Bionic enamel zirconia ceramic material block, dental prosthesis and preparation method
The invention relates to a bionic enamel zirconia ceramic material block, a dental prosthesis and a preparation method. The bionic enamel zirconia ceramic material block comprises a functional wearing layer; the functional wearing layer comprises zirconia and a stabilizer used for stabilizing the zirconia; the zirconia is formed by zirconia nano crystallites; intragranular defects are formed in the nano crystallites; the outer surface of the functional wearing layer is used for forming an occlusal surface; and the functional wearing layer is used for simulating the straight enamel rod layer of natural tooth enamel. According to the technical scheme disclosed by the invention, the situation that the dental prosthesis excessively abrades jaw teeth can be relieved; the obtained zirconia ceramic material block has the advantages of high strength, low hardness and low elastic modulus; the probability of breaking of the bionic enamel zirconia ceramic material block and the dental prosthesis is reduced; the service lives of the tooth prosthesis and the jaw teeth are prolonged; in addition, the appearance of the bionic enamel zirconia ceramic material block and the appearance of the dental prosthesis are very similar to the appearance of natural teeth; and the bionic enamel zirconia ceramic material block and the dental prosthesis have excellent light transmission, transparency and polishing degree.
本公开涉及一种仿生牙釉质氧化锆陶瓷材料块、牙修复体和制备方法，包括：功能磨耗层，功能磨耗层包括氧化锆和用于稳定氧化锆的稳定剂，氧化锆由氧化锆纳米雏晶形成，纳米雏晶内形成有内晶缺陷，功能磨耗层外表面用于形成咬合面，功能磨耗层用于模拟天然牙齿釉质的直釉柱层。通过本公开的技术方案，能缓解牙修复体对于对颌牙过度磨损的情况，得到的氧化锆陶瓷材料块兼备了高强度、低硬度、低弹性模量的优点，降低了仿生牙釉质氧化锆陶瓷材料块和牙修复体的出现折断的概率，有利于延长牙修复体和对颌牙的使用寿命，另外，上述仿生牙釉质氧化锆陶瓷材料块的外观和牙修复体的外观均与天然牙齿的外观非常相似，具备优良的透光性、透明度和抛光度。
