A Three-Year Retrospective Study on Survival of Ceramic-Veneered Zirconia (Y-TZP) Fixed Dental Prostheses Performed in Private Practices

Table 6

Life table analysis of zirconia fixed dental prostheses (FDPs). Cumulative Survival Rate (CSR).

Period (years)	Examined FDPs	Lost to follow-up		CSR (%)	Standard error
FDP cementation	184	0	0	100
1 year	165	16	3	98.1	1.1
2 year	150	13	2	96.7	1.4
3 year	132	16	2	95.2	1.8
Total	132	45	7	95.2

zirconia FDP that remained in situ over the full observation period and only displaying minor modifications that did or did not require intervention was regarded as survival.
