Types and Prices of Porcelain Crowns Depending on the material used for the inner crown of the porcelain crown, there are mainly nickel-chromium porcelain crowns, cobalt-chromium porcelain crowns, titanium porcelain crowns, pure titanium porcelain crowns, gold-platinum porcelain crowns, gold-deposited porcelain crowns, and all-porcelain cast porcelain crowns and zirconia all-porcelain crowns. Here I come to outline the different types of porcelain crowns and the approximate price of each type, hoping to give you a little insight into the process of choosing porcelain teeth to have some help. Nickel-chromium porcelain teeth, also known as base metal porcelain teeth, is the first decade of the most domestic porcelain teeth, nickel-chromium alloy corrosion-resistant, inexpensive, medical nickel-chromium alloy, mainly composed of nickel, chromium and a small number of other metal elements harmless to humans; of which 77.95 percent nickel, chromium 12.60 percent. The chemical nature of nickel is relatively not particularly stable, in the complex oral environment, exposed to the oral metal part will slowly decompose and release black oxide, resulting in local gum tissue staining, some of the more sensitive people will form gum black line, is because this type of porcelain crowns in the metal ions easily precipitated, precipitated in the mouth sometimes there is a faint metallic odor, while the precipitated Metal ions will also be deposited in the cervical edge of the gums, so that the gums become black, which is why the cervical edge of the teeth of people with nickel-chromium porcelain veneers is easy to blacken, affecting the aesthetics of the reason. Although dental nickel alloys also have metal particles precipitation, precipitation of metal particles have a certain degree of toxicity, but the rate of metal particles precipitation is very slow and slow, the dose is far less than the threshold of toxicity; in the United States and the European Union and other countries, nickel alloys are not currently classified as carcinogenic substances, intraoral use of dental alloys, so far there are no relevant reports on its carcinogenicity. Elemental nickel is allergenic to the human body, so it will cause a portion of people’s gums slightly inflamed, resulting in porcelain teeth and gums in contact with the place of slight redness, damage to gum health, affecting the aesthetics; a few cases will produce systemic allergy symptoms, the population, nickel allergy female proportion of about 15-20%, the proportion of men in 1-2%, there will be an inflammatory reaction of the skin mucosa. Since the introduction of nickel-chromium porcelain teeth in the 1980s, our dentists have produced a large number of nickel-chromium porcelain teeth, so far there have been no reports of cancer and kidney function damage due to nickel-chromium porcelain teeth, even in the United States, nickel-chromium alloy is also used in large quantities for porcelain dental production. Therefore, as long as the production is good, nickel-chromium alloy is safe to use, you can not worry. But it is worth noting that there are some bad dental clinics and porcelain dental processing plants in society in order to reduce production costs, sometimes using industrial nickel-chromium alloy instead of medical nickel-chromium alloy, industrial nickel-cadmium alloy contains some harmful impurities such as beryllium elements, carcinogenic to humans, is strictly prohibited for human use. The clinical charge for nickel-chromium porcelain teeth is between approximately$400 and$600 per unit. Titanium porcelain teeth Titanium alloy is more biocompatible, good toughness, good color, strength is also high, lighter specific gravity, while having excellent porcelain tooth bonding strength, can extend the service life of porcelain teeth, and in the oral cavity stability is relatively high, not easy to oxidation, so that the gum irritation is small, can avoid the phenomenon of gum staining and gum bleeding and other irritation symptoms, its price between non-precious metals and precious metals. The price is relatively more expensive than ordinary porcelain teeth. But the current clinical talk of titanium porcelain teeth in titanium metal content is actually not high, the vast majority of dental medical titanium alloy composition is still nickel, chromium, molybdenum and other metal components, including titanium 4-6%, nickel 60-76%, chromium 12-21%. Theoretically speaking, titanium porcelain crowns and nickel-chromium alloy porcelain crowns essential difference is not particularly large, many people are willing to accept titanium porcelain teeth, the main psychological role and mentality of the reason, because they are worried about the ordinary nickel-chromium alloy porcelain teeth low price is not the quality of the above will be poor, after all, porcelain teeth set up is not a trivial matter, about health, and high-grade precious metal porcelain teeth are more expensive, beyond the Most people can afford, so in this case, the price of the middle of the titanium porcelain teeth into a natural and more reasonable choice. In regular dental hospitals, because titanium porcelain teeth and ordinary porcelain teeth are not very different, doctors are generally reluctant to recommend this type of porcelain teeth to patients, this titanium porcelain teeth and a more easily ignored shortcomings, it is easier to chipped porcelain; and in some places for profit, it is the use of this psychology widely promoted. At present, titanium porcelain teeth clinical charges in 600 yuan to 800 yuan per piece. Gold-plated inner crown porcelain teeth The so-called gold plating is generally in the ordinary base metal inner crown (nickel-chromium) and human tissue contact side of a layer of pure gold, the purpose is to reduce the base metal free and to the oral tissues and the stimulation of the tooth itself. Gold is one of the more ideal restorative materials, with better compatibility with human tissue, less irritation and generally no inflammation of the gingival margin. But gold is expensive, so this gold-plated compromise solution has emerged as a way to achieve similar or similar results to gold porcelain teeth at a low price. On the basis of nickel-chromium porcelain, in contact with the body and gums, such as the inner crown surface of porcelain teeth, through electroplating precision processing, so that the inner crown surface to add a layer of 99.9%, 24K pure gold plating, to close the surface of ordinary metal, to prevent the precipitation of harmful metal ions, in order to isolate the base metal and human contact, effectively avoiding the infringement of human tissue, so as to eliminate the inflammation of the gums and the blackening of the cervical margin This eliminates the chance of gingival inflammation and cervical margin blackening, and prevents the adverse reaction of gum blackening. Gold-plated porcelain teeth is a layer of pure gold plated on the surface of the base metal, this layer of gold is after all plated on, and the gold layer is very thin, so the long-term effect is not very good. The price of titanium porcelain crowns is between 600 and 900 yuan. Our hospital has recently stopped this type of porcelain crowns. Cobalt-chromium inner crown porcelain teeth Cobalt-chromium inner crown porcelain teeth: cobalt-chromium alloy was first used in transplantation medicine, used for hip joint, which is also a sign of its biocompatibility, used to this day. As early as 1929, it was used in dental care, initially for removable partial denture restoration. Cobalt-chromium alloy: mainly developed for the toxicity of Ni and beryllium, its cobalt content is higher than that of nickel-based alloys, generally 25%, and elements such as Cu, W, Nb, Si, Ru, Al and Mo. Because of its high cobalt content, its corrosion resistance is better than nickel-based alloys, and good gold porcelain bonding, and because it contains more chromium, its melting point is higher, there is a certain reaction between the alloy and the embedding material. Porcelain with cobalt-chromium alloy, its elastic modulus of 213745Mpa, the hardness of 335 Vickers hardness. Higher elasticity coefficient, high comfort and no alloy discoloration in the patient’s mouth. It is the ideal alternative to nickel-chromium porcelain teeth. Cobalt chromium porcelain crowns Price is usually around 800-1200. Our hospital 1080 yuan. Pure titanium inner crown porcelain teeth 1 titanium has stable chemical properties and excellent biocompatibility, does not have any reaction with human tissue. Will not cause gum inflammation, cervical edge blackening, oral metal odor and other problems. 2 pure titanium non-magnetic, can be X-ray, does not affect the MRI, X-ray film, CT, etc., does not affect the future medical examination. 3 light weight, less than 1/6 of other porcelain alloy. 4 can be said that pure titanium is the 21st century medical metal, 5 pure titanium also has certain disadvantages, is not easy to process, metal elasticity, in the absence of sufficient shoulder is very easy to chipped porcelain, high technical requirements of the doctor. Of course, the cost of pure titanium porcelain teeth is also higher. Titanium is the ideal metal for oral restorative materials, the current use of pure titanium porcelain porcelain special porcelain powder greatly reduces the chances of chipping, but the color is slightly slightly worse. If the front teeth can prepare enough space is no problem, non-professionals can not see the difference. Pure titanium crown porcelain teeth in the clinic, the price per unit in the 1500 yuan -2200 yuan or so. Our hospital 1680 yuan. Precious metal porcelain teeth, also known as gold alloy crown porcelain teeth, using imported medical gold alloy, which contains 82% to 90% gold, is currently an excellent porcelain restorations, gold stable metal properties determine its better biocompatibility. Gold is an inert metal, physical and chemical properties are very stable, is one of the more ideal restorative materials, and human tissue compatibility is very good, generally will not appear to stimulate the symptoms of inflammation of the gingival margin, and gingival edge blackening problem. Gold alloy porcelain dental shade is better, morphology is also closer to the normal tooth shade, has a good aesthetic effect, the cervical margin part of the good shape, more natural, more in line with the natural human dentin color, while the gold porcelain combination is strong, corrosion resistance is relatively strong, is currently the ideal restoration of porcelain dental crowns, but also a doctor willing to recommend to patients a restoration method. But if the patient needs to take CT, MRI also need to remove. Recently, because of the rapid growth in the price of gold, the cost of raw materials is very high, processing plants are reluctant to make such restorations. Recently our hospital has stopped doing gold alloy porcelain crowns. The current cost per unit of precious metal porcelain teeth is between$2000 and$4000. All-porcelain teeth All-porcelain teeth are one of the most aesthetically pleasing dental restorations, hard, wear-resistant, high compressive strength, natural and pure appearance, crystal clear, realistic color, close to natural teeth. The most important feature of all-ceramic teeth is that they do not contain metal, which is a suitable choice for some patients who are allergic to metal, and because there is no permeability of the metal inner crown, the teeth can still be examined through x-ray. Another important advantage is that it is transmissive to X-rays, which is the best choice for patients who need MRI, because in MRI, if the mouth contains metal, artifacts will be formed in the vicinity, affecting the effectiveness of the surrounding cranial tissue system such as ear, nose and throat and ophthalmology. In the future need to head CT, MRI examination will not be affected, the examination does not need to remove the dentures. At the same time, all-ceramic teeth have very good biocompatibility and safety performance, there will be no allergic reaction to the metal base crown; no irritation to the gums, generally will not appear gum recession, gum greening, gum edge black, gum redness and swelling; has a relatively high strength and toughness, good durability, can be permanently preserved in the mouth, all-ceramic tooth color whether in the light and natural light can maintain the natural color, the reflection of light and The reflection and scattering of light is closer to that of natural teeth, with better aesthetic effects. All-porcelain teeth are composed entirely of porcelain powder, no metal base, light quality, more comfortable to wear; porcelain thermal conductivity is low, there is a good isolation, the pulp is less irritating, more conducive to protecting the health of the pulp. There are two main types of all-ceramic crowns, cast porcelain crowns and CAD/CAM zirconia all-ceramic crowns. There are two generations of cast porcelain teeth, one with cast glass ceramic and white garnet as the inner crown. The second generation uses lithium-based ceramics as the inner crown. The manufacturing process of cast porcelain teeth is to take a mold of the tooth and then cast the whole thing. Cast porcelain crown color is particularly realistic, is the most beautiful of all porcelain crowns, but the degree of strength to play some discount, fragile and easy to chip porcelain. Cast porcelain crown price in 2000-4000 or so. Our hospital 2200 yuan. All-porcelain teeth are made by firing the inner crown with porcelain material. The biggest difference between all-porcelain teeth and porcelain teeth is that the inner crown is made of porcelain, a transparent skeleton, and then the porcelain powder is fired on the outside. Because it does not have a metal crown, it is more suitable for cosmetic restoration of front teeth, all-porcelain crowns have good transparency and refractive, all-porcelain teeth and cast porcelain teeth because they are composed of porcelain materials, with beautiful, good translucent, and enamel similar to the refractive, so the dental cosmetic effect is closest to natural teeth. Porcelain material is the best biocompatible with human body, gum irritation symptoms will not irritate the gums and gum inflammation, gum swelling, bleeding, generally will not have gum discoloration affect the aesthetics, the wear and tear on the teeth together is relatively small. Therefore, because of the advantages of all-porcelain and porcelain teeth with all aspects, is the ideal dental cosmetic technology, to achieve the most close to natural teeth, restoration of metal-free porcelain crowns is a future development trend. Zirconia porcelain teeth is a kind of all-porcelain crowns into the country in recent years, zirconia was originally used as an aviation material, its excellent mechanical properties, has a very high compressive, fracture strength, is currently the most ideal porcelain restoration, can be used for anterior teeth tetracycline teeth, fluorosis, discolored teeth and other cases of bad tooth color cosmetic restoration, can also be used to improve the morphology of the tooth, such as enamel defects, incisal defects For some teeth that have been treated with root canal therapy, it can prevent fracture of the tooth. The biggest advantage of zirconia all-porcelain crowns is high strength, exceptionally strong, good biocompatibility, high precision. It can withstand the more complex functional requirements of the oral cavity, in addition to single crowns can also be made continuous crowns, can be cosmetic and restore missing teeth, the cost is also currently the most expensive restorations. At present, the dental industry mainly provides two systems of zirconia all-porcelain crowns: one is the German company Sironde zirconia all-porcelain crowns, this should be the noble family of zirconia all-porcelain crowns. This is a computer-designed and controlled lathe out of the porcelain crown, precision is very high; the other is the U.S. Zercon (CERCON) zirconia all-porcelain crowns, performance is also quite good. As medical institutions and medical units around the zirconia all-porcelain crowns as a new technology, the introduction of new business, so the clinical fees for these treatments vary more widely across the country in various medical units, the price of each porcelain unit is basically between 3,000-8,000 yuan. Our hospital 4200 yuan. Recently we have added a new Japanese and domestic zirconia porcelain block, performance is also good, the price is more reasonable, our hospital Japanese porcelain block zirconia is 3500 yuan to, domestic porcelain block zirconia is 3200 yuan, domestic is brewing to reduce to 2800 yuan. Of course, porcelain teeth do beautiful or not, wear in the mouth feeling how, in fact, mainly depends on the level of oral surgeon preparation and technician processing production level, do well, in the feeling and real teeth in the appearance and color is almost no difference. In the oral restoration, the material is the basis, technology is the decisive factor. All-porcelain teeth and porcelain dental casting on the doctor’s technical requirements are higher, the doctor needs to have sufficient experience in porcelain preparation, in color, mold, temporary crowns, bonding, etc. are more stringent than the requirements of metal porcelain; at the same time, the technician is also an important part of the porcelain casting operation, porcelain crown production and processing of the technician’s technical level, aesthetic training, observation ability also plays a vital role. We should not because the most expensive is the best, suitable for their own is the most ideal. I sincerely hope this article can help you all! I wish you all healthy teeth and good mood!
