A head for a dental contra-angle having an operating shaft is coupled to the operating shaft in the vicinity of the bend of the contra-angle. The head is produced principally from a synthetic material and comprises an element for fastening the head onto the contra-angle, a pinion engaging a drive shaft associated with the head, and a support for receiving a tool and for locking the tool in the head. These various elements are designed so that the head can be sterilized or disposed of after use.
