Located in Mizuno, Sayama City, Saitama Prefecture, Ii Dental Clinic provides dental treatment with thorough infection prevention measures. All staff members measure their temperature before work, wear masks and practice hand washing and glove changes during clinic hours, while ensuring strict disinfection with sodium hypochlorite and sterilization of instruments. Patients are asked to measure their temperature, sanitize their hands, and gargle upon arrival, and those with a temperature of 37.5°C or higher are politely asked to refrain from treatment. For orthodontic treatment, the clinic operates with a two-doctor system led by the director with over 15 years of experience and a dentist who also works at a specialized orthodontic clinic. They offer a wide range of treatments including wire braces, clear aligners, non-extraction orthodontics, and children's orthodontics. With dentists with specialized knowledge and skills on staff, they can respond quickly to any concerns or issues with orthodontic appliances.

To remove plaque and biofilm that cannot be removed through home care alone, they recommend professional care every 3-4 months, and dentists and dental hygienists provide guidance on proper brushing techniques and how to use tools.
