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.
Description
Technical field
The present invention relates to dental device, relate in particular to a kind of Oral Repair extracoronal retention snap ring.
Background technology
Defect of dentition patient is because self dissect physiology condition is limit or when other reasons can not adopt fixed and repaired treatment, available removable partial denture carries out the reparation of missing tooth.Removable partial denture is simple for production, and indication is wide, cheap.Removable partial denture is being made when using, and not only needs to consider to recover the form of missing tooth, chews and the function such as pronunciation, also will consider to recover and improve the attractive in appearance of face simultaneously.
The composition of removable partial denture is: the artificial tooth at anodontia place is arranged on saddle base, and saddle base is connected with snap ring by major connector; Snap ring is as extracoronal retention device, and that can pluck is arranged on abutment, can to artificial tooth, carry out maintenance and stable preferably, guarantees the normal functionating of artificial tooth.But existing snap ring, the retention arm of its cheek side (outside of tooth) easily appears metal color, diminishes aesthetic property, to patient is social, waits daily routines to impact.
Summary of the invention
Object of the present invention is just to provide a kind of combined short arm clasp for removable partial denture, this kind of associating galianconism snap ring do not damaging under the prerequisite of denture retention, support and Stabilization, can reduce and eliminate the exposure of cheek side arm of clasp metal part, improve artificial tooth aesthetic property.
The technical solution adopted for the present invention to solve the technical problems is that a kind of combined short arm clasp for removable partial denture, is arranged on two adjacent abutments, it is characterized in that: by two cheek arm of clasp, body of clasp,
rest, minor connector, tongue side antagonist are connected to form successively, and two cheek arm of clasp are connected with body of clasp and are " people " font; And in gum side's embrasures of the elasticity position of two described cheek arm of clasp between two abutments, its tip is no more than the cheek axle ridge of abutment.
Compared with prior art, the invention has the beneficial effects as follows:
One, retention derives from the embrasures of the gum side's (gingiva direction) between adjacent two abutments, is applicable to one-sided agomphosis, gapped person between short and firm or adjacent two teeth of abutment corona; Its retention is from two abutment Dao Ao districts, and retention effect is good, can guarantee maintenance, support and the Stabilization of artificial tooth.
Two, the tip of two cheek arm of clasp of the present invention is no more than the cheek axle ridge of abutment, and good concealment, obviously reduces the exposure of cheek side metal, and aesthetic property is good.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is that snap ring of the present invention is arranged on the plan structure schematic diagram in the oral cavity model of anodontia.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
In Fig. 1,2,8 is the major connector of Joining clasp and saddle base 7, on saddle base 7, artificial tooth is installed.
The specific embodiment
Embodiment
Fig. 1-2 illustrates, and a kind of specific embodiment of the present invention is that a kind of combined short arm clasp for removable partial denture, is arranged on two adjacent abutments 6, it is characterized in that: by two cheek arm of clasp 1, body of clasp 2,
rest 3, minor connector 4, tongue side antagonist 5 are connected to form successively, and two cheek arm of clasp 1 are connected with body of clasp 2 and are " people " font; And in gum side's embrasures of the elasticity position of two described cheek arm of clasp 1 between two abutments 6, its tip is no more than the cheek axle ridge of abutment 6.
Tongue side antagonist 5 of the present invention can be the tongue side antagonism arm of clasp in Fig. 1-2, also can be the holder of tongue side group.
Cheek arm of clasp 1 in the present invention, body of clasp 2,
the individual member that rest 3, minor connector 4, tongue side antagonist 5 and major connector 8, saddle base 7 are not connected with each other; But the integral structure of one-time cast-forming.
