METHOD AND DEVICE FOR PRODUCING DENTAL PROSTHESES Russian patent published in 2008 - IPC A61C13/20 

FIELD: medicine; medical engineering.

SUBSTANCE: device has base bearing step frame. One of steps is parallelepiped-shaped and the other one is cylinder-shaped. Temperature sensor is set on cylinder surface. Heating element is mounted on cylinder perimeter. Heating chamber is mounted inside of the frame. The heating chamber has cartridge filled with material and piston which stem is two-stepped. The device has easily removable die and control unit enabling one complete automated control over device operation. The material is placed in closed cartridge smeared with thermostable silicon lubricant. The cartridge is introduced into heating chamber heated to material-melting temperature. The temperature is supported until complete material melting takes place. Pressure is applied to the material and it is pressed out from the chamber into die molding tool cavity. The process is supported until the material is preliminarily cooled. Then, the die is taken off together with the molding tool. The molding tool is cooled to complete material hardening and the article is removed from the molding tool. Then, required cleaning and finishing is done.

EFFECT: high quality of dental prostheses containing no defects.
