Since the 1930’s, partial denture frameworks have generally been made from metallic alloys such as Cobalt-Chromium (Co-Cr). However, the main limitations of these materials are related to their aesthetics, due to which there is a lack of patient acceptance. The introduction of thermoplastic polymers like polyamide, polyoxymethylene, and the aryl ketone family has been revolutionary due to their good mechanical properties, excellent aesthetics, and adequate biocompatibility. While their usage has seen an exponential increase in recent times, adequate research regarding their long-term clinical success is limited, especially regarding the recently introduced PEEK and PEKK. The current review aims to briefly discuss the types of polymeric partial denture frameworks along with their advantages and disadvantages.
