Evolution of Dental Bonding Systems
The podcast delves into the evolution of dental bonding systems, tracing back to early mentors like Ray Birdlady and John Kois. Through seeking out scientific articles and guidance, the speaker discovered the significance of adhesive approaches in dental restorations. The discussion highlights the transition from chemical cure initiators to photo-activated systems like the liner bond one, emphasizing the importance of polymerization reactions and monomer selection.
Historical Impact of GPDM Molecule
The podcast explains the history behind the GPDM molecule, initially patented in 1951 for dental bonding systems. It details how contamination affected the molecule's bonding properties and led to unintended self-etching characteristics. The narrative covers the synthesis challenges faced by Japanese companies in replicating the GPDM molecule's successful polymerization, showcasing the impact of early chemical compositions on dental bonding outcomes.
Advancements in Bonding Systems
The discussion progresses to the development of bonding systems like Optibond FL, utilizing the optimal GPDM molecule. It explores the transition from total etch techniques to hybrid layers, highlighting the role of molecules like MDP in creating effective bonds with dentin. The podcast underscores the innovative shift towards photo activation in bonding processes, leading to the establishment of gold standard systems like SE bond post-patent expiration in 2015.
A long-lasting dental restoration comes down to molecules. Dr. David Alleman breaks down the research timeline of developing adhesives that can bond to dentin, and you don’t have to share his love of chemistry to appreciate how impactful that is to the field of dentistry.
These adhesives were available to dentists as early as 1951, but just using an adhesive containing a proven molecule does not guarantee success in a dental restoration.
Understanding materials and how they interact with a natural tooth are part of Lessons 3 and 4 in Dr. David Alleman’s Six Lessons Approach to Biomimetic Restorative Dentistry. These lessons turn discussions about molecules’ interaction with dentin into actionable steps for practitioners.
