Effects of a local single dose administration of growth hormone on the osseointegration of titanium implants.
2021
The aim of the present study was to evaluate the effect of different concentrations of growth hormone (GH) on endosteal implant?s surface at the early stages of osseointegration. Sixty tapered acid-etched titanium implants were divided into four groups: i) Collagen, used as a control group; and three experimental groups, where after collagen coating, GH was administered directly to the surface in varying concentrations: ii) 0.265 mg, iii) 0.53 mg, and iv) 1 mg. Implants were placed in an interpolated fashion in the anterior flange of C3, C4 or C5 of 15 sheep with minimum distance of 6 mm between implants. After 3-, 6- and 12-weeks of healing samples were harvested, histologically processed,…
Estudio in vitro de la resistencia a la fractura mediante carga estática de materiales de restauración CAD-CAM para el sector posterior: influencia d…

RESUMEN DE TESIS DOCTORAL Doctoranda: Georgina García Engra Título de la Tesis: “Estudio in vitro de la resistencia a la fractura mediante carga estática de materiales de restauración CAD-CAM para el sector posterior: influencia del tipo de material y de la técnica de adhesión”. Introducción: El uso de restauraciones de recubrimiento parcial es una opción terapéutica que nos permite restablecer la función y estética del diente afecto mediante procedimientos de mínima invasión. En la actualidad, han surgido nuevos materiales de restauración para el sector posterior: cerámicas libres de metal y materiales híbridos. El tratamiento de estos materiales nos permite llevar a cabo técnicas de cemen…
Fracture Resistance of Partial Indirect Restorations Made With CAD/CAM Technology. A Systematic Review and Meta-analysis
2019
Background: The aim of this systematic review and meta-analysis was to determine the fracture resistance and survival rate of partial indirect restorations inlays, onlays, and overlays fabricated using computer-aided design and computer-aided manufacturing (CAD-CAM) technology from ceramics, composite resin, resin nanoceramic, or hybrid ceramic and to analyze the influence of proximal box elevation on fracture resistance. Materials and methods: This systematic review was based on guidelines proposed by the preferred reporting items for systematic reviews and meta-analyses (PRISMA). An electronic search was conducted in databases US National Library of Medicine National Institutes of Health …
Injertos óseos en bloque intraorales tipo onlay: estudio de los tejidos duros y blandos periimplantarios
2016
Los injertos óseos en bloque intraorales tipo onlay son una opción terapéutica para incrementar tanto la anchura como la altura del proceso alveolar para la posterior colocación de los implantes dentales. La colocación simultánea del implante con el injerto óseo permitiría acortar el tiempo de tratamiento y evitar un segunda cirugía, sin embargo aunque se ha descrito ampliamente en el aumento vertical, son escasos los estudios en el tratamiento del aumento horizontal. Por otro lado, diversos procedimientos se han utilizado para la atrofia vertical de los sectores posteriores de la mandíbula atrófica, sin embargo las complicaciones relacionadas con los procedimientos de aumento ha hecho que …
Clinical Behavior of Ceramic, Hybrid and Composite Onlays. A Systematic Review and Meta-Analysis
2020
A systematic review and meta-analysis was performed to analyze the survival of onlay restorations in the posterior region, their clinical behavior according to the material used (ceramic reinforced with lithium disilicate, conventional feldspathic ceramic or reinforced with leucite; hybrid materials and composite), possible complications, and the factors influencing restoration success. The systematic review was based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, without publication date or language restrictions. An electronic search was made in the PubMed, Scopus, Embase, and Cochrane databases. After discarding duplicate publications and stu…
