Description

  The present invention relates to a dental impression collection tray that is particularly suitable for use in collecting human upper jaw teeth and gums.

  Conventionally, a dental impression collecting tray for collecting a maxillary tooth mold or gum mold for making a human mouthpiece or denture is made of a synthetic resin as shown in FIGS. The tray body 10 has a raised portion 11 at a position facing the palate at the center, and the height of the raised portion 11 and the height of the outer wall 12 are the same.

  Therefore, when the dental impression is collected, the raised portion 11 or the impression material hits the portion of the patient's palate, and the impression material overflows and is pushed toward the back of the mouth. In addition to causing an unpleasant mood, there is a problem that it is difficult to collect an accurate impression because the subject moves from an unpleasant mood. In addition, since the impression material may spread over the palate when taking an impression of a tooth mold, it may be difficult to trim the palate with gypsum after taking the impression.

  Furthermore, if the height of the raised portion and the height of the outer wall portion are the same, the upper jaw portion is actually higher on the outer side than the inner side of the dentition, so that there is a problem in that the impression material is leaked from the outer side during impression collection. Above, the shape of the upper jaw of the sampled person, the gum type and the shape of the tooth mold are various. Conventionally known ones are made of synthetic resin and cannot be deformed, so there are many types with different shapes and sizes. There is also a problem that it is difficult to take an accurate tooth shape without preparing the tooth. Furthermore, this kind of dental impression collection tray requires a certain degree of rigidity in view of its intended purpose, but conventionally known ones tend to lack this rigidity.

  This device is intended to solve the above-mentioned problems of the prior art, and its purpose is to prevent the patient from feeling uncomfortable when collecting the dental mold and to accurately determine the dental mold. Provide a tray for collecting dental impressions, especially for upper eyelids, which can be easily taken, and can be easily trimmed afterwards, and can be used with a variety of subjects with various types of teeth and gums. There is.

  In order to achieve the above object, the device according to claim 1 comprises a tray main body and a handle portion attached to the tray main body, the tray main body is constituted by a wire mesh, the handle portion is constituted by a wire, and The tray body has a substantially horseshoe shape in which the portion that touches the palate is removed, and the substantially horseshoe-shaped part of the plane is configured to have a substantially U-shape, and the edge portion is covered with an edging member. Is characterized in that the outer wall part on the lip side and the cheek side part is made higher than the inner wall part on the palate side.

  The invention of claim 2 is characterized in that the handle portion is composed of a gripping portion and a flat substantially horseshoe-shaped mounting portion formed continuously at one end of the gripping portion. It is fixed to the bottom.

  According to a third aspect of the present invention, the gripping portion further includes an outer gripping portion obtained by bending the wire into a substantially U-shaped plane, and an inner gripping portion provided in the longitudinal direction of the central portion of the outer gripping portion. The mounting portion is composed of a planar substantially horseshoe-shaped outer mounting portion provided following the outer gripping portion, and a pair of inner mounting portions formed by bending from each end of the outer mounting portion. The one of the inner mounting portions is connected to the inner gripping portion, and the other of the inner mounting portions is fixed to the tray body.

  As described above, according to the present invention, the impression material or the raised portion does not press the palate of the subject when the impression is taken of the tooth shape or the gum type, and the subject's feeling does not get worse. As a result, there is no movement when the subject feels bad, so accurate impressions can be collected. Furthermore, by making the height of the outer wall higher than the height of the inner wall in the impression collection tray, the leakage of the impression material is reduced and more accurate impression collection can be performed. And since the impression collection tray according to the present invention is made of wire mesh, it is hygienic and can be used repeatedly. By modifying as necessary, impression collection trays that fit more various patient's gum rows can be obtained. We were able to provide it.

  Embodiments will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of a dental impression collecting tray according to the present invention, FIG. 2 is a bottom view thereof, FIG. 3 is a side view thereof, FIG. 4 is a rear view thereof, and FIG.

  In the drawing, the reference symbol 1 is a tray body, and the tray body 1 is composed of, for example, a stainless steel wire mesh 1a and an edge member 1b. The mesh of the wire mesh is not particularly limited as long as the impression material does not leak out. In addition, when the impression material is put inside and pressed against the dentition for mold making, it is only necessary to have rigidity and strength that does not bend and do not easily deform without bending. As shown in FIGS. 1 and 5, the tray main body 1 has a substantially horseshoe shape in which a portion corresponding to the palate is deleted and matched to the shape of the gum row, and in particular, as shown in FIG. The substantially horseshoe-shaped part has a substantially U-shaped stem shape, and its edge is edged by the edge member 1b. In particular, as shown in FIG. 4, in the tray body 1, the height A of the outer wall 2b located on the palate side and the cheek side is higher than the height B of the inner wall 2a on the inner side. It is comprised so that it may become. The tray body 1 has several sizes, large, medium and small, and is not limited to the illustrated one.

  Next, the one with the instruction symbol 3 is a handle portion, and this handle portion 3 is configured using, for example, a stainless steel wire (the diameter of the embodiment is 2.5 mm to 3 mm). And an attachment portion 5. The thickness of the wire is φ2 in the drawing. The thickness of the wire is preferably about this, but it is sufficient that the wire does not bend or deform when the impression material is put into the tray body and pressed against the dentition to make a mold. The gripping part 4 is composed of an outer gripping part 4a having a substantially U-shaped plane and an inner gripping part 4b provided in the longitudinal direction of the central part of the outer gripping part 4a, and the mounting part 5 is a gripping part. A pair of outer mounting portions 5a, 5a, which are formed integrally with the outer gripping portion 4a, and have a substantially horseshoe shape, and an inner side which is folded inward from the ends of the outer mounting portions 5a, 5a. It is comprised from the attaching parts 5b and 5b.

  The attachment portion 5 is fixed to the outer bottom portion of the tray body 1 as a whole by means such as welding, and one of the inner attachment portions 5b and 5b is integrated with the inner gripping portion 4b, and the other is the tray. The main body 1 is bent and fixed to the rear end side. In addition, the fixing means to the tray main body 1 of the attachment part 5 is not limited to welding, It can be based on well-known means, such as screwing and caulking. And the thing of the instruction symbol 6 is the connection fixing member of the outer side grip parts 4a and 4a of the grip part 4 and the inner side grip part 4b.

  Therefore, put impression materials (alginate (alginate) powdered into a bowl shape, molybdenum compound, silicon rubber, etc.) into the tray body 1 of the dental impression collection tray according to this device and hold it with one hand. Hold the part 4 and put the tray body 1 in the mouth of the person to be collected, press it against the gum row of the upper jaw and hold it for 4 to 5 minutes, then wait for the impression material to harden and take the teeth and gums However, since the tray body 1 has a portion that contacts the palate, the raised portion or impression material hits the palate or the impression material is pushed toward the back of the mouth, as is conventionally known. Does not irritate the mouth or throat. Therefore, it is possible to accurately collect impressions without causing the subject to feel vomiting that makes the patient feel unwell. And since the outer wall of the tray main body 1 is made higher than the inner wall, it is possible to prevent the impression material from leaking out as much as possible, and it is easy to perform trimming at the time of mold making with plaster. In addition, since the tray body 1 is made of a wire mesh and can be deformed by using hands or pliers, the single tray body 1 can cope with subjects having different gum shapes and teeth shapes and sizes. It has become.

  Furthermore, since both the tray body 1 and the handle 3 are made of metal, they have an appropriate rigidity and have an accurate tooth shape and the like without being deformed during the holding time of 4 to 5 minutes at the time of impression collection. Since the tray body 1 is a wire mesh, the impression material enters the mesh and hardens. Therefore, when removing the impression material from the tooth portion, the tray body 1 can be removed together with the tray body 1. This prevents only the impression material from remaining on the teeth.

  Furthermore, since a rigid metal is used for the tray body 1 and the handle 3, it can be used repeatedly without being deformed or sagging, and sterilized in hot water or alcohol. Therefore, it can be used safely and hygienically even after repeated use. The tray body 1, the handle 3 and the edge member are preferably made of stainless steel, but are not limited to this, and all or part of the tray body should be made of copper and the surface thereof should be chrome plated. Can do. Thus, when it is made from copper, there exists an advantage that it is easy to process.

  And, the dental impression collecting tray according to this device can be used as it is when taking an impression of the lower jaw side tooth type and gum type, and since the portion where the tongue hits is deleted at the time of dental impression collecting, It is possible to accurately collect impressions of teeth and gums without being moved by the tongue.
