Ceramic dental restorations because there are mainly two: porcelain crowns and porcelain bridges, so wear before each have different requirements, you should first understand the characteristics of these two methods is appropriate to wear again.
A porcelain bridge
Porcelain bridge is mainly used for tooth loss, for not more than two consecutive missing teeth or missing teeth with intervals of not more than four patients. Continuous over three or more missing teeth, missing teeth due to excessive tooth roots overwhelmed porcelain bridge repair will lead to failure, it is not Dental Reviews appropriate to wear. For patients, the ability to install porcelain teeth to follow doctor's recommendations.
What to wear porcelain teeth
Different according to the internal metal frame materials, nickel-chromium alloy porcelain teeth into dental porcelain and precious metals (gold alloy) porcelain teeth. Ni-Cr alloy-porcelain dental cheap Shanghai, for example, a porcelain teeth cost is $ 500. The study found that nickel-chromium alloy of nickel element in the acidic components susceptible to corrosion of saliva, sustained release of nickel ions and deposited on the gums, the formation of gingival edge of the black line, affecting the appearance. In addition, nickel-chromium alloy easily lead to gum allergy, redness and swelling bleeding. Then people began to replace the nickel-chromium alloy with precious metals. As the gold element of stable, good corrosion resistance, in the oral cavity can not easily be oxidized, deterioration, gum will not change color, and gold alloy of the gums without stimulation, non-toxic, does not cause gums allergies and bleeding. But the precious metal more expensive, still Shanghai, for example, a porcelain teeth for 1,200 to 1,500 yuan. Patients should be selected according to their economic conditions, ceramic dental materials.
Second, the porcelain crown
PFM can be used for a variety of dental diseases, and morphological integrity of the teeth, mainly the following fixes:
1, dental caries, tooth trauma, leading to large defect, or teeth (especially front teeth) due to nerve inactivation of black, beautiful effect.
2, tetracycline, dental fluorosis, enamel hypoplasia.
3, genetic and other factors lead to abnormal teeth, small teeth and so on.
4, can not be misplaced teeth orthodontic treatment method, reversing the tooth.
These are the two porcelain dental restoration of introduction, before we wear different treatment for different circumstances, porcelain teeth Treatment of dental pain-sensitive fixed in the mouth, inserts installed easy removal difficult, so be prepared before work wear.
1, if no tooth and periodontal tissue abnormalities, you can direct the repair of porcelain teeth.
2, If you suffer from gingivitis, the gums should be scaling, patients learn appropriate methods of cleaning the mouth and then the porcelain dental restoration treatment.
