Resumen
Las impresiones digitales intraorales es la creación de un modelo tridimensional de las preparaciones dentarias y demás tejidos adyacentes dentro de la cavidad oral, se realiza mediante un escáner intraoral, además es una variante moderna y compensatoria en los cambios volumétricos producidos con las impresiones analógicas que son una fuente de error en la adaptación marginal de las restauraciones protésicas fijas. El objetivo de este estudio es analizar la precisión de las impresiones digitales intraorales en la actualidad. La metodología usada fue de carácter cualitativo y documental ya que la bibliografía proporciono toda la información requerida para este estudio el método utilizado fue deductivo - inductivo, porque la literatura científica actualizada fue quien brindó todo el marco conceptual de definiciones, y protocolos de elaboración de las PPR y demás información acerca del tema. Los resultados fueron que: las impresiones digitales intraorales son más precisas que las extraorales ya que son tomadas directamente de la boca del paciente y no de un modelo de estudio que ha sido realizado artesanalmente por tal motivo las restauraciones tendrán mejor pronostico. Concluyendo: que las prótesis parciales fijas realizadas con escaneo digital intraoral resultaron tener una brecha marginal inferior a las realizadas con impresiones análogas, y están dentro del rango clínicamente aceptable (120 micras).
Intraoral digital impressions is the creation of a three-dimensional model of dental preparations and other adjacent tissues within the oral cavity, it is performed by an intraoral scanner, it is also a modern and compensatory variant in the volumetric changes produced with analog prints that are a source of error in the marginal adaptation of fixed prosthetic restorations. The aim of this study is to analyze the accuracy of intraoral digital impressions today. The methodology used was qualitative and documentary since the bibliography provided all the information required for this study the method used was deductive - inductive, because the updated scientific literature was the one that provided the entire conceptual framework of definitions, and protocols for the elaboration of the PPR and other information on the subject. The results were that: intraoral digital impressions are more accurate than extraoral ones since they are taken directly from the patient's mouth and not from a study model that has been carried out by hand for this reason the restorations will have better prognosis. Concluding: that fixed partial prostheses performed with intraoral digital scanning turned out to have a lower marginal gap than those performed with analogous impressions which are within the clinically acceptable range (120 microns).
