A machined coronal region of specific surface roughness provides resistance against plaque and biofilm accumulation, and enhances the efficacy of preventive maintenance measures, thereby decreasing the risk of peri-implantitis. Meanwhile, the complementary moderately rough portion assures the superior osseointegration of modern surfaces. This hybrid surface design enables more predictable treatment of patients suffering from progressive bone loss.
