A systematic review of the survival and complication rates of resin-bonded bridges after an observation period of at least 5 years

OBJECTIVES: The objectives of this systematic review were to assess the 5-year survival of resin-bonded bridges (RBBs) and to describe the incidence of technical and biological complications. METHODS: An electronic Medline search complemented by manual searching was conducted to identify prospective and retrospective cohort studies on RBBs with a mean follow-up time of at least 5 years. Patients had to have been examined clinically at the follow-up visit. Assessment of the identified studies and data extraction were performed independently by two reviewers. Failure and complication rates were analyzed using random-effects Poissons regression models to obtain summary estimates of 5-year proportions. RESULTS: The search provided 6110 titles and 214 abstracts. Full-text analysis was performed for 93 articles, resulting in 17 studies that met the inclusion criteria. Meta-analysis of these studies indicated an estimated survival of RBBs of 87.7% (95% confidence interval (CI): 81.6-91.9%) after 5 years. The most frequent complication was debonding (loss of retention), which occurred in 19.2% (95% CI: 13.8-26.3%) of RBBs over an observation period of 5 years. The annual debonding rate for RBBs placed on posterior teeth (5.03%) tended to be higher than that for anterior-placed RBBs (3.05%). This difference, however, did not reach statistical significance (P=0.157). Biological complications, like caries on abutments and RBBs lost due to periodontitis, occurred in 1.5% of abutments and 2.1% of RBBs, respectively. CONCLUSION: Despite the high survival rate of RBBs, technical complications like debonding are frequent. This in turn means that a substantial amount of extra chair time may be needed following the incorporation of RBBs. There is thus an urgent need for studies with a follow-up time of 10 years or more, to evaluate the long-term outcomes.

A systematic review of the success of sinus floor elevation and survival of implants inserted in combination with sinus floor elevation. Part II: transalveolar technique

OBJECTIVES: The objectives of this systematic review were to assess the survival rate of implants placed in sites with transalveolar sinus floor elevation. MATERIAL AND METHODS: An electronic search was conducted to identify prospective and retrospective cohort studies on transalveolar sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. Failure and complication rates were analyzed using random-effects Poisson regression models to obtain summary estimates/ year proportions. RESULTS: The search provided 849 titles. Full-text analysis was performed for 176 articles, resulting in 19 studies that met the inclusion criteria. Meta-analysis of these studies indicated an estimated annual failure rate of 2.48% (95% confidence interval (95% CI): 1.37-4.49%) translating to an estimated survival rate of 92.8% (95% CI): 87.4-96.0%) for implants placed in transalveolarly augmented sinuses, after 3 years in function. Furthermore, subject-based analysis revealed an estimated annual failure of 3.71% (95% CI: 1.21-11.38%), translating to 10.5% (95% CI: 3.6-28.9%) of the subjects experiencing implant loss over 3 years. CONCLUSION: Survival rates of implants placed in transalveolar sinus floor augmentation sites are comparable to those in non-augmented sites. This technique is predictable with a low incidence of complications during and post-operatively.

A systematic review of the success of sinus floor elevation and survival of implants inserted in combination with sinus floor elevation

OBJECTIVES: The objectives of this systematic review were to assess the survival rate of grafts and implants placed with sinus floor elevation. MATERIAL AND METHODS: An electronic search was conducted to identify studies on sinus floor elevation, with a mean follow-up time of at least 1 year after functional loading. RESULTS: The search provided 839 titles. Full-text analysis was performed for 175 articles resulting in 48 studies that met the inclusion criteria, reporting on 12,020 implants. Meta-analysis indicated an estimated annual failure rate of 3.48% [95% confidence interval (CI): 2.48%-4.88%] translating into a 3-year implant survival of 90.1% (95% CI: 86.4%-92.8%). However, when failure rates was analyzed on the subject level, the estimated annual failure was 6.04% (95% CI: 3.87%-9.43%) translating into 16.6% (95% CI: 10.9%-24.6%) of the subjects experiencing implant loss over 3 years. CONCLUSION: The insertion of dental implants in combination with maxillary sinus floor elevation is a predictable treatment method showing high implant survival rates and low incidences of surgical complications. The best results (98.3% implant survival after 3 years) were obtained using rough surface implants with membrane coverage of the lateral window.

Survival and failure rates of orthodontic temporary anchorage devices: a systematic review

AIM: The purpose of this study was to systematically review the literature on the survival rates of palatal implants, Onplants((R)), miniplates and mini screws. MATERIAL AND METHODS: An electronic MEDLINE search supplemented by manual searching was conducted to identify randomized clinical trials, prospective and retrospective cohort studies on palatal implants, Onplants((R)), miniplates and miniscrews with a mean follow-up time of at least 12 weeks and of at least 10 units per modality having been examined clinically at a follow-up visit. Assessment of studies and data abstraction was performed independently by two reviewers. Reported failures of used devices were analyzed using random-effects Poisson regression models to obtain summary estimates and 95% confidence intervals (CI) of failure and survival proportions. RESULTS: The search up to January 2009 provided 390 titles and 71 abstracts with full-text analysis of 34 articles, yielding 27 studies that met the inclusion criteria. In meta-analysis, the failure rate for Onplants((R)) was 17.2% (95% CI: 5.9-35.8%), 10.5% for palatal implants (95% CI: 6.1-18.1%), 16.4% for miniscrews (95% CI: 13.4-20.1%) and 7.3% for miniplates (95% CI: 5.4-9.9%). Miniplates and palatal implants, representing torque-resisting temporary anchorage devices (TADs), when grouped together, showed a 1.92-fold (95% CI: 1.06-2.78) lower clinical failure rate than miniscrews. CONCLUSION: Based on the available evidence in the literature, palatal implants and miniplates showed comparable survival rates of >or=90% over a period of at least 12 weeks, and yielded superior survival than miniscrews. Palatal implants and miniplates for temporary anchorage provide reliable absolute orthodontic anchorage. If the intended orthodontic treatment would require multiple miniscrew placement to provide adequate anchorage, the reliability of such systems is questionable. For patients who are undergoing extensive orthodontic treatment, force vectors may need to be varied or the roots of the teeth to be moved may need to slide past the anchors. In this context, palatal implants or miniplates should be the TADs of choice.

Mechanical and technical risks in implant therapy

PURPOSE: To systematically appraise the impact of mechanical/technical risk factors on implant-supported reconstructions. MATERIAL AND METHODS: A MEDLINE (PubMed) database search from 1966 to April 2008 was conducted. The search strategy was a combination of MeSH terms and the key words: design, dental implant(s), risk, prosthodontics, fixed prosthodontics, fixed partial denture(s), fixed dental prosthesis (FDP), fixed reconstruction(s), oral rehabilitation, bridge(s), removable partial denture(s), overdenture(s). Randomized controlled trials, controlled trials, and prospective and retrospective cohort studies with a mean follow-up of at least 4 years were included. The material evaluated in each study had to include cases with/without exposure to the risk factor. RESULTS: From 3,568 articles, 111 were selected for full text analysis. Of the 111 articles, 33 were included for data extraction after grouping the outcomes into 10 risk factors: type of retentive elements supporting overdentures, presence of cantilever extension(s), cemented versus screw-retained FDPs, angled/angulated abutments, bruxism, crown/implant ratio, length of the suprastructure, prosthetic materials, number of implants supporting an FDP, and history of mechanical/technical complications. CONCLUSIONS: The absence of a metal framework in overdentures, the presence of cantilever extension(s) > 15 mm and of bruxism, the length of the reconstruction, and a history of repeated complications were associated with increased mechanical/technical complications. The type of retention, the presence of angled abutments, the crown-implant ratio, and the number of implants supporting an FDP were not associated with increased mechanical/technical complications. None of the mechanical/technical risk factors had an impact on implant survival and success rates.

Hence each of the 30 contributions spans both a theoretical approach and concrete analysis of literary texts from different centuries and different Anglophone cultures.

El mundo lúdico en la literatura de Rabelais: la obra Gargantua y el repertorio de juegos del capítulo XXII de la edición 1542

En el presente estudio de tesis doctoral analizamos un texto literario francés del siglo XVI en el que aparecen 217 juegos. Como valor añadido se trata de parte de un texto reconocido mundialmente por la Literatura Universal como es el Gargantua de François Rabelais. A tenor de la conocida y famosa definición de Gimnasia establecida por Francisco de Amorós y Ondeano allá por 1830 en su Manuel d'éducation physique, gymnastique et morale, uno de los objetos de estudio en nuestra ciencia es la relación de nuestros movimientos con nuestras costumbres. Para ello indudablemente debemos recurrir a todo tipo de fuentes, escritas, orales o de otro tipo, para analizarlas. “La gimnasia es la ciencia razonada de nuestros movimientos, de sus relaciones con nuestros sentidos, nuestra inteligencia, nuestros sentimientos, nuestras costumbres y el desarrollo de todas nuestras facultades...” Costumbres, tradición e historia, en definitiva, que se contrasta con los medios utilizados en su análisis, herramientas TIC como son librerías digitales, buscadores de textos y palabras. A través del análisis de textos de diversa índole hemos ido obteniendo datos sobre los juegos. Estas fuentes han sido novelas, diccionarios, enciclopedias y ensayos desde el siglo XIV hasta obras contemporáneas. Se ha realizado un análisis estadístico de estas fuentes lo que ha dado a este estudio otro valor añadido desde un punto de vista metodológico. El resultado del estudio se ha plasmado en una colección de fichas creadas a partir de un estudio comparativo de diferentes fichas de juegos de autores de relevancia. ABSTRACT Gymnastics is the reasoned science of our movements, of its relations with our senses, our intelligence, our feelings, our customs and the development of all our faculties… In accordance with the all known famous definition of Gymnastics that established Don Francisco de Amorós and Ondeano in 1830 in his Manuel d'éducation physique, gymnastique et morale, one of the objects of study in our science is the relation of our movements with our customs. For it doubtlessly we must resort to all type of sources, written, oral or of another type, to analyze them. In the present doctoral thesis study we analyzed a French literary text of the XVI th century in which they appear 217 games. As added value treats world-wide from a recognized text by Universal Literature as it is the Gargantua of François Rabelais. Customs, tradition and history, really, that are resisted with means used in its analysis, TIC tools as they are digital libraries and tools to seek texts and words. Through text analysis of diverse nature we have been collecting data on the games. These sources have been novels, dictionaries, encyclopedias and tests from century XIV to contemporary works. A statistical analysis of these sources has been made which has given to this study another value added from a methodological point of view. The result of the study has been resumed in index cards created from a comparative cards study from different relevant authors.

Diseño de una herramienta para la aplicación de técnicas de minería de textos

El objetivo del presente trabajo es el estudio, diseño e implementación de una herramienta software, con interfaz gráfica de usuario, que permita aplicar diversas técnicas de análisis de textos de forma simple. Las técnicas de análisis, que serán implementadas en la herramienta, extraerán información de textos escritos en un lenguaje humano, es decir un lenguaje no artificial, y se le presentará al usuario. La herramienta permite la obtención de tres tipos de información: categorías a las que pertenece un texto, dentro de un conjunto de categorías predeterminadas; grupos de textos que son similares entre sí; y la polaridad de opinión expresada en un texto hacia el tema u objeto del que trata, que puede ser neutra, positiva o negativa.---ABSTRACT---The aim of this work is to study, design and implement a software tool, with graphical user interface, which will enable a user to easily apply various text analysis techniques. The techniques implemented in the tool will extract information from texts written in natural language, i.e. a non artificial language, and will present it to the user. The tool will extract three different types of information about a given set of texts: their categories (from a predefined set of categories), groups of similar texts, the polarity of the attitude expressed in the texts towards their topic.

BALAÃO – O QUE OUVE AS PALAVRAS DE EL, TEM O CONHECIMENTO DE ELYON E VÊ A VISÃO DE SHADDAI: UM ESTUDO DE NÚMEROS 22-24

A presente pesquisa busca avaliar exegeticamente o texto que se encontra na Bíblia, especificamente no livro de Números capítulos 22-24 que relata sobre um personagem conhecido como Balaão. A pesquisa tem também como objeto o estudo sobre o panteão de divindades relatado no mesmo texto, assim como também o estudo dos textos descobertos em Deir Alla, na Jordânia, que apresentam um personagem designado como Balaão, possivelmente o mesmo personagem de Nm 22-24. A motivação que levou ao desenvolvimento dessa pesquisa foi o fato de se ter deparado com os conceitos dos diversos nomes divinos exibidos no texto, além da questão do profetismo fora de Israel, assim como as possibilidades hermenêuticas que se abrem para a leitura desse texto bíblico. O conceito geral sempre foi o de que Israel era a única nação onde existiam “verdadeiros” profetas e uma adoração a um único Deus, o “monoteísmo”. O que despertou interesse foi perceber, especialmente por meio da leitura dos livros bíblicos, que o profetismo não se restringiu somente a Israel. Ele antecede à formação do antigo Israel e já existia no âmbito das terras do antigo Oriente Médio, e que Israel ainda demorou muito tempo para ser monoteísta. Quem é esse Balaão, filho de Beor? Estudaremos sobre sua pessoa e sua missão. Examinaremos os textos de Deir Alla sobre Balaão e sua natureza de personagem mediador entre o divino e o humano. Esse personagem é apresentado como um grande profeta e que era famoso como intérprete de presságios divinos. Analisaremos a importante questão sobre o panteão de deuses que são apresentados na narrativa de Balaão nomeados como: El, Elyon Elohim e Shaddai, além de Yahweh. Entendemos, a princípio, que o texto possui uma conexão com a sociedade na qual foi criado e usando da metodologia exegética, faremos uma análise da narrativa em questão, buscando compreender o sentido do texto, dentro de seu cenário histórico e social. Cenário este, que nos apresentou esse profeta, não israelita, que profere bênçãos dos deuses sobre Israel e que, além disso, pronuncia maldições sobre os inimigos desse mesmo Israel. Percebemos que, parte do texto pesquisado é apresentado sob a ótica de Israel sobre as outras nações. A pesquisa defende, portanto, que o texto de Nm 22-24, além de nos apresentar um profeta fora de Israel igual aos profetas da Bíblia, defende que, o panteão de divindades também era adorado por Israel e que tais nomes são epítetos de uma mesma divindade, no caso YHWH. Defende, também, um delineamento de um projeto de domínio político e militar de Israel sobre as nações circunvizinhas.

Computer speech synthesis: its status and prospects.

Computer speech synthesis has reached a high level of performance, with increasingly sophisticated models of linguistic structure, low error rates in text analysis, and high intelligibility in synthesis from phonemic input. Mass market applications are beginning to appear. However, the results are still not good enough for the ubiquitous application that such technology will eventually have. A number of alternative directions of current research aim at the ultimate goal of fully natural synthetic speech. One especially promising trend is the systematic optimization of large synthesis systems with respect to formal criteria of evaluation. Speech recognition has progressed rapidly in the past decade through such approaches, and it seems likely that their application in synthesis will produce similar improvements.

A Discursive Perspective on China's Global Politics of Climate Change, 1992-2013

This dissertation investigates China’s recent shift in its climate change policy with a refined discourse approach. Methodologically, by adopting a neo-Gramscian notion of hegemony, a generative definition of discourse and an ontological pluralist position, the study constructs a theoretical framework named “discursive hegemony” that identifies the “social forces” for enabling social change and focuses on the role of discursive mechanisms via which the forces operate and produce effects. The key empirical finding of this study was that it was a co-evolution of conditions that shaped the outcome as China’s climate policy shift. In examining the case, a before-after within-case comparison was designed to analyze the variations in the material, institutional, and ideational conditions, with methods including interviews, conventional narrative/text analysis and descriptive statistics. Specifically, changes in energy use, the structure of decision-making body, and the narratives about sustainable development reflected how the above three types of social force processed in China in the first few years of the 21st century, causing the economic development agenda to absorb the climate issue, and turning the policy frame for the latter from mainly a diplomatic matter to a potential opportunity for better-quality growth. With the discursive operation of the “Science-based development”, China’s energy policy has been a good example of the Chinese understanding of sustainability characterized by economic primacy, ecological viability and social green-engineering. This way of discursive evolution, however, is a double-edged sword that has pushed forward some fast, top-down mitigation measures on the one hand, but has also created and will likely continue creating social and ecological havoc on the other hand. The study makes two major contributions. First and on the empirical level, because China is an international actor that was not expected to cooperate on the climate issue according to major IR theories, this study would add one critical case to the studies on global (environmental) governance and the ideational approach in the IR discipline. Second and on the theory-building level, the model of discursive hegemony can be a causally deeper mode of explanation because it traces the process of co-evolution of social forces.

Black Koreans in Korean children’s literature : A study of Won You Soon’s book “Please find Chartlon Sunja Kim”

The purpose of this study is to depict and examine the perception of black Koreans in South Korean children’s literature. This study examines my research questions through four theoretical frameworks: “culture and identity”, “post-colonialism, nationalism and racism”, “blackness and black Koreans’ portrayal in Korean media” and “multiculturalism in Korea”. My study raises the question how multicultural literature can help or not promote a new perception of otherness in South Korea. The method used for this study is qualitative text analysis. The primary source of information is a close-reading of Won You Soon’s book “Please find Charlton Sunja Kim” and interviews with the author of this book. The findings show that there are still some stereotypes about black Koreans and blackness that prevail in South Korean society and can still be found in recent literary works.

Att marknadsföra med musik : en studie kring musik i reklamfilm och en artistprofils påverkan på ett varumärke

Due to the current digitalization of the music industry it has become more important than ever for musicians to get their music placed in advertising. This process is frequently described as a win-win situation for both sides: the musician gets money and exposure while the brand gets to ride on the musician’s pop-cultural position in society. The following thesis is focused on identifying the different ways brands work with music in their TV-advertising, and what effects the brand of the featured artist might have on the brand itself. Using text analysis, six advertisements all shown on Swedish TV during the first half of 2016 were analyzed, with the result that four major recurring themes were identified: nostalgia, text-related usage, making the advert memorable and making the advert into entertainment. The study also found three ways in which a band profile could serve a brand: (I) to make the advert an artifact of popular culture, (II) to let the brand ride on the bands success, (III) to give credibility to the brand. The study was based on brand theory, sensory branding and semiotics as well as David Hurons theory on the different usages of music in advertising.
