Estudio comparativo de la eficiencia y eficacia de las impresiones dentales digitales y las impresiones dentales convencionales.

Abstract

Taking impressions is a step in making a dental prosthesis. Various printing materials are used for conventional printing. Recently, intraoral scanners have emerged to obtain three-dimensional images without the need for materials and reducing the risk of error. The objective was to compare the efficiency and effectiveness of digital dental impressions and conventional dental impressions. A systematic review was developed in which 21 articles were included. The use of digital prints has advantages and disadvantages compared to conventional prints. The advantages are real-time visualization and evaluation, digital archiving, no waste of impression material, no use of trays, adhesives or plaster, and greater patient satisfaction. Its disadvantages would be the high initial cost of the equipment, difficult to capture occlusion information, it is difficult to capture the subgingival margins and images of the edentulous arches cannot be accurately captured. To take digital impressions, an intraoral scanner is required that captures the images in real time and allows them to be digitally stored. In conventional impressions, it is necessary to select the material, the tray, take the impression, perform the casting and only then is the model sent to the laboratory. The survival of prosthetic restorations made from digital impressions and conventional impressions is similar; the type of impression is not the main factor in the failure or success of the restorations.
