Ten-year survival and chipping rates and clinical quality grading of zirconia-based fixed dental prostheses.

Objectives: To prospectively evaluate the clinical long-term outcome of 3- to 6-unit fixed dental prostheses (FDPs) made of hot isostatic pressed (HIP) zirconia frameworks, veneered with a synthetic sintering glass-ceramic.

Materials And Methods: A total of 27 different restorations were cemented in 21 patients. FDPs were examined with regard to biological and technical complications/failures.

Use of molecular indicators of inflammation to assess the biocompatibility of all-ceramic restorations.

Aim: The purpose of this in vivo study was quantification of inflammatory reaction to ceramic restorations made from lithium disilicate and zirconia by measurement of the concentration of indicators of inflammation in the gingival crevicular fluid (GCF).

Material And Methods: Patients out of three prospective cohort-studies investigating three different all-ceramic restoration materials for crowns and fixed dental prostheses were included. Patients needed an associated, unrestored tooth to serve as control.
