Meet Our Director

Meet Our Director

Meet Dr. Yuki Iwaki, director of the Yokohama Iwaki Dental

Dr. Iwaki has been engaged in the field of prosthetics that 
restores lost or damaged function of teeth and mouth. He
received his Ph.D. for research on CEREC (described below),
and after studying in Germany he has continued to deepen knowledge of prosthesis and gained much experience.

To "regain the function of your mouth" is also the basis of dental care. This is also the reason Dr. Iwaki is attracted to this field, and by establishing a firm treatment plan and cooperating with other dental fields, he takes great responsibility in the complete treatment.

Our three mottoes are: To make accurate diagnosis, to give the best treatment to all our patients, and to
communicate thoroughly with you.

By presenting the complete treatment plan in advance, we will start the treatment only after you have fully
understood the details of the treatment. , Therefore if you have any questions, please do not hesitate to ask us.

We are introducing the CEREC system, a one-day treatment for dental caries.

At Yokohama Iwaki Dental Office, we introduce a system called CEREC that produces tooth fillings and
crowns in a short time. This system can complete the treatment in a short period of time without you
waiting, so the effect of the treatment can be further enhanced.

The director himself has focused on treatment using this CEREC system from when he first became a dentist, and has treated many cases. We also participate in research presentations, lectures and writing sessions at
academic conferences to inform you more about CEREC.We are able to complete dental caries treatment
with only one appointment. If this is an opinion you would like to consider, please do not hesitate to contact us.
