Advances in Resin-Based Dental Composite Materials

Abstract

With the continuous development of dental materials, traditional dental materials such as alloy materials and porcelain veneers with the shortcomings of insufficient mechanical properties, susceptibility to secondary damage caused by fracture during use, and poor biocompatibility are gradually being replaced by dental resin composites with better mechanical properties, lower cost, and higher biocompatibility. A dental composite is a kind of dental material, which is made of matrix resin, inorganic filler, initiator system, etc. In this paper, some antibacterial materials, stimuli-responsive materials, and self-healing materials are reviewed. For antibacterial materials, this article introduces composite materials containing natural antibacterial agents, organic synthetic antibacterial agents, and inorganic antibacterial agents respectively. For stimuli-responsive materials, this article mainly introduces composite materials that respond to pH changes. For self-healing materials, this paper introduces the composite materials containing self-healing microcapsules, and briefly summarizes the joint application of self-healing microcapsule composite materials and other modified materials. At the same time, the main development directions of dental composite materials at present are summarized and prospects are presented.
