Este trabajo tiene como objetivo general determinar los efectos que produce la oclusión dentaria en el alineamiento de las vértebras cervicales con relación al plano SN mediante el uso de una guía oclusal. Respecto a la metodología fue explicativo, transversal y pre experimental; para la obtención de datos se utilizó una guía oclusal por una semana y un radiografía cefalometrica antes y después del uso del dispositivo oclusal para medir la nueva posición de las vértebras a nivel de la apófisis odontoides de la segunda vertebra cervial tanto angular y lineal en relación al plano SN. La muestra fue de un grupo de estudio de 10 estudiantes. Entre los resultados obtenidos se puede observar que el ángulo formado por el eje de la apófisis odontoides (C2) y el plano S-N al cual denominaremos ángulo SN-O, en oclusión habitual en promedio es de 93,35 ° y en relación céntrica ...

Objectives: To determine in vitro if there is a difference in the marginal microfiltration of composite resin inlays, cemented with dual resin cement and fluidized composite by preheating, evaluated with macrophotographs at the Private University of Huancayo Franklin Roosevelt 2018 - 2019. Material and Methods: In vitro experimental type, quasi-experimental design. Results: It was found that of the inlays cemented with dual resin cement and with fluidized composite resin, they presented the highest percentages: 80% and 70% respectively at the “medium level of microleakage”, in terms of “absence of microleakage”, the fluidized resin had 5% as opposed to 0% of dual cement, and the “high microleakage” level was present only in the 10% dual cement cemented inlays and both equaled 0% in “very high” grade microleakage. Noting a slight superiority in terms of the lower presence ...
