Current status of non-metal clasp dentures

– What should we consider to select it for removable partial dentures? –

Abstract

Recently, consideration for aesthetics becomes more important for partially edentulous patients with removable partial dentures, so occasions to see patients wearing non-metal clasp dentures have increased. Although the Japanese Prosthodontic Society published the position paper showing clinical guidelines for using non-metal clasp dentures, there are still many unclear points, and there are a few cases where it is difficult to deal with correspondence after-insertion of the denture. In this paper, the thermoplastic resin materials for non-metal clasp denture were organized, and the present evidence and views on the effects of resin clasp on periodontal tissue were referred. Mechanism of retentive force and consideration of aesthetics were also referred. In addition, clinical attention points were described through basic cases.
