Description

Wire ring gingival retraction assembly

Technical Field

The invention relates to the field of oral medical treatment, in particular to a wire ring gingival retraction device assembly.

Background

At present, after the tooth body of clinical mouth rehabilitation prepares, before taking the oral impression, the doctor must carry out the retraction to the tooth body after preparing, and the retraction apparatus commonly used clinically can't the fixed retraction gumline of precision, and the operation of retraction includes: a gingival retraction line with the width consistent with that of a gingival sulcus is selected and is pressed between an abutment and a free gingiva by a periodontal probe or a special gingival retraction device according to a clockwise or anticlockwise sequence, so that the gingiva moves towards the side and the tip of the gingiva and the gingival retraction line is adopted to retract the gingiva to reduce the clinical damage to periodontal tissues.

However, because the gingival retraction line is soft, the gingival retraction line is difficult to press into a tiny gingival sulcus in the gingival retraction process, the gingival retraction time is long in clinic, the gingival retraction line cannot be fixed, and the gingival retraction line is easy to fall out of the gingival sulcus. In addition, when the tooth body with the gum line is prepared, the gum line is often rolled out of the gingival sulcus by a high-speed mobile phone, and the gum of a patient is damaged.

Disclosure of Invention

According to the technical scheme provided by the invention, the wire ring gingival retraction device assembly comprises a gingival line fixing hoop, a gingival line fixing pipe and a gingival line fixing plate;

two ends of the gum line fixing hoop extend downwards to form fixing claws, and the fixing claws are folded inwards in an arc shape;

at least one side of the gum line fixing tube is provided with a gum line fixing clamp, and the gum line fixing tube can be fixed on the end face of the fixing claw.

Further, the gum line fixed plate includes the arc sheetmetal, the bottom of arc sheetmetal is equipped with the silica gel piece.

Further, the inner surface of the gum line fixing hoop is provided with a protective layer.

Further, the protective layer is a silica gel layer.

Further, be equipped with on the fixed pipe of gum line with the fixed pipe of gum line is upper tube as an organic whole even, the gum line fixation clamp sets up the both ends of upper tube.

Further, the length scope of upper tube 3~4mm, the length scope of the fixed pipe of gum line is 1~2 mm.

Furthermore, the end face of the fixed claw is provided with a clamping groove capable of clamping the upper pipe.

From the above, it can be seen that the wire ring gingival retraction assembly provided by the invention has the following advantages compared with the prior art: the invention has simple structure, compact design and convenient use, each part can be disinfected at high temperature to achieve the aim of thorough disinfection, the risk of unqualified hospital management is reduced, the convenience of clinical operation is kept, the gingival retraction cord is accurately fixed, the gingival retraction cord is not easy to fall off, the operation by a new hand is convenient in the process of clinical operation, the consumed time is short, and the gum is not easy to be damaged.

1. The gum line fixing device comprises a gum line fixing hoop, 2 a gum line fixing tube, 3 a gum line fixing plate, 310 an arc-shaped metal sheet, 320 a silica gel sheet, 4 a gum line fixing clamp, 510 a fixing claw, 6 a clamping groove and 7 an upper tube.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings. The terms "inner" and "outer" are used to refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1 to 5, a wire ring gingival retraction device assembly comprises a gingival line fixing hoop 1, a gingival line fixing tube 2 and a gingival line fixing plate 3;

at least one side of the gum line fixing tube 2 is provided with a gum line fixing clip 4, and the gum line passes through the gum line fixing tube 2 and then is fixed at one end of the gum line fixing clip 4, so that even if multi-layer gum retraction is required, the gum line can be reliably fixed by the gum line fixing tube 2;

two ends of the gum line fixing hoop 1 extend downwards to form fixing claws 510, each fixing claw 510 is in arc-shaped inward contraction, a clamping groove 6 capable of clamping the upper pipe 7 is formed in the end face of each fixing claw 510, and the clamping grooves 6 enable the gum line fixing pipe 2 to be fixed on the end face of each fixing claw 510; the fixed hoop 1 of gum line can staple bolt the tooth side, and the stationary dog 510 can be pressed the fixed pipe 2 of gum line into the gum to fixed gum line. Compare with the stationary dog 510 of straight shape, its terminal surface can expand the gingival sulcus when the fixed hoop 1 of gum line of arc adduction is cliied the tooth, thereby in pressing into the gingival sulcus with the fixed pipe of gum line and gum line, make the gum line fixed more reliable, avoid the gum line to fall out outside the gingival sulcus, and the gum line of reliably fixing can let the tooth body prepare under the gum neck shoulder of in-process more smooth, do not have sharp rough edge, the clear delivery of being convenient for.

Gum line fixed plate 3 includes arc sheetmetal 310, the bottom of arc sheetmetal 310 is equipped with silica gel piece 320, and gum line fixed plate 3 is arranged in the slit between the tooth to silica gel piece 320 pushes down the gum line, and arc sheetmetal 310 cramps the tooth, prevents that the gum line from sliding on.

The inner surface of the gum line fixing hoop 1 is provided with a protective layer, the protective layer can prevent the gum line fixing hoop 1 from scratching teeth when being fixed on the teeth, and the protective layer is a silica gel layer.

Be equipped with on the fixed pipe 2 of gum line with the fixed pipe 2 of gum line is upper tube 7 as an organic whole even, gum line fixation clamp 4 sets up the both ends of upper tube 7.

3~4mm of length scope of upper tube 7, the length scope of the fixed pipe 2 of gum line is 1~2mm, and the length of upper tube 7 is a little longer than the length of the fixed pipe 2 of gum line can be convenient for pass the gum line in the fixed pipe 2 of gum line and fix on the gum line fixation clamp 4 of upper tube 7.

The working principle and the using process of the invention are as follows:

wind the gum line around the tooth root on the gum, pass a gum line fixed tube 2 respectively with the both ends of gum line, and fix the end of gum line on gum line fixation clamp 4, with the fixed hoop 1 hoop of gum line at the tooth global, upper tube 7 is pushed down to stationary dog 510, thereby fixed gum line, 3 stoppers of gum line fixed plate are in the slit between the tooth at last, push down the gum line with silicon film 320, thereby firmly push down the gum line and avoid damaging the gum.

Those of ordinary skill in the art will understand that: the above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents, improvements and the like made within the spirit of the present invention should be included in the scope of the present invention.
