“…Other studies showed greater 3‐point flexural strength values for the nanoceramic resin when compared with PICN. Argyrou et al showed no statistical difference between the mean values of the nanoceramic resin (170 MPa) and a leucite reinforced glass–ceramic (159 MPa), both presenting greater values compared with PICN (124 MPa) and feldspathic ceramic (120 MPa). Choi et al also found greater values of 3‐point flexural strength for the nanoceramic resin (159.1 MPa) when compared with PICN (140.1 MPa).…”

“…Considering edge chipping resistance, Argyrou et al compared PICN material with other restorative materials (nanoceramic resin, feldspathic porcelain and leucite reinforced glass–ceramic). All restorative materials were cemented to a composite resin substrate and the edge chippings were produced using a diamond indenter.…”

“…Ao avaliar o desempenho quanto à resistência e rigidez à flexão, será possível um melhor conhecimento de aspectos da fratura deste tipo de material, do módulo de elasticidade, da repetibilidade da tensão de ruptura dos mesmos (quantificada pelo módulo de Weibull, Argyrou, (2015). Assim como uma avaliação da economia obtida no custo final da matéria prima, que poderá justificar, ou não, o aumento de custo relativo ao retorno das peças já utilizadas pelo consumidor, bem como o reaproveitamento de peças defeituosas geradas dentro do processo produtivo normal.…”

AGRADECIMENTOSPrimeiramente a Deus que esteve sempre presente, me fazendo cada vez mais convicto da importância de nossa fé para alcançarmos os nossos objetivos. No presente trabalho aborda-se, através de análise estatística de Weibull como ferramenta de avaliação, a resistência mecânica à flexão e módulo de elasticidade de pedra sintética com matéria prima proveniente de processo de reaproveitamento como carga de origem natural (rejeitos de marmorarias), e sintética (rejeitos de pedra sintética), comparando-os com o mármore sintético produzido a partir de matéria prima virgem (extraída de jazidas naturais). O trabalho objetiva desenvolver novas formulações da pedra sintética, utilizando matéria prima reciclada, com a devida comprovação técnica de viabilidade do processo, prospectando uma solução trivial para a problemática de resíduos sólidos better than the limestone, typically used, both as pure mineral, as product in subsequent recycling, up to the forth cycle (the density of this Group reduced 41%, minimum absolut value considering the synthetic stones). However, in relation to the Elastic Modulus E, both, the Synthetic Marble and the stone waste, presented a reduction from about 13.0GPa to 1.7 GPa on average, reducing its rigidity. Using analysis tools to evaluate mechanical properties, the work also includes the feasibility of Articulated Support as an alternative testing tool to perform three points bending tests in irregular samples testing tool bending three points alternative to irregular samples, having proven its effectiveness for the final purpose the end designed, with better repeatability in testing, and better results than the conventional fixed support.

Fracture load of CAD/CAM-fabricated and 3D-printed composite crowns as a function of material thickness

et al. 2018

OBJECTIVES: Indirect CAD/CAM restorations can be fabricated using both subtractive and additive CAD/CAM technology. This study investigated the fracture load of crowns fabricated from three particle-filled composite CAD/CAM materials and one 3D-printed composite material. MATERIALS AND METHODS: Lava Ultimate, Cerasmart and Brilliant Crios were used as particle-filled composite CAD/CAM material and els-3D Harz as 3D-printed composite material. For each group, crowns with three different material thicknesses (0.5/1.0/1.5 mm) were fabricated. Control group was composed of ceramic-based CAD/CAM materials e.max CAD and Enamic. Totally, n = 180 crowns were fabricated and adhesively seated on SLA fabricated dies. Thermomechanical loading and fracture testing were performed. The data for fracture loading force were statistically analyzed by two-way ANOVA followed with multiple comparisons by post hoc Tukey's test (= 0.05). RESULTS: In contrast to ceramics, all particle-filled composite crowns with 0.5-mm thickness survived fatigue testing. Forces varied statistically significantly. Brilliant Crios showed highest maximum loading force with 1580.4 ± 521.0 N (1.5 mm). Two-way ANOVA indicated that both the material and the thickness affected the fracture load (p < 0.05). CONCLUSIONS: Particle-filled composite resin CAD/CAM materials may have advantageous material characteristics compared to ceramic CAD/CAM materials for minimal restoration thicknesses. CLINICAL RELEVANCE: Composite-based CAD/CAM materials may offer new possibilities in minimally invasive restorative treatment concepts.
