1. A registration and identification tool for a dental and/or cranio-maxillofacial surgical instrument, comprising:
a body having a first outer surface and a second outer surface substantially perpendicular to the first outer surface of the body,
a marker member which is optically detectable, the marker member being provided on the body,
a first recess in the body which extends from the first outer surface of the body into an inside of the body, thereby defining an extension direction of the first recess, wherein the first recess has a shape such that a lateral extension of the first recess decreases in the direction from the first outer surface of the body towards the inside of the body,
a second recess in the body, wherein the first and second recesses have different depths from one of the first and second outer surfaces of the body in a direction parallel to the other of the first and second outer surfaces of the body, and
a third recess in the body which extends from the second outer surface of the body into an inside of the body, thereby defining an extension direction of the third recess, wherein the third recess has a shape such that a lateral extension of the third recess decreases in the direction from the second outer surface of the body towards the inside of the body.
