Problems solved by technology

[0005] However, in the current die-casting dental restoration casting process, there are no specific requirements for the above two specific requirements, and there are no related quality control guide tools to guide the casting and embedding of the restoration sprue, and often only rely on Embedding casting is performed based on the experience of the operator, which leads to a delay in improving the success rate of embedding casting of the restoration

Embodiment 1

[0033] A specific embodiment is a guide plate for oral cavity casting and embedding, including a main sliding rod 1, a horizontal rod 2, a slidable large nesting tube 3, a dial 4, a vertical rod 5, a slidable small nesting Tube 6.

[0034] The large nested pipe 3 is nested and installed on the main sliding rod 1 so that it can slide up and down on the main sliding rod 1; the horizontal rod 2 is used for horizontal maintenance, and the long axis of the horizontal rod 2 is marked with a scale. One end of 2 is fixedly connected with the large nested pipe 3, so that the horizontal bar 2 rotates on the horizontal plane around the long axis of the main sliding rod 1 through the large nested pipe 3. The main sliding bar 1 is kept vertical to the horizontal bar 2 . The other end of the horizontal bar 2 is also nested with a small nested tube 6, which can slide horizontally along the long axis of the horizontal bar; the small nested tube 6 is hinged with a vertical bar 5, and the vert...

Embodiment 2

[0039] A method for using a guide plate for oral cavity casting and embedding, comprising the following specific steps:

[0040]A. Press the guide plate piston 8 to start the electric resistance wire in the main sliding rod 1. After the temperature of the electric resistance wire rises, insert the nib 7 straight into the center of the main runner of the embedding ring base. The lowest point of the main sliding rod 1 is 0. The scale line is parallel to the base of the embedding ring. After the fixing is completed, the piston 8 is released, and the nib 7 can be fixed after it cools down.

[0041] B. Guide the casting process of the sprue: vertically and horizontally adjust the large nested tube 3 on the main sliding rod 1 to the scale 16mm on the main sliding rod 1, and then perform sprue casting:

[0042] B1. Select the length of the sprue according to the position determined by the horizontal bar 2, so that the total length of the sprue and the casting does not exceed the posi...

Abstract

The invention discloses a guide plate for oral cavity insert casting and embedding and a use method thereof, and relates to an oral medical instrument. The guide plate comprises a main slide rod, a horizontal rod, a sliding large nesting tube, a scale dial, a vertical rod and a sliding small nesting tube, wherein the large nesting tube is nested and installed on the main slide rod, and can be slide on the main slide rod up and down; one end of the horizontal rod is fixedly connected with the large nesting tube, so that the horizontal rod can be rotated around the long axis of the main slide rod on the horizontal surface through the large nesting tube; the small nesting tube is nested and installed at the other end of the horizontal rod, and can be slide along the long axis of the horizontal rod along the horizontal direction. The guide plate can well overcome the defects of lack of accurate and quantitative detection on the distance between a casting passage and a casting ring during insert casting and embedding in the embedding and casting process of the existing die-casting type casting. The guide plate for oral cavity insert casting and embedding has the advantages that the insert casting and embedding process can be precisely instructed and detected, the success rate in the embedding and casting process of a restoration body is improved, the purpose of quality control is realized, and the application prospect is broad.

Description

technical field [0001] The invention relates to oral medical instruments, in particular to a guide plate for oral cavity casting and embedding and a method for using the same. Background technique [0002] In the die-casting dental restoration casting process, there are standard requirements for the specific casting direction of the sprue on the restoration and the specific width and height of the casting ring when the restoration is embedded: [0003] Requirements for the sprue: the length of the sprue is 3-8mm, the vertical distance from the base of the investment ring to the top of the casting is no more than 16mm, the sprue is placed on the base of the investment ring, and the angle formed with the base is 45-60 degrees. [0004] Requirements for embedding: There must be at least a 10mm gap between the casting and the inner wall of the casting ring, and at least a 10mm gap from the top. [0005] However, in the current die-casting dental restoration casting process, the...
