Dr. Niles Guichet passed away peacefully at St. Joseph Hospital on January 18, 2022 following complications from dementia and a fall.

Niles Guichet was born in Baton Rouge, Louisiana. He was allowed to start college, LSU, before he graduated from high school. With this early start, he graduated from Loyola Dental School in New Orleans at the age of 22 with the highest scholastic average in his class.

Upon graduation he served one year in the U.S. Navy as a dental intern in the San Diego Naval Hospital. Having narrowly missed being sent to Korea, he instead was transferred to the El Toro Marine base in Southern California to complete his last two years of service in the Navy Dental Corps.

Upon leaving the service he began private practice in Anaheim, California -- the fastest growing city in the United States. He was in private practice for only 12 years. During those years, he founded Denar and developed a dental Instrument System including the Denar D5A Fully Adjustable Articulator, Pantograph and Field Inspection Gauge. He was awarded 16 patents related to occlusion instrumentation.

The next 18 years were spent presenting hundreds of postgraduate continuing education courses for practicing dentists and educators throughout North and South America, Europe, Australia, Asia and Iran.

In 1986, after both of his sons finished their Prosthodontic training, he opened a new office in Orange and practiced together with them until he retired in 2011. After retirement, Dr. Gregory Guichet and Dr. David Guichet assumed his practice.

He has served as President of two prestigious national organizations, the American Equilibration Society and the American Academy of Esthetic Dentistry. He was a Diplomate of the American Board of Prosthodontics.

The American College of Prosthodontists presented him with the prestigious Dan Gordon Award in recognition of lifetime achievements and contributions at the highest level to the advancement of the College and Prosthodontics, dentistry, science and the health professions. The Pacific Coast Society for Prosthodontists honored him with the Life Member Achievement Award. The Academy of Prosthodontics honored him with the Distinguished Service Award.

He is survived by his wife of 67 years, Emily, and children.
Dr. Gregory Guichet (Denise), Eric Guichet (Terri), Emily Anne Guichet (Randy Muncy) and Dr. David Guichet (Dr. Jacinthe Paquette).
Six grandsons. Michael (Nikki), Andrew, Brendon (Kaylin), Christopher,
