Compared with zirconia implants, a recognized ADVANTAGE of titanium implants is:

Correct answer: B. More extensive long-term evidence of osseointegration and higher fracture toughness

• A. Esthetics in thin tissue actually favor tooth-colored zirconia.
• B. Correct. Titanium has the longest, most robust track record of successful osseointegration and superior fracture resistance.
• C. The tooth-colored appearance is a zirconia advantage.
• D. Plaque affinity is comparable/biofilm differences are not titanium's main advantage.

Note: The recall was unsure and initially chose zirconia; current evidence favors titanium for documented osseointegration/strength, while zirconia's main advantage is esthetics.
