The popular 3D printing seems to have reached the point where everything can be played, up to the spaceship, down to a complete building, a specific portrait... to become an artifact in the eyes of many trendsetters. But if you tell me now, 3D printing is the first to develop from the service for the steel teeth sister, you will believe? In fact, in the eyes of professionals, this fashionable thing is just an ordinary rapid prototyping technology. “The mainstream 3D printing portraits, the molds of objects and even the buildings on the market are actually too easy to operate. We have already done it more than 10 years ago. Before the concept of 3D printing has yet to be formed, this is A rapid prototyping technology." This is the chairman of Time Angel Biotechnology Co., Ltd. (hereinafter referred to as "Time Angel") Li Huamin. This is a company that manufactures and sells invisible appliances. In short, it is the production of an invisible appliance to replace the traditional wire braces to better achieve the purpose of correcting teeth. Li Huamin told reporters: "In fact, as early as 3D printing technology has not exploded in 2003, invisible correction has been using 3D printing technology to manufacture molds." Age Angel can use 3D printing technology to form mass production of appliances, which is said to be the only one in China. In fact, invisible orthodontic technology is also the first 3D printed product on the planet to achieve mass production. What is mass production in large quantities, which can be found in the production workshop of Times Angel located in Wuxi 2000 square meters, where 3D printing is an important part of the entire product process. Dozens of 3D printers work 24 hours a day. Every 8 hours, they are called "one pot" by the chief operating officer of the era, and the teeth are printed neatly with high-stretch composite polymer materials. Out of the pot, and then through the hot pressing technology to obtain the finished product. The number of molds that are molded from here every day is calculated in tens of thousands, and at first glance it is dense. "The most difficult thing to print in 3D printing is the teeth, because the teeth are the most irregular, and the precision is the highest. The adjustment of the printing parameters and the accuracy of the equipment must be absolutely accurate." Li Huamin said. To this end, constant temperature and humidity are strictly required even in the production plant, in order to ensure the stability and accuracy of the equipment. According to Li Huamin, the accuracy of 3D printed dental abrasives can reach 0.02mm. "People are too sensitive to changes in the teeth, even if there are slight deviations, they will feel uncomfortable and must be fine. And 3D printing of general items is very easy to achieve because of the low precision requirements." Li Huamin said. The traditional oral science aiming at 3D printing is based on the judgment of technology. As early as 2003, an occasional opportunity, Li Huamin and his father contacted the invisible orthodontic technology jointly developed by Capital Medical University and Tsinghua University in Beijing. This was their first contact with invisible teeth. The technology at the time was only a laboratory result. Although the patent was applied, there was no product, only one 3D software and a simple laser rapid prototyping machine. But Li Huamin thinks the concept is particularly good, she wants to try. So he and his father funded the technology to buy out and began to explore the possibility of moving from the laboratory to commercialization. After she got started, she discovered that the use of invisible correction instead of the traditional approach to orthodontics is a seemingly simple idea, and the doorway behind it is far more complicated than imagined. Li Huamin said that brackets and steel wires are commonly used in conventional orthodontic treatment, and the individual ability level of the doctor often determines the final result of the correction. For example, most doctors rely on past experience to master the strength of the wire, which makes it difficult for traditional fixed corrections to communicate with patients about the effects that the teeth can achieve in the future. But what the Age Angels are doing is visually showing the patient a complete treatment process through the software. Li Huamin wants to subvert the traditional approach and give doctors a lot of unpredictable problems in the process. “Now we use 3D imaging technology to design the entire treatment plan.†Chen Hao told reporters in detail that after obtaining the dental model of the case from the doctor, the model was digitized by high-precision CT scanning technology, and then the computer software was used. To diagnose and design, that is, to simulate the whole correction process, the whole process from the original model before correction to the final state model after correction can be presented on the computer one by one, and the personalized correction plan becomes a group of groups. 3D model. Then, a highly stretchable composite polymer material is used to make an appliance in 3D printing for each process. These invisible appliances can move the teeth by applying appropriate and controllable force on the teeth, thereby correcting the teeth. The process becomes a matter of changing to a series of appliances. However, Li Huamin told reporters that the entire design and production process before the completion of the appliance involves five interdisciplinary subjects: stomatology, computer science, biomechanics, 3D printing, and materials science. It is definitely a difficult bone in technology research and development. For example, her clinical medicine and 3D software design have no precedent for reference, and it is entirely up to the team to develop it. How to accurately calculate and realize the positional movement during each step of the tooth treatment through the three-dimensional design is also a difficult point. In addition, in the back-end 3D printing, the degree of decay, rigidity, and strength of the printed materials used are different. These material property factors need to be taken into account when designing a personalized correction plan, and in the production process of 3D printing. The tip of the tooth requires a higher precision. In Europe and the United States, about 25% of patients will wear invisible appliances to correct their teeth, but the current proportion in China is only 2%. Li Huamin saw a huge development space in the industry. In fact, since 2010, Angel's income has grown at a rate of 300% per year. Currently, there are more than 36,000 customers and more than 6,000 medical institutions in the country. The direct benefit of the case accumulation is that Age Angel now has the largest database of invisible orthodontic teeth in Asia, which not only provides rich research data for subsequent corrections, but also greatly shortens the entire process time in the future. According to reports, the current response speed of the Age Angel is that after getting the patient case, the program can be issued within 24 hours, and the patient can get the finished product within 15~20 days. However, with the accumulation of data and further breakthroughs in technical capabilities, Li Huamin envisioned that in the future, as long as the patient's teeth were directly scanned and transmitted to the computer, the corrective treatment plan would be automatically formed. After 5 minutes, the 3D printed dental model might have been Take it in your hand.
