Analyze what changes 3D printing has brought to correct teeth

Anecdote happened not long ago: NASA is studying to allow astronauts to make pizzas in space using 3D printers. Perhaps this anecdote has a lot of jokes, but there is no doubt that people are no stranger to 3D printing technology. Compared with the "games" of printing common items such as parts, toys, handicrafts, etc., 3D printing technology is now steadily entering the medical field, which has revolutionized medical methods.

The nuances of each person's body are different. Therefore, traditional medical methods are difficult to tailor treatment for each patient. The inherent advantages of 3D printing, such as personalization, small batch size and high precision, solve this problem and bring patients far more traditional treatment effects and experiences. If there is still a long distance between the printing of blood vessels and bones, then the invisible braces mentioned below are products that are currently based on 3D printing technology for large-scale applications.

Traditional orthodontic methods use brackets and steel wires, which are commonly known as "wire braces". Unsightly, limited diet, difficult to clean, easy to grind the mouth is its biggest slot, the experience brought by this wire braces is more like a torture. The bigger problem is that the traditional orthodontic process relies too much on the individual's personal experience. When the doctor sticks the groove and bends the wire for the corrector, the thickness, strength and curvature are controlled by the doctor by hand. To this end, the medical research team has developed a new type of invisible correction braces based on 3D printing technology, hoping to solve the problems of traditional orthodontics.

Beauty is a dental invisible correction direct operation organization, and it is also the only oral intelligent medical beauty brand in China that completes all aspects of research and development, production, sales and treatment. The author learned more about the principle and practical application of this 3D printing product from the beauty orthodontic doctor.

First, the orthodontist will use silicone rubber to extract the dental mold for the corrector and place it in a 3D scanner to scan the 3D data of the tooth. The orthodontist will design a customized correction trajectory and plan according to the actual tooth condition of each person, and print the different stages of the tooth model with a 3D printer every 2 weeks, and finally produce it with a vacuum forming machine. An invisible braces with corrective effect. Users only need to wear different stages of braces to gradually correct the teeth to the desired position.

It is reported that invisible braces are the most cutting-edge orthodontic products at present. At present, there are three invisible correction brands including Meimei in China, and the equipment and materials used are imported from abroad. Taking the United States as an example, the scanning precision of 0.015mm and the printing precision of 0.025mm achieve a veritable "customized tooth", and the braces with a thickness of only 0.5mm can perfectly fit the teeth of each corrector. In addition, the braces are integrally formed from a transparent polymer material, which eliminates the need for brackets and wires, and becomes as concealed as contact lenses. This may be the most significant innovation brought about by orthodontics in 3D printing.

This highly conformable, transparent, invisible, removable invisible braces allows the wearer to maintain a good grooming instrument during use, even when communicating with people at close range, so that it does not affect daily life and social interaction.

It is worth mentioning that 3D data can help doctors to control the correction and progress more accurately and scientifically, to achieve soft correction, and to avoid the pain and damage caused by excessive force. The corrector can wear the braces on his own during eating and brushing, which greatly reduces the restriction on the diet during the correction process, and solves the problem that the wire bracket is easy to retain food residue and difficult to clean. This is also an important reason why many young people are willing to choose invisible correction.

Finally, the orthodontist told me that 3D scanning printing technology can meet the complex individual needs of the stomatology field, and has become the mainstream trend of customized oral medical equipment worldwide. In China, the application of 3D printing technology in orthodontics is very mature, and the low price of the industry brought by the US-based direct marketing model will also accelerate the popularization of this invisible braces.
