Resumen
En el transcurso de los años, la toma de impresión definitiva en un paciente edéntulo total ha sido todo un reto para el profesional odontólogo, debido a la variación de sus estructuras anatómicas que dificulta esta maniobra y por ende el resultado final de nuestra impresión bucal. A pesar de tener a disposición una gran variedad de materiales elaborados exclusivamente para este fin, y las experiencias recaudadas por diferentes profesionales rehabilitadores, nos dimos cuenta de que cada uno de ellos tenían cierta predilección por un material en específico. Por lo cual se plantea la interrogante de saber cuál de estos materiales se acerca más a la expectativa de un material ideal destacando la importancia del conocimiento de las propiedades físicas y químicas de dichos materiales con el fin de compararlos entre sí y llegar a una conclusión. Para este cometido se ha utilizado la modalidad bibliográfica, recopilando información pertinente de diversos artículos y revistas científicas las cuales nos orientaron hacia dos materiales en específico, que son: la pasta zinquenólica y las siliconas, las cuales, a pesar de ser muy diferentes, demostraron ofrecer resultados similares en cuanto a la reproducción de detalles anatómicos. Sin embargo, considerando otros factores como la manipulación, el tiempo de fraguado, estabilidad dimensional, entre otras, concluimos que la silicona de adición de consistencia regular es el material de impresión definitiva que se asemeja más a la expectativa de material de impresión ideal.
In the course of the years, the capture of definitive impression in a patient without teeth has been a challenge for the professional odontologist, due to the variation of their anatomical structures that make difficult this maneuver and, at last, the final result of our buccal impression. In spite of having a great variety of materials elaborated exclusively for this end, and the experiences collected by different professionals, we realized that each of them had certain predilection for a material in specific. For which the question is which of these materials approaches more the expectation of an ideal material emphasizing the importance of the knowledge of the physical and chemical properties in order to compare them and to come to a conclusion. For this assignment the bibliographical modality has been in use, compiling pertinent information of diverse articles and scientific magazines which orientated us towards two materials in specific, which are: the zinquenolic paste and the silicones, which, in spite of being very different, demonstrated to offer similar results for the reproduction of anatomical details. Nevertheless, considering other factors as the manipulation, the time of plotted, dimensional stability, among others, we conclude that the silicone of addition of regular consistency is the material of definitive impression that is close to the expectation of the ideal material impression.
