Our Dentists are Innovators in Patient Care

Sharing a passion for advancing holistic dentistry, Drs. Doi and Hartwell are proud to have developed numerous techniques and practices for patient safety and comfort. These include:

  • A safety loop for crowns to prevent swallowing them during fittings
  • A technique of eliminating the primary failure of implants, which has been widely embraced by other dentists
  • The concept of body propping, which is a technique Dr. Doi developed to make dental appointments more relaxing. On behalf of Bucky Pillow, he promoted the practice nationally to other dentists
  • The use of ceiling art, which Dr. Doi first employed more than 25 years ago and later, worked with designers to incorporate the feature into the construction of North Hawaii Community Hospital
  • The development of Hawaiian print scrubs, which Dr. Doi led the industry in creating more than 30 years ago
