What are the types of dental materials? Mainly includes five categories:
1, *** with consumables
disposable oral examination instrument box, disposable caps / masks / gloves, syringes and rinsing needles, suction spit head, rubber barrier attachment, local anesthetic, cotton balls / gauze and other products, disinfectant products, uniforms / shoes, protective goggles, protective supplies, protective mask, X-ray film / rinse solution, other.
2, orthodontic consumables orthodontic bonding materials
The brackets, arch wire, arch expander, traction device, implant nails / handles, traction ring, chain rubber band, elastic wire, free traction hook, lingual buckle, orthodontic dynamometer, pull hook, ligature wire, orthodontic push / pull spring, band ring / buccal tube.
3. Intraoral consumable materials
Commonly used filling materials, composite resins, bonding agents, acid etching agents, fossa sealants, root canal filling materials, fiber stakes/retaining nails, root canal disinfecting materials, desensitization/anti-caries materials, bleaching supplies, special plastic films, expanding/extraction needles, root canal files, gum tips, shaping tablets, silver alloy powders, small wedges, rubber barriers to prevent moisture devices, dental plaque control products, fluoride materials, oral ulcer films, deactivators, other.
3, extra-oral, implant commonly used surgical materials
Implant materials, implants, steel/titanium plates, fixation nails, artificial bone, other.
4, restorative, technician consumables
Impression materials, temporary restorations, gingival line, trays, denture/resin teeth, abrasives, emery turning needles, cutting trays and slicing sand bars/handles, porcelain powder, porcelain/ceramic materials, alloys/steel, relining and repairing materials, separators/prosthetic cleaners, rubber bowls, wires/meshes, wax products, plaster/knives/saws/scissors, precision attachments, sanding polishing materials, rests/denture powder/water, waxes, overlay materials, crown and bridge materials, welding rods/coals, bite paper, liquids/oils/agents/glue/powder/sand/paste/pens/nails, warranty cards, others.
5, preventive health care materials
There are fluoride gel, fossa sealant and oral protector. In addition, there are cushioning materials, maxillofacial restorative materials, embedded materials, smoothing and polishing materials, and so on.
Two, dental materials mixing skills
1, composite resin dental materials mixing method
According to the liquid and powder 3:7 ratio by weight, take it was placed on a dry and clean mixing plastic board, mixing knife will be added to the powder one by one in the waves, mixing evenly to the thick paste can be. Mixing should be completed in about half a minute. In the operation, mixing instruments should be clean and dry, mixing knife, mixing plastic board and powder, liquid avoid staining phenolic drugs (such as clove oil phenol); mixing powder and liquid ratio should be appropriate, too thin to use inconvenient, and low compressive strength, too much to affect the adhesive force, curing too fast, difficult to use, filler easy to fall off. When operating the mixing knife force uniformity, try to stick to the glass plate, to avoid air mixing into the material and produce small bubbles, to ensure that the material texture is delicate. After mixing, the mixing knife should be wiped clean with alcohol cotton ball immediately to avoid removing it easily after solidification.
2, silver amalgam dental materials mixing method
Mercury and alloy powder according to the weight ratio of 8:5 into a clean, dry mortar and pestle, crushed with quartz grinding, the pressure is about 1.skg, the speed of about 180 revolutions per minute, so that the silver amalgam into a slice, silver luster, delicate and soft. Wear rubber gloves or finger cots to place the ground silver amalgam in the silk cloth, rub for 1 minute and then squeeze out the remaining mercury to be used. Finger rubbing with a twist pronounced metal phase performance is best.
