Biomimetic Crown Preparation: A Conservative Strategy for Tooth Preservation in Contemporary Prosthodontics

Abstract

Conservation of natural tooth structure has become a central objective in modern restorative dentistry. Traditional crown preparation techniques frequently require extensive removal of enamel and dentin to achieve adequate mechanical retention and resistance form. Such approaches may compromise the structural integrity of the tooth and increase the risk of pulpal injury. Biomimetic restorative dentistry introduces an alternative philosophy that focuses on replicating the structural and functional characteristics of natural teeth while preserving as much healthy tissue as possible. Biomimetic crown preparation relies on adhesive bonding, minimally invasive preparation designs, and restorative materials that mimic the biomechanical properties of enamel and dentin. Advances in ceramic materials, resin cements, and digital technologies have further enabled clinicians to fabricate durable restorations with minimal tooth reduction. This approach promotes improved stress distribution, enhanced fracture resistance, and superior marginal sealing. However, the success of biomimetic restorations depends on appropriate case selection, strict adherence to bonding protocols, and careful material selection. This article reviews the principles, preparation guidelines, restorative materials, adhesive techniques, advantages, limitations, and future directions associated with biomimetic crown preparation in contemporary prosthodontics.
