The effect of osseodensification on implant stability and bone density: A prospective observational study.

2019

Background The aims of this study were to evaluate the effect of implant site preparation in low-density bone using osseodensification method in terms of implant stability changes during the osseous healing period and peri-implant bone density using CBCT. Material and Methods This prospective observational clinical study included 24 patients who received 46 dental implants that were installed in low-density bone using the osseodensification method. CBCT was used to measure the bone density pre- and postoperatively and implant stability was measured using Periotest® immediately after implant insertion and then after 6 weeks and 12 weeks postoperatively. The data were analyzed using paired t-…

Measurement of dental implant stability by resonance frequency analysis : a review of the literature

2008

Dental implant treatment is an excellent option for prosthetic restoration that is associated with high success rates. Implant stability is essential for a good outcome. The clinical assessment of osseointegration is based on mechanical stability rather than histological criteria, considering primary stability (absence of mobility in bone bed after implant insertion) and secondary stability (bone formation and remodelling at implant-bone interface). The aim of this study was to review the literature on Resonance Frequency Analysis (RFA) as a method for measuring dental implant stability. An online search of various databases was conducted on experimental and clinical research published betw…

Estudio de la eficacia escolar en centros educativos de primaria mediante el uso de Modelos Jerárquicos Lineales

2021

espanolINTRODUCCION. Se presenta un estudio censal sobre la eficacia escolar en los centros educativos de primaria de la comunidad autonoma de La Rioja, un analisis secundario de una evaluacion diagnostica (ED) previa en esa comunidad. Se valoro el impacto de variables contextuales en los rendimientos de las asignaturas evaluadas no usando las puntuaciones medias brutas obtenidas en la ED, sino las puntuaciones medias ajustadas una vez controlado el efecto de variables contextuales. METODO. El control se realizo por modelizacion estadistica multinivel con modelos jerarquicos lineales en dos niveles: estudiantes y centros. Los residuos de los modelos se usaron como criterio de eficacia escol…

Elder Abuse in Live-in Migrant Carer Arrangements

2021

This chapter focuses on an issue rarely addressed in research: abuse and protection against abuse in live-in migrant carer (LIMC) arrangements. Based on a secondary analysis of data collected in LIMC arrangements in Germany, potential risks of abuse and protective factors against abuse are identified. The chapter shows that questions about abuse and protection against abuse in these arrangements have to be analyzed in the context of complex, interrelated factors, structures and processes. There is no clear answer as to whether LIMC arrangements increase or decrease the risk of abuse and neglect of older dependent people. Aside from the existing taboo against abuse in home-based care in old …

Bank Erosion and Secondary Circulation in a Meandering Laboratory Flume

2014

Abstract This paper reports peculiar results of experimental investigation on the secondary circulation motion of flow along a meander wave. Experiments were conducted in a large amplitude meandering laboratory channel for two values of the width-to-depth ratio. Here attention is focalized on how secondary motion affects the bank shear stress distribution, influencing the stability of the outer bank. The analysis essentially highlights that, especially for small width-to-depth ratio, as the channel curvature increases, besides the classical central-region secondary circulation cell a counter-rotating circulation cell forms in the outer-bank region. Such counter-rotating circulation cell all…

Role of Cytoreductive surgery in recurrent ovarian cancer

2010

Ovarian cancer is the leading cause of death from gynecologic malignancy in western countries, primarily because over 60% of patients with ovarian cancer will experience disease recurrence. Primary cytoreductive surgery and combination chemotherapy are the cornerstones of the initial treatment for epithelial ovarian cancer. The management of recurrent ovarian cancer is less clear than that of primary disease. The management of recurrent ovarian cancer is largely based on systemic chemotherapy, with surgery being offered only in selected individuals. Despite this, the benefits of surgery has been shown in a meta-analysis by Bristow et al. where the survival is influenced by the completeness …

Laparoscopic surgical management of localized recurrent ovarian cancer: a single-institution experience

2014

Background: Optimally, secondary cytoreduction is acknowledged as a valid option in terms of oncologic outcome for patients with platinum-sensitive recurrent ovarian cancer. In cases of localized relapse, a laparoscopic approach has been attempted at various institutions, but studies on its role for this subset of patients still are limited. This report describes the authors' experience using laparoscopic secondary cytoreduction for patients with localized recurrent ovarian cancer. The results from a retrospective analysis of a prospective case series are reported. Methods: Between October 2011 and May 2013, 29 patients with localized recurrent ovarian cancer were selected for a laparoscopi…

Diversity in Coherence : Strengths and Opportunities of Three Programs

2017

Author's accepted version (post-print). Although teacher educators may perceive their program and courses to be coherent, the question remains to what extent student teachers also are able to perceive the linkages within their programs. Coherence within teacher education programs is important for teacher candidates to build understanding of teaching. Our study draws upon survey data from 269 teacher candidates, in three different teacher education programs, located in three different countries (Norway, Finland, United States [California]) and compares these candidates’ perceptions of the coherence of their teacher education programs. Candidates from a program that has explicitly been workin…

Influence on self-efficacy of the degree of authenticity of the inquiry carried out in two secondary school science projects

2021

Las creencias sobre la propia capacidad para llevar a cabo con exito una tarea concreta (autoeficacia) influyen en la implicacion y la motivacion hacia dicha tarea. En las ultimas decadas se ha incrementado el foco de atencion hacia estas creencias en el area de ciencias no solo como uno de los predictores mas consistentes del desempeno real del alumnado, sino por la existencia de desigualdades sistematicas en la autoeficacia de chicos y chicas. Aunque el Aprendizaje Basado en Proyectos (ABP) en el aula de ciencias posee diversas caracteristicas que potencialmente pueden contribuir a la mejoria de la autoeficacia en ciencias del alumnado, las evidencias entre la relacion de los elementos de…
