Abstract

Introduction. The differences in the mechanical properties of ceramic and resin-based materials raise the question of which material can perform better in the long run.

Objectives. Evaluate the flexural strength and color stability of different indirect aesthetic restorative materials.

Methods. The selected materials were Filtek™ Z250 XT (3M ESPE), Ceramage (SHOFU Dental), VITA VM®LC y VITA ENAMIC® (VITA Zahnfabrik), IPS e.max® (Ivoclar-Vivadent) y Zolid FX (Amann Girrbach AG). The Flexural Strength test (n = 10) was carried out, using a mechanical testing machine. Color readings (n = 5) were measured using a VITA Easyshade V® spectrophotometer.

Results. All ceramic materials showed better mechanical performance (p< 0,001). The color stability results show that Ceramage, IPS e.max® and Zolid FX, showed a statistically significant difference (p ≤ 0.002) with Filtek Z250 XT, VITA VM®LC and VITA ENAMIC®.

Conclusions. Some indirect aesthetic materials with polymers in their composition are presented as a valid alternative for indirect restorations, presenting acceptable mechanical performance and colorimetric stability.
