Guide plate for oral cavity insert casting and embedding and use method thereof

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...

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
