Generally speaking, dental fillings are currently used basically all resin, just because the resin family is too large, too many brands produced at home and abroad, the choice is more troublesome, but it is recommended to use the resin of the Western European or prismatic beauty can be
Resin has the advantage of color, hardness is more closely related to the advantages of the natural teeth, and some resins have a beneficial release of ions, and better *** Dentin restoration. Its only drawback compared to metal is that hard-set shrinkage, which can lead to poor marginal seal, which is also compensated for in the addition of many current resin adhesives and couplers. For many strenuous sports, pressure changes in sports do not have a disproportionate impact.
What are the most cost-effective materials for filling teeth?
Love teeth find Ai teeth Yinchuan Ai teeth dental hospital The following is a variety of materials to learn from it
One. Silver amalgam (Amalgam)
Composition: a mixture of silver, tin, zinc, copper and mercury, with mercury content close to 50%.
Type: conventional (unbonded).
Use: posterior filling.
Maintenance: at least 10 years or more.
Cost: the most economical filling material.
Advantages:
1, good compressive strength, can resist the pressure of chewing.
2, most economical.
3, Treatment can be completed in one visit.
4. Compared with composite resin, it requires less moisturizer in the filling process.
Disadvantages:
1. Not matched with the color of teeth.
2, over time silver amalgam will be corroded, lose its luster, and can also cause discoloration of the dental tissues in contact with it.
3. Traditional amalgam cannot be bonded to the teeth.
4. Box-shaped cavities need to be prepared for filling amalgam, for which the dentist may have to grind away more tooth tissue.
5. Many people may be sensitive to mercury or mindful of its adverse effects, although studies have shown that the amount of mercury the body takes from fillings is similar to the amount the body takes from nature.
II. Composite Resin (positeResin)
Composition: consists of a resin matrix and an inorganic filler.
Types: direct and indirect. A direct filling is a material that is placed on the tooth by the dentist and cured with a blue light. Indirect fillings are prepared and modeled by the dentist on your teeth, then the dentist or technician creates a filling on the model, and then the dentist glues the filling onto the tooth during the second visit.
Usage: Suitable for fillings of all sizes, especially in the front teeth and visible parts, and also for making inlays.
Duration: at least 5 years.
Cost: more than amalgam, but less than gold.
Advantages:
Matches the color of the tooth
Direct fillings can be done in one visit, inlays require a second visit.
Composite resin forms a bond with the tooth tissue, making the tooth stronger than with silver amalgam fillings.
Less tissue is removed than with amalgam. This is due to the fact that the resin material bonds to the tooth tissue and does not require the preparation of a special cavity shape to support it.
Indirect fillings and inlays are heat-treated, a process that increases the strength of the resin.
Composite resin materials can be used in conjunction with other materials, such as glass ions that allow the advantages of both materials to be realized.
Disadvantages:
More expensive than silver amalgam.
Although resin materials continue to improve in terms of strength and abrasion resistance, it is still uncertain whether they are superior to silver amalgam in terms of long-term performance.
Resin materials can shrink, creating a gap between the filling and the tooth tissue, which sometimes grows larger. To avoid shrinkage, the surgeon has to spread it as thin as possible with each filling.
Because the filling needs to be done layer by layer, it takes more time and effort.
Indirect fillings and inlays take two times to complete.
iii. CastGold
Composition: gold alloy (a mixture of gold and other metals).
Uses: inlays, high inlays, crowns.
Maintenance time: at least 15 years or more.
Cost: more expensive than other filling materials, 6-10 times more expensive than amalgam.
Advantages:
Does not corrode
Many people prefer the color of gold alloys.
Has better durability and lasts longer than any other filling material.
Disadvantages:
At least two treatments are required, the first time the doctor will take an impression of your teeth and make a temporary filling. The gold alloy filling will be made on the impression and the doctor will put it in at the second follow-up appointment.
They are more expensive because of the high price of gold and the craftsmanship involved in making them.
If there are gold alloy and silver mercury fillings on two adjacent teeth, there is a risk that an electric current will flow between them, causing you discomfort.
It does not match the color of your teeth.
iv. Ceramics (Ceramics)
Composition: porcelain.
Uses: inlays, high inlays, crowns, veneers, implants, and orthodontic attachments.
Maintenance time: more than 7 years.
Cost: more than composite resins, comparable or even more expensive than gold alloys, depending on the type of filling.
Advantages:
Close to the color of the teeth.
Less prone to staining and wear.
Disadvantages:
More fragile than composite resin materials.
Ceramic inlays or high inlays require more volume to avoid fracture, which ......
What material is good for filling
Wanzong dentist said that today's commonly used filling materials are amalgam, composite resin and glass ion, each material has its own advantages and indications, different dental conditions, of course, the choice of filling materials are different, according to the specific situation to determine the tooth decay fillings need to choose wear-resistant materials, the material is not the same as the material used to fill the tooth decay, but it is the same as the material used to fill the tooth decay. At present, composite resin materials, silver amalgam can be. In any case, reasonable application, in order to receive a good restorative effect
General fillings with what materials
Selection of filling materials Filling materials should be non-toxic, wear-resistant, compressive strength, fill the volume does not change, and the cavity close to the saliva is not corroded or dissolved, easy to operate, and the color and luster of the performance of the aesthetics and so on. However, at present there is no material that fully meets the above performance, only according to the defective part of the tooth, the size of the force and the requirements of aesthetics, such as the selection of a more suitable filling material. Generally, silver amalgam is used in the back teeth, and resin is used in the front teeth, especially in the parts that affect the aesthetics. Amalgam. By containing silver (65%), tin (25%), copper (6%), zinc (2%) alloy powder and mercury according to the weight ratio of 5:8, mixed and ground into. It is a paste with plasticity, which starts to harden after 15 minutes and completely hardens after 24 hours. Therefore, the filling should be completed within 15 minutes and the chewing function can only be exercised 24 hours after filling. Silver amalgam is silver gray, filling the front teeth is not beautiful; and thermal conductivity, so deeper cavities should be adhesive cushion, so as not to conduct temperature *** pulp. In recent years, has developed a successful high copper alloy, that is, the alloy to increase the content of copper, reduce the content of silver. It can improve corrosion resistance, increase strength and reduce volume change. ② Composite resin. Beautiful color, easy to operate, strong adhesion with enamel. Due to poor abrasion resistance, it is mostly used only for anterior teeth. (iii) Adhesive powder (cementum) class. Zinc phosphate adhesive powder for the zinc oxide-based powder and phosphoric acid-based liquid blend, adhesion, but insufficient strength, and can be dissolved in saliva, so it is not suitable for use as a permanent filling agent, mostly used for filling silver amalgam cushioning, or used to fill the milk teeth. Polycarboxylic acid adhesive powder is higher than zinc phosphate adhesive powder strength, adhesion, solubility is small, and no *** effect on the pulp, non-toxic, the use of zinc phosphate adhesive with the same
Filling with what materials
At present, dentistry commonly used dental fillings materials such as amalgam, composite resins, zinc phosphate adhesive powder, glass ionomer adhesive powder, visible light curing composite resin, and so on. These materials have their own advantages and disadvantages, reasonable application, in order to receive a good repair effect. Silver amalgam is made of white alloy powder and mercury alloy, it has the advantages of strong plasticity, high compressive strength, insoluble in saliva, etc., but it is grayish-white in color, not beautiful, so it is mostly used for filling of posterior teeth. And because it is a metal product, is a good conductor, can conduct cold, heat ***, also limits its use. Zinc phosphate adhesive powder has a certain degree of adhesion and no conductive effect, but due to the presence of free phosphoric acid zinc phosphate adhesive powder, the pulp has a certain degree of ***, and can be dissolved in saliva, so it is used as a temporary filling material or filling of milk teeth. Glass ionomer adhesive powder adhesion is good, on the pulp *** small, insoluble in saliva, the color is similar to the color of the tooth, can be used for anterior tooth restoration and wedge-shaped defects in the filling. Chemical curing composite resin and visible light curing compound resin, good hardness, second only to silver amalgam, color similar to natural teeth, good stability, insoluble in saliva. Especially visible light curing compound composite resin has plasticity, there is ample time for filling, reconstruction of the shape of the tooth, and light irradiation polymerization and teeth bonded firmly, high hardness, can be immediately polished. ② The color of the filling is very close to the natural tooth color, and the aesthetic effect is ideal. ③Wide range of treatment, can be used for the fossa closure of abraded teeth, the restoration of fractured teeth, the closure of anterior gaps, the coverage of tooth surface defects and discoloration of teeth, filling of posterior teeth, loose teeth fixation, excessive abrasion of the biting ■ ■ ■ ■ ■ ■ surface restoration, and so on. Why can't I use zinc oxide clove oil paste cushion when filling with composite resin? What is the solution to the clinical use of composite resin or glass ionomer adhesive powder filling tooth defects, can not use zinc oxide clove oil paste bottom. This is because the oil can destroy the ionic reaction between the polymers in composite resins or the carboxyl groups in glass ionomer cementing powders and the calcium ions in the tooth tissue. Also having a destructive effect are chloroform and alcohol. In summary, clove oil, chloroform, alcohol can lead to composite resin paste curing poorly, affecting the filling effect, resulting in secondary caries or filling material off. The main solutions are: ① composite resin or glass ionomer cementitious powder filling, calcium hydroxide can be used as a cushion material. ② If the teeth have been successfully filled with zinc oxide and clove oil paste for permanent filling, you can leave a layer of zinc oxide and clove oil paste, and then pad a layer of zinc phosphate adhesive powder. The outermost layer is filled with composite resin or glass ionomer cement.
What is the difference between the materials used for filling
The first thing to consider is the safety of the material used for filling (the safety of the filling materials used in dentistry is not a problem now), followed by the effect of the filling: functionality and aesthetics, which is based on the requirements of the individual to choose. Below is my summary of the characteristics of the different materials, if you are interested in the specifics.
Summarize put in front:
Aesthetic: resin & gt; glass ion & gt; silver amalgam
Prevention of secondary caries: glass ion & gt; resin & gt; silver amalgam
Hardness: silver amalgam & gt; resin & gt; glass ion
Resin is still the best fillings material, especially the modern development of resin, its hardness, anti-caries and anti-dental materials, the hardness of resin, glass amalgam and glass ion
The best filling material. The development of resin, its hardness, caries resistance, the pulp of the *** sex, some people's allergies and other shortcomings continue to improve, there has been a tendency to replace the first two filling materials, individuals are still respected for filling materials resin.
(A) amalgam: a special type of alloy, can be formed by mercury and silver, tin, copper and other metals.
Advantages: 1. more wear-resistant; 2. cheaper. Unrecorded hospital dentistry Shen Song
Disadvantages: 1. and tooth tissue has no adhesion, can only rely on mechanical locking cooperation embedded in the teeth, so you need to grind the teeth to a certain depth and size of the hole shape, grinding a larger amount of teeth 2. silver mercury filling body and teeth between the cavity of the micro-leakage is larger, it is more likely to secondary caries; 3. color is not good, and can not be used to fill in the teeth near the front; 4. Strong thermal conductivity, deep cavities must be cushioned, easy to postoperative sensitivity; 5. Silver amalgam will have a small amount of free mercury released before hardening
The application of silver amalgam is currently controversial, and it has been reported that mercury can be volatilized from the filling and absorbed by the body into the blood circulation when chewing after filling silver amalgam. Long-term ingestion of mercury in small amounts can cause chronic poisoning and can cause kidney damage, and mercury can cause allergies in some populations.
(ii) glass ionomer cement: it is made of glass powder reacting with polyacrylic acid; generating polymer containing ionic bond
Advantages: 1. Fluoride ions are released, which can prevent secondary caries to a certain extent; 2. There is a chemical bonding of enamel and dentin better than that of silver amalgam; 3. Better marginal closure; 4. Smaller *** sex on pulp; 5. Biocompatibility with human body Better.
Disadvantages: appearance is not as good as composite resin, and opaque; not easy to polish; most of the glass ionomer hardness and bonding with the dentin is lower than resin.
Glass ions are now widely used for bonding, filling, lining and cushioning. Usually I-type glass ionomer cementum is mainly used for crowns, bridges, inlays and other fixed restorations, cementation, Ⅱ-type is mainly used for the repair of dental defects, such as filling and repair of milk teeth, permanent teeth cervical wedge-shaped defects in the restoration of the Ⅴ, Ⅳ class hole filling and repair, Ⅲ-type is mainly used for the hole lining and pad base; light-curing glass ionomer cementum can be used for wedge-shaped defects, Ⅲ class holes, Ⅲ class holes, Ⅲ class holes, children's Ⅰ, Ⅱ class holes and pile nuclei. Repair.
Plus the advantages and disadvantages of composite resin materials.
(3) Composite resin: based on acrylic resin, with the addition of glass, quartz and other particles for strengthening purposes;
Advantages: 1. The color and texture is close to the tooth tissue, so the resin filling body has become the first choice of material for filling defective anterior teeth; 2. There is adhesion to the tooth tissue, relatively low requirements for the shape of the cavity, the amount of grinding is relatively small, which is conducive to the protection of dental tissues; 3. It can be used to fill the large area of the defective teeth; 4. The edges of the cavity are closed, which is conducive to the prevention of secondary caries; 5. There is a special resin used for filling posterior teeth, which is both beautiful and strong. The resin can be used to fill the back teeth, which is both beautiful and strong, and can completely replace the silver-mercury material; 6. The thermal conductivity is weaker than that of silver-mercury, and the postoperative reaction is smaller if it is operated correctly.
Disadvantages: 1. A small number of people will be allergic to the resin material, need to change to other materials for restorations; 2. relatively high cost
(D) glass ionomer resin: (in general, it is still a kind of resin, which can be subordinate to the third category) made of glass ionomer and composite resin composite;
has the characteristics of the glass ionomer and the composite resin is beautiful, Degree of damage resistance than the glass ionized water portal is superior, but not as easy to use than the composite resin composite resin; ... >>
What is the best material for dental fillings
At this stage, the main materials for dental fillings are silver mercury, resin materials, glass ionomer resins, nano, diamond resins, etc.
Silver mercury, resin materials, glass ionomer resins, nano, diamond resins and so on.
Silver-mercury, the most commonly used filling material, is one of the components of dental restorative materials, including silver-mercury, which can cause localized side effects or allergic reactions in very rare cases. There is still no scientific evidence that silver mercury is harmful to humans.
Resin material, the color is close to the original color of the teeth, the effect is very beautiful, so most of them are used in the front teeth. However, due to the complexity of this material, and not as durable as silver mercury, the number of people who use it is not as high as silver mercury.
Glass ionomer resin is another tooth-colored filling material. It is usually used on baby teeth, near the gums and neck. However, it is not as aesthetically pleasing as the resin material.
Nano and diamond resin, the nano and diamond resin materials used, are the most advanced high-tech materials for tooth filling fillings, they have the advantages of higher strength and more realistic color.
As for what material you really want to use, it is recommended that you go to the hospital to do an oral examination, so that the doctor for you to develop a program that best suits your own situation.
I wish you a speedy recovery!
What material is good for filling
Composite resin is used for filling, and there are more types of composite resin on the market now, and its hardness and other properties have been greatly improved. Composite resin is more expensive than amalgam, but it is beautiful and environmentally friendly.
Special attention is paid to the low expansion of composite resin, so composite resin repair is a very technical operation, it is recommended that you go to a regular hospital for treatment.
What kind of material is used for filling?
Filling generally do not need to play anesthesia, but filling deep caries is generally more acidic, if the patient can not tolerate can also play a little, but it is best not to play, because playing will hinder the judgment of pulp vitality. If it is to do root canal treatment, generally open the pulp when to play anesthesia. Dental filling materials currently have a lot, before the main silver mercury, it is best not to swallow may be harmful to the body. At present, the filling materials are basically different resin, that generally will not fall into the stomach, filling in the teeth soluble is also very small, basically no harm to the body. The life span of the fillings is related to your own use and maintenance.
Guidance:
Regarding root canal treatment, it is generally applicable to the treatment of teeth with pulpitis or pulp necrosis. It is roughly divided into three steps, root canal cleaning, root canal preparation and root canal filling, and the cost is usually based on the number of root canals, and the number of treatments is about 2-3 times.
What material is good for big teeth filling
The materials for big teeth filling are as follows: 1, light-curing composite resin This filling material is the most commonly used at present, especially for big teeth filling. The color of this material is similar to the color of the tooth, and it is difficult to see the difference after the filling. And there are a variety of different colors to choose from, the dentist will pick the closest kind of color to give you fillings in the big teeth. 2, silver mercury material, this kind of big teeth fillings materials can not be said to have a long history. It is said that long time ago someone started to use this kind of material to fill the big teeth, and now there are still a lot of people who will choose silver mercury to fill the big teeth, because it is affordable, and the effect after filling is also good. However, the biggest disadvantage of using silver mercury to fill large teeth is that it is not beautiful, because its color is black and grey, so it is not suitable for filling large teeth. If it is the previous fillings, now do not think it looks good how to do, do not worry, you can still ask the dentist to use the resin material to give you a new fillings. 3, glass ionomer filling this material is more beautiful than the silver mercury, but the aesthetic is not as good as the resin material. Because the glass ion can only be completely solidified after 24 hours, so it is best not to brush your teeth for a day after filling. 4, root canal temporary sealing material to do root canal treatment is the most troublesome, at least to come *** run 3 times. During this period, the doctor will be the hole in the tooth with sealant temporarily sealed up. These materials that play a role in temporary large tooth fillings are usually fully cured within 7 hours, and it is best not to brush your teeth within 2 hours after root canal treatment. The experts at JK Dental Hospital said that the above materials are better materials for large tooth fillings, but everyone's situation is different, so you have to go to a professional dental hospital to do a checkup to determine the right material for your large tooth fillings.
