一种牙科用氧化锆陶瓷修复体
摘要：
本发明公开了一种牙科用氧化锆陶瓷修复体，所述牙科用氧化锆陶瓷修复体由以下重量份的原料组成：氧化锆：6～17；氧化铝：0.5～1.0；陶瓷粉：10～25；淀粉：25～48；氧化钇：3～12；分散剂：0.5～2.5；水溶性粘结剂：1.5～3；金银花提取液：0.3～2；着色剂：0.5～5。采用本发明得到的牙科用氧化锆陶瓷修复体具有较高的硬度，其成分中加入了分散剂和金银花提取液，解决了全瓷材料易碎、光泽度低、展色性差、透明度低以及抗菌性差的问题，且选用的材料来源广，对人体健康；本发明牙科用氧化锆陶瓷修复体成分中加入了着色剂，满足了现代社会个性化的社会需求，具有广阔的市场前景。
摘要（英）：

The invention discloses a dental zirconia ceramic restoration. The dental zirconia ceramic restoration comprises the following raw materials by weight: 6 to 17 parts of zirconia, 0.5 to 1.0 part of alumina, 10 to 25 parts of ceramic powder, 25 to 48 parts of starch, 3 to 12 parts of yttrium oxide, 0.5 to 2.5 parts of a dispersing agent, 1.5 to 3 parts of a water-soluble binder, 0.3 to 2 parts of honeysuckle flower extract and 0.5 to 5 parts of a coloring agent. The dental zirconia ceramic restoration obtained in the invention has high hardness; since the dispersing agent and honeysuckle flower extract are used as the components of the restoration, the problems of frangibility, low glossiness, poor color contrast performance, low transparency and poor antibacterial performance of an all-ceramic material are overcome; the used raw materials are widely available and beneficial for human health; and since the coloring agent is used as a component of the dental zirconia ceramic restoration, individual needs of modern society are met and wide market prospects are obtained.
