Since 2018, Dr. Hayashi has been practicing at Apple Dental Clinic, a medical corporation, where he balances an active clinical practice with a strong commitment to education. In addition to providing comprehensive patient care, he plays an important role in mentoring and guiding younger dentists within the organization, reflecting his dedication to advancing clinical excellence through education.

A message from Dr. Hayashi: "Previously, I relied on other matrix systems; however, since about two years ago, after transitioning to Composi-Tight, followed by Strata-G and Quad, I have no longer struggled with composite resin restorations that lack proper proximal contact.

In addition to serving as an instructor, I also work as the Clinical Director of a medical corporation, where I am responsible for the clinical education and supervision of approximately 50 dentists. I consider it my mission to guide younger clinicians in delivering consistently high-quality, predictable treatment to patients in a simple and reproducible manner.

These products allow clinicians with varying levels of experience to achieve predictable, high-quality results, which is essential in both daily practice and clinical education."
