| Outline of Final Research Achievements |
During the 2 year follow-up period, denture framework fracture was found for zirconia denture group, and the survival rate resulted to be 50%. We suggested that a risk of the zirconia frameworks fracture is high.
We successfully developed zirconia framework for partial dentures, which were designed and processed by fully digital workflow, applied it clinically. All aspects of the patient’s satisfaction and OHRQoL with the zirconia denture tended to improve.
