Prof. Hyo-sang Park | Dentistry | Research Excellence Award 

Kyungpook National University | South Korea

Professor Hyo-Sang Park, DDS, MSD, PhD, is a distinguished orthodontist and academic leader with over three decades of contributions to orthodontic science, education, and clinical innovation. He currently serves as Professor and Chair of the Department of Orthodontics at the School of Dentistry, Kyungpook National University (KNU), Daegu, Republic of Korea, where he has played a pivotal role in advancing both fundamental and applied orthodontic research. Professor Park’s research career is deeply rooted in biological responses to orthodontic tooth movement, with early work focusing on immunohistochemical analysis of neurotransmitter expression during orthodontic force application. His experimental studies using animal models, particularly rats, have significantly enhanced the understanding of craniofacial growth, bone remodeling, and tissue adaptation under orthodontic conditions. These foundational investigations have provided important insights into the biological mechanisms underlying orthodontic treatment efficiency and stability. A central and defining theme of Professor Park’s research is the development and clinical application of titanium microscrews and micro-implant anchorage systems (MIA). For over 24 years, he has been a leading researcher and clinician in this field, conducting extensive animal experiments and clinical trials to optimize micro-implant design, placement protocols, and biomechanical applications. His work has contributed substantially to the global adoption of microscrew anchorage as a reliable and minimally invasive solution for complex orthodontic movements, reducing the need for patient compliance and extraoral appliances. Professor Park’s research excellence has been internationally recognized, including the CDABO Case Report of the Year Award (2005) from the American Association of Orthodontists and the American Journal of Orthodontics and Dentofacial Orthopedics, as well as multiple honors from the Korean Association of Orthodontists.

Dr. Young Joon Cho | Dentistry | Best Review Paper Award 

Kyungpook National University, School of Dentistry | South Korea

Dr. Young Joon Cho, DDS, PhD, is a highly respected periodontist and clinician–scientist whose research profile reflects nearly three decades of sustained contributions to periodontology, implant dentistry, and regenerative oral science. His academic training at Kyungpook National University, complemented by advanced postgraduate exposure through the Perio-Implant Program at the University of Pennsylvania and a visiting scholarship at Columbia University, has shaped a research career that integrates biological science, biomaterials, and advanced clinical therapeutics. His scholarly work is firmly grounded in translational research, consistently bridging fundamental biological mechanisms with evidence-based clinical solutions. Dr. Cho’s early research focused on growth factors and tissue regeneration, including pioneering studies on basic fibroblast growth factor (bFGF) and BMP-derived synthetic peptides, which clarified their roles in periodontal ligament cell proliferation and bone formation. These foundational investigations contributed to the evolving field of periodontal tissue engineering and laid the groundwork for his later emphasis on regenerative therapies. Over time, his research scope expanded to encompass periodontal regeneration, peri-implant biology, and implant-related complications, addressing clinically relevant challenges faced by contemporary implant dentistry. A central theme of Dr. Cho’s recent scholarship is the optimization of regenerative strategies in periodontitis and peri-implantitis management. His systematic reviews and meta-analyses on membrane-assisted regenerative therapy and peri-implantitis surgery provide high-level evidence that informs clinical decision-making and surgical protocol design. These works critically reassess long-standing assumptions regarding barrier membranes and regenerative materials, contributing to more predictable and biologically sound treatment approaches. In parallel, his studies on socket preservation, sinus grafting, and immediate implant placement reflect a continuous effort to refine implant timing, site development, and long-term stability. Dr. Cho has also demonstrated leadership in applying advanced diagnostic and predictive frameworks to periodontal disease. His recent work analyzing the 2017 Periodontitis Classification proposes novel systems for predicting periodontal outcomes, supporting personalized treatment planning and risk assessment. Additionally, his research on biomaterials and scaffolds for integrated periodontal regeneration, published in high-impact journals, highlights his engagement with cutting-edge material science and regenerative design. Complementing his research publications, Dr. Cho has authored multiple authoritative books in Korean on socket preservation, sinus grafting, peri-implantitis, and immediate implant placement, underscoring his role in knowledge dissemination and professional education. His extensive clinical experience as Director of Mac Dental Hospital further strengthens the translational relevance of his research. Overall, Dr. Young Joon Cho’s research profile is characterized by scientific rigor, interdisciplinary integration, and sustained impact on regenerative periodontology and implant dentistry, contributing meaningfully to both academic advancement and improved patient care.
