D.MATE series is a device designed to allow dentists to perform independent treatment without assistance from suction work.
Therefore, it is recommended that the dentist use it mainly for the first month after purchase.

Generally, it takes about two weeks to get used to it, and it takes about a month to become proficient and fully understand the advantages of the equipment.
After that, if you teach the assistant staff little by little and try to use them, you can use them all well.

This is because, if you let the staff use it first without the guidance of the dentist from the beginning, the staff may have difficulty using it.
