Objectives:
To analyze survival and complication rates for anterior and premolar laminate-veneers out of different ceramic materials (feldspathic, leucite-reinforced glass-ceramic [LRGC], lithium-disilicate [LDS] and zirconia).
Material And Methods:
A systematic literature search was conducted across multiple databases for clinical studies on ceramic laminate-veneers with a minimum-follow-up of ≥ 1 year. The date of last search was on February 19, 2024. Survival, technical, esthetic and biological events were assessed for different laminate-veneer materials at three observation periods (short- [1-3 years], mid- [4-6 years] and long-term [≥ 7 years]).
Results:
Twenty-nine studies were included. Meta-analysis revealed a pooled survival-rate of 96.13% for feldspathic, 93.70% for LRGC and 96.81% for LDS at 10.4 years. No difference was found between materials. Complication rates (technical/esthetic/biological) were as follows: Feldspathic: 41.48%/19.64%/6.51%; LRGC: 29.87%/17.89%/4.4%; LDS: 6.1%/1.9%/0.45% at 10.4 years. Zirconia showed a 100% survival-rate with no complications at 2.6 years. No long-term data was available for zirconia.
Conclusions:
Feldspathic, LRGC and LDS laminate-veneers showed high survival-rates at long-term observation. LDS slightly outperforms feldspathic and LRGC laminate-veneers with lower long-term complication rates. More studies providing long-term data on zirconia laminate-veneers are needed.
Clinical Significance:
Ceramic laminate-veneers are a reliable treatment option. LDS may be preferred as a restorative material for long-term success.
