With the economic development and improvement of living standards, beautiful teeth, charming smile is no longer just the patent of celebrities, ordinary people on dental aesthetic requirements are also increasing. Porcelain teeth can change the shape and color of the teeth to achieve the effect of cosmetic dentistry, is now generally accepted. From a professional point of view, the full name of the porcelain teeth – metal with fused porcelain crowns, is a low-fusing porcelain fused to the cast metal base under vacuum conditions on the crown of the gold – porcelain composite structure of the restoration, this restoration both the strength and toughness of metal materials and ceramic materials, beauty and realism, and therefore can meet the ordinary people on the cosmetic requirements of the teeth. Requirements. First, what materials can be selected for porcelain teeth? 1.Precious metal alloy porcelain crowns: gold-platinum alloy porcelain crowns, gold deposition technology porcelain teeth (anterior teeth, single crown) 2.Non-precious metal alloy porcelain crowns: nickel-chromium alloy porcelain crowns, cobalt-chromium alloy porcelain crowns 3.Titanium alloy, titanium crowns: processing difficulties, easy to chipped ceramic, restricting the use of the second, the patient in the choice of what understanding of the misunderstandings? 1, fixed ceramic teeth must be better than the movable teeth This should be based on the patient’s teeth and conditions to choose: such as the degree of looseness of the teeth, the crown root ratio, with or without night grinding teeth and so on. Can not be generalized. 2, porcelain teeth is the best, non-porcelain teeth do not set missing teeth and missing less. Neighboring teeth do not have inflammation or although there is but after treatment has been controlled by the doctor’s examination can be porcelain restoration; color or form of the teeth (such as oral cyclamen teeth, push-shaped teeth), the patient, can consider doing porcelain restoration; due to dental trauma fractured teeth. If the root of the tooth has enough length, periodontal condition and better, after perfect root canal treatment, can be porcelain restoration; due to dental caries (rotten teeth) and other reasons leading to large tooth loss, tooth discoloration, can be restored to the aesthetic and functional through the porcelain teeth. However, if there are more teeth missing in the whole mouth, movable dentures can also be chosen. However, if you have irregular teeth and want to beautify your teeth, it is recommended to consult orthodontic treatment first, because anything is best when it is innate and natural, and teeth are no exception. If you can not accept orthodontic treatment and then choose porcelain or all-ceramic teeth cosmetic restoration, it is recommended that before cosmetic restoration as much as possible to the doctor to consult before and after the restoration of what should be aware of the situation, the doctor of the regular hospitals will also be detailed on your own introduction, which is also responsible for you. 3, gold porcelain teeth is certainly better than ordinary porcelain teeth The better the material of porcelain teeth is not necessarily the better the effect, even if it is gold alloy precious metal porcelain teeth, if the doctor and the technician’s production process is very poor. The quality may not be as good as an ordinary porcelain tooth that is carefully made by doctors and technicians. This is like having a bunch of good food ingredients, the chef’s craftsmanship is not good, the quality of the dish will also decline. 4, regular hospitals and clinics of porcelain teeth look the same, choose porcelain teeth cheaper clinics Currently in the country’s private dental clinics are many, some of the better private dental clinics porcelain teeth prices are much more expensive than public hospitals. Patients are reminded to be aware of the following: there are some small dental clinics where the doctor’s skills are poorer, the teeth that should be treated are not treated, the materials are substandard, the living pulp tooth preparation and post-preparation damages, inferior impression materials, low hardness gypsum, inferior bonding agents, etc., and there are corners cut on all the processes. Even the material of porcelain teeth is also some small denture workshop production, raw materials can not be guaranteed. 5, porcelain teeth are metal, will not be damaged In the oral environment, porcelain teeth especially need maintenance. Marginal bacterial invasion can lead to secondary caries, aggravated gingivitis and tooth loosening. It is recommended that patients regularly find a doctor for follow-up examinations. 6, periodontitis is caused by porcelain teeth Poorly made porcelain teeth can aggravate periodontitis and gingivitis. At the same time, poor cleaning is also likely to lead to gingivitis. 7, metal crown grinding less cheap can be done first, and then change the porcelain teeth later After the full crown is done, the doctor and the patient want to always be able to use. It is not recommended that patients like changing clothes to change the full crown, because even if the doctor is careful, the removal of the crown will have a certain risk; and every redo on the tooth itself is a damage. Therefore, for the choice of materials for full crowns, patients should go as far as possible in one step. “It hurts a little to bite, can I change the material?” Tooth pain may be non-crown, but the tooth. Third, whether the more expensive the better, can you specifically introduce the characteristics of different materials, respectively, suitable for what kind of people, why? Porcelain teeth is not necessarily the more expensive the better, depending on the patient’s teeth and the level of doctors and technicians. From the point of view of the metal material of porcelain teeth, common nickel-chromium alloy, titanium alloy, cobalt-chromium alloy, palladium-based alloy, gold alloy (cytotoxicity is reduced in turn) 1, nickel-chromium alloy porcelain teeth Ingredients: composed of nickel, chromium, beryllium, manganese and other metals. Characteristics: high strength, cheap; very few patients have allergies. 2, cobalt chromium alloy porcelain teeth Ingredients: by cobalt, chromium, manganese and other metals. Characteristics: high strength, cheap. 3.Titanium alloy porcelain teeth Ingredients: titanium, nickel, chromium and molybdenum and other metal components. Features: high metal strength, strong combination with porcelain, good color. 4, platinum-palladium alloy porcelain teeth (also called semi-precious metal porcelain teeth) Ingredients: platinum, palladium, silver and other metal components. Characteristics: corrosion resistance, good biocompatibility, more realistic color, stable performance, not easy to collapse porcelain. 5, gold-platinum alloy porcelain teeth (also called precious metal porcelain teeth) Ingredients: 90% gold, platinum 9.5%, palladium and other metal components. Characteristics: the combination of metal and porcelain is more solid, the edge of the more dense, more beautiful color, but the price is higher. 6, gold deposition of porcelain teeth Ingredients: 99.9% gold content, made of special technology, the accuracy of the ordinary process is impossible to achieve. Characteristics: better protection of dental stumps, crowns, bridges, excellent sealing, biocompatibility, porcelain color realistic, edge of good suitability (suitability refers to the size of the gap between the tooth preparations and restorations, i.e., the thickness of the adhesive medium). . 7, cast porcelain teeth, also known as all-ceramic teeth (metal-free) Ingredients: the inner crown for the lithium-based ceramics, strength can be as high as 420Mpa. process is the prefabricated casting of the porcelain block in the thousands of degrees above the high temperature of the casting of the restorations and then baked porcelain or color. Characteristics: superior in appearance to metal porcelain teeth, color closest to the real teeth, the inner crown of the gums without stimulation, the reflection of light closer to natural teeth. According to their own needs and economic ability to choose the appropriate porcelain crown: 1, the elderly: cheap, harmless to the body can be. Recommended cobalt chromium alloy porcelain crowns. 2, good economic conditions: medium and high-grade, can choose semi-precious metal or precious metal porcelain crowns. 3.General public practical porcelain crowns: cobalt chrome alloy porcelain crowns The actual situation in the oral cavity, according to the patient’s tooth position, aesthetic requirements, occlusal situation, the amount of teeth remaining, the required color shading effect: anterior teeth – anterior teeth restoration, generally preferred to all-ceramic restorations, followed by gold-deposited porcelain teeth or (semi-)precious metal porcelain restorations, and finally the Ordinary porcelain restorations; Tetracycline teeth – porcelain veneers, porcelain crowns, zirconia, and all-porcelain veneers are available. In general, gold deposition of porcelain teeth or precious metal alloy porcelain teeth whether in biocompatibility, corrosion resistance, edge closure, gold and porcelain bonding strength or in the impact of MRI and aesthetic performance are better than non-precious metal alloy porcelain teeth, but non-precious metal alloy porcelain teeth are not useless, it also has the advantages of: lightweight and high strength, the thickness of the base crown can be thinner, you can make up for the aesthetic with a layer of ceramics The price is relatively cheap; corrosion resistance and aesthetic performance can meet the basic clinical requirements. Moreover, the expensive price of precious metal alloy porcelain teeth has only been accepted by a small number of people, which largely restricts the scope of its use in the clinic. Therefore, when patients undergo porcelain tooth restoration, they should consider the characteristics of the various porcelain teeth mentioned above, as well as their own specific circumstances, such as age, aesthetic requirements, economic status, etc., and at the same time, refer to the doctor’s advice to choose the most suitable porcelain teeth. Here need to point out and emphasize that the material of porcelain teeth is not the only factor that determines the clinical restoration effect, in fact, the production process of porcelain teeth and the doctor’s operating techniques also greatly affect the restoration effect, so we recommend that the majority of patients try to go to regular hospitals to get better restoration results.
