An interview with Hyeon-Shik Hwang

Abstract

It gives me great pleasure to interview Dr. Hyeon-Shik Hwang, an innovative orthodontist who has developed many creative techniques over his career. Dr. Hwang was born in Korea and received his DDS and PhD degrees from Yonsei University in Seoul. He is professor and chairman of the Department of Orthodontics at Chonnam National University School of Dentistry, Gwangju, Korea. Dr. Hwang, as a faculty at the university hospital, has maintained a successful clinical practice for more than 25 years. He has treated many adult patients focusing on esthetics and periodontal health and has developed many clinical techniques to improve the effectiveness and efficiency of treatment to the benefit of both the patient and practitioner. Dr. Hwang is also interested in the evaluation of facial asymmetry two- and three-dimensionally. As one of the early adopters of cone-beam volume imaging, he has given special emphasis on the management of surgical cases. He is married to Jung-Un Park with whom he has two sons. His favorite hobbies are photography and listening to music. When I was presented to him in a congress, it was a great pleasure meeting someone who I already admired for his singular work. Later on, his humbleness and knowledge made me marvel at him even more. I hope that all readers of Dental Press Journal of Orthodontics also enjoy the teachings from this brilliant Korean orthodontist! Guilherme Thiesen - interview coordinator

Minor Orthodontic Treatment Using NiTi Wire Exerting Light Force: Case Reports

“…The biggest advantage of this method is that it can attach appliances rapidly and easily on parts that need application. The difficulty in the conversion of the wire's restitution force into couple force due to the lack of a gap and the absence of brackets is addressed by using elastic NiTi wire [13,14]. This is because NiTi wire has a torsional stress that is 1/4 th -1/5 th that of stainless steel wire, sufficient strength, and low stiffness, so it can exert an ultra-light force.…”
