zirconia all-ceramic dental Scope fine list

 Zirconia all-ceramic dental restoration is porcelain teeth in an excellent view of zirconia all-ceramic dental advantages, many of my friends want to do U.S. dental zirconia all-ceramic dental

. But as a means of repair, ultrasonic scaler zirconia all-ceramic dental also has strict scope, then zirconia all-ceramic dental scope, what does?


        Zirconia is a high temperature, wear-resistant, corrosion-resistant inorganic non-metallic materials. Its melting point up to 2700 degrees Celsius, the best performance is the nature of fire

One of the materials. Its thermal conductivity is poor, but the conductivity is very strong, strong ability to resist, even if heated to over 1900 degrees Celsius will not work with molten aluminum, iron, nickel

, Platinum and other metals, dental tools silicates, and play a role in acidic slag. His toughness is much larger than other known non-metallic porcelain.


        About zirconia all-ceramic dental scope, experts pointed out include the following aspects:


        Discolored teeth, common yellow teeth, perfect repair tetracycline, correcting individual missing teeth, broken teeth, teeth too wide, enamel hypoplasia, malformations and other types of teeth

Branch diseases can be used zirconia all-ceramic dental.


        In addition, zirconia all-ceramic dental appearance, the perfect solution to patients with severe tetracycline teeth beauty needs; zirconia all-ceramic dental because most prominent feature is not

Metal within the crown, so the teeth, dental chair good transparency, excellent gloss, more effective way to avoid metal allergies and other problems. In addition, he has a good enough masking capabilities, superior toughness so

No matter how your teeth are no worries; zirconia all-ceramic dental appearance and vivid color, strong wear resistance, good biocompatibility, does not stimulate the oral mucosa, easy to clean.

the production of all-ceramic dental materials which have

Yes called all-ceramic dental cosmetic teeth in the classic, is the darling of many stars beautiful teeth. Naturally, this high-tech all-ceramic dental porcelain teeth, its price is not cheap.

Investigate its reason lies in the expensive all-ceramic dental materials. The material determines the price of porcelain teeth. So all-ceramic dental materials are what it?


        About all-ceramic dental ultrasonic scaler materials, experts say, all-ceramic dental materials are distributed such, the outermost layer of high-temperature ceramics for the space shuttle, the inner layer is

Thermal expansion synchronized gold tooth sets, porcelain teeth are many steps of the production process, is set high, casting, bonding technologies such as high-tech products.


        As cosmetic dentistry in the dental chair classic, all-ceramic dental lifelike appearance beautiful, rugged wear, mimicking the natural color of teeth, biocompatibility, do not stimulate the oral group

Weaving, easy to clean, that is able to restore the function of the teeth, but also the role of beauty. This is due to all-ceramic dental materials Reflected.


        All-ceramic dental materials, dental tools with its production are closely related. First, you want to grind my teeth cone-shaped (when necessary go pulp), casting an alloy jacket crown (called crown

Nuclear), on top of this will bring good color deposited on a ceramic tooth shape carved dresser, put sintering furnace, wearing abutments.

dental machine status abroad

dental machine operating principles

The punch and die during tableting by the pressure, common bearing steel (such as crl5 etc.) production, and

heat-treated to increase its hardness.

Many types of punch, punch tablet shape determined by the desired shape. Press the structure and shape of the

die can be divided into round, shaped (including polygonal and curved);

Punch the shape of a flat-shaped resin teeth cross-section, bevel-shaped, shallow concave, deep concave and integrated

shape. Flat-shaped, bevel-shaped punch for pressing flat cylinder-shaped tablets,

Shallow concave biconvex tablets for pressing, deep concave mainly for press-coated tablets of the chip,

integrated shape mainly used to suppress shaped plate-shaped. In order to facilitate the identification and

services

Used drugs in the end face of the die can also be engraved the name of the drug, dosage and vertical and

horizontal lines and other signs. Suppression of different doses of tablets, you should select the

appropriate size of the die

.

(2) tablet press tablet press dental supply companies working process of the work process can be divided into the following steps:

① undershoot punch position (its working position facing up) into the Central die hole in the bottom die

hole, seal the hole bottom mold;

② The Araliaceae is to fill in the hole in the mold drugs;

③ punch on the red parts (its working position down) from the falling upper die hole in the die hole and

down a certain stroke, the powder into tablets;

④ ascend out of the hole punch, punch up the tablets under the top of the hole in the mold, to complete a

tabletting process;

⑤ undershoot down in place, ready for the next fill.

(3) tablet tablets principle mechanism

① dose control. Tablets have various requirements of different doses, the large dose regulation is

accomplished by choosing different diameters of the punch die to be achieved, if the diameter 6mm

, 8mm, 11.5mm, 12mm, etc. punch. Die size is selected, the tiny dosage adjustment by adjusting the lower

punch inserted into the depth of the hole in the mold, thus changing the back cover

After the actual length of the die hole, adjust the die hole filling volume of the drug. Therefore, in the

tableting machine should have under the Diamond Burs regulation of the die hole punch in the original location of the

institution,

Dose adjustment in order to meet requirements. Because different batches of powder preparation total

hematocrit differences, this regulation is necessary.

At a dose control, the operation principle of the feeder also has considerable effects, such drugs are by

weight of particulate, free-rolled into the die hole, its loading condition

More loose. If using multiple compulsive way into the environment, the die hole will be filled with more

drugs, filling the situation is more dense.

② tablet thickness and compaction control. The dose is determined according to pharmacopoeia prescription

and can not be changed. For storage, preservation and disintegration time requirements,

Tabletting pressure of a dose is dental instruments also a requirement, it will influence the actual thickness and appearance of

the tablet. Tableting pressure regulation is essential. This is done by

Adjusting the upper punch holes in the mold downlink capacity to achieve. Some compression tableting machine

during operation only on the red down, but also to act as a lower washed by

Relative motion upper and lower punches together to complete the tabletting process. But mostly by adjusting

the pressure regulator on the red down the amount of pressure regulating agencies to implement and control.

long-term unexplained toothache Please note cracked teeth

Long-term unexplained toothache may be provided by cracked teeth caused because crack cracked tooth dentin structure constant depth, while the non-physiological crown surface hairline cracks often difficult to detect and is ignored, so long as the reasons found unknown toothache, clinicians should be given adequate attention, check for cracked teeth.
Cracked teeth occurred in the maxillary molars most mandibular molars and maxillary second premolar; significantly more than the first molar second molar, mesial palatal tip (ie, bear the greatest work of occlusal force tip) more likely. Teeth withstand stress concentration occlusal force itself cracking strength is low, cusp inclination large force trauma teeth are cracked teeth fracturing factor.
If the elderly molars dental steam Sterilizer and bicuspids for a longer time chewing pain and cold pain, irritability history, or bite causes pain in a particular area, and there was a history of injury Ge hard objects that may occur teeth hidden crack. Characterized as follows: occlusal surface cracked coincide with developmental groove and extends over the edge of the ridge; cracked iodine can be stained or radiographic examination see the shadow of deep fine tooth body with the same name as the teeth often symmetrical jaw occurred; suffering occlusal abnormal wear and face steep cusp, there are side percussion pain and biting pain clinics; often cracked at pigmentation, secondary pulp hyperemia, pulpitis, pulp necrosis and periapical inflammation.
For superficial cracked, no obvious symptoms, pulp vitality normal for occlusal adjustment therapy, can also be prepared hole, rubbed crack for preventive filling; For deep cracks or endodontic lesions, in endodontic treatment, while a large number of adjustments cusp slope, completely remove the teeth are exposed fracturing force, dental machine after treatment in a timely manner crowns; endodontic treatment started to do with ring glue to protect the crowns, endodontic treatment should be finished in time for the full crown restoration is essential.

what is the cavities

1 What is the formation of cavities?
   There are four conditions for occurrence of dental caries: bacteria, food, teeth, time. Under normal circumstances, the people of the many oral bacteria, there is a acid-producing bacterium which is also known as cariogenic mutans bacteria. When the food residues present in the surface of the teeth for a long time, cariogenic bacteria and food carbohydrates will react to produce acid, these acids react with the enamel, making demineralized enamel surface, softening, disintegration, forming shallow cavities, then the general feeling no pain, not easily found. dental supply companies If this time is not treated, cavities will grow larger and more deep, superficial damage to the dentin, then eat hot and sour spicy food, the teeth will feel sore. If you still ignore and undermine the pulp, causing pulpitis, there will be a spontaneous severe pain.
2 teeth with holes is not to wait for the pain to fix?
    Not. The teeth have holes to fill in time, you should not wait until the pain to fix. Once a toothache, you need to kill the nerve to do root canal treatment, so that not only the treatment of complex, and the cost to increase, more harm than good. So to the problem in the bud, put it to get rid of, do not wait complexity of the problem, and then solved.
3 teeth hurt too nervous to kill you?
    Depending on the circumstances. Teeth hurt does not mean there is no problem nerves, according to the doctor checks to determine the state of the pulp symptomatic treatment. In general, the pulp is infected, you need to remove the pulp (ie kill nerve) is more likely.
4 teeth have holes, why was it not hurt?
    The outermost layer is called dental enamel, which is no distribution of nerve endings. When cavities located on this floor, people generally do not feel pain. Enamel called dentin layer below, and its distribution within the nerve endings, so it is sentient. Development of this period will not be spontaneous cavities usually pain, but encountered cold, hot, sour, sweet pain can occur when stimulated, more obvious when cold, when the food embedded into cavities also occurs pain. If cavities deeper cause chronic pulpitis or pulp necrosis and chronic periapical, the teeth but not too painful.
5 How to prevent cavities produced?
    First, develop dental handpiece good oral hygiene habits is the most important. Brush your teeth after a meal before going to bed, to develop the habit of flossing, thus removing the food this cariogenic conditions. Secondly, the use of fluoride toothpaste for teeth. Fluoride and calcium binding in the tooth can enhance the ability of acid-resistant teeth. Third, there are some teeth, structural defects, such as deep fissure. Sealant can be prevented. Another irregular teeth can easily lead to clean difficult, orthodontics can solve this problem.

new growth two front teeth do not rely rope how to do

3 new growth two front teeth do not rely rope how to do?
New growth two front teeth do not rely rope how to do? New growth often appear dentition maxillary two gates (incisors) teeth between the large joints, can not move closer. Parents do this very anxious. It can be divided into two situations: one is temporary and normal phenomenon in early mixed dentition, the gap with both sides of the lateral dental Composite incisor and canine eruption will gradually disappear; Another situation is caused by pathological factors, such as: two incisor teeth big ambush between multiple teeth exist, the gap between the front teeth does not go away, should go to the doctor immediately. Therefore, when the two front teeth delays closer, they should seek help children dentist checks, such as abnormal, need early treatment.
