all-ceramic dental advantages are what it

Teeth as compiled shell" is the desire of many beautiful people beauty. Past metal porcelain teeth in the oral medical esthetic techniques boarded a another peak. And now begins

All-ceramic dental era, appeared it ultrasonic scaler won the "best U.S. dental" praise. In the end all-ceramic dental advantages, what does?


        First of all, all-ceramic dental comparable to natural teeth color can be used with: porcelain teeth each tooth through CAD / CAM tailored, no metal smell, its hierarchy, color and most

Close to real teeth. This is also one of the most emphasis on the consumer all-ceramic dental benefits.


        Secondly, all-ceramic dental tools  personalized esthetic effect is excellent: on all-ceramic dental aesthetic effect is concerned, it is almost perfect. The technology has a dozen colors to choose from,

And color stability, providing natural beauty, rich in active repair effect, and can be based on each patient's own esthetic conditions and needs to choose, to personalize America

Tooth best results. This is also the favorite of many a fashion trend of people all-ceramic dental benefits.


        Finally, safe and reliable all-ceramic dental pulp does not hurt: all-ceramic dental thermal conductivity is very low, only gold seventeenth, more conducive to the protection of the pulp, the quality of light

, Only a quarter of the gold, the dental chair patient more comfortable to wear. Porcelain teeth have been the world's more than 1.5 million dental patients lifted dental troubles, vivid colors make it

Over the last few years, people of European beauty choice.

all-ceramic dental shortcomings

So far, the most all-ceramic dental aesthetic effect is a dental prosthesis, hard, wear-resistant, high compressive strength, appearance naturally pure, crystal clear, color force

True, close to the natural teeth. All-ceramic dental biggest feature is no metal! So, all-ceramic dental shortcomings, what does?


     All-ceramic dental drawback is ultrasonic scaler relatively small, mainly in the following two ways:


     Shortcomings of an all-ceramic dental: all-ceramic dental expensive. This is the all-ceramic tooth on the market a big problem, many patients can not afford the fees. If you do all-ceramic dental restoration

Surgery, the first thing to consider is whether to allow their economic conditions, of course, in the choice of porcelain teeth, they also can not blindly pursue the most expensive porcelain teeth, because the material

Different, preferably under the dental tools guidance of professional doctors choose their own material.


     2 all-ceramic dental drawback: all-ceramic dental may cause allergic symptoms. Resin-reinforced cement due to the need to enhance strength, and found clinical applications in dentistry, and the

Compared with the complex plasma, using reinforced cement can cause allergies occur after the repair, but this dental chair incidence is very low. Consumers can check the body

See that he is not allergic, so as to effectively prevent the allergy.

dental machine history

Tablet press tablet press appeared in Europe earlier, there are nearly a hundred years of history. In China

in 1949, Shanghai Tianxiang Hua Kee Iron Works imitation caused British 33

Punch tablet press; 1951, dental x ray according to the U.S. 16-punch tablet machine converted into a domestic 18-punch

tablet machine, which is the earliest domestic manufacturing pharmaceutical machinery; 1957, designed and

manufactured

ZP25-4 type tableting machine; 1960, to design and manufacture successful 60-30 type tableting machine, with

automatic rotation, compression function, pressed varieties tablets, sugar tablets,

Calcium, coffee tablets. The same year also design and manufacture a type ZP33, ZP19 type tabletting machine.

In the 1970s began Shanghai Daiichi Pharmaceutical Machinery Factory (Shanghai Tianxiang's predecessor) and

Shandong Medical Instrument as compression tableting machine tablet press sentinel manufacturers large

Production ZP series tablet press. "Plan" period, the Department of Aerospace 206 HZP26 successfully

developed high-speed tablet presses. In 1980, the Shanghai Pharmaceutical Machinery Factory first system

designed to

Made the ZP-21W type tableting machine, to the early 1980s the international advanced level, is the first

domestic product. 1987, the introduction of the Federal German Fette company microcomputer control

Manufacturing technology, design and manufacture of P3100-37 rotary tablet press with automatic control

tablet weight, pressure, automatic digital film, films and other features automatic elimination of waste,

closed

Structured, the degree of purification to GMP requirements. 1997, the annual Shanghai Pharmaceutical

Machinery Co., Ltd. Tianxiang Kin developed ZP100 series rotary tablet press, GZPK100 Department

Column speed rotary tablet press.

In the 21st century, with the deepening of GMP certification, in full compliance with the GMP ZP series

rotary tablet machine have appeared: Shanghai's ZP35A, Shandong Liaocheng ZP35D

And so on. High-speed rotary tablet machine production, the pressure signal acquisition and rejection and

other technology has been developed rapidly, the highest yield is generally greater than 300,000 / hour, the

most

Large pre-pressure 20kN, 100kN maximum principal stress 80kN or more. For example, the Beijing Science and

Technology Co., Ltd. Sinopharm Long Li GZPLS-620 Series High Speed ​​Rotary Tablet Press,

Shanghai Tianxiang Jian Pharmaceutical Machinery Co. GZPK3000 series high speed rotary tablet press, Beijing

Aeronautical Manufacturing Technology Research Institute, PG50 Series High Speed ​​Rotary

Sheet machine.

With the level of manufacturing process dental supply companies technology, automatic control technology to improve and tableting

machine manufacturers use a variety of special needs, a variety of special-purpose tablet press

Have also emerged. For example, laboratory ZP5 rotary tablet machine for dry powder tabletting rotary tablet

press machine for gunpowder explosion-proof ZPYG51 series tablet

Rotary tablet machine.

dental machine development status of domestic

(1) tablet machine specifications numerous large quantities. Tableting machine, although the oldest of

pharmaceutical production equipment, as well as export the earliest, the largest pharmaceutical production

equipment

. Can suppress round tablets, dental x ray engraved tablets, shaped tablets, double-layer tablets, multilayer tablets,

ring-shaped piece, including chips and other sheet-type. Tableting machine manufacturer's number, types and

specifications, production

In the world, is an indisputable fact.

(2) easy to operate. In recent years tableting machine manufacturing companies starting to focus on quality

of products, mostly Bong letter "quality win" business philosophy. For the domestic pharmaceutical

manufacturers

Many tablets resin teeth variety, small-scale production features. Tableting machine manufacturing enterprises, the

development of tableting machine with a simple, clean convenient features, special

Do not be replaced varieties, cleared quickly and easily.

(3) low-tech, technological innovation after the weak. More than 40 domestic pharmaceutical production

equipment more than sixty varieties and specifications tableting machine tableting machine. Although,

Every year new products are constantly introduced. But where the real level of technology and high added

value of the species are few. Product duplication of development serious plagiarism

Prevalence of a variety of tablet presses up to dozens of manufacturers. To survive, many small-scale

pharmaceutical equipment enterprises not only in technological innovation to take "Imitation

"Strategy, some manufacturers even entirely by copying someone else's technology as their technology"

To take measures to keep the prices down, because brand loyalty is low, the price war playing, these brands

more disadvantage, will inevitably lead to the design and manufacture of tablet presses down the overall

level of

Retreat.

Vast majority of China's enterprises are private enterprises in technology, equipment, personnel and other

aspects not have the advantage, seriously restricting the technological innovation of enterprises. Section

Lack of corporate R & D institutions, innovation system is not perfect, the lack of technical innovation and

technical personnel, their overall dental supply companies technical strength is not strong, updated technology and equipment

research and production speed

Degree is very slow. The most noteworthy is that the entire industry technology professionals are in a "lean"

stage. It can be said, is the entire industry talent crisis

How long can mend teeth

We know that the teeth rotten hole on the back as soon as possible to the hospital for treatment (fillings). Dental health supplement can be used exactly how long, this is the most concerned about the patient, but also a more complicated issue. Teeth dental chair repaired after a short period, and how the function, with a variety of factors. The first is timing fillings, ie when the patient visits the extent of dental caries. Location and shape of cavities have a great relationship. Followed by the filling materials, different materials and the bond of cavities vary. Furthermore, that dental cavities before processing. If only carious cavities and the cavity is good, shallow, and not adjacent surfaces of teeth, etc., are only required to clean and remove tooth decay cave organize, prepare cavity, thorough disinfection, with permanent dental materials the cavities were filled. Such a good complement of teeth should be used for life. When the dental pulp or apical lesions reached, as long as thoroughly anti-inflammatory treatment, and finally achieve tight filling, but also can be lifelong. But if severely dental drill damaged teeth, tooth hole is too large, too deep, irregular shape, or proximal hole type, then filled with good teeth should be used with caution. Otherwise, biting hard objects prone to splitting or dental fillings fall off. Especially kills nerve or pulp necrosis teeth without a blood supply, the teeth become brittle, so anti-inflammatory teeth after filling, biting hard objects it more likely to cause tooth splitting, filling off, resulting filling failure; even teeth completely split split into the following gums, often leading to tooth extraction. Thus, the success of the dental patient and doctor relationship between the two are very closely related. First, the doctor fillings should be strictly and carefully press the formal procedures to operate, and the patient dental machine should also be early detection and early dental treatment, filling a good fight in the early carious teeth, to achieve the best results.

toothache types and treatment

As the saying goes: "toothache is not a disease, pain up to life," there are many manifestations toothache
1, hot and cold sweet and sour pain: sweet tooth pain cold case, removal of irritants, the pain disappeared. Dental pigmentation, common to dental caries. Gingival margin tooth surface, no pigmentation, deep wedge-shaped defect. Two kinds of dental problems are mild, restorative treatment can improve. But if it is due to gingival recession caused by dentin hypersensitivity, the treatment process is more complicated.
2, spontaneous pain: spontaneous gingival pain, can not be located, the pain got worse when sleeping; cold, heat dental unit price stimulation can induce pain, remove the pain stimulus continues for some time, pain to the ear temporal radiation, which means that there is inflammation of the pulp.
3, persistent pain: persistent pain in the gums, can be clearly positioned teeth floating sensation, knocking teeth or bite things obvious pain. Description invade apical inflammation. Treatment is too much trouble, emergency principle is "decompression and drainage" - to open a hole in the middle of the tooth, so inflammatory secretions out, reducing the pressure of the pulp cavity. X-rays taken after the election according to the condition of root canal treatment or plasticizing treatment.
4, biting hard objects pain: dental machine pain biting hard things have knock history of stones and other hard objects. Tooth may have cracks, severe tooth may crack. Depending on the depth of treatment decisions cracked: If tooth is loose, you want to unplug. Such as shallow, you can do sets crown retained.
5, "best-rooted teeth" pain: do-rooted teeth (wisdom tooth, third molar) at the persistent pain, touch gum pain got worse, with severe mouth ox, often made inflammation, anti-inflammatory after the removal of "best-rooted teeth." .
6, gum pain: persistent pain in the teeth, accompanied by swelling, loose, many accompanied by food impaction symptoms of periodontitis performance.
 
  These symptoms should be dental chair treated early, while painkillers to ease the pain.
