る。<Conventional technology> Generally, there are two types of dentures: polar dentures and complete dentures.
The manufacturing of these dentures involves impression-taking, plaster injection,
The process involves creating a wax, arranging the artificial teeth, implanting a flask, melting the wax, filling the flask with resin, heating polymerization, and removing the denture mold. Anhydrite, anhydrite and dental plaster are used in the plastering process. Traditionally, instruments such as forceps have been used to remove a denture from a hardened plaster tooth mold, and the denture must be carefully broken using the human grip from the edges without damaging it. This poses a problem in that it requires a certain degree of skill and requires a great deal of labor and time. If the denture is deformed, it becomes difficult to fix the denture at the time of insertion, making it difficult to use, and the reality is that only a few dentures can be removed from the mold each day.

More than one species has been selected.
〈実施例〉
以下、実施例とともに、本発明に係る義歯用石
膏破壊剤について説明する。<Example> Hereinafter, the denture plaster destroying agent according to the present invention will be described along with Examples.
本発明において義歯用歯型より義歯を取り出す

数に特別の限定を設ける必要はなく、脱型時間、
石膏歯型の大きさ等により適宜選択される。 In the present invention, when removing a denture from a denture tooth mold, a predetermined position of the plaster tooth mold, for example, 2 to 10 mm, preferably 3 to 5 mm, into the plaster tooth mold near the denture.
The process begins by drilling holes using a drilling machine such as a small electric drill. The length of the hole should be such that it does not penetrate the plaster tooth mold, and even if the hole does penetrate the plaster tooth mold during drilling, it should be held down with tape or the bottom with plaster, etc. to prevent the expansion material from flowing out from the bottom. Just leave it there. It should be noted that there is no need to set any special limitations on the position and number of holes to be drilled, and the demolding time,
It is selected appropriately depending on the size of the plaster tooth mold.

張材の粉末または顆粒を孔中に充填した後に水を
注入してもよい。 When the drilling is completed, the drilling is filled with an intumescent material. The denture plaster breaking material used in the present invention is one that develops expansion pressure upon hydration reaction with water, such as "Blystar" (manufactured by Onoda Cement Co., Ltd.) (trade name) and other known static plasters. In addition to the crushing agent, one or more of cement concrete expansion agents, quicklime, calcined dolomite, etc. can be used, and if necessary, sodium silicofluoride,
A hydration reaction inhibitor such as citric acid or tartaric acid may also be mixed therein. Also, when filling,
A slurry prepared by mixing the expanding material with water may be filled into the holes using a syringe or a dropper, or water may be injected after filling the holes with powder or granules of the expanding material.
膨張材を孔中に充填すると膨張材は孔中で十分
に養生され、膨張材の膨張によつて生ずる膨張圧
が石膏歯型に伝わり、石膏歯型が破壊されるもの
である。 When the expanding material is filled into the hole, the expanding material is sufficiently cured in the hole, and the expansion pressure generated by the expansion of the expanding material is transmitted to the plaster tooth mold, thereby destroying the plaster tooth mold.
なお、破壊時間を短縮するためには、膨張材を
孔中に充填した後に30゜〜80℃の温水（冷水に浸
漬した後に加温してもよい。）やスチームバスに
浸漬すると効果的であり、１時間以内の破壊が可
能となる。 In addition, in order to shorten the destruction time, it is effective to immerse the material in warm water at 30° to 80°C (you may warm it up after immersing it in cold water) or in a steam bath after filling the hole with the expanding material. Yes, it can be destroyed within one hour.

できた。Example 1 A hole with a hole diameter of 5 mm was made using an electric drill to adjust the hole length on the peripheral interface between the complete denture and the plaster tooth-shaped complete denture.
A hole of 10 to 12 mm was drilled, and the hole was filled with a slurry of an expanding material "Blystar" (manufactured by Onoda Cement Co., Ltd.) (trade name) mixed at a water ratio of 30% using a dropper. After that, cover the entire surface of the plaster tooth mold with a cloth and heat it at 40°C.
When soaked in hot water, cracks appeared between the perforations within 40 minutes, and the denture was easily removed from the plaster tooth mold.

ことができた。Example 2 A hole with a hole diameter of 3 mm and a hole length of 10 mm was drilled in the peripheral interface between the polar denture and the plaster tooth-shaped polar denture using an electric drill. Filled with blister powder for fast winter use. When this was left in warm water at a room temperature of 30℃,
A crack appeared within 10 minutes, and after 20 minutes, the crack had expanded to the area between the perforations, allowing the denture to be easily removed from the plaster tooth mold.
以上、実施例とともに説明したように、本発明
に係る義歯用石膏破壊剤によれば、
１ 破壊に際して熟練を要せず容易に脱型するこ
とができる。 As described above in conjunction with the Examples, according to the denture plaster destroying agent according to the present invention: 1. It is possible to easily remove the mold without requiring any skill at the time of destruction.
２ 従来の鉗子等による破壊においては義歯に対

る。2. In conventional destruction using forceps, etc., local (concentrated) stress was generated on the denture, which had an adverse effect on the denture, but by using an expanding material, the expansion pressure developed was balanced, and no uneven stress was generated. ,
The effect on dentures can be kept to a minimum.
