Comparative Analysis of Ceramic Nanoparticle Properties for Biomaterials: Implications for Applications and Material Selection Using Statistical Analysis

Abstract

This study evaluates the properties of various ceramic nanoparticles (NPs) utilized in dental biomaterials, focusing on their applicability in clinical settings. An 8 × 8 comparative analysis was conducted on key properties, including particle size, surface area, porosity, density, mechanical strength, biocompatibility, thermal stability, and cost. The materials examined include zirconia, alumina, hydroxyapatite, bioglass, silica, titania, calcium phosphate, and glass ceramics. Zirconia showed superior mechanical strength (1200 MPa) and thermal stability (1500°C), making it a leading candidate for load-bearing applications. Hydroxyapatite (HA) showed optimal biocompatibility (rating of 10), supporting its suitability for applications requiring integration with biological tissues. Alumina and bioglass showed promising attributes in terms of surface area and porosity, essential for enhancing the interaction with biological environments. The results highlight the importance of selecting the appropriate ceramic nanoparticle based on specific application requirements in dental biomaterials. This analysis provides valuable insights for researchers and clinicians in the field of dental materials, facilitating informed decisions in the development and application of advanced biomaterials tailored to enhance patient outcomes. Future studies should aim to explore the long-term performance and clinical efficacy of these materials in real-world scenarios. Statistical analysis identified strong correlations (r=0.85-0.89) between porosity, surface area, and mechanical strength, with PCA explaining 89 variance in material properties. © 2026 The Author(s).
