Located in Sagamiono, Minami-ku, Sagamihara City, Nishikawa Dental Clinic is a medical facility that provides comprehensive dental care based on the principles of maxillofacial physiology. This dental clinic offers general dentistry, oral surgery, as well as temporomandibular joint disorder (TMJ) treatment and implant treatment for comfortable occlusion. The clinic places particular emphasis on TMJ treatment, guiding patients suffering from indeterminate complaints such as headaches and stiff shoulders toward improvement through treatment if TMJ is the underlying cause. According to a 2019 survey, approximately 90% of patients with suspected TMJ symptoms have shown improvement within insurance-covered treatment. For those complaining of migraines, the clinic first performs differential diagnosis to determine whether it is masticatory muscle pain and whether it should be treated dentally. Supporting this treatment system is technical expertise in creating ideal occlusion, for which the clinic holds a patent. The clinic maintains an attitude of improving all treatment areas by likening comprehensive dental care to a "bucket." In terms of infection control, the clinic implements cleaning with sodium hypochlorous acid, continuous operation of air purifiers, and regular ventilation. Payment methods include credit cards and electronic payments, and medical consultations in English are also available.
