“…Meyer et al (1973), Baliga et al (1992), and Starke et al (1997). Other studies have predicted a maximum rise of 45-501C (Huiskes, 1980), 401C (Baliga et al, 1992), and 36-451C (Starke et al, 1997).…”

“…Therefore, in his model, all regions of cement polymerised at the same rate, and this may lead to inaccuracies in the timing and magnitude of the maximum temperature. This was noted by Huiskes (1980) when comparing predictions of his model with results from an experimental study by Meyer et al (1973). Baliga et al (1992) developed an empirical model for the prediction of heat generation in polymerising cement as a function of temperature and fraction of monomer polymerised.…”

“…La reacción de polimerización que ocurre en los cementos óseos durante el proceso de fraguado es exotérmica y el calor desprendido es de 54,4 kJ.mol -1 . [8] Se conoce que los altos calores de polimerización pueden causar necrosis del tejido en los alrededores de la prótesis y además puede afectar severamente la durabilidad del implante debido a que induce la reabsorción del tejido óseo y produce aflojamiento de la prótesis. [9] El estudio de la bioactividad in vitro es un ensayo importante a valorar en este tipo de biomateriales.…”

“…[9] El estudio de la bioactividad in vitro es un ensayo importante a valorar en este tipo de biomateriales. [8] Su determinación se fundamentan en el hecho de que en los materiales cerámicos que se enlazan directamente al hueso se ha podido demostrar que las primeras etapas del mecanismo de enlace pueden simularse en un medio inorgánico, sin presencia de células, siempre y cuando dicho medio contenga los iones necesarios para que el material pueda desarrollar una nueva fase tipo carbonato-hidroxiapatita (CHA) en su superficie.…”

Resumen: Los cementos óseos se han convertido en los últimos años en biomateriales de gran utilidad en la fijación de prótesis y en la reconstrucción del hueso. El objetivo de este trabajo es evaluar las propiedades termoanalíticas tales como temperatura máxima de polimerización y tiempo de fraguado en cementos óseos acrílicos modificados con hidroxiapatita/ acetato de vinilo, determinar la resistencia a la compresión axial y realizar ensayos de bioactividad in vitro. Diferentes contenidos de acetato de vinilo fueron incorporados en cementos óseos acrílicos cargados todos con un 30 % de hidroxiapatita CORALINA ® HAP-200. Las propiedades mecánicas y los parámetros de curado fueron evaluados cumpliendo lo establecido en la Norma ISO 5833 descrita para cementos óseos acrílicos. Se determinaron los parámetros termoanalíticos, obteniéndose tiempos de fraguados entre 3 y 6 minutos y los valores de temperaturas máximas de polimerización oscilan entre 66 y 88 °C. Se obtuvo formulaciones con valores de resistencia a la compresión superiores a lo establecido en la Norma ISO 5833. Se demostró la bioactividad de las formulaciones mediante la inmersión de las muestras en fluido biológico simulado, observándose en la superficie de las mismas la nucleación y el crecimiento de cristales con morfología similar a las apatitas biológicas. Palabras-clave: Cementos óseos acrílicos, hidroxiapatita, tiempo de fraguado, resistencia a la compresión. Acrylic Bone Cement Modified whit Hydroxiapatyte/Vinyl Acetate. Mechanical, Thermoanalytical Characterization and In Vitro BioactivityAbstract: Bone cements have become biomaterials of great utility in the prosthesis fixation and as substitutes to the bone. The objective of this study is to evaluate the thermo analytical properties such as setting time and peak temperature of polymerization of acrylic bone cement modified with hydroxyapatite/vinyl acetate, to determine the compression strengths and perform in vitro bioactivity tests. Amounts of vinyl acetate component were incorporated in different percentages in acrylic bone cements, all loaded with 30 % of hydroxyapatite CORALINA ® HAP-200. Curing parameters and mechanical properties were determined finding formulations that comply with the ISO 5833 norm. In vitro bioactivity tests were performed in two cement formulations. The setting time obtained ranged between 3 and 6 minutes and the peak temperature varied between 66 and 88 °C. Compression strengths were higher than established in the ISO 5833 regulation for mechanical properties evaluation of acrylic bone cements. The bioactivity was demonstrated by immersion of the samples in simulated body fluid, in which nucleation and crystal growth were observed on the sample surface with similar morphology and composition to biological apatite.
