SafetyMemoDiscs (SMD) come fixed to certain instrument ranges. They are available separately, in bags or packed in SMD dispensers for greater ergonomy. When the recommendations, below are followed SMD enables optimal use of the instruments and control over metal fatigue. The SMD can be sterilized and remains attached to the instrument, thus ensuring that all the information on usage is saved.

For manual instruments, the SMD records the number of uses or how often they have been sterilized.

For rotary instruments, between one and four petals are removed from the flange after each treatment.

The number of petals remaining indicates which types of treatment are still possible :
