Abstract:

Objective    To investigate the clinical effect of Vita In-Ceram Zirconia glass-infiltrated ceramic restorations，and to provide a reference for clinical application. Methods    A total of 81 restorations （61 maxillary and 20 mandibular prostheses） made with Vita In-Ceram Zirconia glass-infiltrated ceramic were examined in 59 patients. There were 44 anterior tooth crowns， 27 posterior tooth crowns， 4 anterior fixed bridges and 6 posterior fixed bridges. Surface， color， anatomic form， and marginal integrity of restorations were assessed at 3 months， 6 months， 1 year and 2 years after cementation with the California Dental Association （CDA） quality assessment evaluation system. Results    It showed that the marginal fitness， color stability and strength of crowns were considered to be satisfactory. Only 0.030 % （two crowns） were not acceptable. One posterior fixed bridge were not acceptable at 3-month visit；however，the fixed bridge were considered to be satisfactory. Conclusion    With strict control of indications，it is possible to construct excellent all-ceramic prostheses with the Vita In-Ceram Zirconia glass-infiltrated ceramic system.
