Zirconium oxide dental crown and preparation method thereof
The invention relates to the field of zirconium oxide dental crowns, in particular to a zirconium oxide dental crown and a preparation method thereof. The inner surface of the zirconium oxide dental crown is provided with a bonding surface; the bonding surface is formed by sintering a coating liquid coated on the inner surface of the dental crown; the coating liquid is prepared by mixing a mixture and a solvent according to a ratio of 1:(2-4); and the mixture is prepared from the following raw materials in percentage by weight: 30-40% of aluminium powder, 60%-70% of carbon elementary substance powder, and 0-3% of an additive. The rough and firm bonding surface is formed on the inner surface of the zirconium oxide dental crown, so that the bonding strength of the zirconium oxide dental crown and a to-be-repaired tooth is remarkably improved; and the falling probability of the dental crown is reduced.
本申请涉及涉及氧化锆牙冠领域，更具体地说，它涉及一种氧化锆牙冠及其制备方法。该氧化锆牙冠的内面设置有粘接面，粘接面由涂覆于牙冠内面的涂覆液烧结而成，涂覆液由混合料与溶剂按照1:(2～4)的比例混合制得，所述混合料由如下重量百分比的原料组成：铝粉：30～40%；碳单质粉末：60～70%；添加剂：0～3%。本申请通过在氧化锆牙冠内面形成粗糙且牢固的粘接面，促使氧化锆牙冠与待修复牙齿的粘接强度显著提高，从而降低了牙冠的脱落概率。
