The situation of dental technicians in Japan and Korea is roughly the same, and the restorers in both countries are called dental technicians. After World War II, dental technicians were at the bottom of society. After decades of struggle, it has gradually entered the track of legalization and standardization. Both countries have enacted the Law on Dental Technicians, which strictly stipulates the business scope and industry access system of technicians. All personnel engaged in the work of dental technicians must be graduates of dental technician schools (three-year junior college in Korea and three-year junior college in Japan) and pass the qualification examination. Germany adopts the method of combining school education with technical college training. After graduating from junior high school, I went to the dental technical school, trained in the mechanic room, studied while working, and returned to school for exams regularly. Generally graduated in 4-5 years. Pass the examination to obtain the qualification of junior dental technician. Continue to study in the College of Dental Technology and Engineering, and fully master the theory and technology of dental technicians. 8 ~ 10 years later, I will take the master of arts and crafts exam. Only those who have won the title of mechanic master are eligible to apply for the establishment of mechanic office. Therefore, the number of dental technicians in Germany is small and the scale is not large, but the technical level is very high. The Canadian Institute of Dental Technology has a three-year academic system. There are more dental clinics in Canada and fewer technicians, and the ratio is 10: 1. There is no vicious competition between technical colleges. The denture processing fees of foreign dental technicians are uniformly stipulated. At the end of 1970s, there were 10 health schools in China offering stomatology and stomatology technology. In 1980s, Beijing Medical College and Shanghai Railway Medical College successively set up three-year junior college classes for dental technicians. 1990 The School of Stomatology of the Fourth Military Medical University opened a three-year stomatology major. In 2005, Peking University, Sichuan University, Jilin University and the Fourth Military Medical University began to recruit four-year undergraduate students majoring in prosthodontics. At present, nearly 100 technical secondary schools and junior colleges offer stomatology and prosthodontics, among which Xi 'an Biomedical College offers prosthodontics, the most distinctive vocational training major in northwest China. . .
