Technical Field
The invention relates to the technical field of tooth preparation, in particular to a model and a method for 3D printing of dental pulp of a tooth body.
Background
3D printing is a technique for building objects by layer-by-layer printing using bondable materials such as powdered metals or plastics based on digital model files.
The zirconium dioxide porcelain tooth has unique aesthetic property, has good light permeability, is close to real teeth, and has no light-blocking effect unlike other porcelain teeth. The color of the base crown of the zirconium dioxide ceramic is tooth white, so that the neck does not turn black, dark and green, and the problem that the metal ceramic crown is difficult to solve is solved. The zirconium dioxide full-ceramic tooth breaks through the limitation of the traditional ceramic tooth by the advantages of high mechanical strength, high hardness, high wear resistance, high corrosion resistance and the like, the dental crown is not supported by metal, and is completely made of biological ceramic, so that the zirconium dioxide full-ceramic tooth is far away from various electromagnetic interference in life and has no hidden trouble.
Hydroxyapatite is the main inorganic composition of human bone tissue, after being implanted into a body, calcium and phosphorus can be dissociated from the surface of the material and absorbed by the body tissue, and new tissue grows, and the material is healthy and bright white, can remove dental plaque, prevent tooth decay, refresh breath and improve the problem of gum, and meanwhile, researches prove that the finer the crystal grain of the hydroxyapatite is, the higher the bioactivity is.
The appearance characteristics of the teeth occluded with the false teeth are scanned by laser, and the required surface characteristics of the false teeth are printed out by 3D printing, so that the occlusion degree of the false teeth can be enhanced, the false teeth tightly attached to the dental bed of a human body can be processed, and the wear resistance, acid and alkali resistance and mechanical strength of the false teeth are improved.
At present, the traditional method for preparing the false tooth is generally hot-pressing molding after high-temperature melting, the method often involves manual mouth impression, and when the tray is taken out of the mouth of a patient, precision errors can be generated, so that the manufactured dental prosthesis is not fit, and the comfort of the patient and the wear resistance, the mechanical strength and the service life of the false tooth are affected.
