Comprehensive Evaluation of Titanium, Zirconia, and Ceramic Dental Implant Materials: A Comparative Analysis of Mechanical and Esthetic Properties

Background: Dental implant materials play a pivotal role in the success of restorative dentistry. This study comprehensively compares the mechanical and esthetic properties of three commonly used dental implant materials: titanium, zirconia, and ceramic. Objective: This study aimed to provide insights into the suitability of titanium, zirconia, and ceramic for various clinical applications within implant dentistry. Methods: Ninety dental implants, 30 for each material, were selected based on their well -established usage in dental implantology. Mechanical properties, including tensile strength, modulus of elasticity, and fatigue resistance, were assessed using state-of-the-art testing machines. Esthetic properties, such as color stability and translucency, were scrutinized through immersion in staining solutions and spectrophotometer measurements. Fracture properties and biocompatibility were also evaluated. Results: Mechanical testing revealed that titanium exhibited the highest tensile strength (810 +/- 55 MPa), while zirconia demonstrated the highest modulus of elasticity (208 +/- 8 GPa). Titanium also displayed the greatest fatigue resistance (1,010,000 +/- 95,000 cycles), whereas zirconia had the highest hardness (1190 +/- 45 Vickers hardness number (VHN)). Esthetically, zirconia showed superior color stability ( Delta E: 1.7 +/- 0.2), while ceramic exhibited the highest translucency (TP%: 15.3 +/- 1.7). Zirconia presented the lowest surface roughness (0.28 +/- 0.04 mu m). Conclusion: This study provides insights into potential dental implant material performance, with zirconia emerging as a promising alternative. Future research should validate these findings in clinical settings, considering a broader array of variables and long-term outcomes.
