Influência do material oclusal na distribuição de tensões em próteses implantossuportadas unitárias

Objective: the aim of this study was to evaluate the influence of occlusal veneering material in single fixed implant-supported crowns through the 3-D finite element method. Material and methods: Four models were fabricated using the Rhinoceros 4.0, SolidWorks, and InVesalius softwares. Each model represented a block of mandibular bone with an external hexagon implant of 5 mm x 10 mm and different veneering materials including NiCr (1), porcelain (2), composite resin (3), and acrylic resin (4). An axial load of 200 N and an oblique load of 100 N were applied. Results: model (2) with porcelain veneering presented a lower stress concentration for the NiCr framework, followed by the composite resin and acrylic resin. The stress distribution to the implant and bone tissue was similar for all models. Conclusions: there is no difference of stress distribution to the implant and supporting structures by varying the veneering material of a single implant-supported prosthesis.

Influência da angulação do implante e tipo de intermediário na distribuição das tensões

The aim of this study was to evaluate the influence of implant angulation and abutment type (UCLA and Estheticone) on stress distribution in screw-retained implant-supported prostheses through photoelasticity. Three models were fabricated with photoelastic resin PL-2 (Vishay, Micro-Measurements Group, Inc Raleigh, N.C., USA) containing one external hexagon implant with 3.75x10mm (Master screw, Conexão Sistemas de Prótese Ltda., Arujá, São Paulo) with 0°, 17° and 30° degrees and a screw-retained prostheses with UCLA and Estheticone abutments. The assembly was positioned in a circular polariscope; axial and oblique (45° degrees) loads of 100N were applied in fixed points on the occlusal crown surfaces by a universal testing machine. The stress generated was photographed and analyzed qualitatively with appropriate software (Adobe Photoshop®). The results demonstrated the same number of fringes for both abutment types for each angulation, with fringes increasing in the same way. A higher number of fringes were closer in the oblique loading mode. It was concluded that there was no significant difference in stress distribution in prostheses with UCLA and Estheticone abutments. Higher stress concentrations were observed with increased implant angulation. Stress concentration and intensity were higher in the oblique load than in axial load application.

A continuidade contemporânea do pensamento de Georg Simmel: a compreensão da dinâmica conflitiva e dos fluxos nos processos de individualização na primeira modernidade e suas consequências sócio-culturais na modernidade reflexiva de Ulrich Beck

This thesis attempts to comprehend, through the work of Georg Simmel and Ulrich Beck, two distinct phases of modernity through the concept of individualism and individualization processes arising therefrom. A substantial formulation of the concept that remits to the conceptual transposition unscathed from one reality to another is not the main focus of this study. This is about, in advance, two distinct realities, conceptual and comparative examination that aims to weave the points pertaining to echoes - internalized and modified according to the complexity of the historical premises - the thought of Simmel in theoretical perspective of Beck. The forms can be characterized as individualism according to the socio-philosophical mores of Simmel in the intention to understand the forms assumed by individualism in modern history, as well as the derived individualization processes sustained by individual law. Therewith, is intended to transpose the optical analysis of contemporary Ulrich Beck and reap, through conceptual analysis, the points that refer to the influence and continuity of thought of Georg Simmel
