Introduction to Biomimetics Adhesive Dentistry with Dr. Alireza Sadr and Dr. Grant Chyz
Dental bonding revolutionized the shape and content of clinical dentistry, presenting a strong and minimally invasive alternative to the traditional materials.
The concepts of biomimetic restorations, natural tooth longevity and structural hierarchies have taken over the struggle of using stronger materials.
Polymerization shrinkage still threatens the success of all kinds of adhesive restorations. Our research methodology based on optical coherence tomography (OCT) presents a systematic approach for simulation of clinical situation in laboratory research, where the bonded restoration is subject to challenges such as shrinkage stress and fatigue loading.
The visual observations lead to a key conclusion; the success of restoring teeth with adhesive technology requires not only an optimal bonding approach, but also a strategy to mitigate the stresses and biomechanically protect the bonded interface and the dental tissue, such as with a continuous fiber laminated composite.
Such stress management is critical for restoration of structurally compromised teeth such as cracked teeth, and teeth with minimal coronal structure remaining.
