Biologic periodontal/mucosal base of the prosthesis • Prosthetic base - abutments, proc. alveolaris mucosa, hard palate

Components of a removable partial denture • Prosthetic plate (bar) – major connector • Tooth-carrying denture bases – saddle • Masticatory complex – artificial teeth • Retainers • Connecting components – minor connectors
