COMPARISON OF THE DIGITAL TECHNIQUE USING THE CAD/CAM SYSTEM AND CONVENTIONAL IMPRESSIONS

COMPARISON BETWEEN CAD/CAM SYSTEM AND CONVENTIONAL IMPRESSIONS.

Abstract

This study aimed to compare the digital impression technique using the CAD/CAM system with conventional impression methods in dentistry through a bibliographic review of updated scientific literature. Introduction: Dental impressions are a fundamental procedure in restorative dentistry, where accuracy determines the quality and longevity of restorations. The introduction of digital systems has transformed traditional clinical workflows. Objective: To comparatively analyze the accuracy, efficiency, and clinical applicability of digital versus conventional impressions. Materials and Methods: A qualitative bibliographic review was conducted using specialized databases such as SciELO, Google Scholar, Hindawi, ResearchGate, and DSpace. Twenty-four publications from 2015 to 2025 in Spanish, English, and Portuguese were selected, focusing on dimensional accuracy, operative efficiency, and clinical performance of both methods. Results: Findings indicate that digital impressions optimize workflow, enhance patient comfort, and facilitate efficient data management. However, their accuracy depends on factors such as operator experience, scanner type, and scanning protocol. Conventional techniques, although more time-consuming and prone to error, remain reliable and widely used in clinical practice. Conclusions: Both methods demonstrate relevant clinical value. Digital impressions using CAD/CAM stand out for their precision, efficiency, and adaptability, while conventional impressions continue to be essential where technological resources are limited. The choice of technique should depend on the clinical case, available resources, and practitioner expertise.
