To investigate the effect of adhesive type and long-term aging on shear bond strength (SBS) between silica-based ceramics composite cement (CC).
Glaze application on monolithic zirconia (Y-TZP) can be a practical approach to improve the mechanical properties of this material. Objective Our study evaluated effect glazing side and cycling biaxial flexure strength (BFS) Y-TZP. Methodology Eighty sintered Y-TZP discs (Ø:12 mm; thickness: 1.2 mm - ISO 6872) were produced randomly assigned into eight groups (n=10), according factors "glazing side" (control – no glazing; GT glaze tensile side; GC compression GTC both sides) "mechanical...
Abstract Purpose To evaluate the effect of different surface treatments and adhesive cementation on miniflexural strength (MFS) monolithic zirconia. Materials Methods Two‐hundred forty (240) sintered bars translucent zirconia (Z T ) ultra‐translucent UT were obtained (8 mm ×2 ×1 mm). The divided into 16 groups ( n = 15) according to factors “Zirconia” Z ), “Cementation” (Cem) “surface treatment” (Ctrl:Control, Al:Aluminum oxide/Al 2 O 3 50 µm, Si:Silica/SiO coated alumina particles oxide 30...

Para tanto, conta assistência médica e enfermagem ininterruptas, equipamentos específicos, recursos humanos especializados acesso a aparelhagem sofisticada, destinada diagnóstico terapêutica, manutenção da Este artigo apresenta uma reflexão em torno das possibilidades processos do morrer tratamento intensivo, base pesquisa etnográfica hospital público universitário cidade Rio Janeiro. Apesar contato...
Este artigo objetiva apresentar e refletir sobre o processo de transmissão conhecimentos habilidades técnicas para residentes cirurgia geral em um hospital público universitário na cidade do Rio Janeiro. A partir etnografia centro cirúrgico – setor que os aprendem, prática, como conduzir uma –, foi realizada pesquisa qualitativa, com observação participante totalizando 137 horas, entrevistas cirurgiões, professores cirurgia. As interações entre cirurgiões gerais, geral, anestesistas, equipe...
The aim of this study was to evaluate the effect type preheated resin composite on microtensile bond strength (µTBS) between dentin and feldspathic ceramic inlays. Thirty healthy human premolars received inlay preparations for restorations were then divided into three treatment groups according luting agent (n = 10): Conventional Resin Cement (RC), Preheated Nanofilled Methacrylate-Based (MB), Microhybrid Silorane-Based (SB). 55 °C, considering cementation group. After cementation, sets cut...
In the RLT (Rapid Layer Technology), veneering ceramic and framework are fabricated by computer-aided design/computer-aided manufacturing (CAD/CAM) then cemented to obtain restoration. This study aimed evaluate effect of thickness manufactured technique on fracture resistance (FR) bilayer crowns with zirconia frameworks. Twenty frameworks twenty feldspathic posterior two different occlusal thicknesses (1mm=TF1; 2mm=TF2) were using CAD/CAM system. The specimens luted an epoxy resin abutment...
This study aimed to evaluate the influence of cement type and mechanical cycling on push-out bond strength (σ) fiber posts luted root canals. Eighty bovine single-root teeth were prepared roots included with chemically cured acrylic resin. The specimens allocated into 8 groups (n = 10) considering factors 'cement' (glass ionomer – GIC, resin reinforced glass RRGIC, conventional dual-cure CRC, self-adhesive SARC) 'mechanical cycling' (non-aged aged mc). dentin treated according...
A reabilitação de pacientes parcialmente edêntulos com desgaste dentário severo e dimensão vertical oclusão reduzida é desafiadora complexa. Objetivo: Descrever o restabelecimento da parâmetros estéticos uma prótese parcial removível do tipo overlay (PPRO) auxílio um JIG estético modificado. Relato caso: Paciente sexo masculino, 58 anos idade, procurou serviço odontológico queixando-se insatisfação a estética sorriso perda dos dentes posteriores. Ao exame clínico, foram observados excessivo...
Abstract Objective: To evaluate the thermocycling effect of 3D-printed resins on flexural strength, surface roughness, microbiological adhesion, and porosity. Materials methods: Specifically, 150 bar specimens (8 × 2 mm) 100 blocks 8 were made divided among five groups, according to two factors: “material” (AR: acrylic resin, CR: composite BIS: bis-acryl CAD: CAD/CAM PMMA PRINT: resin) “aging” (non-aged aged – TC). Half samples from each group subjected (10,000 thermocycles; 5–55 °C), rest...
