L'entrée des jeunes dans la vie active en Bourgogne debut 2008

2009

Pour connaitre le devenir des jeunes, le ministère de l'Éducation nationale réalise chaque année une enquête avec l'appui des établissements scolaires et des centres de formation publics et privés. Cette note présente les résultats de la dernière interrogation menée en février 2008, et donne un aperçu de la diversité des premiers pas des anciens élèves et apprentis sur le marché du travail. En Bourgogne, 12500 jeunes agés de 21 ans en moyenne, ont été interrogés sur leur situation professionnelle à la sortie des formations professionnelles ou technologiques, de lycée ou de centre de formation d'apprentis.

Des compétences artistiques aux compétences professionnelles

2010

Les écoles supérieures d'art certifient des qualifications complexes et aux devenirs imprédictibles. Les études sur l'insertion professionnelle des diplômés des écoles d'art (DNSEP) menées jusqu'ici se sont attachées à décrire la qualité de leur insertion. Dans cette recherche, la réflexion porte sur la valorisation des compétences acquises en formation dans le contexte d'exercice professionnel. Les diplômés des promotion 2003 et 2005 occupant un emploi artistique au moment de l'enquête sont ainsi réinterrogés 4 à 6 ans après leur sortie de formation.

Relation between bone density and primary implant stability

2010

Aims: This study aims to relate bone density in Hounsfield units (Hu) with the primary implant stability measured by insertion torque (Ncm) and resonance frequency analysis (ISQ). Materials and Methods: Ten patients were included in this study. A total of 54 implant sites were provided from 10 computerized tomography scans. The computerized tomography scan was used for the preoperative evaluation of bone density for each patient. The bone mean density around planned implants was determined with Physioplanet TM software. Bone quality according resistance to drilling, insertion torque and resonance frequency measurements were recorded. Results: A statistically significant relationship was obs…

Design characteristics, primary stability and risk of fracture of orthodontic mini-implants: Pilot scan electron microscope and mechanical studies

2013

Objectives: Orthodontic mini-implants (OMIs) are increasingly used in orthodontics but can fail for various reasons. This study investigates the effects of OMI design characteristics on the mechanical properties in artificial bone. Material and Methods: Twelve self-drilling OMIs (2 small, 6 medium, 4 large) from 8 manufacturers were tested for their primary stability in simulated medium-high cancellous bone and the risk to fracture in high-density methacrylate blocks. For the assessments of the maximum insertion torque (IT) and torsional fracture (TF) 5 of each OMI were used and for the pull-out strength (POS) 10. The OMIs were inserted with a torque screwdriver (12 sec/360°) until the bott…

Implant insertion torque value in immediate loading : a retrospective study

2019

Background The aim of this study is to verify if the Insertion Torque Value (ITV) of 32 Ncm for immediate loading protocol (ILP), as indicated by literature, is still, with the advance in implant research, a real significant cut-off for long-term implant survival. Material and Methods In this retrospective study, data from 224 patients that during three years of clinical practice, were submitted to the insertion of 322 implants with immediate loading protocol, have been recorded, pooled and analyzed. Data were organized based on Insertion Torque Value (ITV): > 32 Ncm (CG) and 32 Ncm are still characterized by a lower crestal bone resorption, there are no statistically significant difference…

Influence of cortical bone and implant design in the primary stability of dental implants measured by two different devices of resonance frequency an…

2020

Background This study aimed to evaluate the effect of the implant design and the presence of cortical bone in the primary stability, as well as analyze the differences between the stability measurements obtained by two different resonance frequency analysis (RFA) devices. Material and methods A total of 80 Klockner implants of two different models [40 Essential Cone implants (group A) and 40 Vega implants (group B)] were used. The implants were placed in two polyurethane blocks that simulated the mechanical properties of the maxillary bone. One block featured a layer of cortical bone that was absent from the other block. The primary stability of all implants was measured by insertion torque…

Primary Stability of a Hybrid Self-Tapping Implant Compared to a Cylindrical Non-Self-Tapping Implant with Respect to Drilling Protocols in an Ex Viv…

2011

Background: Modifications of implant design have been intending to improve primary stability. However, little is known about investigation of a hybrid self-tapping implant on primary stability. Purposes: The aims of this study were to evaluate the primary stability of two hybrid self-tapping implants compared to one cylindrical non-self-tapping implant, and to elucidate the relevance of drilling protocols on primary stability in an ex vivo model. Materials and Methods: Two types of hybrid self-tapping implants (Straumann® Bone Level implant [BL], Straumann® Tapered Effect implant [TE]) and one type of cylindrical non-self-tapping implant (Straumann® Standard Plus implant [SP]) were investig…

Influence of Implant Connection, Abutment Design and Screw Insertion Torque on Implant-Abutment Misfit

2020

Background: An accurate fit at the implant-abutment interface is an important factor to avoid biological and mechanical complications. The aim of this study was to evaluate the marginal misfit at the implant-abutment interface on external and Morse taper connection, with straight and angulated abutments under different insertion torque loads. Materials and Methods: A total of 120 implants were used, 60 with external connection (EC) and 60 with Morse taper connection (IC). Straight (SA) (n = 60) and angulated abutments (AA) (n = 60) were randomly screwed to each connection at different torque levels (n = 10 each): 10, 20 and 30 Ncm. All specimens were subjected to thermal and cyclic loading …

Mobilités internationales des diplômés de l'enseignement supérieur français en phase d'insertion professionnelle : effets sur leurs débuts de carrièr…

2008

International mobility by French higher education graduates on entering the labour market: is it worth it once they return home?The construction of European graduate labour market, through increased international graduate mobility, cannot take place without it appearing beneficial forgraduates. Indeed, all types of mobility have a cost, even if the latter is not always financial (leaving family, adapting to a new environment, etc.). Moreover, we can wonder whether graduates employment prospects actually improve thanks to international mobility. Using the Céreq « Génération 98 » survey, our first results show that international mobility on entering the labour market appears to be rare. Final…
