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 after news of his passing in January 2025. Our thoughts and sympathies are with his family and friends.Send us a textNew 2025 training programs announced:Biomimetic Mastership - class starts February 10.

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. Subjected to higher forces of occlusion and with deeper restored defects, understanding polymerization dynamics is essential to a long-lasting adhesive posterior restoration. His research of these principles served as the basis for him developing his Six Lessons Approach to Biomimetic Restorative Dentistry.Article referenced in this episodeGibbs CH,  Mahan  PE,  Mauderli  A,  Lundeen  HC,  Walsh  EK.

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 restorations still fell short. Teeth are more complex than many other materials that are adhesively connected, so simply bonding the restoration to the tooth did not yield long-term success.In this episode Dr. David Alleman discusses how minimally invasive dentistry paved the way for the more conservative approaches we use today, how biomimetic dentistry made adhesives more predictable, allowing for longer-lasting bonds, and where cosmetic dentistry fits in to the adhesive dentistry spectrum.Send us a textNew 2025 training programs announced:Biomimetic Mastership - class starts February 10.

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 Approach to Biomimetic Restorative Dentistry.Articles referenced in this episode:Deliperi S, Alleman D, Rudo D.

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 endodontically treated teeth differently and the research that supports these protocols.Articles referenced in this episode:Kishen A., Vedantam S.

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.

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 the last few decades and approaches for daily occlusal techniques that can be applied to cases doctors regularly see in their office.Articles referenced in this episode:Michael C.

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 completing the final steps of a biomimetic restoration.Articles referenced in this episode:Wendt, S.

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 connected to itself (30-50 MPa). This conditioning technique is what brings dentin bond strengths into the biomimetic range, maximizing bond strength and the longevity of the restoration.Articles referenced in this episode:Urabe I, Nakajima S, Sano H, Tagami J.

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 at the nanometer level, like with biomimetic dentistry. Just like each step in the Six Lessons Approach to Biomimetic Dentistry, the protocols for treating pulp exposures offer predictable results and protect the tooth’s long-term vitality.Article referenced in this episode:Thompson T., Et al.
