Abstract
Prosthetic margin design is one of the most critical determinants of periodontal tissue health and the long-term success of fixed dental restorations. Incorrect margin placement or poor marginal adaptation can lead to plaque accumulation, gingival inflammation, violation of the biological width, periodontal attachment loss, and eventual failure of the restoration. This article provides a comprehensive analysis of the influence of prosthetic margin design on periodontal tissues, focusing on biological principles, clinical considerations, restorative materials, and periodontal responses. Through evaluation of margin location, configuration, and material properties, the study emphasizes that biologically oriented prosthetic planning significantly improves gingival health, reduces inflammatory complications, and enhances the durability and predictability of prosthetic treatment outcomes.
