RESUMEN

La implantología oral clínica ha evolucionado significativamente durante las últimas décadas. El desarrollo de los aspectos diagnósticos, quirúrgicos y prostodóncicos ha mejorado la predictibilidad de la oseointegración y los resultados clínicos a largo plazo del tratamiento con implantes. Además, algunos criterios de condiciones clínicas y radiográficas se han incorporado al concepto de éxito, como el nivel de los implantes, los tejidos periimplantarios, el nivel de la prótesis y el grado de satisfacción de los pacientes. La evidencia científica ha demostrado que el tratamiento con implantes es una excelente opción para la rehabilitación de los pacientes con parcial y total edentulismo. De hecho, los estudios a largo plazo reflejan el éxito de las rehabilitaciones fijas, sobredentaduras, puentes fijos y coronas unitaria. Sin embargo, algunas complicaciones biológicas y prostéticas han definido los conceptos diferentes de éxito y supervivencia de los implantes dentales. Conclusiones: Este trabajo indica que las restauraciones sobre implantes dentales en la rehabilitación de los pacientes parcial y totalmente edéntulos constituye un tratamiento odontológico con resultados clínicos a largo plazo con un elevado éxito.

Clinical implant dentistry has evolved significantly during last decades. The development of diagnostic, surgical and prosthetic aspects has improved the predictability of osseointegration and long-term clinical outcomes of the implant treatment. Moreover, several criteria of clinical and radiographic conditions have been incorporated in the concept of implant success, as implant level, peri-implant tissues, prosthetic level, and patient satisfaction. The scientific evidence of the literature demonstrates that implant treatment is an excellent option for the rehabilitation of patients with partial and total edentulism. In fact, long-term studies are reported the success of fixed total rehabilitation, overdentures, fixed bridges and single crowns. However, some biological and technical complications are defined the different concepts of success and survival of prosthetic and dental implants. Conclusions: This paper indicates that restorations with dental implants in the rehabilitation of partially and totally edentulous patients constitute a dental treatment with long-term clinical outcomes with a high success.

RESUMEN

The intentional translocation of animals is an important tool for species conservation and ecosystem restoration, but reported success rates are low, particularly for threatened and endangered species. Publication bias further distorts success rates because the results of successful translocations may be more likely to be published than failed translocations. We conducted the first comprehensive review of all published and unpublished translocations of herpetofauna in New Zealand to assess publication bias. Of 74 translocations of 29 species in 25 years, 35 have been reported in the published literature, and the outcomes of 12 have been published. Using a traditional definition of success, publication bias resulted in a gross overestimate of translocation success rates (41.7% and 8.1% for published and all translocations, respectively), but bias against failed translocations was minimal (8.3% and 6.8%, respectively). Publication bias against translocations with uncertain outcomes, the vast majority of projects, was also strong (50.0% and 85.1% for published and all translocations, respectively). Recent translocations were less likely to be published than older translocations. The reasons behind translocations were related to publication. A greater percentage of translocations for conservation and research were published (63.3% and 40.0%, respectively) than translocations for mitigation during land development (10.0%). Translocations conducted in collaboration with a university were more frequently published (82.7% and 24.4%, respectively). To account for some of this publication bias, we reassessed the outcome of each translocation using a standardized definition of success, which takes into consideration the species' life history and the time since release. Our standardized definition of translocation success provided a more accurate summary of success rates and allows for a more rigorous evaluation of the causes of translocation success and failure in large-scale reviews.

RESUMEN

Actualmente los implantes dentales oseointegrados constituyen una alternativa terapéutica para la restauración de los dientes perdidos por diferentes causas. La aparición de múltiples sistemas de implantes y su uso en la población hace necesario el empleo de un grupo de criterios para poder predecir el éxito o fracaso de las restauraciones implantosoportadas. Cada paciente debe conocer los riesgos y beneficios del procedimiento así como una predicción del tiempo de vida de la restauración implantosoportada. La aplicación clínica de algunos parámetros e índices dan sustento a la utilización adecuada de los criterios de éxito y fracaso

At the moment osseointegrated dental implants constitute a therapeutic alternative for the restoration of the lost teeth by different causes. The appearance of multiple systems of dental implants and its use in the population makes the use necessary of a group of criteria to be able to predict the success or failure of the implant-supported restorations. Each patient must know the risks and benefits the procedure as well as a weather forecast of life of the implant-supported restoration. The clinical application of some parameters and indices gives to sustenance to the suitable use of the success criteria and failure
