Located on the 2nd floor of the Kotoni 3-1 Building directly connected to JR Kotoni Station, Medical Corporation E-line Orthodontic Clinic specializes in orthodontic treatment by certified orthodontic specialists. For 30 years in Sapporo, they have focused exclusively on orthodontics, with specialists certified by the Japan Board Certified Orthodontist Specialists providing comprehensive diagnosis and advanced treatment techniques. One of their strengths is their extensive experience with "lingual orthodontics" (behind-the-teeth braces). They have actively adopted this technique, which generally requires higher skill than conventional front-facing braces, since the clinic's opening, earning praise from patients who prioritize aesthetics. In treatment, they emphasize patient communication, and since the clinic director and all staff members have undergone orthodontic treatment themselves, they are characterized by their attentive approach to addressing concerns and questions throughout the long-term treatment process. They also offer English-speaking services and accept credit cards and electronic payments. In addition to the convenient location directly connected to JR Kotoni Station, the building features free parking and barrier-free accessibility, creating an environment accessible to patients from diverse backgrounds. They also provide free orthodontic consultations as an opportunity for patients to easily discuss questions and concerns about tooth alignment and bite issues.
