Abstract
The elastically tensioned dental matrix wedge is a dental matrix wedge for use in dental restoration procedures. The elastically tensioned dental matrix wedge includes a hollow elongated body having first and second longitudinally opposed ends. The first end is at least partially open and the second end is closed. An elongated tube is mounted within the hollow elongated body and extends longitudinally therein. A spiral torsion spring is secured to, and wraps about, the elongated tube. A clip is provided for releasably holding the spiral torsion spring in a compressed state. Release of the clip allows the spiral torsion spring to expand and exert an elastic tension force on an inner surface of the hollow elongated body.
Claims6
An elastically tensioned dental matrix wedge, comprising:
- a hollow elongated body having first and second longitudinally opposed ends, the first end thereof being at least partially open and the second end being closed;
- an elongated tube mounted within the hollow elongated body and extending longitudinally therein;
- a spiral torsion spring secured to, and wrapped about, the elongated tube;
- and
- a clip for releasably holding the spiral torsion spring in a compressed state, wherein release of the clip allows the spiral torsion spring to expand and exert an elastic tension force on an inner surface of the hollow elongated body, wherein the elastically tensioned dental matrix wedge is configured to be inserted into an interproximal space between a dental matrix band and a tooth, and secured therebetween by action of the elastic tension force.
A method of securing a dental matrix, comprising the steps of:
- positioning a dental matrix band between a tooth to be restored and an adjacent tooth;
- inserting at least a portion of an elastically tensioned dental matrix wedge between the dental matrix band and the adjacent tooth, below a cavity gingival margin thereof, the elastically tensioned dental matrix wedge having a spiral torsion spring mounted within a hollow elongated body of the elastically tensioned dental matrix wedge, the spiral torsion spring being releasably held in a compressed state within the hollow elongated body by a clip;
- and
- releasing the clip such that the spiral torsion spring expands to exert an elastic tension force on an inner surface of the hollow elongated body.
