Is there a laser instrument that can measure the fit of porcelain teeth in three dimensions? 20

yes. I'm selling this product right now! CONO series laser probes. Here are their parameters.

CONO series parameters:

Scan head mass (g) 700

Electrical control box mass (g) 1200

Scan sampling speed 850 points per second (pps).

Macros Macros automatically provide suitability measurements.

Output data format: Excel AscllText File Bmp, JPEG, UBM, VRML

Apply. Measurement accuracy is related to the accuracy of the lens.

The angular measurement range is 0 170 degrees.

Ambient temperature 18-35 degrees.

Supply voltage: 82 265 volts AC 50-60 Hz.

Students majoring in surveying must have the following basic skills in order to work. In terms of measuring instruments, the first thing to do is to use a total station, now the more popular is the domestic southern total station, learning to use the southern total station is very beneficial, because the southern total station and the imported Topcon total station is almost the same; The second is to be proficient in the use of levels; The third is to learn to use GPS, GPS is the trend of future measurement, which is very convenient.

In terms of drawing software, the basic skill is CAD, and then learn the southern CASS measurement and mapping software after learning CAD, and now the measurement and drawing are digital, and it is very convenient to use the southern CASS software to make a drawing.

This kind of device is called directional pickup, or super directional pickup, it can pick up sound dozens of meters away from the sound source, bird observation is also often used this kind of equipment, it has three structural types, barrel type, array type and focused type. The best ones can pick up sound from 100 meters away, but they won't work properly if there are obstacles.

Yes, it's suitable for a younger age.

Hello, you are in this situation:1

The best case is dental implants, which are just 2 of the 6 teeth that have been lost in the front, and then the teeth are prosthetic. 2.

Then you can only do movable teeth, the second plan you said is completely unnecessary, it is to cheat you out of money, other things such as fixed bridges, all porcelain and so on are not suitable for you.

This kind of porcelain tooth is available. In order to reduce the grinding of teeth and have sufficient strength, some doctors will make it metal in places that do not affect the appearance (generally speaking, the teeth that need to be ground out are about 2mm if the occlusal surface is porcelain, and metal is enough).

But I'm sorry to tell you that nickel-chromium alloy porcelain teeth have been eliminated products, and its harm lies in the fact that under the action of saliva, nickel-chromium metal ions will precipitate and appear a black line on the edge of the gums, which will affect the appearance, of course, the precipitated metal ions will be harmful to the human body if they enter the blood. Now there is a porcelain crown of this alloy is mainly for patients who cannot afford a good porcelain crown but need to be repaired, and often in the back teeth, there will not be too much impact on the appearance, which is called the lesser of the two phases. Therefore, we usually recommend that patients choose at least half of the porcelain crown of the anterior teeth.

After a long time, it must be bad, if your teeth are the front teeth, you can do all-porcelain teeth, and the inner and outer crowns of all-ceramic teeth are porcelain, so there is no problem of metal corrosion.

It depends on the condition of your own mouth, if your oral condition is very allergic to metal, then you have to change it immediately, if you feel no discomfort now, then you don't have to care. It is recommended that you go to the Department of Stomatology of Pengcheng Hospital for consultation, where the dentistry is good.

Hello, porcelain crowns, generally after repairing a good time, it can be adjusted for cementing, and it is rarely repaired repeatedly

It is normal for porcelain teeth to be different in color from normal teeth under different lights, after all, it is not a substance. However, pus in the gums is not normal and will most likely need to be redone.

Radars that operate in the infrared and visible wavelengths are called lidar. Three-dimensional laser scanning technology, also known as real-world replication technology, is an instrument that scans and obtains the three-dimensional coordinates and reflected light intensity of the surface of the measured object by emitting a laser, and is a non-contact active measurement system.
