1 Scope

This standard specifies the general principles of in vivo evaluation of implant bone formation activity for repair and replacement of bone tissue defects. Implants in this standard may be From natural or synthetic biological materials (biodegradable), or composite thereof. This standard describes the rat, rabbit, dog, pig, sheep and other species of animal models and the corresponding test procedures, as well as morphology, tissue biology Chemical and biomechanical analysis of the results of determination and evaluation methods. This standard applies to the repair and replacement of bone defect implants.
