摘要

The stop device (3) has a shell with an inner cavity (5) of shape similar to that of a head (2) or neck of a contra-angle handpiece (6) for locking the shell on the head. An extension is provided in an axial direction of a canal instrument fixed in the head. The extension is terminated in its lower part by a ring performing a stop function, where length (L) of the extension determines the length of work of the instrument.
