Founder and Clinical Leadership

Dr. Adisorn Hanworawong founded MOS Dental in 2000 after graduating with a DDS from Chulalongkorn University. He completed a Master of Science in Implant Dentistry through the gIDE program at UCLA in 2004, and a Master of Science in Regenerative Medicine from the Faculty of Medicine at Chulalongkorn University in 2008. He has personally performed more than 3,000 dental implant procedures since 2002. In March 2019, MOS became part of Oracare Group, a Singapore-based dental network holding company, and Dr. Adisorn currently serves as both founding clinician and Chief Financial Officer of the group.

Network Scale

MOS Dental has grown from the original two-chair Siam Square practice to more than 30 branches across Bangkok and the metropolitan area, with over 400 professional staff and more than 250,000 patient visits annually across the network. The Oracare Group structure provides shared clinical protocols, procurement scale, and specialist networks that individual branches draw on while retaining local management. The Siam Square branch remains the network's longest-established location.

Invisalign Diamond Provider

MOS Dental holds Invisalign Diamond Provider status, maintained continuously since 2016 and renewed most recently in February 2025. Diamond status in the Align Technology global recognition program requires a minimum of 280 successfully completed cases annually, placing it among the higher tiers in the provider tier structure. Dr. Paega Jarungidanan, who holds a Master of Science in Orthodontics from Chulalongkorn University, leads the orthodontic program, with additional orthodontic coverage from the broader specialist team. Dr. Chanekrid Oupadissakoon, a Diplomate of the Thai Board of Oral and Maxillofacial Surgery, covers surgical cases within the oral surgery scope.

The Siam Square clinic is equipped with CT scanning for three-dimensional implant planning, a 3D intraoral scanner, and CAD-CAM technology for same-day or rapid crown fabrication. In 2024, the MOS network began integrating DeepCare AI-assisted diagnostics into clinical workflows, applying machine learning to radiographic interpretation for cavity and periodontal disease detection. The full service range covers dental implants, crowns, bridges, porcelain veneers, Invisalign clear aligner therapy, root canal treatment, wisdom tooth extraction, professional teeth whitening, scaling and root planing, fillings, dentures, and pediatric preventive care.
