Dentistry - Implants - Dynamic fatigue test for endosseous dental implants (ISO 14801:2007)
ISO 14801:2007 specifies a method of fatigue testing of single post endosseous dental implants of the transmucosal type and their premanufactured prosthetic components. It is most useful for comparing endosseous dental implants of different designs or sizes.
While it simulates the functional loading of an endosseous dental implant body and its premanufactured prosthetic components under “worst case” conditions, ISO 14801:2007 is not applicable for predicting the in vivo performance of an endosseous dental implant or prosthesis, particularly if multiple endosseous dental implants are used for a prosthesis.
Zahnheilkunde - Implantate - Dynamische Ermüdungsprüfung für enossale dentale Implantate (ISO 14801:2007)
Diese Internationale Norm legt ein Prüfverfahren für die Ermüdung von einpfostigen enossalen dentalen Implantaten vom transmukosalen Typ und für ihre vorgefertigten Implantataufbauten fest. Das Verfahren ist geeignet zum Vergleich von enossalen dentalen Implantaten mit unterschiedlichen Konstruktionen oder Größen.
Obwohl in dieser Internationalen Norm die funktionelle Belastung eines dentalen Implantatkörpers und seiner vorgefertigten Implantataufbauten unter den Bedingungen des „ungünstigsten Falls“ simuliert wird, sollte sie nicht dazu verwendet werden, die in vivo Leistungsfähigkeit eines enossalen dentalen Implantats oder eines Zahnersatzes vorauszusagen, insbesondere nicht für Anwendungen, bei denen mehr als ein Implantat als Zahnersatz verwendet wird.
Art dentaire - Implants - Essai de fatigue dynamique pour implants dentaires endosseux (ISO 14801:2007)
L'ISO 14801:2007 spécifie une méthode d'essai de fatigue des implants dentaires à un seul poste de type endosseux ou transmuqueux et de leurs éléments prothétiques préfabriqués. Elle est très utile pour comparer des implants dentaires de conception et de tailles différentes.
Même si l'ISO 14801:2007 simule la mise en charge fonctionnelle, dans les conditions les plus défavorables, de corps d'implants dentaires endosseux et de leurs éléments prothétiques préfabriqués, elle n'est pas applicable pour prévoir le fonctionnement d'un implant ou d'une prothèse dentaire in vivo, notamment lorsque la prothèse est constituée de plus d'un implant.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 14801 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 8, Dental
implants.
This second edition cancels and replaces the first edition (ISO 14801:2003) which has been technically
revised to include manufactured pre-angled connecting parts.
INTERNATIONAL STANDARD ISO 14801:2007(E)
Dentistry — Implants — Dynamic fatigue test for endosseous
dental implants
1 Scope
This International Standard specifies a method of fatigue testing of single post endosseous dental implants of
the transmucosal type and their premanufactured prosthetic components. It is most useful for comparing
endosseous dental implants of different designs or sizes.
While this International Standard simulates the functional loading of an endosseous dental implant body and
its premanufactured prosthetic components under “worst case” conditions, it is not applicable for predicting the
in vivo performance of an endosseous dental implant or prosthesis, particularly if more than one implant is
used for a prosthesis.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1942 and the following apply.
3.1
endosseous dental implant system
device that consists of integrated components including the ancillary instruments and specific equipment
necessary for the clinical and laboratory preparation and placement of the implant, and for the construction
and insertion of the dependent prosthesis
NOTE 1 In addition to providing resistance to displacement of a dental prosthesis, an endosseous dental implant may
be used as an anchorage for orthodontic appliances.
NOTE 2 An endosseous dental implant may consist of one or more parts.
NOTE 3 The term dental prosthesis includes crowns and fixed and removable prostheses.

3.2
load-cycle diagram
diagram summarising the fatigue properties of an endosseous dental implant by showing for each value of the
applied peak load the number of cycles endured by each specimen at the time of failure
See Annex A.
4 General Principles
4.1 Finished device testing
Testing shall be performed on specimens that are representative of the finished device (i.e., 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 (screw driver, 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.
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 and ISO 4965);
⎯ 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;
⎯ be capable of recording the number of loading cycles during the test.

5.2 Loading geometry
5.2.1 The loading force, F, (see Figures 1 and 2) of the testing machine shall be applied in such a way that:
⎯ no lateral constraint occurs;
⎯ the loading centre (Point C in Figures 1 and 2) is well-defined, such that the moment arm, y, can be
measured or calculated.
5.2.2 For dental implant systems that include no pre-angled connecting parts, these requirements will be
met by the test set-up shown schematically in Figure 1.

between the implant axis and the axis of the angled portion of the connecting part, 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 connecting part and the plane normal to the longitudinal axis of the implant and located 11 mm
(l in Figure 2) from the support level of the implant.
