With the invention of new materials for restorative dentistry, new techniques for application were needed. Research in bonding to dentin showed bond strengths that approached the cohesive strength of a tooth, but getting this research into the hands of practicing dentists was another process entirely. As Dr. David Alleman was learning and researching new protocols in adhesive dentistry, his questions about why debonds occurred in select areas of the tooth led to his formulation of the c...

Dental research developments don’t happen overnight. The key players in dental research — university faculty, dental product manufacturers and the practitioners who adopt this research — work in varying capacities with the overall goal of improving dental outcomes for patients. Yet there is often a disconnect, slowing the lines of communication. In this episode Dr. David Alleman discusses leading universities who have contributed to the field of dental research, how dental manufacturers have ...

Dr. Charley Cox was one of the early contributors to adhesive dental research, specifically in the field of histology. During the development of adhesive dentistry, Dr. Cox studied long-term pulp health in non-human primates, identified immune responses that confirmed Martin Brannstrom’s hydrodynamic theory of pain and connected internationally with adhesive dental researchers like Takao Fusayama, Stefan Paul and Sema Belli. Dr. Cox’s dental research contributions are to this day still ...

Referred dental pain can be difficult for practitioners to diagnose without an understanding of the cause of dental pain and how teeth respond to different pathologies. Referred dental pain is caused by real symptoms that need to be treated, and in this episode Dr. David Alleman discusses types of referred dental pain, tips for diagnosing cracks under restorations and procedures for eliminating post-operative sensitivity through biomimetic restorative dentistry. Article referenced in this epi...

As new dental materials are developed, manufacturers and key opinion leaders play a role in how widely those products are adopted. Manufacturers market new products, but key opinion leaders and teachers also influence practitioners by comparing the benefits of various materials and lending their expertise. In this episode Dr. David Alleman discusses his early introduction to adhesive materials, how his role models and mentors led him to a growing network of key opinion leaders in the dental m...

Popular during the early years of adhesive dentistry, chemical-cure dentin bonding systems have since become less common with the rise of light-curing, but they still serve a purpose when restoring the pulp chambers of endodontically treated teeth. In this episode Dr. David Alleman discusses the polymerization dynamics of chemical-cure and light-cure adhesives and how that impacts their effectiveness in different aspects of a successful adhesive restoration. Article referenced in this episode...

How does peer-reviewed literature make it into the hands of practicing dentists? Sometimes it doesn’t. Other times research can be misinterpreted and applied incorrectly. The process of analyzing and applying current research is time consuming for practitioners to the point where new dental findings often fail to be widely adopted in practice. Reminiscing on his first meetings with researchers John Purk and Jack Ferracane, Dr. David Alleman discusses how synthesizing research into practical p...

Evidence-based dentistry aims to bring current dental research into daily practice, but the process of adopting new findings and translating them into protocols is a complicated and time-consuming process. Dr. David Alleman discusses how dentists should approach literature and what to keep in mind when considering adopting findings into their own practice. From his own experience of wading through the sea of dental research, Dr. David Alleman created the Biomimetic Mastership, a compreh...

Biomimetic dentistry can be defined by three main principles: preserve pulp vitality, conserve critical tooth structure and fully connect the tooth at 30 MPa or more. Mimicking nature (biomimetic) is about scientific analysis of how natural teeth function and replicating those principles during the restorative process. This isn’t art; this is science. In this episode Dr. David Alleman discusses the research behind understanding how a natural tooth functions and how practitioners can rep...

Does biomimetic dentistry mean to mimic how teeth look? It can, but there is more to it than that. Dr. David Alleman discusses the evolution of cosmetic dentistry and its intersection with minimally invasive dentistry, adhesive dentistry and biomimetic dentistry. During his own research and teaching of biomimetic dentistry, Dr. Alleman met and taught a number of cosmetic dentists, including Joe Willardson, a longtime colleague, teaching partner and friend whose life and work is remembered aft...

Adhesive dentistry has been taught in dental schools for decades and is widely used by dentists today. Bonding to a tooth offers increased adaptability of restorations, allowing for more minimally invasive treatment and preparation, but long-term success with adhesive dentistry is not a guarantee.Dr. David Alleman repeatedly saw failing composite restorations and realized that in order to improve restorative outcomes, posterior teeth needed more advanced protocols than anterior teeth. Subject...

Biomimetic restorative dentistry has been taught and practiced for over 20 years, with its roots linked to minimally invasive dentistry that started decades earlier. Minimally invasive dentistry sought to conserve tooth structure and restore only parts of the tooth affected by pathologies. With the invention of adhesive materials, adhesive dentistry showed promise in advancing minimally invasive principles with new materials that no longer required retention, but the adhesive restoration...

The wallpapering technique is a key protocol for extending the function of endodontically treated teeth. More brittle due to their reduced hydration, non-vital teeth are more prone to fracture, so using fiber in this way creates a fail-safe that prevents failure beneath the coronal portion of the tooth and reinfection of the root.Dr. David Alleman discusses how he helped pioneer this technique and other advancements in adhesive dentistry for cases with non-vital teeth in his Six Lessons Appro...

Dr. David Alleman first created his Six Lessons Approach for vital teeth, but the same conservative principles can benefit endodontically treated teeth too. Compared to traditional techniques for retention and bonding, the advanced adhesive and stress-reducing techniques of biomimetic dentistry are better suited for treating non-vital teeth, which are more brittle and susceptible to cracking than fully hydrated teeth with healthy pulps. This episode outlines how biomimetic techniques approach...

Daily dentistry, the cases you see every day, usually involves minor occlusal adjustments that can be treated quickly and predictably using the Six Lessons Approach, but biomimetic techniques can benefit more advanced occlusal cases too. In this episode, Dr. David Alleman discusses the cause of abfractions, how complex temporaries are a thing of the past and options for doctors seeking more advanced occlusal training beyond everyday cases.Articles referenced in this episode:Magne P, Bel...

Biomimetic dentistry aims to mimic a natural tooth throughout the restorative process. The last four decades of research has shown that mimicking and conserving a tooth’s natural connection to itself, its natural bond and resilience to occlusal forces and its natural defense mechanisms for infection benefits the tooth’s long-term health. This is also true for occlusion.In this episode, Dr. David Alleman discusses what all dentists can learn from a body’s natural occlusion, lost research from ...

What is the best material for enamel replacement? It depends! When selecting the material of an onlay or overlay, understanding how a natural tooth functions during occlusion is essential if your goal is biomimetic dentistry. Harder is not better, but rather mimicking a natural tooth’s bond to itself and its modulus of elasticity will aid in selecting your enamel replacement material.In this episode, Dr. David Alleman reviews ceramic, composite and gold and outlines best practices for complet...

Air abrasion functions as a conditioning step when bonding, which means it prepares the dentin or composite molecules for bonding. Dr. David Alleman discusses the progression of bonding systems for dentin adhesion and how this conditioning step evolved along with the bonding system molecules. The latest studies from researchers independent from the bonding system manufacturers show that air abrasion increases bond strengths to a level that mimics the strength at which a natural tooth is conne...

Dr. David Alleman’s landmark paper written with Dr. Pascal Magne in 2012 gave practitioners predictable steps for deep caries, and now crack, treatment without exposing the pulp. But why is preventing pulp exposures so important? Dr. Alleman discusses research about the outcomes of pulp exposures and their effect on the tooth long-term in addition to proven treatment for teeth that have had exposed pulps.Adhesive dentistry offers these teeth a second chance, but only when the seal is bonded a...

Early diagnosis and treatment of dental pathologies allows for more conservative treatments while saving patients time and money. When developing the Six Lessons Approach to Biomimetic Dentistry, Dr. David Alleman created a risk assessment for determining if teeth were at risk of caries or cracks based on pathologies and treatment history.Drawing on research from how teeth experience pain, the pulp’s immune response and how dental histology affects restoration, the risk assessment has been pr...
