceを持っています。
