With reference to the recently developed two-layered single-piece dental implants integrating titanium alloy and zirconia, consider the following statements: 1. The fabrication method utilizes Spark Plasma Sintering (SPS) to achieve a material density of 99.5 percent. 2. In this integrated structure, the titanium alloy (Ti6Al4V) serves as the crown region for better wear resistance and aesthetics, while Yttria-stabilized zirconia (YSZ) acts as the load-bearing fixture for jawbone integration. Which of the statements given above is/are correct?
- [A] 1 only
- [B] 2 only
- [C] Both 1 and 2
- [D] Neither 1 nor 2
▶ Reveal Official Answer & Analytical Explanation
Statement 1 is correct because the fabrication method employs Spark Plasma Sintering (SPS) which successfully achieved a material density of 99.5 percent. Statement 2 is incorrect because their roles are reversed in the structure: the titanium alloy (Ti6Al4V) serves as the load-bearing fixture for jawbone integration, whereas Yttria-stabilized zirconia (YSZ) forms the crown region for better wear resistance and aesthetics.
