Location
Speaker
Asso. Prof Dr Ghee Seong Lim
Associate Professor Dr. Lim Ghee Seong graduated with a Bachelor of Dental Surgery from University of Malaya, Kuala Lumpur in 2008. He then pursued his Master in Clinical Dentistry, specializing in Restorative Dentistry at Newcastle University, Newcastle Upon Tyne, United Kingdom, where he graduated with distinction. He has also been awarded the International Training Fellowship (Prosthodontics) from the Royal College of Surgeons (England). His passion for teaching then led him to join the Faculty of Dentistry, University of Malaya and he has since become a valuable lecturer and clinical specialist in prosthodontics in the Department of Restorative Dentistry. He is currently the coordinator for removable prosthodontic undergraduate year 5, a member of the undergraduate module on occlusion and the multidisciplinary team for the TMD clinic.

Abstract :
This lecture explores the evolving role of flexible dentures in modern prosthodontics, highlighting their growing popularity due to superior aesthetics, comfort, and adaptability over conventional acrylic and cobalt-chromium prostheses. Despite their widespread use, flexible dentures are notably absent from dental school curricula, raising important educational questions. We will define flexible dentures, examine the unique properties of thermoplastic materials, and discuss their indications and contraindications. Key design principles, fabrication techniques, and patient selection criteria will be covered. The lecture also addresses the aesthetic and functional benefits of flexible dentures, alongside challenges such as repair difficulties and long-term maintenance. A critical discussion will explore why these dentures are prevalent in private practice but rarely taught in formal education, considering factors like material science limitations and traditional prosthodontic philosophies. A comparative analysis of flexible and conventional dentures will provide a balanced perspective, equipping clinicians with insights to make informed decisions about their use.
Learning objectives :
- Define flexible dentures and describe the key properties of thermoplastic materials that differentiate them from conventional acrylic or cobalt-chromium prostheses.
- Identify the indications and contraindications for prescribing flexible dentures to ensure appropriate patient selection.
- Get an overview of the clinical workflow, including design principles, fabrication techniques, and patient issuance protocols for flexible dentures.
- Analyze the advantages and limitations of flexible dentures, including their impact on aesthetics, comfort, durability, and maintenance.
- Discuss the reasons for the limited inclusion of flexible dentures in dental school curricula and discuss potential implications for prosthodontic education and practice.
