Dental zirconia ceramic pile core and manufacturing method thereof
The invention discloses a dental zirconia ceramic pile core and a manufacturing method thereof. The dental zirconia ceramic pile core comprises a personalized integrated pile core body, the pile core body is composed of a pile body (1) fixedly bonded in a dental pulp cavity and a core body (2) exposed out of the dental pulp cavity, a core bottom platform (3) is arranged at the bottom of the core body, and a retention protrusion (4) is arranged at the top of the pile body and connected with the core bottom platform. According to the dental zirconia ceramic pile core and the manufacturing method thereof, stable retention can be ensured, and the risks of pile breakage and tooth root fracture caused by excessive lateral force transmitted to the pile tip due to radial micro-movement of the core under the action of lateral occlusal force are avoided.
本发明公开了一种牙科氧化锆陶瓷桩核及其制作方法，包括个性化设计的一体化桩核，所述桩核由粘固于牙髓腔内的桩（1）和暴露在牙髓腔外的核（2）两部分组成，所述核的底部设有核底平台（3），所述桩的顶部设有固位突(4)，核底平台与固位突相连。本发明能够确保稳定固位，避免因核在侧向咬合力作用下产生径向微移动而给桩尖传递过大的侧向力，导致桩断裂和牙根折裂的风险。
