What is the difference between porcelain teeth and all porcelain teeth? How long do they live?

Porcelain tooth is a modern means of restorative tooth restoration. It is a restoration method that uses casting *** as the supporting core in the part of the missing or missing tooth, and then uses porcelain on the outside to achieve a similar color and function to the real tooth.

At present, the types of porcelain restoration commonly used in clinical practice are roughly as follows.

1. All-ceramic glazed porcelain veneer: If the tooth does not have a large defect, but only has a poor color, it is recommended that you use this restoration method to achieve a near-perfect aesthetic effect. It is by evenly grinding off a layer (about 1mm) of the surface of the labial and buccal side of the tooth (the side facing the outside) and then reshaping the shape and color of the tooth with a special dental porcelain material, because the tooth color index can be accurately controlled, so the cosmetic effect is very good, and the wear resistance is similar to that of the tooth;

Advantages: The amount of tooth grinding is only equivalent to about 1 2 of conventional porcelain restoration, and it does not destroy the hard tissue of the adjacent point and the lingual tooth, and the taste does not change.

Disadvantages: The retention force comes entirely from the adhesion force, and it is easy to fall off when subjected to excessive external force. Generally, it is only used for cosmetic anterior teeth.

2. All-ceramic crown: evenly grind off one layer of each outer surface of the tooth (after about that, cover the entire tooth with a special all-ceramic material to restore the shape, function and beauty of the tooth.

Advantages: no metal inner crown, the aesthetic effect is very good, and the strength is higher than that of porcelain veneers;

Disadvantages: The amount of tooth tissue is relatively large, and because the all-ceramic crown has a certain transparency, if the tooth itself is heavier, the internal color will be revealed after wearing, so the restoration is most suitable for the pulp tooth with a large defect in the tooth itself or the residual crown repaired with the tooth color pile core;

Due to the limitations of the strength of the material itself, the above two restoration methods are generally only suitable for anterior teeth. The posterior teeth have high requirements for strength, and are generally repaired with porcelain crowns.

3. Porcelain crown: evenly grind off a layer of the outer surface of the tooth (about later, use metal as the inner layer of the crown, and sinter it on the metal surface with special porcelain materials for dentistry, so as to restore the shape, strength and beauty of the tooth, due to the existence of a metal inner crown, the mechanical strength is higher than that of porcelain veneer and all-ceramic crown, and the disadvantage is that because the color of the metal inner crown is to be covered, the color of the porcelain layer needs to be used, which will make the tooth color layering and realistic feeling poor. According to the different materials of the inner crown, the porcelain crown is mainly divided into nickel-chromium alloy porcelain crown, titanium cobalt alloy porcelain crown, gold-platinum alloy porcelain crown and gold deposition porcelain crown.

1) Nichrome porcelain crown: The inner crown is made of the base metal nickel-chromium alloy, in the complex oral environment, the metal part exposed to the oral cavity will slowly decompose, and release black oxide, resulting in local tissue staining, which is the most important reason why this kind of restoration will cause black lines on the gums.

2) Titanium cobalt alloy porcelain crown, gold platinum alloy porcelain crown and gold deposition porcelain crown: collectively known as *** porcelain crown, the inner crown is titanium cobalt alloy, gold platinum alloy, electroplating pure gold, they are all inert metals, the probability of allergies is small, and the physical and chemical properties are very stable. It is worth mentioning that the color of the inner crown of gold-platinum alloy and gold deposition is similar to that of dentin, so the aesthetic effect of the restoration is better than that of titanium alloy porcelain crown. However, due to the small specific gravity of titanium itself, the weight of titanium alloy porcelain crown is obviously lighter, which is suitable for multi-unit porcelain bridge restoration of posterior teeth.

Generally, about 65% of all-ceramic teeth can be used for more than 20 years, but this has to vary from person to person.

In order to use all-ceramic teeth for a longer period of time, post-operative care is also very important. After the operation, you should eat as slowly as possible, and you should not eat too hard food after the operation, and you should usually bend the air after making all-ceramic teeth to maintain oral hygiene, and regularly return to the noise to do dental cleaning.

The service life of all-ceramic teeth is related to many factors, in order to make the service life of all-ceramic teeth longer, postoperative maintenance is also very important, on the one hand, diet and the other is daily health care.

Many people need dentures to maintain normal chewing due to tooth loss, or some kind of tooth problem, and porcelain teeth are a good choice, but the problem is that there are many types of porcelain teeth, for choice phobia, there is no choice at all, and I don't know what is the difference between porcelain teeth and all-ceramic teeth, and I don't know how to choose? So let's tell you the difference between the two, you can choose according to your own situation?

1. The types of raw materials are different

Porcelain teeth: cast metal is used as the core of support, including nickel-chromium alloy, titanium alloy, gold-platinum alloy, etc.

All-ceramic teeth: with special, high-strength alumina or zirconia ceramic materials as the core, it is a non-metallic material.

2. The degree of crack resistance is different

Porcelain teeth: The core is a metal material, which is harder than enamel and all-ceramic teeth, and the degree of crack resistance is also better than that of all-ceramic teeth.

All-ceramic teeth: non-metallic materials with a core, the hardness is softer than porcelain teeth, harder than enamel, and the degree of crack resistance is inferior to porcelain teeth.

3. The aesthetics of teeth are different

Porcelain teeth: 1. Factors such as the crown of the metal base layer, the thickness of the porcelain layer, the condition and frequency of the barbecue teeth, the colorant, the surface texture, and the light source will affect the color.

2. The metal oxidizes into gray oxide in the oral cavity and precipitates on the edge of the gums, causing gums and graying.

3. To cover the color of the metal core, it is necessary to use the covering porcelain layer, so that the sense of hierarchy and realism of the teeth is poor.

All-ceramic teeth: contain colors and provide a standard color palette, will not change color with the above factors, and have good refractive and transparent properties, and have better tooth aesthetics.

4. Different from tissue compatibility

Porcelain teeth: There is a metal core, which has poor compatibility, which may lead to metal allergies and swollen gums, bleeding and other conditions.

All-ceramic teeth: good compatibility, insoluble in saliva and other acidic and alkaline substances, allergies are rare.

5. Applicable groups of people are different

Porcelain teeth: suitable for the toothless parts of the oral cavity, the alveolar bone bone is sufficient, and the gap between the upper and lower teeth should not be less than centimeters when occlusing, which is mostly used for high-strength fixed restorations such as dental fixed bridges.

All-ceramic teeth: suitable for individual premolars, single crown of anterior teeth, ingrown teeth, high inlay teeth and veneer restoration, which requires a good occlusal relationship.

6. **Different

Porcelain teeth: the equipment requirements are simple, the cost is low, and it requires hundreds to tens of thousands.

All-ceramic teeth: The production of all-ceramic teeth requires special equipment and special training personnel to operate, and the cost is high, ranging from 10,000 to 100,000 pieces.

7. Precautions

1) It may be mild and uncomfortable at the beginning of wearing, because the alignment of the upper and lower teeth may change, chew slowly and gradually adapt, so as not to bite the buccal and tongue mucosa.

2) Do not use porcelain teeth to bite too hard and tough food, such as melon seeds, walnuts containing potato socks, bones, sugarcane, etc., otherwise the porcelain may collapse.

3) Pay attention to keep your hands clean and your mouth clean, brush your teeth twice a day, use dental floss to clean between your teeth after meals, and go to the hospital regularly for check-ups and cleaning.

4) After wearing porcelain teeth, if the phenomenon of cold and heat sensitivity, pain and other phenomena continues or even worsens, it is necessary to seek medical attention in time.
