Kramasu Dental Clinic (Kosyun Medical Corporation) is located on the 5th floor of a building in the Kotoni area of Nishi Ward, Sapporo. This clinic specializes in general dentistry and dental metal allergy treatment. The clinic's key feature is its comprehensive approach, which goes beyond simply removing metals from the oral cavity. Director Norihiro Kuramasu, with over 10 years of clinical experience, emphasizes a three-step process of "accurate diagnosis, removal from the body, and optimal treatment." The clinic has introduced "Oligoscan" to measure the balance of toxic heavy metals and minerals accumulated in the body. Additionally, they have equipped "DermaDrop," a state-of-the-art German medical device designed to alleviate skin symptoms such as eczema, atopic dermatitis, and dark spots, which often persist after metal removal. For periodontal disease and root canal treatment, the clinic employs light-based sterilization therapy. They also offer a wide range of dental services including dentures, teeth whitening, and clear aligner orthodontics. The staff can communicate in English, and parking is available. The clinic is closed on Sundays, holidays, and during the year-end and New Year holidays.
