Evolving Concepts in Dental Materials: From Biocompatibility to Bioactivity
Main Article Content
Abstract
The field of dental materials has transitioned from focusing solely on biocompatibility to emphasizing bioactivity, marking a paradigm shift in restorative and regenerative dentistry. Biocompatibility, defined as the ability of a material to perform its function without eliciting adverse reactions, laid the foundation for traditional dental materials like amalgam, gold, and ceramics. However, the advent of bioactive materials, which actively interact with the oral environment to promote healing and tissue regeneration, has revolutionized the landscape. This article reviews key innovations, including glass ionomer cements, bioactive composites, and calcium silicate cements, highlighting their mechanisms such as ion release, biomimicry, and cellular interaction.
The applications of these materials span restorative dentistry, endodontics, implantology, and orthodontics, addressing challenges like material stability, cost implications, and clinical adoption. Emerging technologies, including nanotechnology, 3D printing, and smart materials, are paving the way for personalized, patient-specific treatments. This review underscores the transformative potential of bioactive dental materials, offering insights into their current status and future prospects in advancing oral health care.
