  • Publication number: 20190336255
    Abstract: A dental suction mirror for suctioning liquids and particles from an oral cavity includes a tubular hollow main body having inner and outer surfaces, a longitudinal axis, a connection opening for a tube, and a suction opening. The inner surface has a mirror that can be observed at least in some regions through the suction opening, and has a mirror surface and a rear side. The main body is configured as a single piece and includes, in its inner surface in the suction opening region, a mirror receptacle configured as a recess and in which the mirror is held in a locking manner. A method for producing a suction mirror includes at least manufacturing a base body with a mirror-accommodating portion and inserting the mirror by pressing it into the mirror-accommodating portion such that an elastic upper retaining shoulder is pressed outwards and contacts an upper face thereof.
