The procedure is especially useful for comparing dental implants of different designs, dimensions or configurations under defined laboratory conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The standard simulates functional loading under defined \u201cworst case\u201d conditions. It does not, however, predict the in vivo performance of a dental implant or dental prosthesis, particularly when several implants are used to support one prosthetic restoration. The test is also not intended to determine the fundamental fatigue properties of the implant materials themselves.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Typically, n=11 implants are tested up to a maximum number of 5 million cycles or 2 million cycles (polymeric samples). We can provide testing according to ISO 14801 in air as well as in fluid.<\/p>\n\n\n\n<div style=\"height:37px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>EXECUTIVE SUMMARY<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ISO 14801 is one of the key mechanical test methods for dental implant systems. The test evaluates how an implant assembly behaves under repeated compression-bending loading. The implant body, abutment, connecting screws and other relevant premanufactured prosthetic components are assembled according to the intended use and then loaded dynamically until failure occurs or until the defined number of cycles is reached.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The result is typically presented as a load-cycle diagram. This diagram shows the applied peak load and the number of cycles endured by each specimen. From this data, the maximum endured load and the corresponding bending moment can be determined for the tested configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Read more&#8230;<\/summary>\n<p class=\"wp-block-paragraph\"><strong>Purpose of the test<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The aim of ISO 14801 is to compare the fatigue behaviour of dental implant systems under reproducible laboratory conditions. The test setup represents an unfavourable loading situation and therefore supports the mechanical evaluation of implant designs, implant-abutment connections and prosthetic component assemblies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The method is relevant for endosseous dental implants with a transmucosal design and an endosseous length of at least 8 mm. According to the standard, the method is not applicable to dental implants with endosseous lengths shorter than 8 mm or to magnetic attachments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Finished device testing<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Testing is performed on specimens that are representative of the finished device. This means that the tested implant components should correspond to the device intended for marketing, including the relevant manufacturing processes and, where applicable, sterilization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the manufacturer specifies that the implant is to be sterilized by the clinician before surgery, the specimens are sterilized according to the manufacturer\u2019s instructions before testing. If there is evidence that the specified sterilization method has no significant effect on the properties of the tested materials, sterilization before testing is not required by the standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Assembly of multi-part implant systems<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For multi-part endosseous dental implants, the system is tested in the assembled condition intended for use. This includes implant bodies, abutments, connecting parts, abutment screws and implant connecting part screws where applicable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Screw joints are tightened according to the manufacturer\u2019s recommendations. The specified tightening sequence and torque are part of the test-relevant assembly conditions. If original instruments are not available, the standard allows the use of a device that provides the recommended torque within the specified tolerance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Worst-case configuration<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If an implant system is available in several dimensions or configurations, ISO 14801 requires testing under worst-case conditions within the recommended use. The selection of the tested configuration must be justified and documented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Worst-case selection can depend on implant diameter, implant length, cross-section at the embedding level, abutment geometry, angulation, connection design and the loading direction. For systems with rotationally non-symmetric components, the loading geometry must be selected so that the most critical compatible condition is tested and documented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Test environment and loading conditions<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The testing environment depends on the implant system. If corrosion fatigue is reported or expected, or if the system includes polymeric components, testing is performed in normal saline or another physiological medium. In such cases, the medium and specimen are kept at 37 \u00b0C +\/- 2 \u00b0C.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For other systems, testing may be performed in air at 20 \u00b0C +\/- 10 \u00b0C. The environment must be justified and reported.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The load is applied uniaxially and varies sinusoidally between the nominal peak load and 10% of that value. The loading frequency is limited to a maximum of 15 Hz. If testing is conducted in liquid media, the frequency is limited to 2 Hz or less.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Failure assessment<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Failure is defined broadly in ISO 14801. It includes material yielding, permanent deformation, loosening of the implant assembly or fracture of any implant component. The failure pattern should be described for the affected components, and, where possible, the failure process should be documented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Examples include screw fracture followed by abutment fracture, loosening of an assembly or fracture at a critical implant component. The report includes the test load, number of cycles to failure or termination, and the description and location of the critical failure point for each specimen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/details>","protected":false},"featured_media":0,"parent":0,"template":"","meta":{"_acf_changed":true,"_uag_custom_page_level_css":""},"dental-implant-taxonomy":[],"class_list":["post-2324","dental-implants","type-dental-implants","status-publish","hentry"],"acf":[],"uagb_featured_image_src":{"full":false,"thumbnail":false,"medium":false,"medium_large":false,"large":false,"1536x1536":false,"2048x2048":false,"trp-custom-language-flag":false},"uagb_author_info":{"display_name":"Theresa Kaddick","author_link":"https:\/\/endolab.org\/de\/author\/"},"uagb_comment_info":0,"uagb_excerpt":"ISO&nbsp;14801:&nbsp;Dentistry &#8211; Fatigue test for endosseous dental implants.
