Materials: thermoplastic copolymer Quantity: 2 pieces Size (Application): 6,3 m X 5 cm Softens and shrinks when hit by hot water 【Characteristic】: 1. Good shape stability. After long immersion in boiling water, the prosthesis will not deform or shrink. So it can't be used. 2. High transparency. 3. Good thermoplastic. Compared with similar products, thermoplastics has obvious advantages, especially suitable for home use, and the eraser line is very clear. 4. It can be formed many times. Due to the inaccurate determination of water temperature and soaking time, the shaping effect of the dental tray is often unsatisfactory. Even if the molding is weak, this product can be re-formed in hot water at 80-90, which is not found in other products. 【How to use】： 1. Practice wearing braces: Wear braces on your upper gums and use suction to drain air between your braces and gums so that braces can cover a whole row of teeth. Surface. Tips: Practice twice, this is an important process when creating braces. Do the same with the lower prosthesis. 2. Soften the tooth tray: pour water at a temperature of 80-90 into a container with a flat bottom. The depth of water is sufficient to submerge the dental tray and leave the handle off the surface of the water. Soak the dental tray in water for 5-7 seconds and remove it. Tips: At the moment, the prosthesis is very soft, so the diving time should not be too long. It should be soft and elongated when the prosthesis is raised and slightly deformed. 3. Perform tooth support: Raise the tooth support, carefully and quickly place the tooth support on the gums and continue the suction method described in step 1. The fingers firmly press the surface of the denture binder and tooth to thin it, and the tip of the tongue pulls the denture and the inner surface of the tooth. Tips: Be quick and be careful not to bite hard. The prosthesis is a little hot, but it won't hurt. 4. Trimming the dental tray: After pressing with your fingers for 10 to 15 seconds, remove the dental tray and rinse it with water. Cut off excess material with scissors along the gum line (the line between teeth and gums) embossed on the prosthesis, then cut off the handle. 5. 1. Try to avoid smoking so as not to "stain" the surface of the teeth. 2. Be sure to rinse your mouth after eating to get rid of bacteria and pigments that may stick over time. 3. Insist on brushing your teeth at least twice a day in the morning and evening. 4. Use nici dental properly and do not leave room where dirt will get into the space between your teeth. 5. Brush your teeth regularly and do a “big cleaning” of your teeth. Thermoplastic dental trays have two effects.
