Comparison of different designs of implant-retained overdentures and fixed full-arch implant-supported prosthesis on stress distribution in edentulous mandible - A computed tomography-based three-dimensional finite element analysis

A finite element analysis was used to compare the effect of different designs of implant-retained overdentures and fixed full-arch implant-supported prosthesis on stress distribution in edentulous mandible. Four models of an human mandible were constructed. In the OR (O'ring) group, the mandible was restored with an overdenture retained by four unsplinted implants with O'ring attachment; in the BC (bar-clip) -C and BC groups, the mandibles were restored with overdentures retained by four splinted implants with bar-clip anchor associated or not with two distally placed cantilevers, respectively; in the FD (fixed denture) group, the mandible was restored with a fixed full-arch four-implant-supported prosthesis. Models were supported by the masticatory muscles and temporomandibular joints. A 100-N oblique load was applied on the left first molar. Von Mises (σvM), maximum (σmax) and minimum (σmin) principal stresses (in MPa) analyses were obtained. BC-C group exhibited the highest stress values (σvM=398.8, σmax=580.5 and σmin=-455.2) while FD group showed the lowest one (σvM=128.9, σmax=185.9 and σmin=-172.1). Within overdenture groups, the use of unsplinted implants reduced the stress level in the implant/prosthetic components (59.4% for σvM, 66.2% for σmax and 57.7% for σmin versus BC-C group) and supporting tissues (maximum stress reduction of 72% and 79.5% for σmax, and 15.7% and 85.7% for σmin on the cortical and trabecular bones, respectively). Cortical bone exhibited greater stress concentration than the trabecular bone for all groups. The use of fixed implant dentures and removable dentures retained by unsplinted implants to rehabilitate edentulous mandible reduced the stresses in the periimplant bone tissue, mucosa and implant/prosthetic components. © 2013 Elsevier Ltd.

Working paper on the eLAC 2018 Digital Agenda in consideration of Caribbean priorities for technology-supported development

eLAC 2018 will coordinate the implementation of programmes to support the use of information and communications technologies (ICTs) in achieving social and economic development goals for Latin America in the Caribbean during the 2015-2018 timeframe. The conceptual framework for this programme of work is described by the eLAC 2018 Digital Agenda, which is anticipated to be ratified by the fifth Ministerial Conference on the Information Society in Latin America and the Caribbean, to be held in August 2015 in Mexico City. There is a need for broader input from Caribbean countries to the eLAC 2018 Digital Agenda. Accordingly, this working paper reviews the document’s current draft, considering each of its objectives in the context of Caribbean development needs. Amendments are recommended to 12 of the objectives. Two additional objectives are also proposed, in the areas of regional coordination on universal service funds, and the establishment of a spatial data infrastructure to support the use of geographic information systems. Representatives of Caribbean countries are invited to use the contents of this document as an input to the development of their own proposed amendments for inclusion in the final version of the eLAC 2018 Digital Agenda.

Escola em tempo de inclusão: ensino comum, educação especial e ação do fonoaudiólogo

This article refl ects about the action of the school speech therapist presented in a panel discussion proposed by the Public Health Department entitled: “School time of inclusion: common teaching, special education and speech therapist’s action” during the 19th SBFa’s Congress at the WTC Sheraton in São Paulo. The refl ections triggered aimed to provide elements for the systematization of actions from different sectors guided by ethical principles, theory and practice that enable collaborative relationships between educators and speech therapists. The text mantained the order of presentations that have focused on: 1) the challenges of speech-language intervention in the processes of inclusion and exclusion of the school: from the promotion of oral and written language, to the approaches of the so-called language disorders; 2) the interface between Speech Therapy and Education; 3) the role of the speech therapist in the context of Inclusive and Special Education. The authors support the position that the work done at the interface Speech Therapy and Education has the potential to contribute to school’s inclusion processes that will be capable to subvert the discriminatory logic that imposes in daily school the binomium inclusion / exclusion. The theoretical and methodological approaches presented by the authors are supported in a humane and civic vision care, training and social participation.

Practising Arithmetic Using Educational Video Games with an Interpersonal Computer

Studies show the positive effects that video games can have on student performance and attitude towards learning. In the past few years, strategies have been generated to optimize the use of technological resources with the aim of facilitating widespread adoption of technology in the classroom. Given its low acquisition and maintenance costs, the interpersonal computer allows individual interaction and simultaneous learning with large groups of students. The purpose of this work was to compare arithmetical knowledge acquired by third-grade students through the use of game-based activities and non-game-based activities using an interpersonal computer, with knowledge acquired through the use of traditional paper-and-pencil activities, and to analyze their impact in various socio-cultural contexts. To do this, a quasi-experimental study was conducted with 271 students in three different countries (Brazil, Chile, and Costa Rica), in both rural and urban schools. A set of educational games for practising arithmetic was developed and tested in six schools within these three countries. Results show that there were no significant differences (ANCOVA) in the learning acquired from game-based vs. non-game-based activities. However, both showed a significant difference when compared with the traditional method. Additionally, both groups using the interpersonal computer showed higher levels of student interest than the traditional method group, and these technological methods were seen to be especially effective in increasing learning among weaker students.

An esthetics rehabilitation with computer-aided design/ computer-aided manufacturing technology

This paper describes a case of a rehabilitation involving Computer Aided Design/Computer Aided Manufacturing (CAD-CAM) system in implant supported and dental supported prostheses using zirconia as framework. The CAD-CAM technology has developed considerably over last few years, becoming a reality in dental practice. Among the widely used systems are the systems based on zirconia which demonstrate important physical and mechanical properties of high strength, adequate fracture toughness, biocompatibility and esthetics, and are indicated for unitary prosthetic restorations and posterior and anterior framework. All the modeling was performed by using CAD-CAM system and prostheses were cemented using resin cement best suited for each situation. The rehabilitation of the maxillary arch using zirconia framework demonstrated satisfactory esthetic and functional results after a 12-month control and revealed no biological and technical complications. This article shows the important of use technology CAD/CAM in the manufacture of dental prosthesis and implant-supported.

Two extensions for the ALWABP: Parallel stations and collaborative approach

In this article, we introduce two new variants of the Assembly Line Worker Assignment and Balancing Problem (ALWABP) that allow parallelization of and collaboration between heterogeneous workers. These new approaches suppose an additional level of complexity in the Line Design and Assignment process, but also higher flexibility; which may be particularly useful in practical situations where the aim is to progressively integrate slow or limited workers in conventional assembly lines. We present linear models and heuristic procedures for these two new problems. Computational results show the efficiency of the proposed approaches and the efficacy of the studied layouts in different situations. (C) 2012 Elsevier B.V. All rights reserved.
