SINGLE STAGE METHOD FOR PRODUCING TWO-LAYER IMMEDIATE-INSERTION DENTURE USING THERMOSHAPING TECHNIQUES Russian patent published in 2008 - IPC A61C13/20 A61C13/14 

FIELD: medicine.

SUBSTANCE: method involves taking impression and producing plaster model. Working surface of the plaster model is covered with thin insulating Isalgin layer, then thermoplastic materials and thermoshaping apparatus are used. The apparatus has heating element placed below a frame, two thermoplastic plates are mounted on the apparatus frame. The lower one usable as flexible pad is heated from below by means of thermoshaping apparatus and from above by means of additional domestic heating element fixed on tripod. Uniform and matched plate heating and their integration in united layer. When heated enough, the material is molded and then, prosthesis base is cut along preliminarily marked boundaries. The artificial teeth are joined with thermoplastic material using cool polymerization plastic and finished by applying traditional technological process.

EFFECT: high quality, rapid, one stage denture production process; high accuracy in matching prosthesis bed tissues.
