Clinical trial of dental implants in titanium-zirconium alloy compared to titanium

Titanium dental implants remain the gold standard for oral rehabilitation due to their biocompatibility and osseointegration. Therefore, it is of interest to enhance mechanical strength and stability in low-bone-volume cases where traditional implants may underperform. This randomized clinical trial compared Ti-Zr alloy implants versus conventional pure titanium implants in patients requiring prosthetic rehabilitation, evaluating primary stability, marginal bone loss, peri-implant inflammation and survival rates at regular intervals. Both implant types demonstrated comparable osseointegration rates and overall survival, with standardized clinical assessments conducted throughout the observation period. Ti-Zr implants exhibited superior mechanical stability and better peri-implant bone preservation, particularly in compromised low-density bone sites. Thus, we show Ti-Zr alloy implants as a reliable alternative to conventional titanium, especially for challenging cases requiring enhanced strength and reduced diameters.
