clasp

(klasp),
1. A part of a removable partial denture that acts as a direct retainer or stabilizer for the denture by partially surrounding or contacting an abutment tooth.
2. A direct retainer of a removable partial denture, usually consisting of two arms joined by a body that connects with an occlusal rest; at least one arm of a clasp usually terminates in the infrabulge (gingival convergence) area of the tooth enclosed.

clasp

(klasp) a device to hold something.

clasp,

n an extracoronal direct retainer of a removable partial denture, usually consisting of two arms, a retentive arm and a reciprocal arm, joined by a body that may connect with an occlusal rest.
clasp, Adams,
n.pr a formed wire clasp of modified arrowhead design using the buccomesial and distoproximal undercuts of a tooth for retention.
clasp, arm,
n the clasp extensions, usually from minor connectors, that provide retention, reciprocation, or stabilization.
clasp, arm, fatigue of,
n a situation in which the retentive arm of a clasp metal has undergone flexure at the same point repeatedly, and fracture has resulted. Tapering the clasp arm tends to distribute the flexure and reduce such tendency to fracture.
clasp, arm, reciprocal,
n an arm of a clasp, usually at or occlusal to the height of contour, located in such a manner as to reciprocate any force arising from an opposing clasp arm on the same tooth.
clasp, arm, retentive (retention terminal),
n a clasp arm that is flexible and engages the infrabulge area at the terminal end of the arm.
clasp, arrowhead,
n a wire clasp, for retention of removable appliances, whose active elements are in the shape of an arrowhead and engage the mesioproximal and distoproximal undercuts on the buccal aspects of adjacent teeth.
clasp, back-action,
n a clasp that originates on one surface of a tooth and traverses the suprabulge area to another surface, where it is supported by an occlusal rest; it then continues to encircle the tooth on the third surface, where it terminates in the infrabulge area beyond the opposite angle of the tooth surface where it originated.
clasp, bar,
n a clasp with arms that are bar-type extensions from major connectors or from within the denture base; the arms pass adjacent to the soft tissues and approach the point of contact on the tooth in a cervicoocclusal direction.
clasp, bar, arm,
n a clasp arm that originates from the denture base or from a major or minor connector. It consists of the arm, which traverses but does not contact the gingival structures, and a terminal end, which approaches its contact with the tooth in a cervicoocclusal direction.
clasp, cast,
n a clasp made of an alloy that has been cast into the desired form and retains its crystalline structure.
clasp, circumferential
n a clasp that encircles more than 180° of a tooth, including opposite angles, and usually contacts the tooth throughout the extent of the clasp, at least one terminal being in the infrabulge area (cervical convergence).
clasp, circumferential arm,
n a clasp arm that has its origin in a minor connector and follows the contour of the tooth approximately in a plane perpendicular to the path of placement of the removable partial denture.
clasp, combination,
n a clasp that employs a wrought-wire retentive arm and a cast reciprocal or stabilizing arm. A clasp that employs a bar type of retentive arm and a cast reciprocal or stabilizing arm.
clasp, continuous,
n a secondary lingual bar.
clasp design,
n the determination of the shape and construction of a clasp with its position outlined on the cast.
clasp, embrasure
n a clasp used where no edentulous space exists. It passes through the embrasure, using two occlusal rests, and clasps the two teeth with circumferential clasps that have a common body.
clasp flexibility,
n the property of a clasp that enables it to be bent without breaking and to return to its original form. Factors that affect the flexibility of a retentive clasp arm are its length, diameter, cross-section form, structure, and the alloy of which it is made.
clasp flexure,
clasp, formed,
n See clasp, wrought.
clasp, mesiodistal
n a type of clasp that embraces the distolingual and mesial surfaces of a tooth and takes its retention in either or both mesial and distal undercuts.
clasp, reciprocal, circumferential arm,
n an arm of a clasp located in such a manner as to reciprocate any force arising from an opposing clasp arm on the same tooth.
clasp, retentive circumferential arm (retention terminal),
n a circumferential clasp arm that is flexible and engages the infrabulge area at the terminal end of the arm.
clasp, Roach,
n See clasp, bar.
clasp, stabilizing circumferential arm,
n a circumferential clasp arm that is rigid and contacts the tooth at or occlusal to the surveyed height of contour.
clasp, stress-breaking action of,
n the relief for the abutment teeth from all or part of torquing occlusal forces; partially achieved by having a retentive arm of maximum flexibility that will provide adequate retention.
clasp, wrought (formed clasp),
n a clasp made of an alloy that has been drawn into various forms of wire.
