ABSTRACT
PURPOSE: The present study aimed to identify, through a critical review of the literature, the success factors associated with the splinting of fixed prostheses on adjacent implants of the posterior sectors in partially edentulous patients compared with those not splinted. STUDY SELECTION: A MEDLINE strategy was implemented based on a research question to systematically search and extract information from databases (PubMed and Scopus) using MeSH terms/keywords identified for each domain. Systematic reviews, clinical and in vitro studies were selected and classified according to eligibility criteria based on the research question and level of evidence using the PRISMA flowchart. RESULTS: A total of 32 studies were selected for data extraction and analysis according to study design (three systematic reviews, 14 clinical studies, and 15 in vitro studies). Overall, the studies found no significant difference in the association between the survival rate and prosthesis type. In clinical studies, there have been no differences in marginal bone loss between splinted and non-splinted prostheses, and the influence of peri-implant status and restorative materials has been poorly evaluated. The distribution of stress and loads determined in the in vitro studies showed results that could favor splinted prostheses; however, are generally associated with implant design. CONCLUSIONS: The need for splinted or non-splinted adjacent implant-supported prostheses remains controversial. The reviewed evidence indicates that factors such as implant size and its relationship with coronal height could be important in decision-making.

Objetivo: Estudio de la Mortalidad por Enfermedades Infecciosas Intestinales (CIE-10: A00-A09) (EII) en los menores de 1 año en Venezuela según tiempo, persona, etiología y lugar durante 1996-2008. Materiales y métodos utilizados: Las fuentes son los Anuarios de Mortalidad del Min. Salud y del Instituto Nacional de Estadística. Análisis en números absolutos y cálculos de tasas específicas de menores de 1 año según sexo, etiología, entidad federal y tiempo, promedios, razones y proporciones. Correlación de Pearson entre tasa de mortalidad infantil por EII con Índice de Desarrollo Humano (IDH) (p < 0,05). Análisis con Microsoft Excel 2010 y SPSS.13.00. Resultados: Las muertes disminuyeron mucho, las tasas del primer trienio pasan de 3,18 por mil a 0,66; cayeron casi 5 veces. El índice de masculinidad es 1,33; estable en el lapso. Las EII son diarreas y gastroenteritis de presunto origen infeccioso; bacterianas (94,3%): Salmonella, Shigella e intoxicaciones intestinales bacterianas (1,5%); amebiasis y protozoarios (3,8%); el resto virales (0,05%). Las tasas varían en extremo por entidades federales. El último trienio, Delta Amacuro alcanza una tasa de 6,45; 10 veces por arriba de la tasa nacional, seguido a distancia por Zulia 2,64; Amazonas 2,28 y Apure 2,03. Se encontró una correlación de Pearson moderada (-0,416; p=0,03) inversamente proporcional entre la tasa de mortalidad y el IDH. Conclusiones: La mortalidad infantil por EII está descendiendo mucho en cifras absolutas y relativas. Es necesario mejorar el diagnóstico etiológico. Los estados con mayor población rural e indígena tienen las tasas más elevadas; abordando sanitariamente estos, tendríamos un gran impacto en la carga de muertes.
Objective: Study of the Mortality for Infectious Intestinal Diseases (IID) in 1-year-old minors in Venezuela according to time, person, etiology and place during 1996-2008. Materials and Used Methods: The sources are the Yearbooks of Mortality of the Min. and the National Institute of Statistics.Analysis are presented in absolute and relative numbers and calculations of specific rates of 1-year-old minors accordingto sex, etiology, federal entity and time, averages, rates and proportions. Pearson Correlation between rate of infant mortality for IID with Index of Human Development (IDH) (p<0.05). Analysis with Microsoft Excel 2010 and SPSS.13.00. Results: The deaths diminished very much, the rates of the first triennium dropped from 3.18 for thousand to 0.66; rates fell almost 5 times. The index of masculinity is 1.33, timelystable. The IID (94.3%) are diarrheas and gastroenteritis of presumable infectious origin; bacterial: Salmonella, Shigella and intestinal bacterial poisonings (1.5%); amebiasis and protozoans (3.8%); the rest viral (0.05%). The rates change much among the states. The last triennium, Delta Amacuroreaches a rate of 6.45, 10 times over of the national rate, followed distantly by Zulia 2.64, Amazonas 2.28 and Apure 2.03. There was a moderate correlation (-0.416; p=0.03) inversely proportional between the rate of mortality and the IDH. Conclusions: The infant mortality for IID is descending very much in absolute and relative numbers. It is necessary to improve the etiological diagnosis. States with high proportion of rural and indigenous population have the highest rates; tackling sanitarily these states, would have a great impact inthe load of deaths.
