Abstract
A dental teaching device has a dummy head displaceably mounted, within predetermined ranges of movement, on a holder so that the head can be adjusted to any desired position for a practice dental treatment. The holder has a curved socket in which a curved rear portion of the head is slidably received. The curved socket is shielded from exposure to contaminant material by the dummy head thereabove, for all positions of adjustment of the head relative to the holder. An opening in the curved rear portion of the head is defined by a rim which constitutes a limit stop engageable with a stop element secured to the holder and extending into the interior of the head through the opening.
