ISO/TS 13498 – Torsion testing of endosseous implants*

Q: What exactly is measured during torsion testing?

The test records parameters including torque and angle of rotation . These measurements are used to determine key mechanical properties such as torsional yield strength and maximum torque . The test specimen is also examined for deformation or damage after loading.

Q: What does maximum torque mean?

Maximum torque refers to the highest torsional load reached during testing . This value indicates the maximum torque the tested connection was able to withstand under the defined test conditions.

Q: How is the implant loaded during testing?

The torsional load is increased gradually and in a controlled manner . During the test, the testing machine records the relevant measurement data, allowing the behavior of the connection to be tracked throughout the entire test.

Q: Can the test also be performed on newly developed implant connections?

Yes. The test can also be used in the development and optimization of new implant connections . The resulting measurement data can be used, for example, to compare different designs, materials or design variants.

Q: Does ISO/TS 13498 test the entire dental implant?

The test focuses on the mechanical strength of the connection between the implant body and the connecting component under torsional loading. It should therefore not be considered a comprehensive assessment of all properties of a complete implant system.

Q: What is the difference between ISO/TS 13498 and ISO 14801?

ISO/TS 13498 evaluates the torsional strength of an implant connection , whereas ISO 14801 describes a dynamic fatigue test . Innoproof offers both tests. The appropriate test depends on the specific technical question being investigated.

How much torsional load can your dental implant connection withstand? As an accredited testing laboratory, Innoproof evaluates the mechanical strength of implant bodies and connecting components under defined torsional loading in accordance with ISO/TS 13498.

What Is Torsion Testing According to ISO/TS 13498?

Dental implants must withstand a wide range of mechanical stresses in everyday use. Chewing generates not only compressive and tensile forces but also torsional forces that can act on the connection between the implant body and the connecting component (abutment).

The purpose of torsion testing according to ISO/TS 13498 is to evaluate precisely this mechanical resistance.

Simply put, we apply a twisting force to the implant connection and measure how much load it can withstand. The load is increased in a controlled manner until the connection undergoes permanent deformation or reaches its maximum load-bearing limit.

The test provides objective measurement data showing how an implant connection performs under torsional loading. This is particularly relevant for the development, optimization and comparison of implant systems.

How Is Testing According to ISO/TS 13498 Performed?

Preparation of Test Specimens

The implant body and the corresponding connecting component are prepared and assembled in accordance with the specified test conditions.

Securing the Assembly in the Testing Machine

The assembled implant connection is securely mounted in the testing machine. This ensures that torsional loads can be applied to the connection in a controlled and reproducible manner.

Increasing and Measuring Torsional Load

The testing machine increases the applied torque in a controlled manner. During testing, parameters including torque and angle of rotation are continuously recorded. This makes it possible to track precisely how the connection behaves as the load increases.

Determining Load Limits

The measurement data is used to determine key parameters such as torsional yield strength and maximum torque. After loading, the test specimen is also examined for deformation or damage.

Evaluation and Documentation of Results

The measurement data and inspection results are evaluated and documented in a traceable test report.

Who Needs Testing According to ISO/TS 13498?

Torsion testing according to ISO/TS 13498 is particularly relevant for manufacturers and developers of dental implant systems, implant bodies and connecting components. It provides valuable mechanical data to support the development, optimization and evaluation of implant connections.

The test also provides an objective basis for evaluating and comparing existing and new connection concepts, materials and designs.

ISO/TS 13498 vs. ISO 14801 – What Is the Difference?

The appropriate test depends on the specific question being investigated and the implant system under evaluation. At Innoproof, we offer both tests and support you in determining which one is best suited to your product.

Both standards describe mechanical testing methods for dental implants, but they focus on different aspects.

While ISO/TS 13498 evaluates the torsional strength of the implant connection under twisting forces, ISO 14801 focuses on the dynamic load-bearing capacity of an implant under repeated mechanical loading.

ISO/TS 13498 Torsion Testing

Evaluates the connection between the implant body and connecting component under increasing torsional load.
Determines key parameters, including torsional yield strength and maximum torque.
Particularly relevant for evaluating and comparing implant connections.
This test is offered by Innoproof.

ISO 14801 Dynamic Fatigue Testing

Evaluates the implant under repeated dynamic loading.
Assesses implant performance under repeated mechanical stress.
Particularly suitable for comparing different implant designs under defined testing conditions.
This test is also offered by Innoproof.
