Treatment policy

Dental treatments include includes many options of therapeutic techniques. We assign top priority to providing high-quality services with each specialized technique.
We offer a full explanation before treatment. Especially when tooth grinding or surgery is required, we would present possible treatment options and explain their benefits and shortcomings sufficiently. Additionally, in treatment, we aim for improvement of a patient’s QOL using superior knowledge and techniques.

  • Temporomandibular joint disorder: treatment for the temporomandibular joint pain and occlusal disharmony
  • Articulation disorders: treatment for patients with articulation (speech) disorders caused by stroke, neurologic diseases and tissue defects caused by surgical operations
  • Maxillofacial prosthetics: to provide restoration for deficient teeth and maxilla or mandible caused by surgical operation for tumor or injury, etc.
