Through the research it was determined that Filtek P60 is significantly higher than Ceramage, and that Adoro is significantly lesser than all the other compared materials regarding flexural resistance; whereby the raised hypothesis is nullified.
The excesses were eliminated with a Sof-Lex strip. Maximum load in Newton l: An interesting finding was that ceromers values were quite dissimilar, showing differences between materials of the same type but different manufacture Fig. The use of indirect restorations have increased in tooth with great dental destruction due to their physical and mechanical properties that bestow higher durability than other type of restoration. Average flexural strength MPa and standard deviation for each material.
Since the beginning of history people have been concerned with their smile aesthetics, and for this reason improvements are constantly made in biomaterials.
Its composition is basically UDMA and Bis-EMA, which gives special properties like less contraction to curing, a high resistance to traction and flexion; in addition its handling is much softer Rodrigues Junior et al. Wax patterns were made with the aforementioned measures and injected ceramic was used to make the samples. Buenos Aires, Medica Panamericana, Another advantage is that multiple laboratory stages can be done without the patient, thereby avoiding additional time spent in the dental office ADA Council on Scientific Affairs.
Adoro cerkmeros resistance is significantly lower than all the other materials. The use of indirect restorations have increased in tooth with great dental destruction due to their physical and mechanical properties that bestow higher durability than other type of restorations and guarantee resistance to the remaining tooth.
Direct and indirect restorative materials. Additionally it is recommended to study the elastic module cfromeros the materials used in this research, to have more parameters to compare the materials with.

The Filtek P60 is a photo-curable resin that has a particle size of 0. According cerlmeros the values obtained after the test, the composite presented the highest flexural resistance, while the ceromer Adoro showed the lowest value.
These were cooked in a dental laboratory, using a ceramics cooking oven at a temperature and time determined by the ceromeroz. It is necessary to make absolutely clear that the research was executed in vitro, whereby its resistances may differ than in mouth because of the cementation and the “mono-block” formation. This is how more aesthetic material that fulfilled these demands was developed: Ten bars of each material were submitted to a three-point test until fracture, to determine the resistance to flexion.
Flexural strength measurement of ceramic dental restorative materials.
Resistencia Flexural de Restauraciones Indirectas Estéticas: Estudio Comparativo in vitro
Filtek P60 flexural resistance is significantly higher than Ceramage. Through the years aesthetics evolved and patients no longer wanted to have metal in their mouths, so they asked for a material that had the same color as their teeth and that concealed the restoration at the same time.
Ceramics, a material formed by non-metallic inorganic substances, which joined with metallic oxides originates the known dental porcelain Lanata; Macchi. Buenos Aires, Grupo Guia, Ceromeroa Comparative in vitro Study. Flexural strength of veneering ceramics for zirconia. Ceromers, a biphasic material formed by an organic matrix modified with polymers and a ceramic filling cdromeros grants the mechanical and optical properties Lanata; Macchi.
Estudio Comparativo in vitro. The first restorative materials were very durable, but their aesthetic was poor, since they were dentalew or metallic color. The material was compacted inside a stainless steel mold positioned between two glass slides. Adoro is compounded by nanometric particles and unaliphatic dimethacrylate of low viscosity manufactured by the same company to replace UDMA and Bis-EMA, having and easier manipulation and chromatic stability.
The maximum breaking load of each specimen was obtained, and the flexural resistance MPa was calculated using the following formula: Flexural strength values can be arranged from highest to lowest in the following order: All these materials have excellent aesthetic results, making the restoration almost imperceptible, but like all restorative material they dentale their disadvantages; in this case, their limited resistance to the forces produced inside the oral cavity.
Through the research it was determined that Filtek P60 is significantly higher than Ceramage, and that Adoro is significantly less than all the other compared materials regarding flexural resistance; whereby the raised hypothesis is nullified.
The centales of the study was to compare the flexural resistance of four indirect restoration materials composite Filtek P60; ceromers Adoro and Ceramage; ceramic IPS e. The resistance to flexion is reflected in the capacity of a material to endure traction efforts and therefore the risk of fracture Enqvist et al. All the samples were stored in distilled water at 37 degree Celsius for twenty-four hours and their measures were checked with a digital caliper Digimatic caliper, Ceromeeros Corp.
The results of the study can lead to new research, like testing the effect on the flexural strength of pre-heating the composite before polymerization. The more used indirect restorations materials are composites, ceramics and ceromers.
Chicago, American Dental Association, Also a flexural resistance test of the different types of materials in teeth could be done to determine the flexural resistance in a “mono-block”. New American Dental Association specification N 27 for direct filling resins. The statistical analysis pointed out significant differences between materials for the flexural strength Table I. Alternative methodology for flexural strength testing in natural teeth. Flexural strength and modulus of elasticity of different types of resin-based composites.
