The application and prospect of rare earth elements in zirconia dental materials

doi:10.11958/20252831

Abstract

Abstract:

Zirconia ceramics are considered ideal materials for dental restorations. However, at room temperature, their monoclinic crystal phase structure is prone to sintering cracks and brittleness problems. Additionally, zirconia material itself lacks biological properties such as antibacterial and anti-inflammatory effects, which limits their its clinical application. Due to their distinctive physicochemical characteristics, rare earth elements are increasingly utilized as stabilizers and multifunctional additives in advanced zirconia-based studies. This article reviews the current applications of rare earth elements in zirconia-based dental restorative materials, examines their potential value in clinical practice and explores future development trends, with the aim of providing insights for the innovation of dental restorative materials.

Key words: lanthanoid series elements, immunomodulation, guided tissue regeneration, periodontal, antibacterial activity, zirconia, crystal structure
