Dr. Kyouhwa Park

Dr. Kyouhwa Park is a prosthodontic specialist with comprehensive clinical and academic training from Seoul National University College of Dentistry, where he completed his DDS, internship, residency, and subsequently obtained his MSD (2003) and PhD (2011) in Prosthodontics. His doctoral and clinical work span advanced restorative protocols, implant-supported prostheses, and biomaterial applications in complex rehabilitation.

From 2012 to 2017, Dr. Park served as an Adjunct Professor in the Department of Prosthodontics at Seoul National University, contributing to postgraduate education, clinical training, and research development in implant prosthodontics. Since 2008, he has directed Prime Dental Clinic, with a focus on evidence-based prosthodontic and implant therapy.

Dr. Park holds Diplomate status with the International Congress of Oral Implantologists (ICOI) and maintains active professional membership in the Academy of Osseointegration (AO) and the Korean Academy of Oral & Maxillofacial Implantology (KAOMI). He is also the inventor of the Point UV Implant System, reflecting his ongoing commitment to innovation in implant surface technology and prosthetic integration.

Ideal osseointegration in today’s clinical environment could be defined as the rapid yet stable establishment of direct bone–implant contact that supports long-term functional performance without biological compromise.

However, conventional titanium implants undergo time-dependent biological aging after manufacturing that leads to diminished blood and cellular responsiveness, ultimately impairing the early phases of osseointegration and decreasing overall clinical predictability. Ultraviolet (UV) photofunctionalization of titanium implants was introduced to overcome these limitations and facilitate truly ideal osseointegration. UV treatment effectively removes surface hydrocarbons, converts the titanium surface charge from negative to positive, and markedly enhances hydrophilicity. Consequently, UV-treated implants demonstrate significantly improved blood wettability, protein adsorption, and cellular interactions, including enhanced osteoblast recruitment, attachment, and activity at the implant interface. These biological advantages accelerate early bone formation, increase bone-to-implant contact, and contribute to superior stability throughout both early healing and long-term functional loading.

This presentation will outline the biological concept and clinical criteria of ideal osseointegration, elucidate the mechanisms and consequences of titanium surface aging, and introduce UV-activated implants as a scientifically and clinically validated approach for achieving faster, stronger, and more predictable osseointegration. Furthermore, this presentation will also discuss practical and user-friendly approaches to safely and efficiently apply ultraviolet (UV) photofunctionalization in clinical practice. The goal is to translate the proven biological benefits of UV treatment into everyday implant procedures with simplicity and consistency.
