The preparation method comprises the following steps:

1. an impression of the patient's upper jaw was made using a silicone impression material.

Note that:

the patient's labial frenulum and palate are presented intact and clear on the maxillary impression.

2. The maxillary model was perfused.

2.1 slowly adding the Helish gypsum powder into a rubber bowl filled with a proper amount of water, uniformly stirring by using a stirring knife, vibrating for several times, and discharging air bubbles. A small amount of mixed gypsum powder is taken by a mixing knife and placed on the upper part of the palatal top or the lingual side of the impression, so that the gypsum powder flows into the dental crown part of the impression from one end and fills the whole impression gradually, and air bubbles escape at the same time. The addition was continued until the desired thickness was reached.

2.2 after a period of time, mixing gypsum to pour the base, wherein the base is parallel to the tray and has a certain thickness, and the width exceeds the edge of the impression by 3 mm.

2.3 after the plaster model has dried, the model is separated from the impression.

Note that:

the impression material and the gypsum are mixed in proper proportion and are uniformly mixed.

When the mold is filled, the mold is filled and vibrated at the same time, so that air bubbles are avoided.

The mold is cast with sufficient thickness and edge extension.

3. And (6) trimming the model.

3.1 use model finisher to trim the base of the mandible parallel to the HE plane to a thickness of 1/3-1/2 of the vestibular sulcus height of the cuspid.

3.2 the posterior wall of the maxilla is trimmed perpendicular to the floor and midline of the arch, approximately 1/2 tooth widths from the last molar.

3.3 the maxillary model bottom was trimmed to be level with the plane and the ground.

3.4 the side walls of the modified maxilla were parallel to the buccal cusps of the premolars and molars.

3.5 the maxillary anterior wall is trimmed to cuspate between the central incisors.

3.6 trimming the short chuck wall to be vertical to the bisector of the included angle of the back wall and the side wall.

3.7 finishing the maxillary model.

4. And (3) a film pressing method and a film pressing step.

4.1 put the upper jaw model on the flat plate of the negative pressure film pressing machine, heat the transparent soft diaphragm with the thickness of 2mm, press down when the diaphragm is heated to be in a drop shape, and vacuumize.

4.2 after the diaphragm is completely cooled, taking out the diaphragm from the model, trimming the diaphragm by using special scissors, reserving the diaphragm edge of the oral vestibule to the position 1mm away from the vestibular groove, reserving the diaphragm at the lingual side to the position 1-1.5 cm below the gum, and keeping the whole shape of the diaphragm in the general shape of a dental arch.

4.3 put the trimmed membrane back on the mold.

4.4 put the model on the plate of the negative pressure film pressing machine again, heat the soft diaphragm with the thickness of 2mm, press the film. When the membrane is heated to be in a water drop shape, the membrane is required to be heated for about 1 minute and 20 seconds at this time, and the heating button is turned off when the membrane is to be in a concave state, so that the membrane is not required to be immediately lowered for vacuumizing. And slowly pressing down when the diaphragm stretches to contact the upper jaw incisor. When the diaphragm covers the palate part of the oral cavity, the two layers of materials at the rear edge of the palate part are compacted by a clean wax knife, and are bonded by utilizing the self-adhesive property of the EVA material, so that air is wrapped into the two layers of materials. (simply, there is an air interlayer between two layers of EVA material).

4.5 trimming the protective denture base by using special scissors to trim labial frenulum and buccal frenulum, and keeping the oral vestibule area and palate as much as possible. The distance between the lowest edge of the diaphragm of the oral cavity vestibule and the vestibular sulcus is 1mm, the diaphragm on the middle incisor tongue side is reserved to be 1-1.5 cm below the gum, and the tail end of the protective denture generally covers the first molar. However, for better protective function, a patient who is not sensitive to the reaction of the protective denture can cover the most rear edge of the dentition so that the dentition is completely wrapped by the protective denture.

4.6 use the craftsman to polish the cell-phone fast and repair the protection denture fixing device, grind the edge of the diaphragm thin with the carborundum car needle, pay special attention to the repair of the frenulum of lip frenulum cheek and turning over of mucosa. And symmetrically grinding vent holes with the width of about 0.2mm at the sealing position of the two layers of materials at the rear part of the air bag by using a grinding mobile phone. (prevent the gasbag from bursting out when the stress is too large suddenly, the air in the gasbag can be discharged through the vent holes on both sides when the stress is too large).

4.7 polishing the polished edge of the membrane (the rotating speed of the machine needle is required to be less than 10000 r/min). In order to make the edge of the film smoother and not to cause abrasion to the oral mucosa, the manufactured protective denture can be put back on the model, and the edge of the film is blown back and forth by a hot air blower (in order to avoid the deformation of the film caused by heating, the film does not need to stay for too long time on the same part). After the film is completely cooled after blowing, the film is taken off from the model.

4.8 after the preparation, the membrane is disinfected by a conventional disinfectant.

4.9 try on the patient's mouth and guide the patient to protect the cautionary matters that the denture base used, carry out oral hygiene propaganda and teach.
