Digital Impression in Prosthodontics: A Review

Abstract

Digital impression technology is transforming prosthodontics by enhancing the accuracy, efficiency, and patient comfort in the creation of dental prostheses. This technology captures precise 3D images of dental structures, facilitating the design and fabrication of various prostheses through CAD/CAM systems. In complete dentures, digital impressions ensure accurate representation of edentulous arches, leading to better-fitting prosthetics. For removable partial dentures, they streamline the design and production process, providing a precise fit for metal frameworks and prosthetic teeth. Fixed partial prostheses benefit from detailed digital scans of prepared teeth, allowing for the creation of crowns and bridges with optimal margins and occlusion. In maxillofacial prosthetics, digital impressions capture facial structures accurately, enabling the creation of custom prostheses that match the patient's anatomy. Implant-supported prostheses use digital impressions combined with CBCT data to design custom abutments and prosthetics, ensuring precise placement and fit. Overall, digital impressions in prosthodontics improve accuracy, reduce chair time, and enhance patient outcomes, representing a significant advancement in dental care.
