Published writings from 1994 to 2022 were obtained, examined, and relevant articles were chosen for this review. The online databases were used to perform a literature search for publications published until 2022, without any date or language restrictions. We used a combination of relevant search terms, such as “acetal resin, esthetic restoration, dentistry, esthetic clasp, poly (oxyethylene), removable partial denture”.
