25、opeThis International Standard specifies a method of dynamic testing of single post endosseous dental implants of the transmucosal type in combination with their premanufactured prosthetic components. It is most useful for comparing endosseous dental implants of different designs or sizes. This Inte

26、rnational Standard is not a test of the fundamental fatigue properties of the materials from which the endosseous implants and prosthetic components are made.This International Standard is not applicable to dental implants with endosseous lengths shorter than 8 mm nor to magnetic attachments.While t

27、his International Standard simulates the functional loading of an endosseous dental implant under “worst case” conditions, it is not applicable for predicting the in vivo performance of an endosseous dental implant or dental prosthesis, particularly if multiple endosseous dental implants are used fo

If the manufacturer intends the endosseous dental implant to be sterilized by the clinician prior to surgery, sterili

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

An endosseous dental implant component recommended by its manufacturer to be used in conjunction with components of another manufacturer shall

39、 be tested as assembled according to the recommending manufacturers statement. Where a multi-part device is assembled by means of screw joints, then these shall be used according to the manufacturers recommendations and shall be tightened to the manufacturers recommended torque using the equipment (

40、implant screwdriver, 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 testingIf a p

The choice of worst case shall be justified and documented. Guidance on how to choose the worst case is given i
