Comparative fracture behavior of monolithic and veneered zirconia posterior fixed dental prostheses
2017
The purpose of this study was to evaluate and to compare the fracture load and the fracture pattern of monolithic and veneered zirconia posterior fixed dental prostheses (FDPs). Twenty standardized steel dies were prepared to receive posterior 3-unit FDPs. Specimens were randomly divided into 2 groups (n=10): (1) Lava Zirconia, and (2) Lava Plus. All FDPs were cemented using glass ionomer cement and subjected to thermal and mechanical cycling at 5-55ºC with a 30-s dwell time for 120,000 masticatory cycles. All specimens were subjected to a three-point bending test until fracture. Data were statistically analyzed using Student's t test, paired t-test and Weibull statistics (α=0.05). No diffe…
Fracture resistance and failure mode of posterior fixed dental prostheses fabricated with two zirconia CAD/CAM systems.
2014
Background In recent years there has been an improvement of zirconia ceramic materials to replace posterior missing teeth. To date little in vitro studies has been carried out on the fracture resistance of zirconia veneered posterior fixed dental prostheses. This study investigated the fracture resistance and the failure mode of 3-unit zirconia-based posterior fixed dental prostheses fabricated with two CAD/CAM systems. Material and Methods Twenty posterior fixed dental prostheses were studied. Samples were randomly divided into two groups (n=10 each) according to the zirconia ceramic analyzed: Lava and Procera. Specimens were loaded until fracture under static load. Data were analyzed usin…
Tratamiento de la mastoiditis aguda en niños con implante coclear
2010
Resumen Introduccion La mastoiditis aguda es una complicacion infecciosa otitica que plantea una problematica especifica en el caso de pacientes implantados. Objetivo Revisar los casos de mastoiditis aguda en el programa de implantes cocleares para valorar su incidencia y los problemas asociados. Materiales y metodos Se realizo un estudio retrospectivo en 248 ninos implantados con edades entre los 8 meses y 14 anos desde 1994 hasta 2009 en nuestro programa de implantes cocleares. Se analizan los datos demograficos, clinicos y su tratamiento. Resultados Cinco pacientes desarrollaron mastoiditis aguda (incidencia de 2,01%), 3 de ellos con absceso subperiostico (incidencia de 1,21%), La edad m…
Treatment of acute mastoiditis in children with cochlear implants
2009
Abstract Introduction Acute mastoiditis (AM) is a paediatric infectious complication that raises a specific problem in case of implanted patients. Objective To review the cases of AM in a paediatric cochlear implant (CI) programme to study its incidence and associated problems. Materials and methods A retrospective study was conducted on 248 children aged between 8 months and 14 years who underwent CI from 1994 to 2009. The demographics, clinical data and their treatment were analyzed. Results Five patients developed acute mastoiditis (2.01%), three of them with subperiosteal abscess (1.21%). The mean age of implantation was 2 years and 4 months, and the complication presented between 1 and…
