Este movimiento es del orden de 5 billones de veces por segundo y produce millones de colisiones intermoleculares, causando un calentamiento uniforme. Es ese calentamiento que proporciona la polimerizaci\u00f3n de la resina acr\u00edlica y la reducci\u00f3n del mon\u00f3mero residual a niveles insignificantes,\u00a0 produciendo una pr\u00f3tesis perfecta y dimensionalmente estable.<\/p>\n<p>Para el descerado de una mufla con una pr\u00f3tesis total se puede usar la secuencia:<\/p>\n<ul>\n<li>Potencia<span> 70\u00a0<\/span><\/li>\n<\/ul>\n<ul>\n<li>Tiempo      <span>1 <\/span>minuto<\/li>\n<\/ul>\n<p><!--[if gte mso 9]&amp;gt;
