Maxillary sinus lift without grafting, and simultaneous implant placement: a prospective clinical study with a 51-month follow-up

A prospective clinical study of maxillary sinus lift procedures in the posterior region of the maxilla, using only blood clot as filling material, was conducted. Seventeen patients underwent a maxillary sinus lift procedure; 20 maxillary sinus regions were operated on and a total of 25 implants were placed. The sinus mucosa was lifted together with the anterior wall of the osteotomized maxilla and supported by the implants placed. Computed tomography (CT) scans were obtained immediately postoperative (T-initial) and at 3 (T-1) and 51(T-2) months postoperative for the measurement of linear bone height and bone density (by grey tones). Only one implant was lost in the first stage (96% success). After dental prosthesis placement and during up to 51 months of follow-up, no implant was lost (100% success, second stage). The difference in mean bone height between T-initial (5.94 mm) and T-1 (13.14 mm), and between T-initial and T-2 (11.57 mm), was statistically significant (both P < 0.001); comparison between T-1 and T-2 also presented a statistical difference (P < 0.001). Bone density had increased at the end of the period analyzed, but this was not statistically significant (P > 0.05). Thus, the maxillary sinus lift technique with immediate implant placement, filling with blood clot only, may be performed with a high success rate.

Quality management, environmental management maturity, green supply chain practices and green performance of Brazilian companies with ISO 14001 certification: Direct and indirect effects (Reprint from vol 67C, pg 39-51)

This study aims to test a new conceptual model based on the relationship between quality management (QM), environmental management maturity (EMM), adoption of external practices of green supply chain management (GSCM) (green purchasing and collaboration with customers) and green performance (GP) with data from 95 Brazilian firms with ISO 14001. To our knowledge, such links and relationships are not simultaneously identified and tested in the literature. The results indicate the validation of all of the research hypotheses. This paper highlights that an improvement in green performance will require attention to quality management, environmental management maturity, and green supply chain.

Resolución de "pequeños" conflictos en zonas de "grandes" conflictos. Una aproximación desde la antropología a las nociones endógenas de paz en Casamance (Senegal)

[ES] A menudo, las grandes instituciones internacionales aplican políticas de resolución de conflictos a gran escala sin fijarse en los sistemas y estrategias endógenos de las poblaciones implicadas. En este artículo intentaremos presentar algunos valores, prácticas e instituciones locales que intentan resolver conflictos de todo tipo a pequeña escala en la región de Casamance, donde se vive uno de los conflictos más duraderos del continente africano. Para ello, presentamos los diferentes grupos étnicos que habitan en Casamance y algunas de sus instituciones más características a la hora de mediar entre familias, pueblos o comunidades. Y finalmente invitamos a reflexionar sobre si estas estrategias endógenas podrían ser utilizadas de forma coordinada como contribución al proceso de paz en Casamance.
