Description

Technical Field

[0001] This invention belongs to the field of polymer materials technology, specifically, it relates to a high-strength medical resin. Background Technology

[0002] Resin-inorganic filler composites not only closely resemble natural teeth in terms of strength, hardness, wear resistance, polishability, and color, but also possess various functions such as fluoride release, photochromic diagnostic properties, and light transmittance and scattering properties similar to natural teeth. They are increasingly widely used in dental repair and reconstruction. It is foreseeable that, due to their comprehensive advantages in aesthetics and performance, resin composites will completely replace traditional inorganic and metallic materials. However, resin composites have a fatal weakness: volume shrinkage during polymerization and the resulting polymerization stress. If the bonding surface cannot withstand this stress, shrinkage gaps of approximately 2 to 10 μm in size will appear, leading to secondary caries and triggering sensitive teeth.
