Dr. Hayes Nance (August 14, 1893 - April 3, 1964) was an American Orthodontist known for his contributions in the field of Orthodontics with the topics related to mixed dentition. Dr. Hayes is known for developing Serial extraction in United States, as well as pioneering the development of Nance Appliance.[1]
Life
He was born in 1893 in Jackson, Tennessee . He was the youngest of five children. After his mother died in 1908, Dr. Nance attended the Webb School of Knoxville, Tennessee. During his childhood, he was involved in an accident while working in a Copper mine in Miami, Florida. While working, Hayes suffered a fall which lead to several fractures including a spinal injury. After his recovery, he married Julia Manning. He attended Northwestern University Dental School in 1919 and practiced for a short time in Arizona. He then eventually moved to Denver where he opened his own practice.
He retired in the year 1948. He married Florence Hays in 1956. He died in 1964 at his home in Pasadena, California due to a heart attack. Mrs. Nance died in 1955 also due to a heart attack.
Orthodontics
Dr. Nance wrote a paper in 1947 titled Limitations of Orthodontic Treatment which was culmination of 17 years of work he did on his patients.[2] Dr. Nance in his paper described the concept of Leeway Space. This space is usually found in human teeth after the permanent premolars in each arch have erupted. The space is about 3.5mm in mandible and 2mm in the maxillary arch. The adult premolar teeth are smaller than their predecessors, primary first and second molars. Therefore the space that is naturally created, is usually taken up by the movement of the Permanent First Molar moving mesially. Nance showed that combined width of mandibular deciduous canines, first molar and second molar is on average 1.7mm greater than that of the permanent successors on one side. The maxillary arch gets about 1mm on each quadrant. Dr. Nance developed Nance Appliance which is used to prevent upper first molars from moving forward after the maxillary first primary molar has been lost prematurely.
