What is the difference between the use of oral cemented powder filler and amalgam filler?

Well, yes, the cement powder filler is only used for the filling of glass ions and zinc phosphate, and there are some backing materials, such as zinc oxide, calcium hydroxide, etc.

Amalgam filler due to the different shape and structure, if you use it to fill glass ions or something, it is very inconvenient to use, and there are special light-curing resin fillers, the structure is different, of course, the use is not the same, with the right tools, you will get twice the result with half the effort.

Let's say, for example, tooth extraction forceps, if you use the right forceps for this tooth, you save time and effort, and what would you feel if you used something else?

Oh, in a sentence in our Henan, it is that the guy is energetic, and the work he does is called beautiful!

The working surface of the cemented powder filler is smooth and clean, and the surface of the filled filler is smooth; The working surface of the amalgam filler is patterned for easy extrusion. It's not the same tool, so don't mix them up.

There are many small protrusions at the end of the amalgam filler, which is convenient to squeeze out the excess mercury when pressing the material, and the surface should be smoothed with a polisher after filling; The end of the filling of the cement powder filler is flat, and the filling of zinc oxide, zinc phosphate, glass ions, light-curing resins, etc. can be used, and amalgam is not applicable.

Ha ha! It's a peer.,But your 10 points are too difficult to answer.,There's a lot of things in stomatology.,And new things are constantly increasing.,I still don't know a lot of things.。 Stomatology is divided into internal medicine, surgery, orthodontics, implants, etc., and the instruments are divided into categories, which is not clear at once.

The most basic is the instrument curved plate, which contains an oral mirror, tweezers, and a probe to check the oral condition. Internal Medicine: DG16, Root Canal Ruler, H File K File Enlargement Needle, Side Pressure Needle, ET40D, Swing Washing Needle, Rubber Dam, Cleaning Table, Root Canal Lubricant, Vertical Pressurizer, Teether Cutter, Hot Teether Filler, Machine Expansion, Root Canal Microscope, etc.

Surgery is a variety of dental forceps, you can search the picture on the Internet. Orthodontics: needle holders, end cutters, filament cutters, filament pliers, collars with rings, square wire cutters, lid openers, bracket forceps, flat-tip pliers, three-pronged pliers, three-pronged pliers, wire cutters, trapezoidal pliers, etc.

Ordinary instruments: digging spoons of each size...Fillers (different names vary from place to place), wax knives, wax spoons, trays, etc.

Ah, many, many, let's learn together!

Buy a basic book on oral surgery. There is an introduction to the equipment and equipment.

3. All digging spoons: composed of a handle and two working ends, the working end is a spoon shape, and there are three types of large, medium and small. Scooping spoons have the purpose of scraping off humus and inflammatory tissues, cutting the marrow, and removing temporary seals.

Adhesive filler: one end is flat and blunt, which is used to take the paste and can be used to fill the adjacent surface hole of the posterior teeth; At the other end is a smooth surface filler, which is used to fill the paste.

Milk bowls and pestles: used to prepare amalgam by hand.

Amalgam mixer: used for the preparation of amalgam capsules.

Amalgam engraver: The working end is oval or small round and bifurcated, and is used to engrave the shape of the amalgam. Note: The angle and smooth edges of the working end of the engraver should be maintained.

Amalgam conveyor: consists of a push handle, a conveyor sleeve bent at an angle, and a spring bolt. The modulated amalgam is placed in the mouth of the sleeve and the spring plug head is compressed by the push handle to push the amalgam into the cavity to be filled.

Amalgam filler: used to fill amalgam.

Amalgam polisher: the working end is spherical or pear-shaped, with a smooth surface, which is used for the dressing of the amalgam filler after filling, and the smooth surface makes the edge of the filler fit with the cave wall.

There is no need to apply for a medical device business license.

If the tooth is not treated properly, it will also cause adverse consequences such as loss of the filling, cracking, etc., so the attention after the filling should not be ignored.

After the amalgam filling, grinding, blending amalgam is soft and plastic, easy to fill, carve the appearance, 10 minutes after the gradual hardening, 24 hours after the complete hardening, therefore, within 24 hours can not use the tooth to bite the object, let alone bite the hard object, otherwise, the bite filling, resulting in filling failure.

After tooth-colored material filling, within a few days after filling the tooth with composite resin material, try to drink less coffee, strong tea, smoke less, and eat less dark-pigmented food, such as soy sauce, black vinegar, etc. So as not to color the feed and affect the appearance.

Non-metallic materials such as composite resin and cemented powder only reach about 80 after the doctor fills it, and it can be completely solidified after 24 hours. Therefore, after using these materials for fillings, you can eat softer foods first, and then apply them normally after 24 hours. If the anterior tooth is filled with a large defect, it is necessary to be careful when biting the food to prolong its use.

Amalgam is a metal material, which is ground into a paste before filling, which is plastic, and can not eat any food within 2 hours in the cavity of the filler, and cannot chew food with the tooth within 24 hours, so as not to cause the filling material to deform, break or fall off. After the tooth is complex**, due to the loss of some nutrients**, the tooth will gradually become brittle. Therefore, although the tooth can return to normal chewing function after filling, it is necessary to be careful when biting into food with hard shells to avoid causing cracks in the tooth wall.
