Comparative study finds PEEK devices withstand orthodontic forces better than stainless steel, suggesting a shift in usage.
Although stainless steel exhibited greater load resistance, PEEK mini-implants exceeded clinically relevant orthodontic forces (50-400 g), supporting their potential as temporary anchorage devices. Further in vivo and clinical studies are needed to confirm long-term performance.
