Abstract
The invention discloses a plate rod snap ring for a removable partial denture. According to the plate rod snap ring, the bottom of a U-shaped minor connector is connected with a connector; one end of the top of the U-shaped minor connector is connected with an occlusal rest on the mesial side of an oeclusal of an abutment, and the other end of the top of the U-shaped minor connector is connected with a distal adjacent panel; the distal adjacent panel is attached to a guide plane prepared from distal adjacent surfaces of the abutment; the cheek side upper end of the distal adjacent panel is connected with a retention arm; and the tail of the retention arm is clamped in an inverted concave area of the cheek side of the abutment and does not exceed a cheek axial ridge of the abutment. The plate rod snap ring for the removable partial denture does not influence the face and attractiveness of the patient, does not disturb the arrangement of artificial teeth and has a wide application range.
Description
Technical field
What the present invention relates to a kind of used for stomatological repair plucks (activity) denture clasp.
Technical background
Behind the absence of tooth, need to settle mouth mending material,, improve facial appearance to recover the chewing of patient, function of pronunciation.Mouth mending material commonly used can be divided into fixed restoration and activity prosthesis two big classes, and wherein removable partial denture is a big class of activity prosthesis, and it can repair various types of defect of dentition.Because indication is wide, moderate, it is of wide application general.
Removable partial denture is by the retainer of maintenance on abutment, repairs the artificial tooth of defect of dentition, fixing artificial tooth's base, connects the connector composition of base and retainer.The retainer of existing removable partial denture mainly is a snap ring, and snap ring is bent by metal casting or steel wire and forms, and its maintenance mode is: snap ring tip (end) extend into abutment fall recessed district and realize that the elasticity card embraces maintenance.Cast clasp can be divided into casting annular snap ring (A card) and casting bar clasp.The retention arm of casting annular snap ring (A card) and antagonism arm get into from interlock side abutment lip/buccal surface fall recessed district, hold three faces and four shaft angles of abutment, play maintenance and Stabilization; This kind snap ring also plays the support effect through the morsal occlusal lug of abutment simultaneously, and its fixation is good; But the physiological function that it is unfavorable for abutment, the row who influences food is overflow and to the physiological stimulation of gingiva; It is big to cover the abutment area, possibly cause the abutment dental caries bad; Can expose snap ring in the lip/cheek side of abutment simultaneously, influence attractive in appearance.The casting bar clasp gets into the recessed district of falling of abutment lip/buccal surface from abutment gum side, hold the lip/buccal surface of abutment; It and abutment contact area are less, and the position is hidden relatively, but owing to will get into down recessed district from abutment gum side, have to fall more greatly at soft tissue and can't use when recessed; Simultaneously, when being frist premolar, to attractive in appearance also influential as if abutment.Utilize the abutment proximal surface to fall the semicircle C type or the L type snap ring of recessed district maintenance; Though the lip/buccal surface at abutment can not expose snap ring; On performance attractive in appearance, make moderate progress, but semicircular arm of clasp is positioned at the abutment proximal surface, forms convexity at the abutment proximal surface; Can hinder adjacent artificial tooth's arrangement, and cause food impaction easily.
Summary of the invention
The object of the invention is exactly the deficiency to the snap ring existence of existing removable partial denture, provides a kind of removable partial denture to use the plate stem snap ring, and this snap ring does not influence patient's face, attractive in appearance; Simultaneously, do not hinder row's tooth of artificial tooth, applied widely.
The present invention realizes its goal of the invention; The technical scheme that is adopted is; A kind of removable partial denture is used the plate stem snap ring; Its composition is: the bottom of " U " type minor connector links to each other with major connector, during an end at " U " type minor connector top and basic dental masticatory surface are near the occlusal lug of side link to each other, the other end with far away in the proximal surface plate link to each other, far away in the proximal surface plate be fitted on the guiding plane that the far middle proximal surface by abutment is prepared into; The cheek side of proximal surface plate upper end links to each other with retention arm in far away, and what the end of retention arm was stuck in abutment cheek side falls recessed district and be no more than the cheek axle ridge of abutment.
Compared with prior art, the invention has the beneficial effects as follows:
One, the end of retention arm is stuck in the recessed district of falling of abutment cheek side, can well bring into play the maintenance effect; It can provide the maintenance power of 12～16N maintenance power test shows, can satisfy the requirement of clinical use fully.Its end is no more than the cheek axle ridge of abutment, and district's (near oral cavity front area) can't see snap ring in the buccal aspect (lateral surface) of abutment is near, does not influence patient's face well-done.
Two, middle proximal surface plate far away is fitted (closely contacting) with the guiding plane of abutment, can replace resisting the effect of arm performance good stable, and middle proximal surface plate far away simultaneously covers guiding plane fully, can not cause food impaction.In far away the proximal surface plate also to artificial tooth play guiding function with regard to potential energy, make things convenient for getting, wearing of artificial tooth.
Three, the proximal surface plate links to each other with connector through " U " type minor connector in far away, and the be connected length of retention arm with connector that extended has increased the elasticity of retention arm, also further facilitates winning and wearing of artificial tooth.The other end of " U " type minor connector links to each other with the mesial occlusion rest simultaneously, has strengthened the support and the Stabilization of artificial tooth.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed description.
Description of drawings
Fig. 1 is that the master that the embodiment of the invention is installed on the oral cavity model looks (the far away middle line of vision of abutment) structural representation.
Fig. 2 is that overlook (tooth of abutment closes the face direction) of Fig. 1 schemed.
Fig. 3 is side-looking (the cheek side direction of the abutment) figure of Fig. 1.
The net 7 at the scarce place of oral cavity model upper tooth is the saddle base that is used to connect the artificial tooth among Fig. 1-3.
The specific embodiment
Embodiment
Fig. 1-3 illustrates; A kind of specific embodiment of the present invention is; A kind of removable partial denture is used the plate stem snap ring; Its composition is: the bottom of " U " type minor connector 1 links to each other with major connector 2, an end at " U " type minor connector 1 top and the tooth of abutment 6 close face (occlusal surface) near in the occlusal lug 3 of side (near the oral cavity toe lateral) link to each other, the other end with far away in proximal surface plate 4 link to each other, far away in proximal surface plate 4 be fitted on the guiding plane that the far middle proximal surface (away from the forward face in oral cavity) by abutment 6 is prepared into; The cheek side (outside) of proximal surface plate 4 upper end links to each other with retention arm 5 in far away, and what the end of retention arm 5 was stuck in abutment cheek side falls recessed district and be no more than the cheek axle ridge of abutment 6.
" U " of the present invention type minor connector 1, major connector 2, occlusal lug 3, middle proximal surface plate 4 far away, retention arm 5 are not the individual member that is connected with each other, but the integral structure of one-time cast-forming.
