Going to the hospital to see a tooth needs some psychological construction. For most people, going to the dentist is a feeling of resistance or even fear. It seems that the experience of looking at teeth is not comfortable. Before, some relatives went to pull out wisdom teeth, because the mouth is small, the operation space is not large, and the mouth is cracked, not to mention the process of pulling out wisdom teeth. When can dental care be brought up without fear and headache? Can AI technology optimize dental diagnosis and treatment? Mountains with unbalanced supply and demand If you go to the hospital, it's always overcrowded. Our medical resources are notoriously tense. When to go, they are always bustling, and the supply and demand of medical resources are seriously unbalanced. In the oral field, this phenomenon is amplified. According to the data of the 2019 white paper on eating habits and oral health released by cbndata in conjunction with ALI health and Yunnan Baiyao on August 22, 2019, the number of dental visits in China reached 300 million in 2018. However, the number of doctors and patients matched by each stomatologist in China is about 2542.37. According to institutional statistics, the total number of licensed (Assistant) stomatologists in China in 2020 was 278000, of which the number of licensed (Assistant) stomatologists accounted for 221000, accounting for 89.0%. According to the data, the total number of licensed (Assistant) stomatologists in China will be about 307000 in 2021. Behind the huge incremental demand, there is also a growing supply and demand contradiction and industry pain points: the dental industry has the following problems: high incidence rate, low visiting rate, low dental ratio, uneven medical level, long treatment cycle, and urgent need to improve patient experience, but the shortage of medical resources in oral cavity is insufficient. In order to alleviate the imbalance between supply and demand, hospitals have increased their efforts and began to invest continuously in digital and telemedicine. We know the application of AI technology in the medical field. The most common applications are medical imaging and virtual assistant. AI can also be enabled in medical big data, health management, drug R & D and preparation. In the subdivided field of oral medicine, AI can be applied to the whole process of oral disease prevention, screening, auxiliary diagnosis, treatment scheme design, patient follow-up and so on. The field of oral medicine is rich in a large number of dental X-ray image data, which is easy to be anonymous. It is very valuable in the development of dental AI radiation training system to facilitate the intervention of AI technology. Moreover, for dentists, there is no trained radiologist like other internal medicine and specialists. The image analysis of oral AI can be used as an assistant with high accuracy comparable to human beings, and become the second pair of golden eyes of dentists. In terms of nursing, AI can also help dentists improve the standard of nursing and the effect of treatment, which can not only improve efficiency, but also bring better experience to patients. AI digital empowerment in the field of Stomatology has become a new window for comfortable diagnosis and treatment. AI can almost participate in the whole process of oral diagnosis, treatment and nursing. AI shovel: full cycle diagnosis and treatment of serial dental domain Oral medicine mainly includes oral surgery (tooth extraction, dental implant, etc.), oral medicine (dental diseases, periodontal diseases, etc.), oral restoration (cast metal crown, porcelain crown, etc.), and orthodontics (correction of various dentition irregularities, etc.). The space where AI can make a difference is also within these ranges. Generally speaking, the utility of AI is the key link as an auxiliary decision-making. In the field of oral medicine, AI is most widely used, which is also related to film reading and detection. Taking the caries with the highest prevalence, the traditional diagnosis relies on X-ray dental film and direct oral examination to find occlusal caries. However, potential caries such as root caries, interproximal caries and root caries are difficult to find and easy to miss diagnosis. The AI model assisted in caries detection can replace doctors' accurate caries detection on dental films. This special AI model has higher sensitivity to caries spots than human Limited vision. Of course, in addition to the local special film reading, AI also makes a difference in the overall recognition of oral problems. After the dentist uploads the dental panorama, the AI system can identify the key structures in the panorama and dozens of possible oral problems of the patient, and automatically generate a fine personalized oral health report for the patient. At the same time, for the future development of dental diseases, we can also deduce the development trend of future diseases through digital modeling. Patients can intuitively and deeply understand their oral problems and improve the treatment rate and loss rate. In the surgical treatment of oral cavity, whether implant or surgical treatment, digital surgical design, preoperative digital three-dimensional scanning, imaging data acquisition and diagnostic analysis can be carried out. Through preoperative three-dimensional reconstruction, we can obtain comprehensive jaw and soft tissue data information of the surgical site, assist in the design and formulation of treatment plan, design and manufacture of surgical guide plate or use real-time navigation during operation, which can not only improve the accuracy of dental surgery, but also reduce surgical trauma and shorten the operation time. In terms of dental cosmetology, orthodontists quickly and accurately capture the interactive 3D images of teeth in the patient's mouth through the scanner. According to the generated 3D animation of tooth movement simulation, the algorithm of orthodontic AI system can accurately calculate the force required for each tooth movement, and ensure that the most appropriate and scientific orthodontic scheme can be determined according to the data entered by doctors, Adjust the teeth in the correct order. The whole cycle of orthodontic treatment can be completely covered by the design of scanning equipment and AI cloud orthodontic scheme in the early stage and intelligent production in the later stage. For the diagnosis and treatment in different dental fields, there are different AI system algorithms. These algorithms are based on millions of user data and the scanning accumulation of oral point cloud. In addition to AI simulation, AI film reading and AI tooth arrangement, AI models can also be imported for design and manufacturing in the later production of orthodontic appliances. In the field of Stomatology, AI covers all aspects and connects the whole cycle diagnosis and treatment of non-standard dental domain, which greatly improves the efficiency and experience of treatment. In practical clinical use, stomatological hospitals and chain dental clinics have begun to use AI advanced system. National oral AI guard Different from traditional medical treatment, the field of Stomatology has the dual attributes of medical treatment and consumption. At the same time, its market segments are relatively complex, far more than other industries, and the industry has natural barriers. This also makes fewer players participate, unlike AI medicine, which is highly competitive in other fields. On the track of AI dentists, the main players involved are entrepreneurs, including micro cloud artificial intelligence, deepcare feather medicine cabbage, frequency technology, etc. These start-ups aim at the gold mines in dental areas and use AI shovels to mine rich mines. Their main customers include traditional dental institutions, rising dental rookies and public hospitals. These powerful enterprises and hospitals invest a lot of money and manpower in R & D every year, and there is a strong growth demand for scientific and technological empowerment in the field of Stomatology. At present, the access conditions of AI and domestic dental clinics have been upgraded. According to the public information of venture deepcare, its product "Ai dentist" has been applied in more than 2000 dental medical institutions in many countries and regions. AI invisibility orthosis of micro cloud artificial intelligence also covers 20000 clinics. However, generally speaking, there are too few players entering the AI dental industry. Compared with the maturity of dental diagnosis and treatment system in European and American countries, we are still relatively backward. Our stomatological field is a dual track system, both public and private. Because dentistry is a completely non-standard category, the stomatological field includes two dimensions: health and medical beauty. There are many types of industrial segmentation, and the threshold is high and complex. It is difficult to support the whole dental industry in the closed-loop industrial structure. This is also one of the main factors for the relatively slow development of the industry. The competition of digital AI dentists is multidimensional, not only the competition at the level of core technical barriers, but also has high requirements for quality, cost, efficiency and service. The premise of large-scale (delivery capacity) is multi-dimensional collective ascension, and the technical dimension of a single point is difficult to break through. Take the polymer materials for orthodontics in the field of Stomatology as an example. It needs multidimensional coverage at the levels of elasticity, tear resistance and stain resistance, so as to make patients more comfortable to wear on the basis of ensuring the correction efficiency. The upgrading of materials needs to remain at the forefront of the industry. Otherwise, no matter how good the AI equipment and model is, a makeshift orthotic device can span the whole consumption experience. AI stomatology requires not only the accumulation of professional medical technology, but also new AI technology, equipment, ring materials and channels. The development of industry and the establishment of enterprise moat need to smooth out these key elements, and large-scale delivery can be realized. In the long run, the business scenario of AI dentists still has great room for development. AI dentists can not only be widely used as a screening and diagnosis tool in oral medical institutions, but also as an underwriting and claim verification tool for reviewing information and risk prompt. The channel of business transformation is smooth. Under the background of population aging and the improvement of oral health and medical beauty awareness, the upgrading of oral service industry is the general trend. The upgrading of precision diagnosis and treatment technology, refinement of service mode and innovation of management mode have become the rigid needs of the era of intelligent oral cavity. The value of AI lies in its universality and well-being. When the non-standard category of oral medicine has the ability of large-scale industrialization under the power of AI technology, it will reshape the oral field. It not only balances medical resources, but also brings precision medicine and comfortable experience to patients, so that doctors can return to medical treatment itself. More importantly, it can reduce costs, which also makes high dental care enter the general public and ensure the oral health of the whole people. (Xinhua News Agency)
