Technical Field
The invention relates to the technical field of auxiliary learning equipment for oral cavity, in particular to a double-layer resin tooth for preparing training of oral cavity teeth.
Background
The resin tooth is made of methyl methacrylate, has moderate hardness, is similar to natural teeth in shape and color, is not easy to crack, is well combined with a base material, and is very convenient to grind, change and polish. The color is yellow, and numbers 1 to 6 are slightly red, and the colors are light to dark according to the color sequence; the resin tooth filling has moderate hardness, has the shape and color similar to those of natural teeth, is not easy to break, and is well combined with the base material. The traditional Chinese medicine composition is widely applied in clinic and becomes the love of patients with tooth defects and decayed teeth; therefore, the most studied in the study of stomatology is resin teeth; dental restoration is an oral clinical medical course containing multidisciplinary knowledge, theory and practice are required to be tightly combined, dental preparation is very important and main content in early stage teaching of fixed restoration, and is the most commonly used basic clinical technology in restoration clinic, but students often find various problems in the dental preparation process in early stage practice teaching and clinical teaching, and the students have good knowledge of theory and standard, but cannot be well reflected in actual operation. At present, resin teeth are commonly used for replacing natural teeth in the tooth preparation teaching training process, the resin teeth for tooth preparation are of a single-layer structure, namely the materials, the textures and the colors of the resin teeth are the same from inside to outside, students judge and evaluate the preparation quantity and the preparation form in the tooth preparation process, and the resin teeth are difficult to master for beginners. In order to solve the problem that students are difficult to accurately judge and evaluate the preparation quantity and the preparation form in the process of tooth preparation, the technical scheme that resin teeth for tooth preparation and an indication female die are combined is adopted to perform tooth preparation in the process of tooth preparation teaching training; the resin teeth adopted by the method are of a single-layer structure, namely the materials, the textures and the colors of the resin teeth are the same from inside to outside, and meanwhile, the silicone rubber is used for indicating the female die to display the preparation quantity, so that the more accurate preparation quantity can be obtained.
