Influence of substrate, cement and aging on the biaxial flexural strength of lithium disilicate
Objective: To evaluate the biaxial flexural strength (BFS) of lithium disilicate (L), cemented on different substrates (epoxy resin-E and metal-M) with dual-cure resin cement (Rc) and zinc phosphate cement (Zc), not aged, thermally aged (TC) or thermo-mechanical aged (TC/MC).

Influence of substrate, cement and aging on the biaxial flexural strength of lithium disilicateInfluência do substrato, cimento e envelhecimento na resistência a flexão biaxial do dissilicato de lítioAgingCementationCeramicsFlexural strengthLithium disilicateObjective: To evaluate the biaxial flexural strength (BFS) of lithium disilicate (L), cemented on different substrates (epoxy resin-E and metal-M) with dual-cure resin cement (Rc) and zinc phosphate cement (Zc), not aged, thermally aged (TC) or thermo-mechanical aged (TC/MC). Material and Methods: Disks of L, E, and M were fabricated, and the cementation was performed according to the following groups: ERc (L+E+Rc); MRc (L+M+Rc); MZc (L+M+Zc); EZc (L+E+Zc). Ten samples from each described group were tested in BFS, ten more samples were subjected to TC (1×104 cycles between 5 ºC and 55 ºC water), and the last 10 samples were subjected to TC/MC (MC: 1.2×106 cycles, 50 N, 3.8 Hz). The BFS test was performed and scanning electron microscopy (SEM) was performed to evaluate the failure mode. The effect of the cementation strategy (cement/substrate) was compared in each aging method and the effect of the aging method was evaluated for each cementation strategy by one-way ANOVA and Tukey post-hoc test (α=0.05). Results: The strength values were highest to M (237.8 ~ 463.9 MPa), in comparison to the E (41.03 ~ 66.76 MPa), despite aging and luting agent. Flexural strength data decreased after TC and TC/MC in groups cemented with Zc, but was stable when cemented with Rc. SEM analysis indicated that failure origins were located at the tensile surface of the L. Conclusion: Lithium disilicate discs cemented to the metallic substrate presented the highest biaxial flexural strength. The cementation with dual-cure resin cement did not decrease BFS after aging.Departamento de Odontologia Restauradora Faculdade de Odontologia Universidade de São Paulo, SPDepartamento de Odontologia Universidade Federal de Juiz de Fora, MGDepartamento de Odontologia Universidade Braz Cubas, SPDepartamento de Materiais e Dentários e Prótese Instituto de Ciência e Tecnologia Unesp, SPDepartamento de Odontologia Universidade de Taubaté, SPDepartamento de Materiais e Dentários e Prótese Instituto de Ciência e Tecnologia Unesp, SPUniversidade de São Paulo (USP)Universidade Federal de Juiz de ForaUniversidade Braz CubasUniversidade Estadual Paulista (UNESP)Universidade de Taubaté2025-04-29T20:08:48Z2023-10-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://dx.doi.org/10.4322/bds.2023.e3923Brazilian Dental Science, v. 26, n. 4, 2023.2178-6011https://hdl.handle.net/11449/30723710.4322/bds.2023.e39232-s2.0-85174919374Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengBrazilian Dental Scienceinfo:eu-repo/semantics/openAccessde LIMA, Leonardo CustódioMiranda, Jean Soaresde CARVALHO, Ronaldo Luis AlmeidaBarcellos, Aline Serrado de Pinho [UNESP]Amaral, MarinaKimpara, Estevão Tomomitsu [UNESP]2025-04-30T13:56:09Zoai:repositorio.unesp.br:11449/307237Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462025-04-30T13:56:09Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false |

Material and Methods: Disks of L, E, and M were fabricated, and the cementation was performed according to the following groups: ERc (L+E+Rc); MRc (L+M+Rc); MZc (L+M+Zc); EZc (L+E+Zc). Ten samples from each described group were tested in BFS, ten more samples were subjected to TC (1×104 cycles between 5 ºC and 55 ºC water), and the last 10 samples were subjected to TC/MC (MC: 1.2×106 cycles, 50 N, 3.8 Hz). The BFS test was performed and scanning electron microscopy (SEM) was performed to evaluate the failure mode. The effect of the cementation strategy (cement/substrate) was compared in each aging method and the effect of the aging method was evaluated for each cementation strategy by one-way ANOVA and Tukey post-hoc test (α=0.05). Results: The strength values were highest to M (237.8 ~ 463.9 MPa), in comparison to the E (41.03 ~ 66.76 MPa), despite aging and luting agent. Flexural strength data decreased after TC and TC/MC in groups cemented with Zc, but was stable when cemented with Rc. SEM analysis indicated that failure origins were located at the tensile surface of the L. Conclusion: Lithium disilicate discs cemented to the metallic substrate presented the highest biaxial flexural strength. The cementation with dual-cure resin cement did not decrease BFS after aging. |
