Problems solved by technology

[0004] In the process of making the denture base, it is necessary to fill in the denture base template, and form the denture base through heating, curing and cooling to form the denture base, and some denture bases are made of resin, and the denture base and the denture base template There is a large difference in materials, so the thermal expansion and contraction coefficient of the denture base is much greater than that of the denture base template, which easily leads to deformation of the denture base during the heating process, resulting in poor molding accuracy of the denture base

Abstract

The present invention relates to the technical field of denture dental models, in particular to a denture base template and its processing technology. A denture base template includes the following components in parts by mass: 15-25 parts of heat-curing denture water ; 25‑30 parts of heat-curing toothpaste powder. By adopting the above technical scheme, the denture base template is made of thermosetting tray water and thermosetting tray powder, so the overall main component is also a resin material, which is similar to the denture base material, so it also has similar properties. Thermal expansion and contraction coefficient, so during the heating and cooling process of the denture base template, the denture base template and the denture base can produce close expansion and contraction, thus avoiding the denture base template being squeezed by the denture base template after expansion The occurrence of deformation ensures the stability and accuracy of the size of the denture base.

Description

technical field [0001] The invention relates to the technical field of denture dental molds, in particular to a denture base template and its processing technology. Background technique [0002] A denture base is the part of a removable partial denture that connects artificial teeth to the denture. The base covers the alveolar ridge of the missing tooth, which can connect the various parts of the denture into a whole. It is the base for arranging the artificial teeth, and evenly transmits the force borne by the artificial teeth to the bracket on the oral tissue. Made of metal and / or resin. [0003] In the process of processing the denture base, the denture base template is an important tool, so the accuracy of making the denture base template will directly affect the production quality of the denture base. In the prior art, in order to ensure the stability of the denture base template, it is mostly made of corrosion-resistant high-strength metal. [0004] In the process o...
