Porcelain-fused-to-metal tooth is a very mature restoration technique, which has both therapeutic and cosmetic functions. Adult beauty repair is our characteristic,
As far as I know, one is dental implant (just planting one tooth, which is more expensive) and the other is dental inlay (planting one tooth and filling three teeth, because two adjacent teeth have to be treated, so as to make a set of fixed porcelain teeth).

It should be decided according to the individual's specific situation.
Materials for filling teeth are as follows:
(1) agglomeration
What is amalgam?
Mercury is mainly composed of silver, tin, copper and mercury.
Under what circumstances?
Amalgam is the most commonly used filling material, because it is durable and has been widely used for more than a century, and the effect is very satisfactory.
Is silver mercury safe?
According to the statement issued by FDI World Dental Association and World Health Organization in 1995, the ingredients of dental restoration materials including amalgam will only cause local side effects or allergic reactions in rare cases. At present, there is still no scientific literature that amalgam is harmful to human body, so there is no need to worry that this kind of tooth filling will affect our health.
The maximum value of mercury gas stipulated by the World Health Organization is 300-500 micrograms per day. According to the measurement data of a dentist in Sweden, it is found that the average mercury gas inhaled by human body from amalgam filling materials every day is only 1.7ug, which is a high limit of 10%. There are many sources of mercury in our bodies. In fact, we absorb more mercury from fish food than from dental materials. Comparatively speaking, the leakage of mercury gas from amalgam filling materials is very small.
(2) Resin materials
Under what circumstances?
The color of resin material is close to the primary color of teeth, and the effect is very beautiful, so it is mostly used on front teeth. Under appropriate circumstances, resin materials can be used to improve the color, shape and size of teeth and beautify smiles.
exist problem
The process of filling teeth with resin material is very complicated. Resin materials are not as durable as amalgam because they are easy to wear. The main reason is that the resin material may shrink after curing, and a small gap will be formed between the resin composite materials, which may give people with dentin allergy another chance of tooth decay, and the resin composite materials may also absorb the pigments in food and drink, which will turn yellow after a long time.
(3) glass ionic resin
Under what circumstances?
Glass ionomer resin is another tooth color filling material. Usually used near deciduous teeth, gums and teeth neck. It can be attached to teeth, and the fluoride it releases helps to strengthen teeth and prevent tooth decay. Sensitive situations also occur less after filling teeth.
There is a problem:
Its texture is weaker than composite materials and mercury, and it is easier to wear. The color is not as good as the resin material.
(4) Nano and diamond resin
Nano and diamond resin materials are the most advanced high-tech materials for filling teeth, which have the advantages of higher strength and more realistic color.
Clove oil zinc oxide cement powder: also known as temporary cement powder and butoxy paste. Used as bottom non-load-bearing material of deep hole double bottom, or non-load-bearing single bottom material, as temporary hole sealing material for 1 ~ 2 weeks, as root canal filling material, with excipient as periodontal plugging agent.
Calcium hydroxide cement powder: it is a new type of pulp-protecting matrix material. Used as the base material of class III and V cavities, used as the base material for protecting dental pulp to block the stimulation of composite resin on dental pulp, and used as direct and indirect pulp capping agent.
Toothpaste: It becomes soft and plastic when heated at 40℃ and hardens after cooling. The auxiliary materials used for root canal filling can temporarily seal the cavity or do the temperature test of the teeth after heating.

Do not use alloy materials containing mercury to fill teeth.
Teeth are important organs of the human body, and people need teeth every day except babies. Dental diseases are also very common, and almost everyone has had dental diseases. People with severe dental diseases will lose their teeth, some have decayed teeth, and some even have their whole teeth pulled out. It is best not to use mercury-containing materials for filling teeth and installing dentures.
The results showed that the mercury content in brain and kidney tissue of people with amalgam fillings was significantly higher than that of people without amalgam fillings. After filling teeth with amalgam, when chewing, mercury can volatilize from the filler and be absorbed by the human body into the blood circulation. Long-term intake of a small amount of mercury can cause chronic poisoning. Mercury has a specific affinity with sulfhydryl groups in protein, which can inhibit the activities of various enzymes, and has a variety of toxicity to the nervous system, which can cause symptoms such as excitement, agitation, anxiety, irritability or depression, apathy, timidity and lack of self-confidence. Kidney damage can lead to proteinuria and renal dysfunction.
Therefore, attention should be paid not to use amalgam materials to fill teeth. There is evidence that the mercury content in the pituitary gland of dentists with amalgam fillings is 40 times higher than that of ordinary people. Therefore, in order to protect themselves, dentists should widely promote the filling technology of mercury-free polymer filling materials to reduce the harm of mercury pollution caused by grinding amalgam. Some scholars have found that mercury pollution around crematoriums is quite serious. In some crematoriums, the mercury content per cubic meter of air exceeds 1mg, which is 1000 times of the upper limit of mercury vapor in air. The main reason is that the amalgam filler in the mouth of the corpse should be removed during incineration or the gas discharged during incineration should be filtered by activated carbon.
Detailed description of filling material type
There are many kinds of materials for filling teeth, and different materials should be selected according to different situations.
(1) According to the properties of materials, mercury agent is composed of mercury and alloy powder; Resin: synthetic resin composite resin and natural resin gutta percha; Metal salt cement powder: such as zinc phosphate cement powder.
② According to the time that the materials can be kept in the cave, they can be divided into short-term use materials, such as temporary hole sealing materials used in the treatment process, clove oil zinc oxide cement powder can be used within 2 weeks, and zinc phosphate cement powder can be used within half a year; Long-term use of materials, that is, permanent filling materials, to replace the long-term retention of defective dentin in the cavity, such as amalgam, composite resin and so on.
Amalgam: it is an amalgam compound formed by the interaction between mercury and silver-tin alloy powder, which is most used in clinic. Mostly used for class I and II holes that need to bear bite force and class V holes that don't need to consider aesthetics; A hole for the abutment of the snap ring; Filling of post-core or full crown restoration of teeth. When restoring teeth with amalgam, it is necessary to maintain a certain volume to bear the bite force without breaking; Because amalgam is not cohesive with tooth tissue, it is necessary to prepare a box-shaped hole and design a well-designed retention form, so that amalgam and teeth can be closely attached and embedded, and can be well isolated from water, so that amalgam restorations can be firm and lasting.
Composite resin: it is a filling material in which a large number of specially treated inorganic substances are added to organic synthetic resin. With the help of tooth surface treatment technology, it is bonded to the hard tissue of teeth and is mostly used to fill ⅲ and ⅴ cavities. There are also high-strength composite resins that can be used to fill Class I and Class II cavities of posterior teeth. Bonding technology can also be used to repair class IV cavities and teeth with serious tooth defects. Photosensitive curing composite resin, with stable color and strong adhesion, is especially suitable for the restoration of anterior teeth; Although the chemical curing composite resin has slight discoloration, it is simple to operate and is also suitable for the tongue (palate) cavity of posterior teeth and anterior teeth. Polycarboxylate cement powder (also known as polyacrylic acid cement powder): it is a cushion and cement material. It can be used as a cavity bottom material, a cavity sealing material within half a year, a root canal filling material, an adhesive for bonding crowns and bridges of dental restorations, and an excipient can also be added as a periodontal plugging agent.
Glass ionomer cement powder: it is a universal material that can stimulate dental pulp and bind hard tissues of teeth, but its strength is lower than that of amalgam. Suitable for class III and V cavities, used to fill deciduous teeth and used as cavity sealant to prevent dental caries. Zinc phosphate cement powder: also known as permanent cement powder and zinc cement. It can be used as a bearing material for deep holes and double bottoms, as a hole sealing material within half a year, and can also be used for crown and bridge restoration in oral cavity repair.
Clove oil zinc oxide cement powder: also known as temporary cement powder and butoxy paste. Used as bottom non-load-bearing material of deep hole double bottom, or non-load-bearing single bottom material, as temporary hole sealing material for 1 ~ 2 weeks, as root canal filling material, with excipient as periodontal plugging agent.
Calcium hydroxide cement powder: it is a new type of pulp-protecting matrix material. Used as the base material of class III and V cavities, used as the base material for protecting dental pulp to block the stimulation of composite resin on dental pulp, and used as direct and indirect pulp capping agent.
Toothpaste: It becomes soft and plastic when heated at 40℃ and hardens after cooling. The auxiliary material use for root canal filling can temporarily seal that cavity, or the temperature of the teeth can be teste after heating.
Dental implants belong to the field of oral surgery.
This implant is made of titanium. It won't really implant a tooth.
The appearance of dental implants is porcelain teeth, so it looks very close to your original teeth and looks more harmonious with other teeth.
The cost of dental implant varies according to the region, clinic size, population consumption, hospital level and price. If it is a first-class hospital in Beijing, the charge is 1500 RMB, not counting the porcelain teeth restored above.
Because this is a kind of operation, there are certain risks, so hospitals/clinics are required to have certain disinfection facilities, so don't be greedy for petty gain and avoid unnecessary risks.
Dental implants have good appearance. Dental implant is a metal implant mainly composed of titanium in alveolar bone. Because it is also made of titanium, it has good biocompatibility. After the implant is nailed, it needs to wait for 4-6 months, and then the porcelain-fused-to-metal restoration is carried out after the implant is completely combined with the alveolar bone.
Among them, the life span and success of dental implants depend on whether dental implants are completely compatible with alveolar bone and the use of patients after dental implants.
The reason why the risk is high is that the complete compatibility of dental implants is 60%, and 40% of the population will not be completely consistent, which means failure. We have been carrying out dental implants for more than 5 years, and there are about 23 cases of dental implants. There are no unsuccessful cases at present. Now the first dental implant was about 18 years ago, and there are still no bad symptoms.
Secondly, as long as the dental implant has been planted for more than 5 years without adverse reactions and has been used for more than 10 years, it is defined as success by the world medical organization.
The reason why we don't choose the posterior teeth for dental implants is that the upper posterior teeth are close to the floor of maxillary sinus cavity, and improper implantation is easy to pierce the maxillary sinus cavity by mistake, resulting in maxillary sinus cavity infection. Because there is a mandibular canal under the lower posterior teeth, the implant is easy to fall into the mandibular canal too deeply, causing infection.
It is best to choose porcelain restoration. Because porcelain teeth are safer, more convenient, less painful and cheaper than dental implants, it is worth choosing. If only the root is left, you can choose post porcelain restoration to save money and time. Now porcelain restoration is becoming more and more mature. According to the definition, the average life span of dental implants is 8 years, while the average life span of porcelain teeth in China has exceeded 10 years. This is just a suggestion. The specific choice is up to you. However, one thing is clear. No matter which treatment scheme you choose, you must choose a large local hospital (small hospitals are contracted) or a large clinic with certain advanced equipment for treatment, so as to avoid the loss outweighs the gain.

Some supplementary answers to your question:
1. Under what circumstances is the best dental implant!
Generally speaking, it is better to choose dental implants for a single missing incisor, and it is more important for the incisor to be beautiful, with less bite force and no damage to other teeth. Of course, what is important is that young people (from the age of 18) have the funds in place, and the compatibility rate is high and the self-repair speed is fast after dental implantation.
2. What is the difference between dental implants and other dental restoration methods (good or bad)?
Answer the advantages and disadvantages of various fixes.
Advantages of dental implants: no damage to other teeth and surrounding teeth. Good appearance and shape.
Disadvantages: it has a certain failure rate and is expensive.
Clinical charges: Prices vary, and the domestic standard is generally 1500 yuan/A.
Porcelain teeth: precious metal series porcelain with good appearance and good biocompatibility.
Disadvantages: If the missing tooth needs to be trimmed to make a bridge, the jaw is too strong and it is easy to collapse, and the price is relatively high (the international and domestic charges are quite low)
Clinical charges: domestic standard common porcelain 300 yuan/piece.
NP steel crown: Metal crown bears a large jaw force and is not easy to be damaged. Less molars and low price.
Disadvantages: poor biocompatibility, ugly appearance, metallic color,
Clinical expenses: 120 yuan/pill.
