Explanation

It refers to a class of medical materials that are directly or indirectly used for the treatment of lesions, morphological repair and functional recovery of teeth and related tissues in the dental medical process. There are many kinds of dental materials, including metals, ceramics, macromolecule polymer, cements and other kinds of synthetic or natural materials. According to their uses, they can be divided into: ① filling materials, materials used to fill cavities when treating caries, and temporary filling materials according to their firmness and solubility in saliva, such as zinc oxide-eugenol cement, zinc phosphate cernent, etc; Permanent filling materials, such as silver amalgam, composition resin, etc.; ② demure materials. materials used to make various artificial teeth, bases, retainers, connecting rods, crowns, bridges and inlays when repairing defective teeth or missing dentition; ③ Impression materials, materials used to record the anatomical morphology of teeth and oral soft tissues and their relationships, such as alginate elasticity impression materials, synthetic rubber elasticity impression materials and impression pastes; ④ model materials, such as gypsum, artificial stone, low melting alloy and model wax; ⑤ Bonding materials, materials used for bonding between tooth hard tissues and materials or products such as plastics, metals and ceramics, such as dental cements and synthetic resin adhesive; ⑥ implant materials, materials used to make dental implants, including titanium and its alloy, stainless steel, ceramics, synthetic macromolecule materials and composite materials; ⑦ Preventive health care materials, materials used to prevent diseases and injuries of teeth and their supporting tissues, etc.; ⑧ Auxiliary materials, such as foundry embedding materials, grinding polishing materials, etc.
