Integrated zirconia ceramic pile core crown and preparation method thereof
The invention discloses an integrated zirconia ceramic pile core crown. The method comprises the following steps: selecting the surface form of an inner cavity of a residual root as the appearance of a dental pile; the tooth nucleus adopts an umbrella cap structure, and the lower edge of the umbrella cap structure is completely matched with the residual part of the defective tooth body; the inner surface of the dental crown is attached to the outer surface of the tooth nucleus; the dental post is in seamless connection with the dental core, the dental core is in seamless connection with the dental crown, and the dental post, the dental core and the dental crown are integrally formed. The method has the advantages that repair failure caused by debonding of pegs, cores and crowns in clinical application can be effectively avoided; the preparation method provided by the invention provides a new solution for preparing the zirconium oxide ceramic pile core crown with the characteristics of individuation, small size and complex and fine structure.
本发明公开一种一体式氧化锆陶瓷桩核冠。本发明包括牙桩，选取残根内腔的表面形态作为牙桩的外形；牙核，牙核采用伞帽结构，伞帽结构的下边缘与缺损牙体的残留部位完全吻合；牙冠，牙冠内表面与牙核外表面贴合；所述牙桩与牙核、牙核与牙冠之间无缝连接，牙桩、牙核、牙冠一体成型。本发明优点是能有效规避临床应用中的桩、核、冠脱粘而导致得修复失败；本发明的制备方法，为制备具有个性化、小尺寸、复杂精细结构特点的氧化锆陶瓷桩核冠提供了新的解决方案。
