Resistencia flexural y estabilidad de color en resinas híbridas y cerómeros empleadas en restauraciones indirectas
Flexural strength and color stability in hybrid resins and ceromers used in indirect restorations

Rev. Eugenio Espejo; 14 (1), 2020
Las restauraciones dentales con técnica indirecta fueron concebidas con el propósito de optimizar las propiedades mecánicas, físicas y químicas de los materiales polimerizados. En tal sentido, se realizó una investigación cuyo objetivo fue comparar restauraciones mediante la técnica indirecta uti...

Internal and marginal fit and fracture strength of narrow diameter dental implant-abutment assembly

Braz. dent. j; 31 (2), 2020
Abstract The aim of this study was to assess the internal and vertical marginal fit of metallic copings to abutments and the fracture strength of different narrow diameter dental implant/abutments, either submitted to thermomechanical cycling or not. Sixty-four implant/abutments (n=16) were divided into ...

Flexural strength of polyether ether ketone high-performance polyether in comparison with base metal alloy and zirconia ceramic

J. oral res. (Impresa); 9 (1), 2020
Optimal flexural strength is a critical prerequisite for prosthetic frameworks. This study aimed to assess the flexural strength of polyether ether ketone (PEEK) polymer compared to a base metal alloy and high-strength Zirconia ceramic commonly used in prosthodontic treatments. Materials and Methods: In ...

Effects of denture cleansers on denture material properties —an observational case—control study

J. oral res. (Impresa); 9 (1), 2020
Everyday use of denture cleansers to prevent microbial colonization on dentures can affect the properties of the denture base material. Limited literature is available on the effects of denture cleanser on reinforced resins. This study aimed to evaluate and compare the effect of denture cleanser on the f...

Efeito da largura temporal de pulso do Laser de Er: YAG nas características de superfície, adesão e propriedades mecânicas da zircônia

Este estudo avaliou os efeitos da variação da largura temporal de pulso do laser de Er:YAG nas características de superfície (morfologia, transformação de fase, rugosidade e perda de superfície), na resistência de união de um cimento resinoso (Panavia F 2.0, Kuraray, Okayama, Japão) e nas propr...

O uso de pino de fibra em dentes tratados endodonticamente

Este estudo envolve um estudo in sílico, um ensaio clínico randomizado e duas revisões sistemáticas com o objetivo de compreender a influência dos pinos de fibra (PF) na resistência à fratura de dentes tratados endodonticamente e restaurados e também, avaliar o efeito de tratamentos químicos den...

Mechanical properties and surface roughness of polymer-based materials containing DCPD particles

Abstract The purpose of this study was to synthesize dicalcium phosphate dihydrate (DCPD) particles functionalized with triethylene glycol dimethacrylate (TEGDMA) through different routes by varying the receptor solution: ammonium phosphate (AP groups) or calcium nitrate (CN groups) and the moment in whi...

The effect of ionizing radiation on properties of fluoride-releasing restorative materials

Abstract The purpose of this study was to evaluate the effect of ionizing radiation from high energy X-ray on fluoride release, surface roughness, flexural strength, and surface chemical composition of the materials. The study groups comprised five different restorative materials: Beautifil II, GCP Glass...
