DIN Standards Committee Materials Testing

Overview

In the year 2016 more than 1 million dental implants were inserted in Germany. In order to ensure that these implants last for many years in the patient's mouth, standardized test methods are very important, for example for long-term mechanical loading (for chewing simulation). Nobody wants their implant to break after 6 years due to material fatigue when chewing. This International Standard has been prepared by ISO/TC 106/SC 8/WG 4 "Mechanical testing" (secretariat: ANSI, USA) together with CEN/TC 55 "Dentistry" (secretariat: DIN). The DIN-NADENT Working Committee NA 014-00-21 AA "Dental implants" is responsible. The standard specifies a test method for the fatigue of single-post endosseous dental implants of the transmucosal type and for their prefabricated abutments. The method is suitable for comparing endosseous dental implants with different designs or sizes. This standard is a test standard with which the permanent load of an implant system (that is, implant plus abutment) can be tested. Critical factors in selecting the worst case for a series of implants with different abutments are a) implant: thickness, length, cross-section at embedment height 3 mm below the shoulder (for conical implants), b) abutment: height of the abutment and orientation/notching/index. A decision diagram for determining the worst case is included in Annex B. Because this examination is relatively expensive and takes a long time (at least 6 weeks), the following applies: By choosing the worst case scenario wisely, unnecessary tests can be avoided and considerable costs can be saved. This standard contains the crucial information to this end. On the other hand, this test shall be carried out for the approval of an implant and/or abutment. The standard ensures that the test report is also accepted by the approval bodies if the correct combination (worst-case) has actually been tested in accordance with DIN EN ISO 14801.
