"It's too much trouble to run a tooth and run the hospital many times." This is a common concern for many patients suffering from oral diseases. Now running a hospital, you can complete the mold, make, debug, and install your teeth. This is the 3D printing tooth technology.
The reporter learned from the Department of Oral Prevention of the First Affiliated Hospital yesterday that since the hospital started 3D printing of dental technology in provincial public hospitals since December last year, hundreds of Yunnan patients have placed 3D printed teeth.
Mr. Yu, 50 years old, at the age of 18, the two front teeth were cut off by hard objects. After that, the inflammation and pain were dropped. After being treated more than ten years ago, the teeth are not inflamed or painful. However, as time went by, the two front teeth began to turn black and always felt unattractive.
In order to save time and save trouble, Mr. Yu chose to install two 3D printed all-ceramic teeth. The Department of Oral Prevention of the First Affiliated Hospital made a pair of all-ceramic incisors for Mr. Yu, so that Mr. Yu only ran once in the hospital and put all the problems. solved.
Yesterday afternoon, the reporter saw this set of 3D printing equipment: a computer and a 3D printer . A computer-connected scanner is the key to getting patient dental data. Before making a model for Mr. Yu, the doctor extended the scanner into Mr. Yu's mouth, scanned the upper and lower teeth, and then scanned the teeth twice and in the occlusal state. During the scanning process, relaxed music was also played. According to reports, music is to relieve the patient's emotions. If some scans are incomplete or incorrect during the scanning process, the machine will make another sound.
After the scan is completed, Mr. Yu’s tooth shape has appeared on the computer simultaneously. According to the shape of the patient's teeth simulated by the computer, the doctor makes a model through computer 3D technology, and then can officially enter the 3D printing process.
After the doctor puts a piece of porcelain into the printer, the three drill bits on the printer grind the porcelain block at the same time until the ceramic block is ground into the designed shape. Printing two incisors with a 3D printer takes just over 10 minutes and the accuracy of the teeth is higher. During the installation process, according to the actual situation and patient comfort, minor manual trimming can be carried out to load the teeth into the patient's mouth. In addition to one-to-one tailor-made teeth for patients, color can also be based on the patient's individual teeth, choose the most suitable color of the patient's teeth, to avoid color aberrations with the real teeth.
Silica gel relative to the ceramic tableware, plastic tableware, hardware, silica gel tableware harmony together with temperature, in which food is cold is hot, can protect the temperature of the food itself, reduce the loss of the change of temperature and a period of time in the silicone bowl or pot food can still maintain the original temperature, when use won't convey the temperature of the corresponding to the user. Moreover, the particularity of the silicone material itself, which is different from other materials, makes the products produced by it have an amazing effect. For example, landing silent food containers, after high temperature cooking, will not produce harmful substances. And tableware but fold, can knead, can turn over, chuai also does not take a space in the pocket, also won't adsorb smeary. Its own desiccant effect, will not because of long-term storage and moldy, qualitative change.
And because of silica gel temperature resistant properties, heat resistance of 240 ℃ high temperature deformation, won't produce hardening phenomenon to 40 ℃, so the product is fully staffed, very practical, we don't have to classification of casual in a microwave, don't worry about the melting and aging and yellowing phenomenon, and it is easy washing, can use less or even do not use detergent containing chemical substances, practicability and convenience are very strong, very suitable for use in their life.
