Good work machine to share the production process of denture processing

The goods that have passed the denture processing inspection are sorted by the master according to the technology of each employee. A layer of separating agent is applied to the surface of the abutment and immersed in wax water at a temperature of 85 to 95 degrees for one second to adhere a uniform layer of yellow wax to the surface of the abutment. After the yellow spicy is cooled, take it out and check for smoothness and cracks. After the completion, add a layer of the wax on the original yellow wax evenly, and the wax should be smooth. Then, a shoulder with a trapezoidal thickness of about 0.6 mm and a width of 1.0 to 1.2 mm is uniformly applied to the lingual side of the abutment. Recover the basic shape of the edentulous area with red wax and then cut back to make the position of the porcelain on each side of the tooth, about 1.5 to 1.8 mm. The wax type is required to have no sharp sharp corners. The thickness of the wax type is about 0.35 to 0.4 mm in the anterior teeth and about 0.4 to 0.45 mm in the thickness of the posterior teeth.

The steel tooth is added with red wax to the abutment of the abutment and the jaw tooth, and the anatomy of the tooth is restored. The shape of the tooth surface is carved with a scalpel, and the lingual side of the anterior teeth should be made. The overall bite is 0.1 to 0.2 mm, ensuring that one or two pieces of occlusal paper can be pulled out. The shape of the quadrilateral surface of the single crown should be accurate, and the surface of the wax type is smooth and free of phenanthrene. The connection of the bridge should be careful. In short, the wax type should have a certain thickness, and the thickness is uniform, and it is close to the abutment, and the surface is smooth and free of phenanthrene. Note that when adding wax, the wax should not be too high in temperature, just in order to avoid internal stress, resulting in wax deformation. Finally check the edges, bite, abut, etc.

Third, insert the casting road

Use a 2.5 mm thick wax strip to insert one or two wax strips of approximately 4 cm in length at the thickest and smoothest part of the wax pattern, at a 45 degree angle to the long axis of the tooth. When removing the wax type, it should be taken out in the opposite direction to the casting path. When taking the tooth, it should be gentle to prevent the wax type from deforming and cracking.

Fourth, embedding

Place the removed wax pattern in a circular shape on the upper 2/2 to 3/5 of the casting ring, which must be placed neatly, similar to the umbrella top. The distance between the wax type and the side of the rubber ring is 5 to 7 mm, and one ring cannot exceed 60 grams, that is, the total weight of the wax type must be less than 6 grams. Spray wax wash water to clean the wax type. Blow dry with air gun before embedding, pour the water and expanded water into the mixing cup in proportion, mix with the appropriate amount of embedding material, stir with a plaster knife for 8 to 10 seconds, then stir with a vacuum mixer for 40 to 60 seconds. After that, pour the mixed embedding material into the casting ring at a constant speed, and use an oscillator to assist in embedding. Pay attention to the bubbles in the embedded material and the proportions are appropriate. It is embedded in proportion to the weight of the wax. For example, if the wax type weighs 5 grams, it needs to be mixed with 300-350 grams of embedding powder and 70-84 ml of expanded water.

Five, denture processing quality inspection shipment

The master will sort out the dental molds, check again if there are any spare parts in the design list, whether it is complete, confirm the signature, and then send it to the quality inspection department for inspection and transfer to the car gold department.
