２内に埋設して同時に固定する。 Reference numeral 1 denotes an outer stand-side flask, which is made of cast metal such as aluminum or brass, and has a square dish shape. A jaw plaster base 3 in the shape of the patient's jaw is attached and fixed to the interior of the base side flask 1 via a soft kneaded plaster 2. A jaw model 4 made of wax is attached to the upper part of the jaw plaster stand 3, and a desired number of synthetic resin or ceramic dentures 5 are arranged and fixed on the upper surface of the jaw model 4.
The jaw model 4 and denture teeth 5 are usually called wax dentures.
One end of each of a supply rod 6 and a discharge rod 7 is fixed to one side of the wax denture. Both the supply rod 6 and the discharge rod 7 are made of bent wax, which is a material that melts with heat, similar to the jaw model 4.
One end of the supply rod 6 is fixed to the jaw model 4, and the other end is provided facing outside from one side 9 of the base flask 1. 8 is a supply port. The discharge rod 7 is attached to the jaw model 4 in parallel with the supply rod 6, and detours the inside of the stand-side flask 1 toward the other side 10, with its terminal end 11 directed outward from the other side 10. Make it stand out. When the discharge rod 7 is fixed with the plaster 2, a part of the discharge rod 7 is buried in the plaster 2 and fixed at the same time.
次に別に軟かく溶いた石膏泥１２を作り、ヘラ
とか刷毛１３で蝋義歯に塗付ける。このとき、義
歯牙５と義歯牙５の隙間、顎模型４と義歯牙５の
隙間に特に注意して塗付け、隙間を完全に埋めて
おく。このことは、本発明の大切な行程の一つで
ある。 Next, make a separate soft dissolved plaster mud 12 and apply it to the wax denture using a spatula or brush 13. At this time, pay particular attention to the gaps between the denture teeth 5 and the gaps between the jaw model 4 and the denture teeth 5, and completely fill the gaps. This is one of the important steps of the present invention.
すると、第３図、第４図のように、表面は石膏
泥１２で覆われた蝋義歯ができる。 Then, as shown in FIGS. 3 and 4, a wax denture whose surface is covered with gypsum mud 12 is formed.
次にフラスコの蓋１４を被せ、台側フラスコ１
と蓋フラスコ１４を外側から固定具１５で挟んで
完全に固定し、これを第４図のように立てる。そ
して、容器１６内に石膏を溶いて作つた石膏液１
７を供給口８より流し入れると、台側フラスコ
１、蓋１４内の空間１８は石膏液１７で一杯にな
る。この状態でフラスコ１，１４を外側から加温
し、前記顎模型４と供給用棒体６と排出用棒体７
を暖めて、これらをゆるくする。 Next, cover the flask with the lid 14, and place the flask 1 on the stand side.
The lid flask 14 is completely fixed by sandwiching it between the fixtures 15 from the outside, and it is erected as shown in FIG. Then, a gypsum solution 1 made by dissolving gypsum in a container 16
When 7 is poured from the supply port 8, the space 18 in the stand-side flask 1 and the lid 14 is filled with the gypsum solution 17. In this state, the flasks 1 and 14 are heated from the outside, and the jaw model 4, supply rod 6, and discharge rod 7 are heated.
Warm them up and loosen them.
その後供給用棒体６の部分より水と蒸気とを交
互に供給して洗浄すると、蝋材の顎模型４と供給
用棒体６と排出用棒体７との部分は溶けて無くな
るので、顎模型４に取付けられていた義歯牙５
は、固まつた石膏液１７に固定されることにな
り、顎模型４と供給用棒体６と排出用棒体７との
部分は空洞となる。 After that, water and steam are alternately supplied from the supply rod 6 for cleaning, and the wax jaw model 4, supply rod 6, and discharge rod 7 melt and disappear. Denture teeth 5 attached to model 4
is fixed in the hardened plaster solution 17, and the portions of the jaw model 4, supply rod 6, and discharge rod 7 become hollow.
そこで、供給用棒体６の跡の上部に案内筒１９
を立て、案内筒１９内にレジン樹脂液を流入し、
シリンダー１８のピストン２０によりレジン樹脂
を圧入する。するとレジン樹脂は油圧シリンダー
１８により隅々まで一気に休むことなく圧入され
る。 Therefore, a guide cylinder 19 is placed above the remains of the supply rod 6.
, and let the resin liquid flow into the guide tube 19.
The resin is press-fitted by the piston 20 of the cylinder 18. Then, the resin is press-fitted into every corner at once by the hydraulic cylinder 18 without stopping.
なお、レジン樹脂と義歯牙５との結合を完全に
するため、次いで、加熱することがあり、加熱す
るとレジン樹脂と義歯牙５とは完全に重合する。 In order to completely bond the resin resin and the denture tooth 5, heating may be performed next, and when heated, the resin resin and the denture tooth 5 completely polymerize.
すでに述べたように、従来の入歯は、義歯牙と
義歯牙の間隙、義歯牙とレジン義歯台との間隙等
の入りくんだ部分が、美麗に出来ない欠陥があつ
た。そこで従来は、装置全体に振動を与えたりし
ていたが、振動を与えた位ではとても細かい隙間
に石膏とかレジンが入らないので欠陥克服の解決
とはならないばかりでなく、振動などを与える
と、細部の石膏が欠けたりして、むしろ、別の欠
陥が生じた。 As already mentioned, conventional dentures have a defect in that the intrusive parts, such as the gap between the dentures and the gap between the dentures and the resin denture base, cannot be made beautifully. Conventionally, vibrations were applied to the entire device, but applying vibrations does not allow plaster or resin to enter the very small gaps, so it is not a solution to overcoming defects. Rather, other defects occurred, such as missing plaster details.

歯が出来る効果がある。 The present invention involves inserting and fixing a jaw plaster base 3 having a mold of the patient's jaw into the base side flask 1, attaching a jaw model 4 made of wax material to the jaw plaster base 3, and fixing the jaw model 4 made of wax material. A synthetic resin or ceramic denture 5 is fixed to the denture 4, and a soft melted gypsum mud 12 is made separately, and a spatula or brush 13 is used to clean the gap between the denture 5 and the jaw model 4 and the denture 5. Apply it to the gap, and fix one end of each of the supply rod 6 and the discharge rod 7 made of wax material to one side of the jaw model 4, and the supply rod 6 is attached to one side of the stand-side flask 1. The discharge rod 7 bypasses the inside of the flask 1 on the stand side, and then its terminal end 11 is made to protrude outside from the other side 10 of the flask 1 on the stand side, and a lid is attached to the flask 1 on the stand side. The side flask 14 is placed, the flasks 1 and 14 are placed with the other side 10 facing down, and the space 18 in the flasks 1 and 14 is filled with plaster solution 17, and the jaw model 4 is heated and washed.
Then, the supply rod 6 and the discharge rod 7 are removed, and the resin is press-fitted from the place where the supply rod 6 is removed, and the denture is manufactured by press-fitting the resin before the gypsum liquid 17 is flowed into the space 18 and filled. Separately, I made a soft melted plaster mud 12 and applied it to the gaps between the denture teeth 5 and the gaps between the jaw model 4 and the denture teeth 5 using a spatula or brush 13, so that I could make a mold for the difficult areas. This can be done completely, and the discharge rod 7 bypasses the inside of the stand-side flask 1 and then has its terminal end 11 protrude outside from the other side 10 of the stand-side flask 1.
The press-fitting resistance of the resin is increased, and the resin is press-fitted neatly into every corner, resulting in the creation of highly accurate and beautiful dentures.
