The application discloses a preparation method of an interpenetrating phase
ceramic dental material and belongs to the technical field of biomedical materials. The application is based on the porous foam structure and cavity tissue of bird skeletons for
biomimetic design, two kinds of biomimetic bird
bone structures combining the characteristics of annular hyoid structures and cavity tissues are established, and according to the bird
skull cooperative damping mechanism, a
mortise and tenon structure with the characteristics of cooperative bearing and buffering is constructed, the structure has more excellent mechanical bearing performance and deformation stability compared with a traditional structure. The
zirconium oxide-hydrogel interpenetrating phase material prepared by a photo-crosslinking method, the composite design of the soft phase and the hard phase material not only significantly improves the
energy absorption characteristics of the material, but also effectively improves the
fracture toughness of the dental material. On this basis, a functional
coating is constructed on the surface of the material by using a
sol-gel
dip coating process, and the problems of insufficient
corrosion resistance and
wear resistance of the dental material in the oral environment are further solved.
