A two-years clinical observation of all-ceramic restorations using Vita In-Ceram glass-infiltrated ceramic

Objective This paper observed the clinical effect of Vita In-Ceram glass-infiltrated cer amic restorations Methods A total of 194 restorations (124 ma x illary and 70 mandibular prostheses) made with Vita In-Ceram glass-infiltrated ceramic were examined in 45 patients. There were 165 anterior tooth crowns, 21 posterior tooth crowns, and 8 FPDs. Surface, color, anatomic form, and marginal integrity of restorations were assessed at 3 months, 6 months, 1 year and 2 year s after cementation with the California Dental Association (CDA) quality assessm ent evaluation system. Results It showed that the marginal fitness, color stability an d strength of crowns were considered to be satisfactory. Only 001% (two crowns ) were not acceptable. Two FPDs were not acceptable at 6-month visit, however, the anterior FPDs were considered to be satisfactory.Conclusion It is possible to construct excellent all-ceramic prostheses with the Vita In-Ceram glass-infiltrated cer amic system.
