ISO/TS 13498:2011 establishes a method to determine the torsional yield strength and maximum torque of the implant body/connecting part joints of endosseous dental implant systems. This test is most appropriate for evaluating new types of joints and connecting parts, as well as new materials.

ISO/TS 13498:2011 provides a protocol for torsional loading of an implant body/connecting part joint. It is not applicable for predicting the in vivo performance of an endosseous dental implant system and it is not derived from observations of clinical failure.
