Abstract

The invention relates to a nanocomposite resin material, and particularly relates to a dental nano-filler composite resin temporary crown and bridge material and a preparation method thereof. The nano-filler composite resin comprises a body component and a catalyst component, and preferably, the composite resin temporary crown and bridge material is prepared by stirring the body component and the catalyst component according to the mass ratio of 1:1 in practical application. The nano-filler composite resin material is used for preparing a temporary crown and bridge clinically, is steady in the cured shape of a temporary restoration body, and has good color stability and polishing performance. Through the nano-filler with special functions, the wear resistance and strength of the composite resin temporary crown and bridge material can be improved.

Description

technical field [0001] The invention relates to a nanocomposite resin material, in particular to a dental nanofiller composite resin temporary crown and bridge material and a preparation method thereof. Background technique [0002] Resins were first introduced into dentistry in the mid-20th century. It has the advantages of easy operation, good color and low price. However, its mechanical properties are poor, so it was only used to make denture bases, artificial teeth, temporary restorations, etc. in the past decades. With the continuous development of research on resin materials, its mechanical properties have been greatly improved compared with the past. The scope of application is also expanding. Especially in recent years, the progress of resin materials has made many breakthroughs, and has been used in the field of fixed repair. The great progress of resin materials is a new type of composite material proposed by Bowen in the 1960s. It uses Bis-GMA as the resin mat...
