| Increased mechanical properties in composite resins [15, 18] | Increased mechanical properties of the resin composite in the semidirect composite resin veneers, excellent strength, and adhesion to the tooth structure [18]
Improvement in physical and mechanical properties of the restorative material through complementary polymerization [10, 11] | Brittle, prone to fracture, and can induce wear with opposing tooth’s surface [22]
More resistant than direct resin composite and semidirect composite resin veneers [27] |
|
| More economical than semidirect composite resin veneers and ceramic veneers | More expensive than direct resin composite, and less than ceramic | Expensive |
|
| Depends on the clinical skills | Better contouring of proximal contacts and occlusal contacts, improved wear resistance, and reduced polymerization contraction when compared to direct composite resin veneers [12] | Better finishing and final polishing [18] |

The final color appearance of a composite restoration depends on the composition of the composite itself, the composite’s thickness according to the substrate’s color underneath it, pigment amount, and type and layering technique [37]
The color stability after aging depends on the composition of the resin composite itself [37] | Better optical properties than direct resin composite due to the types of light-curing resin composite [10, 11]
The color stability after aging appears to be more stable than direct resin composite due to the improvement of the physical and mechanical properties of the materials by reducing the thermal expansion coefficient and polymerization shrinkage, providing radiopacity, and improving the handling and esthetics of materials [17, 18]. The shrinkage of the material has been continuously improved over time [17, 18] | The optical parameters, surface texture, and translucency were affected by chemical aging on the glass ceramics Vita Mark II (Vita Zahnfabrik, Germany) and IPS Empress CAD (Ivoclar Vivadent AG, Liechtenstein), lithium disilicate-based ceramics e.max CAD (Ivoclar Vivadent AG, Liechtenstein), Vita Suprinity (Vita Zahnfabrik, Germany), zirconia-based ceramic IPS e.max: ZirCAD LT (Ivoclar Vivadent AG, Liechtenstein), and IPS e.max ZirCAD MT Multi (Ivoclar Vivadent AG, Liechtenstein) [37]
The self-adhesive dual-cure cement showed color stability comparable to the total-etch light-cure resin cement for the cementation of IPS e.max (Ivoclar Vivadent, AG, Liechtenstein) ceramic veneers. The color stability of both cements was superior to that of the self-adhesive self-cure cement [38]
Ceramic and resin-cement systems affected the color stability after the aging of ceramic veneers [38] |
