Dentures like real teeth, new material dentures, could replace porcelain teeth.

The new denture material has a micro-structure similar to that of a natural shell, with zirconia arranged in parallel in a layer or tightly stacked in the form of a "brick wall" in which the voids are filled with resinThe new denture material retains the excellent biocompatibility, corrosion resistance and aesthetic effect of zirconia ceramic, and has a certain plastic deformation ability and unique dynamic energy consumption characteristics, that is, the dentures can consume the energy applied by external forces through viscous elastic deformation when forced, thus playing a role in protecting the tooth bed and grinding teeththe hardness and mold of traditional zirconium oxide ceramic dentures are much higher than that of human teeth, when people have such dentures, they will significantly accelerate the wear of normal teeth in the jaw and contact on both sidesIn the experiment of new denture material and tooth-to-grinding, the material has a lower coefficient of friction than zirconium oxide ceramics, which can significantly reduce the wear of the tooth teeth on the human body normal teethIn particular, the fracture toughness of the new denture material is higher than that of all the denture materials reported, and its bionic structure plays an effective role in blocking the expansion of the crack by promoting crack deflection and preventing the crack openingin addition,, the new denture material is easier to mechanically process than zirconium oxide whole porcelain teeth, especially the use of computer-aided design and manufacturing (CAD/CAM) method can be produced in hospitals for patients, changed the existing zirconium oxide whole porcelain dentures can only be processed in a "privately customized" way, thus achieving batch supply, significantly reducing the preparation and processing costs of the dentures and shorten the patient's waiting timeLiu Zengqian pointed out that the new bionic compound denture material is expected to replace the current widely used zirconia full porcelain dentures, can significantly improve the use of dentures and extend their service life, with considerable application prospects and market potential, the research team is currently conducting further research on fatigue performance, coloring and biocompatibility under simulated cyclic bite conditions of the new denture material, and exploring clinical applications in cooperation with hospitals.
