Abstract

A combined short arm clasp for removable partial denture is arranged on two adjacent abutments (6). The combined short arm clasp for removable partial denture is characterized by comprising two cheek clasp arms (1), a clasp body (2), a rest (3), a small connector (4) and a tongue side antagonist (5) that are connected successively; the two cheek clasp arms (1) are connected with the clasp body (2) in a herringbone shape; elastic parts of the two cheek clasp arms (1) are arranged in gum embrasure between the two abutments (6); and tips of the cheek clasp arms (1) are lower than cheek axial ridge. On the premise of no damage on effects of retention, support and stabilization, the combined short arm clasp can reduce and eliminate expose of metal parts of the cheek clasp arms and improve aesthetic property of the denture.
