Taking Digou Dental Material Network as an example, dental materials can be divided into public consumables and special materials. Specialized materials are divided into oral, extraoral, prosthetic, orthodontic, mechanical, oral health care and other consumables.
(1) * * * Disposable oral examination instrument boxes and consumables, disposable hats/masks/gloves, syringes and irrigation needles, salivary gland suction heads, rubber barrier accessories, local anesthetics, cotton balls/gauze and other supplies, disinfection supplies, work clothes/shoes, protective glasses, protective supplies, protective masks, X-rays/irrigation solutions, and others.
(II) Oral consumable materials, composite resins, adhesives, etchants, pit and fissure sealants, root canal filling materials, fiber posts/retention nails, root canal disinfection materials, desensitization/caries prevention materials, bleaching products, special plastic films, hinges/hinge needles, root canal files, gutta percha tips, irregular pieces, silver alloy powder, wedges and rubber barriers, which are commonly used as filling materials. Such as ① filler material. Repair materials used to fill holes in caries treatment. Temporary filling materials are used for several days to several months, mainly including zinc oxide eugenol cement and zinc phosphate cement. Permanent filling materials can be used in oral cavity for several years to decades, mainly including amalgam and composite resin.
(three) surgical materials, implant materials, implants, steel plates/titanium plates, retention nails, artificial bones and others commonly used in oral cavity and implantation. Such as: implant materials. Materials for making dental implants. Implants can be implanted into soft and hard tissues of oral cavity by surgery to replace some living tissues or whole organs and restore their appearance and function. Commonly used are titanium and titanium alloy, stainless steel, cobalt-chromium alloy, acrylic resin, silicone rubber, bioceramics, composite materials and so on.
(4) Orthodontic consumables: orthodontic adhesive materials, brackets, archwires, arch expanders, traction devices, implant nails/handles, traction rings, chain rubber bands, elastic wires, free traction hooks, lingual buckles, orthodontic dynamometer, traction devices, ligating wires, orthodontic push/pull springs, belt rings/buccal tubes,
(5) Restoration, temporary restoration, gingival retraction line, tray, denture/resin teeth, abrasive tools, emery rotary needles, cutting discs and chip belts/handles, porcelain powder, porcelain/ceramic materials, alloy/steel, heavy lining and restoration materials, separating agents/denture cleaners, rubber bowls, steel wires/nets, wax products and gypsum. Denture/tooth powder/water, wax, embedding material, crown and bridge material, covered electrode/welding coal, occlusal paper, liquid/oil/agent/glue/powder/sand/paste/pen/nail, quality assurance card and others. Such as: ② impression material. Materials used to replicate the anatomical morphology of teeth and oral soft tissues and their relationship. Commonly used are alginate, synthetic rubber elastic material, impression gypsum and impression paste. ③ Model materials. Materials for making various oral tissue male molds. Mainly gypsum, artificial stone, low melting point alloy, model wax, etc. ④ Denture materials. It is used to make various dentures, bases, retainers, connecting rods, crowns, bridges, inlays, etc. when repairing defective teeth or dentition. Commonly used are metals, ceramics and synthetic resins. ⑤ Adhesive material. It is used for bonding hard tissues of teeth with plastics, metals, ceramics and other materials, such as bonding teeth, bonding fixed restorations or fixing orthodontics. Commonly used are cement and synthetic polymer materials.
(6) preventive health care information 6 preventive health care information. Materials for preventing diseases and injuries of teeth and their supporting tissues. Fluorescent gel, pit and fissure sealant, oral protector. In addition, there are bedding materials, maxillofacial repair materials, embedding materials, polishing materials and so on.
