Abstract
The full sintering process of zirconia has some extent of shrinkage and the custom abutment design should consider the pre-compensation volume of the shape. In this paper, we concentrated to reveal the asymmetric sintering characteristics. The circular profile of all six samples were measured using the three dimensional coordinate machine. After the full sintering process, the profiles were measured again. The roundness were compared to those of the original shapes and the percent of shrinkage were calculated. On the other hand, surface roughness was also investigated after the full sintering process. The final average surface roughness was improved by the sintering of the machined zirconia surface.
