1. Morse taper performance: A finite element analysis study
OBJECTIVES: To evaluate and compare the magnitude and distribution of stresses generated on implants, abutments and first molar metal-ceramic crowns using finite element analysis. METHODS: Preliminary three-dimensional models were created using the computer-aided design software SolidWorks. Stress and strain values were observed for two distinct virtual mo

2. Misfit and fracture load of implant-supported monolithic crowns in zirconia-reinforced lithium silicate
Abstract Zirconia-reinforced lithium silicate (ZLS) is a ceramic that promises to have better mechanical properties than other materials with the same indications as well as improved adaptation and fracture strength. Objective In this study, marginal and internal misfit and fracture load with and without thermal-mechanical aging (TMA) of monolithic ZLS and

3. Avaliação estrutural e biológica de coroas sobre implante confeccionadas com pilares de zircônia em região estética. / Structural and biological crowns on implant abutments made from zirconia region in aesthetics.
This prospective in vivo study has as main objective to evaluate the structural and biological performance of single-tooth implant supported-zirconia restoration in aesthetic region. Sixteen subjects were selected for the placement of thirty-one implants in aesthetic region. For the sample group fifteen single-tooth implants were fabricated. Zirconia abutmen

4. Estudo clínico controlado randomizado boca-dividida de próteses implantossuportadas unitárias sobre pilares metálicos e de zircônia em região estética: resultados clínicos preliminares após 110 dias em função. / Clinical randomized controlled split-mouth implant-prosthesis unit on metal and zirconia abutments in aesthetic region: preliminary clinical results after 110 days function.
O objetivo deste estudo controlado, prospectivo, longitudinal, randomizado tipo boca-dividida foi avaliar os parâmetros clínicos peri-implantares de próteses unitárias implantossuportadas em região anterior e posterior confeccionadas sobre pilares de zircônia versus metálico. Foram selecionados 16 indivíduos para instalação de 35 implantes dentári

5. A 3-year follow-up study of all-ceramic single and multiple crowns performed in a private practice: a prospective case series
OBJECTIVES: Zirconia-based prostheses are commonly used for aesthetic crown and fixed restorations, although follow-up data are limited, especially for implant-supported crowns. The aim of this study was to evaluate the threeyear clinical results of the installation of 463 zirconia core crowns by a general dental private practice. METHODS: This study followe

6. Resistência de união da interface coping cerâmico pilar de implante variando o agente cimentante antes e após ciclagem térmica / Bond strength of the ceramic coping-implant abutment interface varying luting agent before and after thermal cycling
Objective: The aim of the present study was to evaluate the bond strength of the ceramic coping-abutment implant interface according to the luting agent, before and after thermal cycling. Methods: A total of forty sets of ceramic copings (IPS e.max) and solid pillar 5.5/ regular analogue were divided according to the luting agent (n=10): (OZ) zinc oxide with

7. Evaluation of abutment and perimplantar region deformation of implant-supported screwed prostheses: an study using strain gauges / Avaliação da deformação do intermediário e região perimplantar de próteses implanto-suportada unitárias parafusada: estudo através da extensometria
The dental implant depends on the supporting bone for its stability and functional longevity. Mechanical behavior and trabecular bone structure affect the interface with the implant. Such knowledge may provide a basis for improvements in the current implant function and design, decreasing bone crest resorption and failure at bone-implant junction. Adequate q

8. All-ceramic and porcelain-fused-to-metal fixed partial dentures: a comparative study by 2D finite element analyses
All-ceramic fixed partial dentures (FPDs) have an esthetic approach for oral rehabilitation. However, metal-ceramic FPDs are best indicated in the posterior area where the follow-up studies found a lower failure rate. This 2D finite element study compared the stress distribution on 3-unit all-ceramic and metal-ceramic FPDs and identified the areas of major r

9. Caracteristicas de superficies, adsorção de proteinas e aderencia bacteriana em diferentes materiais odontologicos / Surface characteristics, proteins adsorption and bacterial adherence on different dental materials
The use of osseointegrated implants for replacing missing teeth is an important alternative in current dentistry. One of the most important conditions, which relates to the future success of implant procedures, is provided by the surface properties of the implant and its prosthetic abutments. Since these components penetrate through the gingival mucosa and a
