A bite block that is inserted into a patient's mouth during an endoscopic diagnostic or surgical procedure that has a channel for receiving an endoscope or other surgical instrument through the patient's mouth and additional channels transmitting a gas to the patient and transmitting expired gas from the patient.

The invention is a device for use as a prop to hold the mouth open which consists essentially of a bite block with an elongated portion that is deflected and to provide a physiologically shaped elongated portion extends along the buccal border of the tongue to form a tongue depressor and light reflector as the bite block is held in position. The retaining arm, tongue guiding hole and the flange retain the patient's tongue in the bottom cavity of the patient's mouth.

An improved medical gas supply mask adapted to allow insertion of a broncoscope or endoscope into a patient's mouth without removing the mask. The mask's gas supply portal is located below the mouth instead of directly below the nose. The mask has an attached, typically extendable, tubular bite block that has an outer orifice on the outside of the mask. The surgeon can thus manipulate a scope tube or other instrument into the esophagus or trachea as desired while still providing oxygen to the patient. The mask includes small closed side-ports to receive items like a CO2 monitor tube and the like. Instruments up to approximately 4 cm may be inserted.

The invention relates to a method for preparing a complete denture closed impression from a novel edge trimming and shaping material.The method comprises the following steps that an initial impression is taken and filled, and an initial model is made; a temporary base tray and individual trays are made on the initial model; bite blocks are made on the temporary base tray and the individual trays, and trial biting is carried out to determine the upper and lower jaw position relation; the edge trimming and shaping material is bonded to the edge of the temporary base tray, the temporary base tray is led into the mouth of a patient, and the patient is guided to carry out initiative edge trimming and shaping.Inorganic filler is added into the edge trimming and shaping material and can improve the strength of the material; the inventor finds through practical use that the strength of an existing material is slightly poor, the shape maintaining effect is not good and slight deformation exists after the existing material is cooled to the room temperature, after deformation, the fitting degree of denture bases and the edge soft tissue thereof is likely to be decreased, and the edge sealing effect is weakened.
