Abstract

The invention relates to the technical field of the dental department and discloses a method for detecting internal defects of zirconium oxide double-layer all-ceramic repair body decorative ceramic.The method comprises the following steps: (1) performing micro-CT scanning: performing micro-CT scanning on a zirconium oxide double-layer all-ceramic repair body to acquire a two-dimensional image after scanning and converting the two-dimensional image into dicom data; and (2) performing three-dimensional modeling: importing the dicom data in the step (1) into processing software to perform three-dimensional modeling and analysis to acquire three-dimensional shape of air hole defects in the zirconium oxide double-layer all-ceramic repair body decorative ceramic to obtain data of air hole defects in the zirconium oxide double-layer all-ceramic repair body decorative ceramic. The air hole defects in the zirconium oxide double-layer all-ceramic repair body decorative ceramic can be detectedunder the condition of not damaging the zirconium oxide double-layer all-ceramic repair body, and crucial effect in clinical research on repair body collapsed ceramic is achieved.

Description

technical field [0001] The invention relates to the technical field of dentistry, in particular to a method for detecting internal defects of zirconia double-layer all-ceramic restorations. Background technique [0002] The fabrication defects inside the porcelain of zirconia double-layer all-ceramic restorations are an important reason for its high clinical chipping rate. However, not all defects in ceramic materials will lead to chipping failure of the restoration. ). Therefore, it is of great clinical significance to clarify the characteristics of the pores in the veneer of zirconia double-layer all-ceramic restorations and to explore the characteristics of the defects that easily lead to the failure of the restorations. [0003] In the prior art, researches on the failure behavior of zirconia double-layer all-ceramic restorations mostly use fractography analysis and theoretical formula calculations to illustrate the defect characteristics that cause ceramic collapse. C...
