Abstract
The invention relates to a dental treatment instrument with which a dental handpiece (1), at its instrument end and/or at its hose end, is provided with unlocking planes (4a, 4b) which cooperate with correspondingly complementarily formed unlocking planes (5a, 5b) of a dental treatment instrument (2) or of a hose connection (3) of a supply hose. The treatment instrument (2) or the supply hose (3) can, because of the cooperating unlocking planes (4a, 4b; 5a, 5b), be released by simple turning of the treatment instrument (2) or of the supply hose (3) relative to the dental treatment instrument.
