Restorative dentistry has been the backbone of treating caries and diseased tooth structure. As in any field, restorative dentistry and protocols have evolved tremendously over the last century. In the conventional approach of extension for prevention, not only is the diseased tooth structure removed but also, sound tooth structure is removed and replaced with rigid and non-responsive materials.
Evidence has shown that such treatment plans usually weaken the remaining tooth structure to subsequent fracture or a short lifespan restoration. Examples include amalgam restorations and full coverage cemented crowns.1
A recent concept proposed is biomimetic restorative dentistry. It aims to imitate nature when restoring teeth back to their original form. Diseased tooth structure is carefully repaired using advanced materials and adhesives, so the tooth retains its natural properties. The purpose of using biomimetic concepts and protocols is to conserve tooth structure and pulpal vitality, increase the longevity of restorative dental treatments and eliminate future retreatment cycles.
Specifically, biomimetic restoration aims to eliminate the need for full coverage crowns which rely on retention and resistance form. This is achieved utilising specific materials and techniques like minimally invasive adhesive protocols, to bond the tooth together in a natural manner. The high bond strengths achieved help to protect the health of the pulp, while also preventing secondary caries and further fractures. The natural flexibility and fracture resistance of the tooth are also enhanced when it is hydrated by the vital pulp.2
Biomimetic materials have various desired physical and chemical properties. Their advantages include enhanced strength, sealing, regenerative and antibacterial abilities. Moreover, many biomimetic materials have been proven to overcome limitations of previously used techniques and materials.3
