Changshu Yuhui Dental Hospital has 27 sets of Shanghai Liku high-grade intelligent dental treatment tables (all equipped with oral endoscopy system), Siemens digital panoramic X-ray machine, oral CT, Siemens digital dental film machine, the U.S. sandblasting machine and so on. In terms of sterilization, we purchased a fully automatic sterilizer from Germany and took the lead in installing the original German central suction system in Changshu. The application of this advanced internationalized conceptual standard makes it possible to effectively control cross-infection between patients and doctors during the treatment process.
