Nakagawa Orthodontic Clinic, located in Sagamiono, Minami-ku, Sagamihara City, Kanagawa Prefecture, is a dental clinic specializing in orthodontics. The clinic has been providing specialized orthodontic treatment in Sagamihara for over 30 years. The clinic's approach focuses on creating smiles by improving oral and facial muscle function and breathing patterns. For children's orthodontics, emphasis is placed on ensuring proper nasal breathing, efficient chewing, correct swallowing, and clear speech during the active growth phase, with treatment implemented as early as possible to enhance breathing, tongue, and chewing muscle functions while correcting tooth alignment. For temporomandibular joint, breathing, and muscle function treatments, orthodontic treatment is performed while enhancing and restoring oral muscle function, with additional training provided for tongue, oral, and breathing functions. Posture, head position, and overall skeletal, joint, and muscular issues are also considered. For wire orthodontics, devices that reduce friction between brackets and wires are used to improve tooth movement speed while minimizing pain. Shorter treatment methods such as corticotomy are also available for consultation. For clear aligner treatment, digital treatment simulation is performed after taking intraoral scans of tooth alignment and CT imaging of jaw bone, tooth roots, and temporomandibular joints. Appointments are by reservation only, and English language support is available.
