Internal oblique line implants in severe mandibular atrophies

2020

Background Maxillary atrophy may be related to mechanical, inflammatory or systemic factors, being a consequence of a reduction in the amount and quality of available bone. Several surgical techniques have been developed for the restoration of bone volume needed for placing dental implants; guided bone regeneration or three-dimensional reconstructions with autologous bone, inter alia, are techniques described in the literature which demonstrate this, all of which preceded by a proper prosthetic surgical assessment. Even when the majority of authors recommend the use of these techniques prior to placing implants, it has been shown that implants with a smaller diameter and length may be place…

Maxillary first molar with three mesiobuccal canals confirmed with spiral computer tomography

2012

Anatomic variations in root canal morphology have become easier to detect with the rapid advancements in clinical and diagnostic aids. Also an increased awareness of unusual anatomic morphology and a better understanding of the root canal system guides the clinician in diagnosis and treatment of such variations in order to achieve a successful endodontic outcome. Mesiobuccal root of first maxillary molar teeth have been considered to be one of the most complex and challenging root canal systems. This case report presents a successful management of a third canal in the mesiobuccal root of permanent maxillary first molar using dental operating microscope along with a modified access preparati…

In-house versus external basic research and first-to-market innovations

2016

This paper explores to what extent conducting internal basic research, as opposed to external basic research (i.e. outsourcing and collaboration with universities) encourages firms to bring new products into the market ahead of competitors, and contributes to innovation performance. The analysis is based on a sample of Spanish manufacturing firms over the period 2006–2012. Our findings suggest that conducting in-house basic research affects firm's propensity to introduce product novelties. Furthermore, performing this activity continuously affects the probability of being product-pioneer in low and medium–low tech sectors. Collaboration with universities also helps in introducing new produc…

Safety Culture: The Prediction of Commitment to Safety in the Manufacturing Industry

1998

This paper reports one aspect of a large-scale study of safety culture in 13 companies operating in the manufacturing sector in the UK. The study is based on data collected from three different domains of measurement relevant to the description of safety culture: workplace assessments, a survey of employee attitudes to safety – including questionnaire and interview data – and company accident records. The data described in this paper concern the prediction of perceived commitment to safety from employees' attitudes to safety as reported in a self-administered questionnaire. Commitment to safety was used as a marker of the strength of the organization's safety culture. The data showed that e…

Caring for older people: an analysis of the small business sector

2012

This study aims to analyse the small business sector in Spain for institutional care. In the Autonomous Region of Valencia, this sector is represented by non‐profit institutions. Our results show that non‐profit centres easily fulfil the legal requirements, especially with regard to personnel. They are generally of high quality and receive a large amount of volunteer work and funds from donators. Small business centres show an accurate daily cost per user of up to €56.48, a substantially lower rate than those offered by large centres.

Using Induced Ordered Weighted Averaging (IOWA) Operators for Aggregation in Cross-Efficiency Evaluations

2014

This paper proposes an enhancement of the cross-efficiency evaluation through the aggregation of cross-efficiencies by using a particular type of induced ordered weighted averaging IOWA operator. The use of a weighted average of cross-efficiencies for the calculation of the cross-efficiency scores, instead of the usual arithmetic mean, allows us to introduce some flexibility into the analysis. In particular, the main purpose of the approach we present is to provide aggregation weights that reflect the decision maker DM preferences regarding the relative importance that should be attached to the cross-efficiencies provided by the different decision-making units. To do it, an ordering is to b…

Effect of preemptive analgesia with ibuprofen in the control of postoperative pain in dental implant surgeries: A randomized, triple-blind controlled…

2019

Background Preemptive analgesia has as its basic principle the administration of analgesics before the onset of painful stimuli, in order to reduce or prevent postoperative pain, but this question is little explored in implantology. Thus, this study was conducted in order to evaluate the clinical efficacy of ibuprofen in pain prevention after unit implant surgery. Material and Methods For this triple-blind, parallel, placebo-controlled and randomized clinical trial, 54 insertion surgeries of unitary implants were performed. Two groups have received two different protocols 1 hour before surgery: Ibuprofen group (IBU) 600 mg of ibuprofen; and (2) placebo group (maize starch). The intensity of…

Proactive Future Internet: Smart Semantic Middleware for Overlay Architecture

2009

Some initiatives towards Future Internet, e.g., GENI, DARPA's Active Networks, argue the need for programmability of the network components. Some other initiatives extend this with argumentation for declarative networking, where the behavior of a network component is specified using some high-level declarative language, with a software-based engine implementing the behavior based on that specification. Our Proactive Future Internet (PROFI) vision follows these initiatives targeting also the following two problems: interoperability of the network elements programmed by different organizations, and the need for flexible cooperation among network elements, including coordination, conflict reso…

EPA-0552 – Social rehabilitation and employment of people with intellectual disabilities

2014

Background Experience in the field of professional and social activation and employment of people with moderate and severe intellectual disabilities indicates the need to seek specific strategies for solving problems on the way into the labor market of people recruited from this social group. The analysis of the limitations and difficulties in recruiting these people, and based on samples taken before employing them on the open market, gave birth to the concept of developing an innovative system to support candidates for employment. Methods The development of the Project’Our work - preventing discrimination against disabled people in access to work, preceded by a very detailed analysis of t…
