Traditional restorative methods often require significant removal of tooth structure to accommodate materials like amalgam or metal crowns. In contrast, biomimetic techniques emphasize minimal intervention by using adhesive materials that bond directly to the tooth surface. In cases where more extensive restoration is necessary, such as with deep cavities or fractures involving the pulp, biomimetic principles can guide the use of bioactive materials. Bioactive materials have the unique ability to release beneficial ions like calcium and phosphate, which promote remineralization and strengthen the surrounding tooth structure. This characteristic is particularly advantageous in pediatric dentistry, where maintaining the vitality of primary teeth until their natural exfoliation is crucial for proper development of the permanent dentition. This book explores a range of innovative biomimetic materials including fiber posts, zirconia, regenerative materials, self-assembling peptides, resin infiltration, and smart materials.
