Large hospitals: 690 yuan for nickel-chromium porcelain teeth, 1080 yuan for titanium, 2100 yuan for gold porcelain, 4200 yuan for zirconium dioxide. Small clinics: nickel-chromium porcelain teeth 380 yuan, gold porcelain porcelain teeth 1400 yuan. The same are porcelain teeth, how the price difference is so big? March 12, the reporter in Shenyang City Dental Hospital denture production center after some visits, finally understood the “mystery”. Save money: reduce the material “are said to be good gold porcelain porcelain teeth, why some clinics as long as 900 yuan / piece?” Reporters asked the production center director Zhang Cheng bluntly. Zhang Cheng explained that, for example, the production of a back tooth, need gold 2.5 grams, or 687.5 yuan; imported porcelain powder, 15.6 yuan; sandblasting, wax, hard plaster, etc., 60 yuan; plus some other materials, generally a porcelain dental material costs have to reach about 50%. This does not include the cost of labor, water, electricity, rent, equipment wear and tear. And individual black clinics in the material “save” money on the way. “There are often individual clinics to buy the trimmings at low prices.” A technician took out the firing of the alloy said, this repeated melting over the material composition is not enough, and even quality changes, compression, folding, corrosion resistance are not good, and the combination of porcelain is not good, with this material out of the teeth, installed in a few days will fall off, chipped porcelain. “Low-priced porcelain teeth used in the color of gold is also not enough.” Zhang Cheng said the center with the gold content of 88.7%, while individual clinics with only 10-15%, even with copper instead. As for the porcelain powder, bonding agent, etc., small clinics often use poor quality materials to muddle through.” Save money: steal work outpatient examination and consultation, take dental impressions, intraoral design, material selection, model confirmation …… do a porcelain teeth, the outpatient part has to go seven or eight procedures. To the production part, it is more complex, filling the mold, wax type, high temperature electric baking, shading, porcelain, quality inspection …… more than 40 processes. “Flowing operation, a tooth also have to do 5 days.” Zhang Cheng said. And in some small clinics, the teeth can be set after three days after extraction, a tooth a week to get it done, which is obviously a big saving in the process. Vacuum mixer, high-temperature electric baking oven, high-frequency centrifugal casting machine, pen sandblasting machine, ultrasonic oscillation cleaning machine, laser spot welding machine …… in the production of more than forty processes, a porcelain tooth to go through dozens of hands, fifteen or sixteen professional machines, many processes on the room temperature, humidity, dust, hygiene and other strict requirements. Save money method: manpower waste plant into processing workshops, low cost to hire people, do insurance, dry carpenter, can be on duty to do porcelain teeth, not to quality requirements, individual clinics in the manpower to save a large sum of money. Zhang Cheng introduced, now a qualified mechanic is not only if the restorative dentistry technology graduate undergraduate, junior college students, and to have years of extensive experience in the production of dental technology. Experts reminded the public, dental implants is not a trivial matter, should go to a regular hospital stomatology, check whether the medical unit is fully documented, the doctor has no license to practice, the product has no quality assurance card, so as to set the quality of reliable, reasonably priced porcelain teeth.
