“…Autores como Ferrario et al (2004), encontraron que las fuerzas oclusales de un solo diente en hombres adultos sanos fueron de 150 y 140 N para los incisivos centrales y laterales respectivamente. Gibbs et al (1981) declararon que las cargas oclusales son de 263 N durante la masticación normal.…”

Odontostomat., 10(2):185-195, 2016. RESUMEN:Los pilares híbridos individualizados en disilicato de litio, permiten adaptarse a la forma y el perfil de emergencia obtenido después de la temporalización de los implantes, presentando buenas características ópticas y determinando la posibilidad de una cementación adhesiva. El propósito del estudio fue evaluar la resistencia a la fractura de pilares individualizados en disilicato de litio en comparación con los pilares en circona-ytria tetragonal (Y-TZP), ambos cementados en una base de titanio PGTB (Ti base) mediante un estudio experimental in vitro. Se confeccionaron 10 pilares: 5 como grupo control, elaborados en Y-TZP, mediante el sistema Ceramill multi-X Amanngirrbach ® y 5 pilares híbridos en disilicato de litio mediante la técnica de inyección (IPS e.max ® press abutment solution, Ivoclar Vivadent) como grupo experimental. Cada pilar se precargó a un implante con un torque de 30 N/cm 2 . Todas las coronas se fabricaron en disilicato de litio (técnica monolítica) y se cementaron usando cemento resinoso de curado dual (RelyX ® U200, 3M ESPE). La medición de la resistencia a la fractura se realizó en una maquina universal de pruebas (instron ® ), modelo 2519-105. La resistencia a la fractura fue almacenada y evaluada utilizando la prueba paramétrica t-student. Para evaluar las fracturas incipientes y clasificar el tipo de falla se usó un microscopio óptico Carl Zeiss. los valores de resistencia promedio para los pilares de disilicato de litio fueron de 655,5 N y para los de circona 780,52 N con una desviación estándar de 145,76 N y 147,71 N, respectivamente. Ambos tipos de pilares evidenciaron buen comportamiento ante la prueba de resistencia a la fractura; sin embargo, se requieren más estudios que evalúen este tipo de pilares.PALABRAS CLAVE: cerámicas, porcelana dental, disilicato de litio, pilar híbrido, resistencia a la fractura.

“…The maximum bite force and single tooth bite force in the premolar region have been reported to be 246-398 N 13) and 179-291 N 14) respectively. The failure loads obtained for all the groups in this study were greater than these values.…”

Effect of fiber-premixed indirect resin composite substructure on fracture resistance of MOD composite inlays adhered with two different adhesive resin cements

This study evaluated the effect of a fiber-premixed indirect resin composite (FMC) substructure on the fracture resistance of mesialocclusal-distal (MOD) indirect composite restorations adhered to extracted human upper premolars. The teeth received a standardized MOD cavity preparation, and indirect composite inlays were fabricated with or without using the FMC. Inlays were cemented into the cavity preparations using either Super-Bond C&B or Panavia F2.0. A total of 28 specimens, namely seven specimens for four groups, were thus fabricated. Failure load and failure energy were determined after thermocycling (4-60°C for 5,000 cycles). In terms of failure load, no significant differences were found among the four groups. In terms of failure energy, FMC substructure exerted a significantly favorable effect on Super-Bond C&B-bonded group but a negative one on Panavia F2.0-bonded group. In conclusion, the failure energy of the group using FMC substructure and which was adhered using Super-Bond C&B was significantly higher than the other groups.

“…Ferrario et al 35) studied single-tooth bite forces in healthy young adults, and they reported results of 250 and 290 N for the first and second premolars, respectively, in men. Greater bite forces must be expected in subjects with functional disturbances, such as bruxism 36) .…”

The purpose of this study was to evaluate the influence of the number of proximal contacts and fiber-reinforced composite (FRC) post insertion on the fracture behavior of endodontically treated premolars with class II (MOD) cavities and direct composite restorations. Forty-eight single-rooted human premolars were endodontically treated and prepared with standardized MOD (mesio-occluso-distal) cavities. One-half of the teeth additionally received FRC-posts (DT Light SL) luted with Panavia F resin cement. All of the specimens were restored with direct composite restorations, and the teeth were embedded in proximal contact with either zero, one or two adjacent tooth-replicas. Eight sound premolars served as control. After thermomechanical ageing, the samples were loaded until fracture at an angle of 30°. The sound teeth showed the highest mean fracture load. Teeth with one or two proximal contacts and FRC-posts showed only statistically insignificantly lower values. All of the other groups had significantly lower values.
