New Modes of Regulation for Health and Safety: Post-Enlargement Policy Perspectives for the European Union
2006
The recent joining of ten new member states to the European Union, eight of which are former communist countries, has reopened inherent tensions in current European Union (EU) policy-making on safety and health in the workplace. These spring from seemingly incompatible objectives; the need to ensure broad EU member state compliance with regulation, around agreed minimum standards through active regulatory enforcement, and the promotion of “softer” voluntary initiatives in the management of workplace risks and hazards in order to create “a culture of prevention.” The present EU strategy which ends in 2006, seeks to secure a balance between both sets of objectives. However, with respect to t…
Bone-to-implant contact of orthodontic implants in humans--a histomorphometric investigation
2008
The purpose of the present study was to evaluate the percentage of direct bone-to-implant contact (BIC) of orthodontic anchorage implants (Orthosystem) after active orthodontic treatment. Twenty orthodontic implants (diameter, 3.3 mm; length, 4 or 6 mm) were inserted for orthodontic anchorage in different anatomical regions of 18 adult patients (nine males, nine females) aged 18-63 years. Fifteen implants (one per patient) were placed in the mid-palatal area, one implant (one patient) in the retromolar area of the mandible, one in the retromolar area and the mid-palatal area (one patient), and two (bilaterally, one patient) in the zygomatic area. The duration of the unloaded healing period …
Vertical Mandibular Alveolar Bone Distraction and Dental Implant Placement: A Case Report
2006
Abstract Extensive bone defects complicate the adequate placement of dental implants and the required angulation. In such cases, alveolar-ridge augmentation techniques such as guided bone regeneration, particulate or block grafting, and alveolar bone distraction are needed. The present study describes a case in which a large vertical bone defect in the anterior mandibular zone was corrected via vertical alveolar bone distraction. Six dental implants were posteriorly placed for implant-supported restoration of the mandible, with early implant loading. The clinical and radiologic control showed good implant and soft tissue conditions 12 months later.
Effect of undersized drilling on the stability of immediate tapered implants in the anterior maxillary sector. A randomized clinical trial.
2020
Background To evaluate the effect of undersized drilling on the primary and secondary stability of immediate implants placed in the anterior maxilla. Material and Methods A comparative randomized clinical trial was carried out in 30 healthy adults. Thirty tapered implants, 16 involving conventional drilling and 14 undersized drilling, were placed immediately after anterior maxillary tooth removal. Insertion torque and implant stability assessed by resonance frequency analysis (RFA) were evaluated at three different timepoints: at implant placement and 6 and 12 weeks post-implantation. The results were compared using parametric statistical tests. Results All implants showed adequate stabilit…
Goal Construction, Reconstruction and Depressive Symptoms in a Life-Span Context: The Transition From School to Work
2002
This study focused on investigating the kinds of personal goals young adults have when they are faced with the transition from school to work; the extent to which they reconstruct these goals as a consequence of their success in dealing with this transition; and how their goals influence their depressive symptoms. In order to investigate these research questions, 250 young adults who were facing a transition from school to work were studied at three points of the transition process: while they were still at school; 8 months after their graduation; and 1.5 years after it. At each measurement point, they were asked to complete the Personal Project Analysis, a revised form of Beck's Depression…
Ability for Voice Recognition Is a Marker for Dyslexia in Children
2014
A recent voice recognition experiment conducted by Perrachione, Del Tufo, and Gabrieli (2011) revealed that, in normal adult readers, the accuracy at identifying human voices was better in the participants’ mother tongue than in an unfamiliar language, while this difference was absent in a group of adults with dyslexia. This pattern favored a view of dyslexia as due to “fundamentally impoverished native-language phonological representations.” To further examine this issue, we conducted two voice recognition experiments, one with children with/without dyslexia, and the other with adults with/without dyslexia. Results revealed that children/adults with dyslexia were less accurate at identify…
External and internal facial features modulate processing of vertical but not horizontal spatial relations.
2019
Some years ago an asymmetry was reported for the inversion effect for horizontal (H) and vertical (V) relational face manipulations (Goffaux & Rossion, 2007). Subsequent research examined whether a specific disruption of long-range relations underlies the H/V inversion asymmetry (Sekunova & Barton, 2008). Here, we tested how detection of changes in interocular distance (H) and eye height (V) depends on cardinal internal features and external feature surround. Results replicated the H/V inversion asymmetry. Moreover, we found very different face cue dependencies for both change types. Performance and inversion effects did not depend on the presence of other face cues for detecting H changes.…
Mandibular connective tissue pedicle flaps in implant dentistry: report of three cases.
2007
Abstract An increase in soft tissues and alveolar bone in the anterior mandibular area between the canines is necessary to achieve a good esthetic result. The present article describes a technique for gaining bone volume and soft tissue to cover bone defects that would otherwise compromise the final result of prosthetic implant restoration in the anterior mandible. Three patients with anterior mandibular atrophy caused by loss of the mandibular incisors are presented. Particulate autologous bone grafting, the raising of a pediculate connective tissue flap to increase soft tissue, and implant placement were carried out simultaneously. After 2 years of follow-up, the implants were in good cli…
Vertical guided bone regeneration with bioabsorbable barriers.
2007
Guided bone regeneration (GBR) is a very useful surgical technique to increase limited alveolar bone for implant placement. The use of non-resorbable barriers is well established; however, bioabsorbable collagen membranes may simplify the surgical technique and make it more predictable.Vertical ridge augmentation was performed on 11 patients at the time of implant placement. The part of the implant out of bone was covered with autogenous bone/graft, and a slow-resorption collagen membrane was placed on top. Gingival tissues were closed with horizontal mattress and interrupted sutures. Second-stage surgery was performed 4 to 6 months later, and healing abutments were placed. The length of th…
Use of autologous tooth-derived graft material in the post-extraction dental socket. Pilot study
2019
Background The objectives of the present pilot study are to compare via CBCT the alveolar contraction suffered both vertically and horizontally between the control group and the group using autologous dental material (ADM), as well as to study the densitometric differences between both post-extraction sockets. Material and Methods A split-mouth study was performed in n = 9 patients who required two extraction of single-rooted teeth deemed suitable for deferred rehabilitation with osseointegrated implants. Two groups were formed — a control group, in which the post-extraction socket was not filled, and an ADM group, in which the alveolar defect was filled with freshly processed autogenous de…
