Growing evidence has suggested the utility of short dental implants for oral reconstructive procedures in clinical situations of limited vertical bone height. The aim of this review was to systematically evaluate clinical studies of implants < 10 mm in length, to determine short implant-supported prosthesis success in the atrophic jaw. Implant survival, incidence of biological and biomechanical complications, and radiographic peri-implant marginal bone loss were evaluated. Screening of eligible studies, quality assessment, and data extraction were conducted by two reviewers independently. Meta-analyses were performed by the pooling of survival data by implant surface, surgical technique, implant location, type of edentulism, and prosthetic restoration. Two randomized controlled trials and 14 observational studies were selected and analyzed for data extraction. In total, 6193 short-implants were investigated from 3848 participants. The observational period was 3.2 ± 1.7 yrs (mean ± SD). The cumulative survival rate (CSR) was 99.1% (95%CI: 98.8-99.4). The biological success rate was 98.8% (95%CI: 97.8-99.8), and the biomechanical success rate was 99.9% (95%CI: 99.4-100.0). A higher CSR was reported for rough-surfaced implants. The provision of short implant-supported prostheses in patients with atrophic alveolar ridges appears to be a successful treatment option in the short term; however, more scientific evidence is needed for the long term.

Resumen El propósito de la investigación fue la exploración de factores emocionales en adolescentes que presentan obesidad y a raíz de los hallazgos encontrados hacer recomendaciones psicoterapéuticas. Para conocer la vida emocional y las relaciones significativas de estos adolescentes se aplicaron cuatro instrumentos diagnósticos: Entrevista clínica, TRO, PBI y OQ45, a dos grupos de adolescentes con y sin diagnóstico de obesidad, grupo de estudio y grupo de control respectivamente, con un n= 25. Los resultados de esta investigación muestran que los adolescentes obesos presentan tanto sintomatología psíquica, ansiedad y depresión, como una dificultad en la tolerancia y manejo de afectos intensos relacionada con fallas anteriores provenientes del contexto parental.
