A Comparative Analysis of the Marginal Fit of Fixed Prostheses Fabricated Using Digital and Conventional Workflows

Abstract

Objective: To analyze marginal fit in fixed prostheses using digital and conventional workflows, treatment success and longevity, preparation techniques, and materials used, as well as professional skills and methods. Literature Review: Marginal fit is one of the most complex aspects of a prosthesis, regardless of whether it is fabricated using a digital or conventional workflow. Success and longevity depend on the preparation technique used, the dentist’s skill, and the materials used for fabrication. Conversely, problems related to poor marginal adaptation can lead to periodontal disease, marginal infiltration, and potentially malignant conditions. Conclusion: There are various methods for achieving marginal adaptation using restorative materials, laboratory analyses, and clinical assessments; however, even with the use of these current methods, there are still issues that reflect a failure to achieve proper adjustments in the cervical region tailored to each patient’s specific case. The importance of this adaptation implies o enhance the protection of dental structures against caries, gum disease, infiltration, and potentially malignant oral diseases
