Fig. 6From: Effects of implant thread design on primary stability—a comparison between single- and double-threaded implants in an artificial bone modelBone debris at the contact interfaces. a Numbers of debris particles. b Number and size of debris particles. Each dot indicates a debris particle, and dashes indicate median particle sizes. Particle sizes: small, < 1000 μm2; medium, 1000–10000 μm2, and large, ≥ 10,000 μm2. c Particle size distributionBack to article page
