1. Toughening of bio-PE upon addition of PCL and PEgAA
Abstract Researches of polymer blends based on biological and biodegradable polymers appear as a viable alternative to develop environmentally friendly materials. Therefore, the aim of this research was to produce compounds made with biological polyethylene, i.e., Biopolyethylene, Bio-PE, added to the biodegradable Polycaprolactone (PCL) and functionalized b

2. Avaliação da customização por desgaste de pinos pré-fabricados de fibra de vidro / Evaluation of fibre posts submitted to customization of the apical portion
The purpose of this study was to evaluate fibre posts (White Post DC/FGM) submitted to customization of the apical portion. Experiment 1: 5 #4 posts were divided into five groups (G) and submitted to different custom adaptation treatments: GA no surface treatment, GB- industrial shaping tool (Dentsply), GC- #3195 fine diamond bur (KG Sorensen), GD- medium-gr

3. Post surface conditioning: effect on bond strength to composites after aging and on flexural strength of fiber posts. / CONDICIONAMENTO DA SUPERFÍCIE DE PINOS DE FIBRA DE VIDRO: INFLUÊNCIA NA RESISTÊNCIA ADESIVA APÓS CICLAGEM MECÂNICA E NA RESISTÊNCIA À FLEXÃO DOS PINOS
Aim: To evaluate the bond strength between glass fiber post and intrarradicular dentin or core composite resin after several post surface treatments, and the effect of surface treatments on posts flexural strength. Material and methods: The following post surface treatments were evaluated: G1- no conditioning; G2- cleaning with alcohol (AL); G3- AL + silane

4. RESISTÊNCIA À FRATURA DE DENTES COM DIFERENTES GRAUS DE FRAGILIZAÇÃO RADICULAR RECONSTRUÍDOS COM OU SEM PINOS ACESSÓRIOS / FRACTURE STRENGTH OF WEAKENED TEETH RESTORED WITH OR WITHOUT ACCESSORY POSTS.
At this work, fracture strength of bovine teeth with different weakened root levels and rebuilded with glass fiber posts used in a unique way or associated with accessory glass fiber posts was evaluated. Fifty bovine mandibular incisors with similar mesio-distal and bucco-lingual dimensions were used at the study. They were sectioned at 14 mm from the apex a

5. Biomechanical analysis of the stresses generated by different disocclusion patterns in an implant-supported mandibular complete denture
OBJECTIVES: This study evaluated by three-dimensional finite element analysis the tensions generated by different disocclusion patterns (canine guide and bilateral balanced occlusion) in an implant-supported mandibular complete denture. MATERIAL AND METHODS: A three-dimensional model of implant-supported mandibular complete denture was fabricated according t

6. Resistencia ao impacto da união dente-resina acrilica sob efeito da desinfecção simulada por energia de microondas / Effect of simulated microwave disinfection on bond strength of acry teeth and denture base resins
The aim of this study was to evaluate the effect of microwave disinfection in bond strength of acrylic teeth and a denture base resin. A hundred sixty rectangular wax patterns (30x15x5mm) were embedded in flasks with type III dental stone. After cristalization, the resulting moulds were filled with laboratorial silicone (Zetalabor), in which a molar acrylic

7. Distribuição das tensões geradas em implantes interconectados com barra dolder, após solda a laser
The Implant-retained prostheses need passivity and justness in their settlement, which are considered prerequisites for the osseointegration success. To minimize distortions and to promote passive settlement it is used the cut and solder of the piece. This work investigated, through photoelasticity, the distribution of stress generated by implants interconne

8. In vitro study of the fit of cast post and core, obtained from different acrylic resin patterns / Estudo in vitro da adaptação de retentores intra-radiculares fundidos, modelados com diferentes resinas acrílicas autopolimerizáveis
Endodontically treated teeth are often mutilated by caries and access requirements. The remaining structure requires special treatment to prevent further destruction. When a large portion of the clinical crown has been lost, it is often impossible to achieve sufficient anchorage of a restoration in the remaining dentin. In such situations, a root-canal-retai

9. Avaliação do desajuste marginal de coroas totais fundidas em titanio comercialmente puro utilizando diferentes padrões para fundição / Evaluation of marginal misfit of casting commercially pure titanium total crow using differrent pattern for casting
Patterns for casting metallic restorations are usually obtained from wax. However, it is speculated that increased marginal misfits could be created caused by dimensional changes during the removal of the pattern from the cast. Therefore, chemically activated acrylic resin is a routinely option in dental commercial laboratories. The characteristics of titani

10. Influence of the recast and different marginal configurations in the cervical and interior adaptation of Ni-Cr alloy total metallic crowns / Influencia da refusão de uma liga de niquel-cromo na adaptação cervical e interna de coroas totais com diferentes configurações marginais
The aim of the present study was to verify the influence of the heat source on the castability and hardness of a Ni-Cr-based commercial alloy ? VERA BONO II - in three different conditions: new (first use), recast, and new mixed with scraps. In order to evaluate castability, 10 specimens were made for each alloy condition, using a polyester sieve with 11x11

11. Biomechanics load transmission single implants according to prosthetic materials photoelastic and dinamic analysis / "Biomecânica da transmissão de cargas a implantes unitários em função dos materiais protéticos: análise fotoelástica e dinâmica"
Less rigid oclusal materials such as acrylic resins are often used in prosthesis over implants because they are supposed to diminish the loads transferred to the bone; however there is no scientific evidence to support this theory. The objective of this work was to compare by photoelastic and dynamic analysis the load transfer after oclusal loads over single

12. Avaliação da resistência à fratura de dentes tratados endodonticamente restaurados com pinos dentários e com pinos de fibras de polietileno / Evaluation of Fracture Resistance of Endodontically Treated Teeth Reconstructed with Dentinal Post and Cores and Polyethylene Woven Fiber Ribbon Post and Cores
Fracture resistance of endodontically treated teeth reconstructed with polyethylene woven fiber ribbon post and cores and dentinal post and cores has been evaluated. For that purpose, 60 human maxillary canines were selected, cut on the cementoenamel junction, endodontically treated (non- filled canal to a depth of 8mm)and fixed in acrylic resin blocks. The
