Technical Field
The invention relates to the technical field of medical instruments, in particular to a 3D printing zirconia-based denture organic binder composition. The adhesive is used as a binder for 3D printing zirconia slurry, so that the slurry is rapidly molded, and the personalized zirconia false tooth is manufactured and applied to tooth defect repair.
Background
The false tooth is an important method applied to tooth defect repair, in recent years, ceramic teeth with high hardness and high wear resistance attract more and more attention, but the ceramic teeth cost is doubled due to the difficult processing characteristic of the ceramic. Compared with a metal denture, the zirconia-based ceramic denture based on 3D printing maintains the high hardness and high wear resistance of ceramic, and simultaneously solves the defect that the traditional ceramic denture is difficult to process. Through the 3D printing rapid prototyping technology, the individualized false tooth ceramic blank of the patient is directly printed by using the additive manufacturing method, the processing period is shortened, and the accuracy is improved.
However, for the zirconia-based ceramic false tooth based on 3D printing, the raw material is zirconia ceramic powder slurry, the slurry is formed by uniformly mixing zirconia ceramic powder and a binder in a solvent, the binder is an important component, and has the function of binding the zirconia ceramic powder to form a slurry with fluidity, after being extruded, the slurry is formed into a model with certain strength, and then the model is degreased to form a semi-finished product, the binder ensures that the slurry has good fluidity, the strength after the model is formed, and meanwhile, the binder requires degreasing efficiency, has low internal stress, and is safe and nontoxic.
