（従来の技術）
一般に歯科治療で、上顎の総義歯を製作する場
合、印象材を盛つた印象用トレーを口腔内に挿入
して、上顎に印象材を押し付けて、その形状を写
し取ることが行われている。(Prior art) Generally, when manufacturing a complete denture for the upper jaw in dental treatment, an impression tray filled with impression material is inserted into the oral cavity, the impression material is pressed against the upper jaw, and the shape is copied. It is being said.

合、例えば寒天とアルギン酸の印象材６を盛り、
これを口腔内に挿入して、上顎に押し当てて、印
象を採得する。 In the conventional maxillary impression tray, for example, as shown in FIGS. 3 and 4, a perforated metal plate 1 is bent, and a side plate 3 is erected on the curved periphery of a bottom plate 2 which has a half-elliptical shape when viewed from above. The bottom plate 2 of the tray body 4 provided
It has a shape in which a grip part 5 is joined to the front edge of the handle. When taking an impression of the upper jaw using the above-mentioned tray, for example, the impression material 6 of agar and alginic acid is placed,
This is inserted into the oral cavity and pressed against the upper jaw to take an impression.
このとき印象材６は流動性があるので、印象材
６が印象用トレーの側板３のない後縁側から流れ
出して、患者の喉に流入し、息苦しくなつたり、
嘔吐することが度々あつた。 At this time, since the impression material 6 is fluid, the impression material 6 flows out from the rear edge side of the impression tray where the side plate 3 is not provided and flows into the patient's throat, causing difficulty in breathing.
I often had vomiting.
また、このように後縁側の印象材６が流れる
と、上顎結節部が正確に印象採得できず、義歯の
安定性が悪くなるなどの欠点があつた。 In addition, when the impression material 6 on the posterior edge side flows in this way, it is impossible to accurately take an impression of the tuberosity of the maxilla, resulting in disadvantages such as deterioration of the stability of the denture.
（考案が解決しようとする問題点）
本考案は、かかる点に鑑みなされたもので、印
象を採得するとき、印象材が喉に流れるのを防止
すると共に、正確な印象を採得して義歯の安定性
が得られる上顎印象用トレーを提供するものであ
る。(Problems to be solved by the invention) The present invention has been devised in view of the above-mentioned points, and is designed to prevent the impression material from flowing down the throat when taking an impression, and also to prevent the impression material from flowing into the throat when taking an impression, and to make it possible to take an accurate impression and improve the quality of the denture. The present invention provides a maxillary impression tray that provides stability.

部を設けたことを特徴とするものである。(Means for Solving the Problems) The present invention provides a tray main body in which a side plate is provided upright on a curved peripheral edge of a bottom plate having a planar half-elliptical shape, from the side plate along the rear edge of the bottom plate. It is characterized by the provision of a weir section with a low height.

ことができる。(Function) In the maxillary impression tray of the present invention, when the tray body is filled with impression material, inserted into the oral cavity, and pressed against the upper jaw, the dam acts as a dam to prevent fluid impression material from flowing out. In addition to preventing the impression material from flowing into the patient's throat, the top surface of the raised impression material is almost constant, and the dam is formed lower than the side plate, allowing accurate impressions to be taken along the curved upper jaw. be able to.
（実施例）
以下本考案の一実施例を第１図および第２図を
参照して詳細に説明する。(Embodiment) An embodiment of the present invention will be described in detail below with reference to FIGS. 1 and 2.
多孔金属板１をプレス成型して、平面半割楕円
状をなす底板２の湾曲した周縁部に沿つて側板３
を立設してトレー本体４が形成されている。 A side plate 3 is formed by press-molding a porous metal plate 1 to form a side plate 3 along the curved peripheral edge of a bottom plate 2 which has a half-elliptical shape when viewed from above.
The tray body 4 is formed by standing upright.
底板２は、上顎の形に沿つて、中央部が後縁側
に向つて上方に張り出している。 The center portion of the bottom plate 2 protrudes upward toward the rear edge along the shape of the upper jaw.
また側板３は、第２図に示すように、その上縁
内側に断面円形状の突条部７が形成されている。 Further, as shown in FIG. 2, the side plate 3 has a protrusion 7 having a circular cross section formed on the inner side of its upper edge.
更に底板２の側板３を設けていない後縁部に沿
つて堰部８が設けられ、この上縁内側にも断面円
形状の突条部７が形成されている。 Further, a weir portion 8 is provided along the rear edge of the bottom plate 2 where the side plate 3 is not provided, and a protrusion portion 7 having a circular cross section is also formed inside this upper edge.
この堰部８の高さは側板３の高さの10〜30％程
度に形成され、10％未満では印象材６を確実に保
持できず、また30％を越えると上顎に当る虞れが
あるので上記範囲が好ましい。 The height of this weir part 8 is formed to be about 10 to 30% of the height of the side plate 3. If it is less than 10%, the impression material 6 cannot be held securely, and if it exceeds 30%, there is a risk that it will hit the upper jaw. Therefore, the above range is preferable.
なお、多孔金属板１としては、パンチングメタ
ルの他、金網でも良く、またキヤステイングによ
りトレーを一体に成型したものでも良い。 In addition to punching metal, the porous metal plate 1 may be a wire mesh, or may be formed by integrally molding a tray by casting.
従つて、上記構成の印象用トレーでは、トレ本
体４に印象材６を盛り上げて患者の口腔内に挿入
し、上顎に押し付けても、後縁側に堰部８がある
ので、ダム作用によりここから喉側への流出が防
止される。また印象材６が流出しないので、上顎
結節部を正確に印象採得することもできる。 Therefore, in the impression tray configured as described above, even if the impression material 6 is heaped up on the tray body 4 and inserted into the patient's oral cavity and pressed against the upper jaw, since the dam part 8 is on the rear edge side, the impression material 6 will not be removed from there due to the dam action. This prevents it from flowing into the throat. Furthermore, since the impression material 6 does not flow out, it is possible to accurately take an impression of the maxillary tuberosity.
また側板３と堰部８の上縁内側には、断面円形
状の突条部７が形成されているので、印象材６が
更に確実に保持されるようになつている。 In addition, since a protrusion 7 having a circular cross section is formed on the inner side of the upper edge of the side plate 3 and the weir part 8, the impression material 6 is held more reliably.

The stability of the denture can be achieved by obtaining this.
