Hitotsuha Orthodontic Clinic, located in Ichihaya-cho, Aoba Ward, Yokohama, has provided clear aligner treatment since opening in 2006 as an orthodontic specialty clinic. The clinic offers diverse orthodontic treatments including clear aligners suitable for mixed dentition, wire braces using self-ligating brackets, and lingual orthodontics. With the introduction of an intraoral scanner (iTero), dental impressions are minimized. In treatment, the clinic prioritizes non-extraction approaches, expanding dental arches while promoting jaw growth, and uses clear aligners to move molars backward, thereby expanding the range where extraction can be avoided. Regarding fees, the clinic clearly presents total treatment costs before starting, and for labial wire braces offers a fixed package system with no additional charges. Initial consultation including treatment simulation is free for up to three visits, and the clinic also provides English support, accepts credit cards and electronic payments, and offers on-site parking.
